Breast cancer is the most common cancer of women, and fifth leading cause of mortality worldwide. Existing breast cancer regimens are costly and produce severe side effects. This highlights a need for the development of efficient novel therapies, which are cost effective and limit side effects. An elec. pulse (EP)-based chemo therapy, known as electrochemotherapy (ECT) using the natural compound curcumin could be an effective alternative. ECT is a non-surgical modality, which produces excellent anti-tumor efficacy at small drug concentrations due to increased uptake of drugs. In clinics, ECT is shown to be effective in treating advanced, recurrent, and metastatic breast cancers, which are refractory to multiple modalities. ECT with curcumin triggers apoptotic cell death in breast cancer cells and could be an effective alternative, due to curcumin’s low cost and reduced side-effects. However, there is a lack of studies quantifying the uptake of curcumin in response to EP application. Towards this, we determined the uptake of different curcuminoids (curcumin, desmethoxycurcumin, and bisdemethoxycurcumin) upon EP application and their impact on cell cytotoxicity. Addnl., we studied the combined effect of calcium chloride (CaCl₂) and a curcuminoids (Cur) mixture, based on initial studies suggesting calcium electroporation as a potential inexpensive anti-cancer treatment. Our results indicate EP with Cur increases cellular uptake, cell shrinkage, and cytotoxicity. The EP + Cur resulted in the highest uptake of the bisdemethoxycurcumin. Further, EP also potentiated the cytotoxicity of CaCl₂ and of the Cur and CaCl₂ combination against breast cancer cells and caused apoptosis. Our preliminary data pave the way to further studies on Cur and CaCl₂ combination treating breast cancer. This study involved multiple reactions and reactants, such as Bisdemethoxycurcumin (cas: 33171-05-0COA of Formula: C19H16O4).

Bisdemethoxycurcumin (cas: 33171-05-0) belongs to ethers. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.COA of Formula: C19H16O4

Estrogenic activity of lignin-derivable alternatives to bisphenol A assessed via molecular docking simulations was written by Amitrano, Alice;Mahajan, Jignesh S.;Korley, LaShanda T. J.;Epps, Thomas H. III. And the article was included in RSC Advances in 2021.Formula: C13H12O2 The following contents are mentioned in the article:

Lignin-derivable bisphenols are potential alternatives to bisphenol A (BPA), a suspected endocrine disruptor; however, a greater understanding of structure-activity relationships (SARs) associated with such lignin-derivable building blocks is necessary to move replacement efforts forward. This study focuses on the prediction of bisphenol estrogenic activity (EA) to inform the design of potentially safer BPA alternatives. To achieve this goal, the binding affinities to estrogen receptor alpha (ERα) of lignin-derivable bisphenols were calculated via mol. docking simulations and correlated to median effective concentration (EC50) values using an empirical correlation curve created from known EC50 values and binding affinities of com. (bis)phenols. Based on the correlation curve, lignin-derivable bisphenols with binding affinities weaker than ∼-6.0 kcal mol-1 were expected to exhibit no EA, and further anal. suggested that having two methoxy groups on an aromatic ring of the bio-derivable bisphenol was largely responsible for the reduction in binding to ERα. Such dimethoxy aromatics are readily sourced from the depolymerization of hardwood biomass. Addnl., bulkier substituents on the bridging carbon of lignin-bisphenols, like di-Et or dimethoxy, were shown to weaken binding to ERα. And, as the bio-derivable aromatics maintain major structural similarities to BPA, the resultant polymeric materials should possess comparable/equiv thermal (e.g., glass transition temperatures, thermal decomposition temperatures) and mech. (e.g., tensile strength, modulus) properties to those of polymers derived from BPA. Hence, the SARs established in this work can facilitate the development of sustainable polymers that maintain the performance of existing BPA-based materials while simultaneously reducing estrogenic potential. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Formula: C13H12O2).

Synthesis and property of alkyl dioxyethyl α-D-xyloside was written by Wu, Xiubing;Kuang, Na;Chen, Langqiu;Fan, Yulin;Fu, Fang;Li, Jiping;Zhang, Jing. And the article was included in Journal of Molecular Liquids in 2020.Synthetic Route of C10H22O3 The following contents are mentioned in the article:

