Tang, Kai;Zhao, Min;Wu, Ya-Hong;Wu, Qiong;Wang, Shu;Dong, Yu;Yu, Bin;Song, Yihui;Liu, Hong-Min research published 《 Structure-based design, synthesis and biological evaluation of aminopyrazines as highly potent, selective, and cellularly active allosteric SHP2 inhibitors》, the research content is summarized as follows. Src homol.-2-containing protein tyrosine phosphatase 2 (SHP2) encoded by the proto-oncogene PTPN11 is the first identified non-receptor protein tyrosine phosphatase. SHP2 dysregulation contributes to the pathogenesis of different cancers, making SHP2 a promising therapeutic target for cancer therapy. In this article, authors report the structure-guided design based on the well-characterized SHP2 inhibitor SHP099, extensive structure-activity relationship studies (SARs) of aminopyrazines, biochem. characterization and cellular potency. These medicinal chem. efforts lead to the discovery of the lead compound TK-453 I, which potently inhibits SHP2 (SHP2WT IC₅₀ = 0.023μM, ΔTm = 7.01°C) in a reversible and noncompetitive manner. Compound I exhibits high selectivity over SHP2PTP, SHP1 and PTP1B, and may bind at the “tunnel” allosteric site of SHP2 as SHP099. As the key pharmacophore, the aminopyrazine scaffold not only reorganizes the cationic-π stacking interaction with R111 via the novel hydrogen bond interaction between the S atom of thioether linker and T219, but also mediates a hydrogen bond with E250. In vitro studies indicate that I inhibits proliferation of HeLa, KYSE-70 and THP-1 cells moderately and induces apoptosis of Hela cells. Further mechanistic studies suggest that I can decrease the phosphorylation levels of AKT and Erk1/2 in HeLa and KYSE-70 cells.

Myostatin is a key neg. regulator of skeletal muscle growth, and myostatin inhibitors are attractive tools for the treatment of muscular atrophy. Previously, we reported a series of 14-29 mer peptide myostatin inhibitors, including a potent derivative MIPE-1686, a 16-mer N-terminal-free L-peptide with three unnatural amino acids and a propensity to form β-sheets. However, the biol. stability in vivo of MIPE-1686 is a concern for its development as a drug. In the present study, to develop a more stable myostatin inhibitory D-peptide (MID), various retro-inverso versions of a 16-mer peptide were synthesized. Among these, an arginine-containing derivative, MID-35 shows a potent and equivalent in vitro myostatin inhibitory activity equivalent to that of MIPE-1686 and considerable stability against biodegradation The in vivo potency of MID-35 to increase tibialis anterior muscle mass in mice is significantly enhanced over that of MIPE-1686 and MID-35 can serve as a new entity for the prolonged inactivation of myostatin in skeletal muscle.

Fmoc-L-Ser-OH is a synthetic peptide that belongs to the group of glycopeptides. It is used as a model for such compounds and has been shown to have antimicrobial activity in vitro against gram-positive bacteria, especially Staphylococcus epidermidis. This compound was synthesized from 3-mercaptopropionic acid and chloride in the presence of hydroxyl groups and epidermal growth factor. The synthetic pathway can be divided into three steps: (1) condensation of 3-mercaptopropionic acid with hydrochloric acid to yield 3-mercaptoacrylic acid; (2) esterification of 3-mercaptoacrylic acid with glycine to form Fmoc-L-Ser; and (3) deprotection of Fmoc protecting group., Related Products of 73724-45-5

