A series of 4-phenylthiazole derivatives were synthesized and tested their inhibitory effect on the interleukin-6 secretion stimulated by PTH in osteoblastic cells. SCRC2941-18, 2-amino-4-(4-chlorophenyl)-5-methylthiazole, was found to be the most potent inhibitor in the derivatives Furthermore, SCRC2941-18 significantly suppressed the bone weight loss in the ovariectomized mice, an osteoporosis model.

Sierra, Michael L. published the artcileSubstituted 2-[(4-Aminomethyl)phenoxy]-2-methylpropionic Acid PPARα Agonists. 1. Discovery of a Novel Series of Potent HDLc Raising Agents, Application In Synthesis of 144060-99-1, the main research area is arylmethylpropionic acid derivative SAR preparation PPAR agonist HDLc raising.

The peroxisome proliferator activated receptors PPARα, PPARγ, and PPARδ are ligand-activated transcription factors that play a key role in lipid homeostasis. The fibrates raise circulating levels of high-d. lipoprotein cholesterol and lower levels of triglycerides in part through their activity as PPARα agonists; however, the low potency and restricted selectivity of the fibrates may limit their efficacy, and it would be desirable to develop more potent and selective PPARα agonists. Modification of the selective PPARδ agonist 1 (GW501516) so as to incorporate the 2-aryl-2-methylpropionic acid group of the fibrates led to a marked shift in potency and selectivity toward PPARα agonism. Optimization of the series gave 25a, which shows EC50 = 4 nM on PPARα and at least 500-fold selectivity vs. PPARδ and PPARγ. Compound 25a (GW590735) has been progressed to clin. trials for the treatment of diseases of lipid imbalance.

Lohans, Christopher T. published the artcileBiochemical, Structural, and Genetic Characterization of Tridecaptin A1, an Antagonist of Campylobacter jejuni, COA of Formula: C10H11NS2, the main research area is sequence tridecaptin A1 paenicidin B Paenibacillus gene cluster; antimicrobial agents; bacteriocins; lipopeptides; peptides; structure elucidation.

Bacillus circulans NRRL B-30644 (now Paenibacillus terrae) was previously reported to produce SRCAM 1580, a bacteriocin active against the food pathogen Campylobacter jejuni. We have been unable to isolate SRCAM 1580, and did not find any genetic determinants in the genome of this strain. We now report the reassignment of this activity to the lipopeptide tridecaptin A1. Structural characterization of tridecaptin A1 was achieved through NMR, MS/MS and GC-MS studies. The structure was confirmed through the first chem. synthesis of tridecaptin A1, which also revealed the stereochem. of the lipid chain. The impact of this stereochem. on antimicrobial activity was examined The biosynthetic machinery responsible for tridecaptin production was identified through bioinformatic analyses. P. terrae NRRL B-30644 also produces paenicidin B, a novel lantibiotic active against Gram-pos. bacteria. MS/MS analyses indicate that this lantibiotic is structurally similar to paenicidin A.

Sharma, Swagat published the artcileDiscovery, synthesis and characterization of a series of (1-alkyl-3-methyl-1H-pyrazol-5-yl)-2-(5-aryl-2H-tetrazol-2-yl)acetamides as novel GIRK1/2 potassium channel activators, Product Details of C11H9NO2S, the main research area is pyrazolyl arylazolyl acetamide preparation GIRK channel activator SAR; Activator; G protein-regulated inwardly-rectifying potassium channel; GIRK; Tetrazole.

The study described the discovery and characterization of a series of 5-aryl-2H-tetrazol-3-yl acetamides as G protein-gated inwardly-rectifying potassium (GIRK) channels activators. Working from an initial hit discovered during a high-throughput screening campaign, a tetrazole scaffold was identified that shifts away from the previously reported urea-based scaffolds while remaining effective GIRK1/2 channel activators. In addition, the compounds were evaluated in Tier 1 DMPK assays and identified a (3-methyl-1H-pyrazol-1-yl)tetrahydrothiophene-1,1-dioxide head group that imparts interesting and unexpected microsomal stability compared to previously-reported pyrazole head groups.

Liu, Xiaobo published the artcileDesign, synthesis, and biological evaluation of [1,2,4]triazolo[4,3-a] pyrazine derivatives as novel dual c-Met/VEGFR-2 inhibitors, Synthetic Route of 144060-99-1, the main research area is triazolopyrazine preparation antitumor activity apoptosis hemolytic toxicity mol docking; antiproliferative activity; antitumor; c-Met inhibitor; pyrazine derivatives; targeted drug.

In this study, a series of novel [1,2,4]triazolo[4,3-a]pyrazine derivatives, I (R = 4-methyl-2-phenyl-1,3-thiazol-5-yl, 4-(4-methyl-1,3-thiazol-2-yl)pyridine, 3-(thiophen-2-yl)-1H-pyrazol-5-yl, etc.; R1 = H, Me; X = H, F) evaluated for their inhibitory activities toward c-Met/VEGFR-2 kinases and antiproliferative activities against tested three cell lines in vitro was designed and synthesized. Most of the compounds I showed satisfactory activity compared with lead compound foretinib. Among them, the most promising compound I (R = 1-(4-chlorophenyl)-5-(trifluoromethyl)-1H-pyrazol-4-yl, R1 = Me; X = F) (II) exhibited excellent antiproliferative activities against A549, MCF-7, and Hela cancer cell lines with IC50 values of 0.98 ± 0.08, 1.05 ± 0.17, and 1.28 ± 0.25μM, resp., as well as excellent kinase inhibitory activities (c-Met IC50 = 26.00 nM and VEGFR-2 IC50 = 2.6μM). Moreover, compound II inhibited the growth of A549 cells in G0/G1 phase in a dose-dependent manner, and induced the late apoptosis of A549 cells. Its intervention on intracellular c-Met signaling of A549 was verified by the result of Western blot. Fluorescence quant. PCR showed that compound 17l inhibited the growth of A549 cells by inhibiting the expression of c-Met and VEGFR-2, and its hemolytic toxicity was low. Mol. docking and mol. dynamics simulation indicated that compound II could bind to c-Met and VEGFR-2 protein, which was similar to that of foretinib.
