Synthesis of 2-substituted-6,8-dichloro-3,4-dihydro-3-oxo-2H-1,4-benzothiazine-1,1-dioxides and -1-oxides as glycine-NMDA receptor antagonists
摘要:
A number of 2-substituted-3,4-dihydro-3-oxo-6,8-dichloro-2H-1, 4-benzothiazine-1,1-dioxides (1-2a-b) and -1-oxides (3-4a-b) bioisosters of RPR 104632 in which the 3-carboxylic group was replaced by a carbonyl group were synthesized. Comparative in vitro pharmacological studies on this series of RPR 104632 analogs were performed using receptor binding assays. None of these compounds showed detectable binding affinity for the glycine-NMDA receptor.

unrecognized binding site on the aldosereductase (AR) enzyme with strong affinity for benzothiazoles was pursued for the design of novel, potentaldosereductaseinhibitors (ARIs). The first application of this hypothesis led to a novel series of 3,4-dihydro-4-oxo-3-(benzothiazolylmethyl)-1-phthalazineacetic+ + + acids. The parent of this series (207) was a potentinhibitor of AR from human placenta (IC50

against nontuberculous mycobacteria and Mycobacterium tuberculosis, numerous hits were identified with moderate activity. Extensive medicinal chemistry optimization has led to a series of potent benzothiazole amide antimycobacterial agents. Replacement of the adamantylgroup with cyclohexyl derivatives and further development of this series resulted in an advanced lead compound, CRS400393, which demonstrated
通过对市售非结核分枝杆菌和结核分枝杆菌文库的高通量筛选,鉴定出许多具有中等活性的命中。广泛的药物化学优化产生了一系列有效的苯并噻唑酰胺抗分枝杆菌药物。用环己基衍生物取代金刚烷基,并进一步开发该系列,产生了先进的先导化合物CRS400393 ,它表现出优异的效力和分枝杆菌特异性的活性谱。针对脓肿分枝杆菌和其他快速生长 NTM 的 MIC 值范围为 0.03 至 0.12 μg/mL,针对鸟分枝杆菌复合体的 MIC 值范围为 1-2 μg/mL。初步作用机制研究表明这些药物可能以 MmpL3(一种分枝杆菌分枝菌酸转运蛋白)为目标。该系列已在脓肿分枝杆菌感染的概念验证小鼠模型中证明了体内功效。

development of newer better and safer agents. Herein, we report nine novel benzothiazole derivatives based on structure-based drug discovery and molecular modelling approaches. Material and methods : Newly designed compounds were synthesized following a four-step reaction and were characterized for structural confirmation. These novel compounds were evaluated on the MTT assay for their in vitro efficiency
