As the result of a rhJNK1 high throughput screening, the imidazo[1,2-a]quinoxaline I was identified as a 1.6 μM rhJNK1 inhibitor. Optimization of this compound lead to AX13587, II (X = none), (rhJNK1 IC50 = 160 nM) which was co-crystallized with JNK1 to identify key mol. interactions. Kinase profiling against 125+ kinases revealed AX13587 was an inhibitor of JNK, MAST3, and MAST4 whereas its methylene homolog AX14373, II (X = CH2), (native JNK1 IC50 = 47 nM) was a highly specific JNK inhibitor.

Estrogen-related receptor α (ERRα) is an orphan nuclear receptor that has been functionally implicated in the regulation of energy homeostasis. Herein is described the development of diaryl ether based thiazolidenediones, which function as selective ligands against this receptor. Series optimization provided several potent analogs that inhibit the recruitment of a coactivator peptide fragment in in vitro biochem. assays (IC50 < 150 nM) and cellular two-hybrid reporter assays against the ligand binding domain (IC50 = 1-5 μM). A cocrystal structure of the ligand-binding domain of ERRα with lead compound 29 (I) revealed the presence of a covalent interaction between the protein and ligand, which has been shown to be reversible. In diet-induced murine models of obesity and in an overt diabetic rat model, oral administration of 29 normalized insulin and circulating triglyceride levels, improved insulin sensitivity, and was body weight neutral. This provides the first demonstration of functional activities of an ERRα ligand in metabolic animal models.

The actual development and clin. use of new therapeutics for tuberculosis have remained stagnant for years because of the complexity of the disease process, the treatment of which at present requires the administration of drug combinations over a 6 mo period. In this study, the chem. and biol. of a series of potent 5-(2-methylbenzothiazol-5-yloxymethyl)isoxazole-3-carboxamides, e.g. I [R = Me2N, 1-piperidinyl, (S)-MeO2CCH(Ph)NH, etc.] , which proved to be active against replicating Mycobacterium tuberculosis (Mtb) H37Rv, are reported. The most potent compounds I [R = (S)- or (R)-MeO2CCH(Ph)NH] were found to inhibit Mtb growth at micromolar concentrations, with MIC values of 1.4 and 1.9 μM, resp. Impressively, all active compounds were nontoxic toward Vero cells (IC50 > 128 μM). Moreover, the best of these compounds were also tested against protozoan parasites, and some of these compounds were found to show activity, especially against Plasmodium falciparum. These studies thus suggest that certain 2-methylbenzothiazole based compounds may serve as promising lead scaffolds for further elaboration as antitubercular drugs and as possible antimalaria drugs.Ethyl 2-amino-2-thioxoacetate(cas: 16982-21-1HPLC of Formula: 16982-21-1) was used in this study.