Due to the inherent defects of the long alkyl chain in the related hydrophilicity and water solubility, alkyl α-D-xylosides (7) had hardly the practical application as sugar-based surfactants and should be reconstructed to obtain alkyl dioxyethyl α-D-xylosides (5) with dioxyethylene fragment (-(OCH₂CH₂)_2-) as the hydrophilic spacer to increase the related TPSA value. With D-xylose as the raw material, 1,2-cis alkyl dioxyethyl α-D-xylosides (5a-5f, n = 6-12) were stereoselectively synthesized. Their physicochem. properties including water solubility, surface tension, foamability, emulsification, thermotropic liquid crystal, and hygroscopicity had been investigated. Their water solubility was found to decrease gradually whereas their calculated HLB numbers were 14.72 → 11.67 (n = 6 → 12) with increasing alkyl chain length (n). Dodecyl dioxyethyl α-D-xyloside (5f) had not water solubility because the HLB number was low. Furthermore, their CMC values decreased with increasing the alkyl chain length, and the CMC value of decyl dioxyethyl α-D-xyloside (5e) was as low as 9.21 x 10^-5 mol·L^-1. Octyl dioxyethyl α-D-xyloside (5c) had the lowest surface tension (27.25 mN·m^-1) at the CMC. Both of nonyl and decyl dioxyethyl α-D-xylosides (5d & 5e) possessed good foaming power and foam stability. Decyl dioxyethyl α-D-xyloside (5e) had the strongest emulsifying property either in the toluene/water system or in the octane/water system. Nonyl dioxyethyl α-D-xylosides (5d) had the most stylish SA texture. Hexyl dioxyethyl α-D-xyloside (5a) possessed the strongest hygroscopicity. Therefore, the alkyl dioxyethyl α-D-xylosides as a class of novel sugar-based surfactants will be widely considered as promising candidates for various practical applications. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Synthetic Route of C10H22O3).

2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

A number of new nido-carboranyl amidines 10-R(CH₂)_nNHC(Et):HN-7,8-C₂B₉H₁₁ (n = 2, R = OH, OMe, and NMe₂; n = 3, R = OH) were synthesized by the nucleophilic addition of amino alcs. and N,N-dimethylethylenediamine to the highly activated -CN⁺ – triple bond of the 10-propionitrilium derivative of nido-carborane. A similar reaction of 10-EtCN-7,8-C₂B₉H₁₁ with ethylenediamine unexpectedly resulted in the cleavage of the CN bond to form the ammonium derivative 10-H₃N-7,8-C₂B₉H₁₁. The complexation of the synthesized carboranyl amidines 10-MeO(CH₂)₂NHC(Et):HN-7,8-C₂B₉H₁₁ and 10-Me₂N(CH₂)₂NHC(Et):HN-7,8-C₂B₉H₁₁ with Ni and Pd phosphine complexes [(Ph₃P)₂MCl₂] (M = Ni, Pd) was studied. The reactions with 10-MeO(CH₂)₂NHC(Et)HN-7,8-C₂B₉H₁₁ result in half-sandwiched metallacarborane complexes with the retention of one PPh₃ ligand [3-Ph₃P-3-(8-MeOCH₂CH₂N:C(Et)NH)-3,1,2-MC₂B₉H₁₀], while the reactions with 10-Me₂N(CH₂)₂NHC(Et):HN-7,8-C₂B₉H₁₁ proceed with the complete loss of the phosphine ligands and give complexes with the η⁵:κ²(N,N’)-coordinated carboranyl amidine ligand [3,3-(8-Me₂NCH₂CH₂N:C(Et)NH)-3,1,2-MC₂B₉H₁₀].

Integrative transcriptomic and metabolomic analyses provide insight into the long-term submergence response mechanisms of young Salix variegata stems was written by Zhang, Qingwei;Tang, Shaohu;Li, Jianqiu;Fan, Chunfen;Xing, Libo;Luo, Keming. And the article was included in Planta in 2021.HPLC of Formula: 33171-05-0 The following contents are mentioned in the article:

Salix variegata Franch. is a riparian shrub species that can tolerate long-term complete submergence; however, the mol. mechanisms underlying this trait remain to be elucidated. In this study, we subjected S. variegata plants to complete submergence for 60 d and collected stems to perform transcriptomic and metabolomic analyses, as well as quant. reverse transcription-polymerase chain reaction (qRT-PCR) assays. Results revealed that photosynthesis and the response to light stimulus were inhibited during submergence and recovered after desubmergence. Ethylene and abscisic acid (ABA) signaling could be important for the long-term submergence tolerance of S. variegata. Jasmonic acid (JA) signaling also participated in the response to submergence. Raffinose family oligosaccharides, highly unsaturated fatty acids, and specific stress-related amino acids accumulated in response to submergence, indicating that they may protect plants from submergence damage, as they do in response to other abiotic stressors. Several organic acids were produced in S. variegata plants after submergence, which may facilitate coping with the toxicity induced by submergence. After long-term submergence, cell wall reorganization and phenylpropanoid metabolic processes (the synthesis of specific phenolics and flavonoids) were activated, which may contribute to long-term S. variegata submergence tolerance; however, the detailed mechanisms require further investigation. Several transcription factors (TFs), such as MYB, continuously responded to submergence, indicating that they may play important roles in the responses and adaptation to submergence. Genes related to oxidative stress tolerance were specifically expressed after desubmergence, potentially contributing to recovery of S. variegata plants within a short period of time.