Suram, Dinesh;Veerabrahma, Kishan research published 《 Design and Development of Solid SMEDDS and Liquisolid Formulations of Lovastatin, for Improved Drug Dissolution and In vivo Effects-a Pharmacokinetic and Pharmacodynamic Assessment》, the research content is summarized as follows. Lovastatin (Lov) is a lipid-lowering agent, with 5% bioavailability (BA) due to extensive first pass metabolism and poor solubility To enhance dissolution and in vivo effects, Lov solid self microemulsifying drug delivery system (SMEDDS) and liquisolid systems were developed and evaluated to select superior one. Solubilities were determined in oils, surfactants, and cosurfactants. Ternary phase diagrams were constructed and selected the one which showed maximum emulsion zone. In vitro dissolution, DSC, SEM and PXRD studies were used to characterize the developed formulations. In vivo studies were conducted on optimal formulations in wistar rats. Based on solubilities, Capmul PG8 and Capmul MCM were preferred as oils, Labrasol and Transcutol P as surfactant and cosurfactant. Here, Syloid XDP carrier showed better adsorption capacity among others, hence was used in optimal solid SMEDDS (SX) and liquisolid (LS) formulations. Dissolution study results showed significant improvement in release when compared to pure drug. DSC, SEM, and PXRD results indicated the loss of drug crystallinity in optimal formulations. In pharmacokinetic (PK) study, SX and LS showed 2.57 and 1.43 fold improvements in AUC, when compared to that of coarse suspension (CS). In pharmacodynamic (PD) study, hyperlipidemia was induced by Triton X-100. CS and LS treatments showed a decline in hyperlipidemic levels at 4 h. But, SX-treated group showed early onset of decline at 2 h. Further, the duration of anti-hyperlipidemia was at least 12 h extra when compared to CS and LS. This study confirmed the superiority of SX over LS in PK and PD effects.

Suo, Haicui;Peng, Ziting;Guo, Zhiqiang;Wu, Chengjunhong;Liu, Jitao;Wang, Li;Xiao, Juan;Li, Xiaobo research published 《 Deep eutectic solvent-based ultrasonic-assisted extraction of phenolic compounds from different potato genotypes: Comparison of free and bound phenolic profiles and antioxidant activity》, the research content is summarized as follows. Potato phenolics exhibit health-promoting effects. Studies on bound phenolics are scarce. Here, significant differences in total phenolic content (TPC), total flavonoid content (TFC) and antioxidant activity in free and bound forms were found among 19 potato genotypes. 7 free and 24 bound phenolics were characterized and quantified using ultrahigh-performance liquid chromatograph-mass spectrometry, among which 22 bound phenolics are reported for the first time in potato. The number and content of identified free and bound phenolics changed considerably among the genotypes. Chlorogenic acid, cryptochlorogenic acid and rutin in free form, and benzoic and caftaric acids in bound form were predominant. Heijingang showed the highest free and total TPC and antioxidant activity, and the largest number of phenolic compounds, whereas S17-1-1 contained the highest free and total TFC and Longshu 7 contained the highest bound phenolic content. Cluster anal. segregated the genotypes into 6 groups. This study provides useful information on benefits of potato in human health.

Sun, Yanhua;Yao, Chuan;Zeng, Junliang;Zhang, Yuxiang;Zhang, Yange research published 《 Eco-friendly deep eutectic solvents skeleton patterned molecularly imprinted polymers for the separation of sinapic acid from agricultural wastes》, the research content is summarized as follows. A new and facile sinapic acid imprinted polymer coated hydroxyapatite based on deep eutectic solvents (DESs) was prepared and applied as an adsorbent material to selectively extract sinapic acid from squeezed rape seed extract Different DESs acted as functional monomers and cross-linkers in preparing MIPs. Hydroxyapatite was selected as the core and the imprinting layer was coated evenly on its surface. Batch adsorption tests indicated that the MIPs displayed superior recognition ability by possessing an adsorption capacity of 121 mg g-1. The prepared imprinted materials could be regeneratively and repeatedly used without a significant reduction in adsorption capacity. The abovementioned good performances caused the proposed method to be further applied for the selective extraction of sinapic acid in squeezed rape seed extract Compared with the previous extraction methods, the facile and eco-friendly method proposed in this work could simultaneously settle the issues “residues of toxic organic solvent” and “lack of specificity and selectivity”. Therefore, the proposed approach would provide a good candidate for the extraction of active ingredients from agricultural wastes.

