Nnamani, Petra O.;Ugwu, Agatha A.;Nnadi, Ogechukwu H.;Kenechukwu, Franklin C.;Ofokansi, Kenneth C.;Attama, Anthony A.;Lehr, Claus-Michael research published 《 Formulation and evaluation of transdermal nanogel for delivery of artemether》, the research content is summarized as follows. Nanostructured lipid carrier (NLC) formulations were prepared using optimized ART concentration of 0.25 g dissolved in 5% w/v mixture of solid (Gelucire 43/01 and Phospholipon 85G) and liquid (Transcutol) lipids at 90°C. An aqueous surfactant phase at 90°C was added (dropwise) under magnetic stirring (1000 rpm) for 5 min. The pre-emulsion was speedily homogenized at 28,000 rpm for 15 min and further probe sonicated at 60% amplitude (15 min). Resultant sample was cooled at room temperature and frozen at -80°C prior to lyophilization. The freeze-dried sample was used for solid-state characterization as well as in the formulation of transdermal nanogels using three polymers (Carbopol 971P, Poloxamer 407, and Prosopis africana peel powder) to embed the ART-NLC, using ethanol as a penetration enhancer. Transdermal ART-nanogels were characterized accordingly (phys. examination, pH, drug content, rheol., spreadability, stability, particle size and morphol., skin irritation, in vitro and ex vivo skin permeation, and anal. of permeation data), P < 0.05. Overall, ART nanogels prepared from Poloxamer 407 showed the most desirable drug permeation, pH, swellability, spreadability, viscosity, and transdermal antiplasmodial properties superior to PAPP-ANG > C971P-ANG. A two-patch/wk concurrent application of the studied nanogels could ofer 100% cure of malaria as a lower-dose (50 mg ART) patient-friendly regimen devoid of the drug’s many side efects.

Nkhata Malunga, Lovemore;Ames, Nancy;Mitchell Fetch, Jennifer;Netticadan, Thomas;Joseph Thandapilly, Sijo research published 《 Genotypic and environmental variations in phenolic acid and avenanthramide content of Canadian oat (Avena sativa)》, the research content is summarized as follows. Phenolic compounds (PC) in oat may possess health promoting properties. This study evaluated the effect of genotype, environment, and their interaction on the phenolic acid and avenanthramide (AVN) concentration in Canadian oat. Six cultivars were grown at eight locations across Canada in a randomised complete block design with three field replicates. Free PCs were extracted from oat groat flour and analyzed using a UPLC-PDA system. The cumulative concentration of free PCs and AVN ranged from 58 to 350 and 9 to 244 μg/g, resp. The effect of environment was significant (p < 0.0001) for the concentration of all PCs. Cultivar differences significantly influenced the concentration of all PCs but AVNs A and B. The growing location explained > 68% of the variation in the concentration of AVN. Thus understanding the genotypic and environmental triggers of individual PCs may help agronomists and breeders strategize in selecting and growing oat cultivars of interest.

Ninya, Nicole;Vallecillos, Laura;Marce, Rosa Maria;Borrull, Francesc research published 《 Evaluation of air quality in indoor and outdoor environments: Impact of anti-COVID-19 measures》, the research content is summarized as follows. This study monitors the presence of 88 volatile organic compounds (VOCs) and semi-volatile organic compounds (semi-VOCs) at the gas phase of seven indoor settings in a school in the city of Tarragona, Spain, and five outdoor locations around the city. The VOCs and semi-VOCs monitored were solvents (∑Solvents), aldehydes (∑Aldehydes), emerging organic compounds (∑EOCs), and other VOCs and semi-VOCs (∑Others). Passive sampling campaigns were performed using Carbopack X tubes followed by thermal desorption coupled to gas chromatog. with mass spectrometry (TD-GC-MS). Overall, 70 of the target compounds included in the method were determined in the indoor air samples analyzed, and 42 VOCs and semi-VOCs in the outdoor air samples. Our results showed that solvents were ubiquitous throughout the school at concentrations ranging from 272μg m^-3 to 423μg m^-3 and representing 68%-83% of total target compounds (∑Total). The values of ∑Total in 2021 were three times as high as those observed at the same indoor settings in 2019, with solvents experiencing the greatest increase. A plausible explanation for these observations is the implementation of anti-COVID-19 measures in the indoor settings, such as the intensification of cleaning activities and the use of hydroalcoholic gels as personal hygiene. The ∑Total values observed in the indoor settings evaluated were twenty times higher than those found outdoors. ∑Solvents were the most representative compounds found indoors (74% of the ∑Total). The concentrations of VOCs and semi-VOCs observed in the outdoors were strictly related to combustion processes from automobile traffic and industrial activities, with ∑Others contributing 58%, ∑Solvents 31%, and ∑Aldehydes 11% of the ∑Total. EOCs, on the other hand, were not detected in any outdoor sample.