Developing consensus on content and format of e-portfolio for MHPE students: A Delphi study. was written by Ansar, Ambreen;Yasmeen, Rahila;Rizvi, Robina Mushtaq. And the article was included in JPMA. The Journal of the Pakistan Medical Association in 2022.HPLC of Formula: 2380-78-1 The following contents are mentioned in the article:

OBJECTIVE: To build a consensus on portfolio framework for master’s in health professional education students and document programme learning outcomes, tasks for students related to each outcome, and the pieces of evidence regarding the completion of each task. METHODS: The modified Delphi study was conducted from February to July 2020 at Riphah International University, Islamabad, Pakistan, and comprised a three-round electronic-based survey of faculty members associated with the master’s in health professional education programme, alumni, and current students as well as portfolio experts. The panellists had to choose from 10 programme learning outcomes, 75 tasks for students to achieve those outcomes, and 510 pieces of evidence to confirm that the tasks had been done to achieve the outcomes. A consensus cut-off of ≥80% was decided to select the item. RESULTS: Of the 45 stakeholders approached, 41(91.5%) responded in round 1. Of them, 31(75.6%) responded in round 2, while round 3 comprised responses from 31(96.7%) subjects. The draft template was originally derived from the master’s in health professional education programme guide, expert opinions, and systematic literature review available for portfolios of other higher education degrees. The list of items was refined through a pilot study. The final template was approved by the expert panel after 3 iterations. The final list of items included 59 (78.6%) tasks and 105(21%) pieces of evidence related to all the 10 programme learning outcomes. CONCLUSIONS: The important programme learning outcomes, their related tasks, and the required pieces of evidence to be added in the e-portfolio of master’s in health professional education programme students were identified, and recommendations for the format of implementation and assessment were given. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1HPLC of Formula: 2380-78-1).

4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.HPLC of Formula: 2380-78-1

The effect of benzenesulfonamide′s side chains on their human carbonic anhydrase I/II inhibitory activities was written by Yang, Chaofu;Sun, Xianyu;Li, Zhan;Cheng, Yunyun;Lei, Yu;Lu, Liang;Liu, Xuan;Zhuang, Xiaomei;Wang, Tao;He, Xinhua. And the article was included in Journal of Molecular Structure in 2022.Quality Control of 2-Methoxyethylamine The following contents are mentioned in the article:

Benzenesulfonamides are well-known potent carbonic anhydrase inhibitors (CAIs). They are usually composed of benzenesulfonamide heads and hydrophobic side chain tails. However, hydrophobic side chain tails contribute to poor water solubility, which is a major challenge in the development of CAIs. Herein, to elaborate whether benzenesulfonamides with hydrophilic/hydrophobic tails are effective against carbonic anhydrases (CAs), 12 benzenesulfonamides containing hydrophilic tails and 16 benzenesulfonamides containing hydrophobic tails were designed and synthesized. Benzenesulfonamides with hydrophilic tails including 4b, 4c, and 5b and benzenesulfonamides with hydrophobic tails including 2e, 4b, and 4c are potent carbonic anhydrase I/II dual inhibitors whose Ki to CA I and CA II were below 10 nM, and below 50 nM, resp. However, the water solubility of 4b, 4c, and 5b was 52, 148, and 71 mg/100 g of water, resp., which is much better than that of benzenesulfonamides with hydrophobic tails. In a hypoxic mouse model, compounds 4c and 5b extended the survival of mice by 34.46% and 28.23%, resp., compared to the blank control. Treatment with 4c and 5b extended survival better than acetazolamide treatment did (16.86%). Moreover, 5b also has better anti-convulsant effect than AAZ. Mol. docking anal. demonstrated that hydrogen bonds between the oxygen atoms in the hydrophilic tails of 4b, 4c, and 5b and H2O in hCA I and hCA II protein facilitated ligand-receptor binding. Therefore, considering the good water solubility and potent CA I/II inhibition, 4c and 5b are worth exploring as therapeutic options for acute mountain sickness. In conclusion, benzenesulfonamides containing hydrophilic tails could offer innovative opportunities for potent, water-soluble anti-AMS (Acute Mountain Sickness) compounds This study involved multiple reactions and reactants, such as 2-Methoxyethylamine (cas: 109-85-3Quality Control of 2-Methoxyethylamine).

