N-(2-苯氧基)乙基咪唑并[1,2 - a ]吡啶-3-羧酰胺类新型抗结核药的设计,合成及生物学活性
摘要:
根据在我们实验室中发现的WZY02的结构,设计并合成了一系列N-(2-苯氧基)乙基咪唑并[1,2 - a ]吡啶-3-甲酰胺(IPAs),作为新型抗结核药物。结果表明,它们中的许多对药物敏感性MTB菌株H37Rv和耐药性临床分离株均表现出优异的体外抑制活性,且纳摩尔摩尔MIC值低。化合物15b和15d显示出良好的安全性和药代动力学特征,表明它们有望成为未来抗结核药物发现的先导化合物。
Microwave Assisted Synthesis of Disubstituted Imidazo[1,2-a]pyridine-3-carboxylic Acid Esters
摘要:
A novel and efficient synthetic method leveraging microwave-assisted organic synthesis (MAOS) to prepare disubstituted imidazo[1,2-a]pyridine-3-carboxylic acid esters (IPCEs) (3a-z), the key intermediates for a class of novel anti-tuberculosis agents, is reported. Under microwave heating at 120 degrees C for 20 or 30 min, the condensations of 2-aminopyridines (1a-k) and ethyl 2-halogenated acetoacetates (2a-d) were conveniently performed in ethanol with acceptable yields.
A series of N-(2-phenoxy)ethyl imidazo[1,2-a]pyridine-3-carboxamides (IPAs), based on the structure of WZY02 discovered in our lab, were designed and synthesized as new anti-TB agents. Results reveal that many of them exhibit excellent in vitro inhibitory activity with low nanomolar MIC values against both drug-sensitive MTB strain H37Rv and drug-resistant clinical isolates. Compounds 15b and 15d display