Nilova, Aleksandra;Sibbald, Paul A.;Valente, Edward J.;Gonzalez-Montiel, Gisela A.;Richardson, H. Camille;Brown, Kevin S.;Cheong, Paul Ha-Yeon;Stuart, David R. research published 《 Regioselective Synthesis of 1,2,3,4-Tetrasubstituted Arenes by Vicinal Functionalization of Arynes Derived from Aryl(Mes)iodonium Salts》, the research content is summarized as follows. Herein, the synthesis of 1,2,3,4-tetrasubstituted benzenoid rings, motifs found in pharmaceutical, agrochem., and natural products, is described. In the past, the regioselective syntheses of such compounds have been a significant challenge. This work reports a method using substituted arynes derived from aryl(Mes)iodonium salts to access a range of densely functionalized 1,2,3,4-tetrasubstituted benzenoid rings. Significantly, it was found that halide substituents are compatible under these conditions, enabling post-synthetic elaboration via palladium-catalyzed coupling. This concise strategy is predicated on two regioselective events: 1) ortho-deprotonation of aryl(Mes)iodonium salts to generate a substituted aryne intermediate, and 2) regioselective trapping of said arynes, thereby improving previously reported reaction conditions to generate arynes at room temperature and in shorter reaction times. D. functional theory (DFT) computations and linear free energy relationship (LFER) anal. suggest the regioselectivity of deprotonation is influenced by both proximal and distal ring substituents on the aryne precursor. A competition experiment further reveals the role of arene substituents on relative reactivity of aryl(Mes)iodoniums as aryne precursors.

Niederhafner, Petr;Safarik, Martin;Neburkova, Jitka;Keiderling, Timothy A.;Bour, Petr;Sebestik, Jaroslav research published 《 Monitoring peptide tyrosine nitration by spectroscopic methods》, the research content is summarized as follows. Oxidative stress can lead to various derivatives of the tyrosine residue in peptides and proteins. A typical product is 3-nitro–tyrosine residue (Nit), which can affect protein behavior during neurodegenerative processes, such as those associated with Alzheimer′s and Parkinson′s diseases. Surface enhanced Raman spectroscopy (SERS) is a technique with potential for detecting peptides and their metabolic products at very low concentrations To explore the applicability to Nit, we use SERS to monitor tyrosine nitration in Met-Enkephalin, rev-Prion protein, and α-synuclein models. Useful nitration indicators were the intensity ratio of two tyrosine marker bands at 825 and 870 cm^-1 and a bending vibration of the nitro group. During the SERS measurement, a conversion of nitrotyrosine to azobenzene containing peptides was observed The interpretation of the spectra has been based on d. functional theory (DFT) simulations. The CAM-B3LYP and ωB97XD functionals were found to be most suitable for modeling the measured data. The secondary structure of the α-synuclein models was monitored by electronic and vibrational CD (ECD and VCD) spectroscopies and modeled by mol. dynamics (MD) simulations. The results suggest that the nitration in these peptides has a limited effect on the secondary structure, but may trigger their aggregation.