Sumimoto, Yusuke;Okawa, Shinya;Inoue, Tomoya;Masuda, Kazufumi;Maruyama, Masato;Higaki, Kazutaka research published 《 Extensive improvement of oral bioavailability of mebendazole, a brick dust, by polymer-containing SNEDDS preparation: Disruption of high crystallinity by utilizing its counter ion》, the research content is summarized as follows. Poorly water-soluble and poorly lipid-soluble drugs are called as ′brick dust′ and it is very hard for them to be formulated as some dosage form which can provide an effective bioavailability after oral administration. Mebendazole (MBZ), an anti-helminthic drug having anti-cancer properties, is one of the brick dusts and its poor bioavailability has been well known. The strategy of the current study was to improve the oral absorption of MBZ by SNEDDS formulation prepared by utilizing an MBZ-counter ion complex, of which the formation would disrupt the high crystallinity of MBZ. Among five different counter ions examined, (+)-10-camphorsulfonic acid (CSA), 2-naphthalene-sulfonic acid (NSA) and p-toluenesulfonic acid (TSA) largely improved MBZ solubility in the SNEDDS vehicle by forming the complex with MBZ. The solid state of these complexes, MBZ-CSA, MBZ-NSA and MBZ-TSA, was suggested to be amorphous by XRPD and DSC. SNEDDS formulations of the three complexes extensively improved MBZ dissolution under gastric and intestinal luminal conditions, compared with MBZ crystalline powder. However, since the dissolved concentrations of MBZ were time-dependently decreased so much by precipitation, we tried to maintain the high dissolution property by applying some polymer for SNEDDS preparation of MBZ-CSA which provided the highest solubility in the SNEDDS vehicle. Among ten different polymers examined, HPMCP-50 successfully maintained the high dissolution property of MBZ-CSA SNEDDS under both gastric and intestinal luminal conditions. In the in vivo oral administration study, SNEDDS preparations for the three MBZ complexes significantly improved MBZ absorption compared with MBZ crystalline powder, but 2% HPMCP-50-containing SNEDDS of MBZ-CSA provided further improvement of MBZ absorption, resulting in around 10-fold of crystalline powder in AUC.

To prepare a topical formulation of bimatoprost (BIM) with high skin permeability, we designed a solvent mixture system composed of ethanol, diethylene glycol monoethyl ether, cyclomethicone, and butylated hydroxyanisole, serving as a volatile solvent, nonvolatile co-solvent, spreading agent, and antioxidant, resp. The ideal topical BIM formulation (BIM-TF#5) exhibited 4.60-fold higher human skin flux and a 529% increase in dermal drug deposition compared to BIM in ethanol. In addition, compared to the other formulations, BIM-TF#5 maximally activated human dermal papilla cell proliferation at a concentration of 5 muM BIM, equivalent to 10 muM minoxidil. Moreover, BIM-TF#5 (0.3% [weight/weight] BIM) significantly promoted hair regrowth in the androgenic alopecia mouse model and increased the area covered by hair at 10 days by 585% compared to the vehicle-treated mice, indicating that entire telogen area transitioned into the anagen phase. Furthermore, at day 14, the hair weight of mice treated with BIM-TF#5 (5% [weight/weight] BIM) was 8.45- and 1.30-fold greater than in the 5% (weight/weight) BIM in ethanol and 5% (w/v) minoxidil treated groups, resp. In the histol. examination, the number and diameter of hair follicles in the deep subcutis were significantly increased in the BIM-TF#5 (0.3 or 5% [weight/weight] BIM)-treated mice compared to the mice treated with vehicle or 5% (weight/weight) BIM in ethanol. Thus, our findings suggest that BIM-TF#5 is an effective formulation to treat scalp alopecia, as part of a novel therapeutic approach involving direct prostamide F2alpha receptor-mediated stimulation of dermal papilla cells within hair follicles.