Derivatization of inhibitor of apoptosis protein (IAP) ligands yields improved inducers of estrogen receptor α degradation was written by Ohoka, Nobumichi;Morita, Yoko;Nagai, Katsunori;Shimokawa, Kenichiro;Ujikawa, Osamu;Fujimori, Ikuo;Ito, Masahiro;Hayase, Youji;Okuhira, Keiichiro;Shibata, Norihito;Hattori, Takayuki;Sameshima, Tomoya;Sano, Osamu;Koyama, Ryokichi;Imaeda, Yasuhiro;Nara, Hiroshi;Cho, Nobuo;Naito, Mikihiko. And the article was included in Journal of Biological Chemistry in 2018.Formula: C13H12O2 The following contents are mentioned in the article:

Aberrant expression of proteins often underlies many diseases, including cancer. A recently developed approach in drug development is small mol.-mediated, selective degradation of dysregulated proteins. The authors have devised a protein-knockdown system that utilizes chimeric mols. termed specific and nongenetic IAP-dependent protein erasers (SNIPERs) to induce ubiquitylation and proteasomal degradation of various target proteins. SNIPER(ER)-87 consists of an inhibitor of apoptosis protein (IAP) ligand LCL161 derivative that is conjugated to the estrogen receptor α (ERα) ligand 4-hydroxytamoxifen by a PEG linker, and the authors have previously reported that this SNIPER efficiently degrades the ERα protein. Here, the authors report that derivatization of the IAP ligand module yields SNIPER(ER)s with superior protein-knockdown activity. These improved SNIPER(ER)s exhibited higher binding affinities to IAPs and induced more potent degradation of ERα than does SNIPER(ER)-87. Further, they induced simultaneous degradation of cellular inhibitor of apoptosis protein 1 (cIAP1) and delayed degradation of X-linked IAP (XIAP). Notably, these reengineered SNIPER(ER)s efficiently induced apoptosis in MCF-7 human breast cancer cells that require IAPs for continued cellular survival. The authors found that one of these mols., SNIPER(ER)-110, inhibits the growth of MCF-7 tumor xenografts in mice more potently than the previously characterized SNIPER(ER)-87. Mechanistic anal. revealed that the authors’ novel SNIPER(ER)s preferentially recruit XIAP, rather than cIAP1, to degrade ERα. The authors’ results suggest that derivatized IAP ligands could facilitate further development of SNIPERs with potent protein-knockdown and cytocidal activities against cancer cells requiring IAPs for survival.

The synthesis and characterization of polyethers and volatile, low-melting polyether complexes of bis(1,1,1,5,5,5-hexafluoro-2,4-pentanedionato)barium Ba(hfa)₂·RO(CH₂CH₂O)_nR’ where R = R’ = Me, n = 3; R = Me, R’ = Et, n = 3; R = R’ = H, n = 5, 6; R = R’ = Me, n = 4; R = Me, R’ = Et, n = 5; R = Me, R’ = Bu, n = 5, 6; R = Me, R = C₅H₁₁O, n = 3; R = Me, R’ = n-C₆H₁₃, n = 4, 5; R = Et, R’ = Bu, n = 5; R = Bu, R’ = Bu, n = 4, 6; R = Bu, R’ = n-C₆H₁₃, n = 5 are reported. The complexes are conveniently synthesized by reaction of n-propylammonium⁺hfa^– in DMF with an aqueous solution of Ba(NO₃)₂ and the polyether or, alternatively, by reaction of the polyether with Ba(hfa)₂ in toluene. These new complexes were characterized by elemental anal., FTIR, ¹H, ¹³C, and ¹⁹F NMR, MS, x-ray diffraction (Ba(hfa)₂·CH₃O(CH₂CH₂O)₃CH₃·H₂O, Ba(hfa)₂·CH₃O(CH₂CH₂O)₅C₂H₅), and TGA. The m.ps. of the complexes are strongly dependent on the architecture of the polyether chain and dimensions of the terminal polyether substituent, with the lowest m.ps. corresponding to the longest polyethers having the largest terminal groups. The volatility of the Ba(hfa)₂·polyether compounds is dependent on mol. weight and mol. structure; however, there is little direct correlation between m.p. depression and enhanced volatility. The applicability of these complexes in metal-organic CVD is demonstrated by the successful growth of phase-pure BaTiO₃ thin films using Ba(hfa)₂·CH₃O(CH₂CH₂O)₅C₂H₅ as the Ba source. Phase composition and epitaxy in these films is analyzed by energy-dispersive x-ray spectroscopy and x-ray diffraction Θ-2Θ, ω, and φ scans.