Nguyen, David;Secretan, Philippe-Henri;Cotteret, Camille;Jacques-Gustave, Emmanuelle;Greco, Celine;Bodemer, Christine;Schlatter, Joel;Cisternino, Salvatore research published 《 Stability and Formulation of Erlotinib in Skin Creams》, the research content is summarized as follows. Recent studies have highlighted the benefit of repurposing oral erlotinib (ERL) treatment in some rare skin diseases such as Olmsted syndrome. The use of a topical ERL skin treatment instead of the currently available ERL tablets may be appealing to treat skin disorders while reducing adverse systemic effects and exposure. A method to prepare 0.2% ERL cream, without resorting to a pure active pharmaceutical ingredient, was developed and the formulation was optimized to improve ERL stability over time. Erlotinib extraction from tablets was incomplete with Transcutol, whereas DMSO (DMSO) allowed 100% erlotinib recovery. During preliminary studies, ERL was shown to be sensitive to oxidation and acidic pH in solution and when added to selected creams (i.e., Excipial, Nourivan Antiox, Pentravan, and Versatile). The results also showed that use of DMSO (5% v/w), neutral pH, as well as a topical agent containing antioxidant substances (Nourivan Antiox) were key factors to maintain the initial erlotinib concentration The proposed ERL cream formulation at neutral pH contains a homogeneous amount of ERL and is stable for at least 42 days at room temperature in Nourivan cream with antioxidant properties.

Nezir, Ayca Ece;Khalily, Melek Parlak;Gulyuz, Sevgi;Ozcubukcu, Salih;Kucukguzel, S. Guniz;Yilmaz, Ozgur;Telci, Dilek research published 《 Synthesis and evaluation of tumor-homing peptides for targeting prostate cancer》, the research content is summarized as follows. High toxicity caused by chemotherapeutic drugs and the acquisition of drug resistance by cancer cells are the major drawbacks in cancer therapy. A promising approach to overcome the posed barriers is conjugating tumor-homing peptides to drugs or nanocarriers. Such high-affinity peptides can specifically target surface markers overexpressed by cancer cells, ensuring a rapid and cancer-specific uptake of the drugs. Since prostate-specific membrane antigen (PSMA) is overexpressed by aggressive prostate cancer cells, targeting this surface protein with peptide conjugates can lead to the development of effective strategies against prostate cancer. In this study, we aimed to determine which PSMA-binding peptide among peptides 563, 562 and 9-mer, show the highest selectivity towards PSMA using 22Rv1 prostate cancer cells, a cell line with moderate PSMA levels. Tumor-homing peptides were synthesized by fluorenylmethoxycarbonyl-based solid-phase peptide synthesis (Fmoc-SPPS) strategy, and evaluated for their prostate cancer cell-specific targeting efficiencies by flow cytometry. Our results showed that the PSMA-binding capacity of peptide 563 was superior to those of 562, 9-mer, and 5-mer; therefore, can be utilized as a potent-targeting agent not only in the treatment of high PSMA pos. but also moderate PSMA pos. prostate cancer tumors.

Apelin receptor agonism improves symptoms of metabolic syndrome. However, endogenous apelin peptides have short half-lives, making their utility as potential drugs limited. Previously, we had identified a novel pyrazole-based agonist scaffold. Systematic modification of this scaffold was performed to produce compounds with improved ADME properties. Compound 13 (I) with favorable agonist potency (cAMPi EC₅₀ = 162 nM), human liver microsome stability (T_1/2 = 62 min), and pharmacokinetic profile in rodents was identified. The compound was tested in a mouse model of diet-induced obesity (DIO) and metabolic syndrome for efficacy. Treatment with 13 led to significant weight loss, hypophagia, improved glucose utilization, reduced liver steatosis, and improvement of disease-associated biomarkers. In conclusion, a small-mol. agonist of the apelin receptor has been identified that is suitable for in vivo investigation of the apelinergic system in DIO and perhaps other diseases where this receptor has been implicated to play a role.
