A variety of benzofurans and indole derivatives some with an alkynyl linker are disclosed herein. These compounds are not highly charged at physiological pH and have good bioavailability characteristics. These compounds exhibit selective or at least preferential affinity for the active sites of various sub-sets of protein tyrosine phosphatases. Some of these compounds are excellent inhibitors of
Mycobacterium
protein tyrosine phosphatase B (mPTPB) a protein tyrosine phosphatase expressed in
Mycobacterium tuberculosis
and characterized as a virulence factor in the causal agent of tuberculosis. Accordingly, many of these compounds and pharmaceutically acceptable salts thereof are useful for the treatment of diseases such as tuberculosis.
本文介绍了一系列
苯并呋喃和
吲哚衍
生物,其中一些具有炔基连接物。这些化合物在生理pH值下电荷不高,具有良好的
生物利用度特性。这些化合物表现出对各种亚集蛋白
酪氨酸磷酸酶的活性位点具有选择性或至少具有优先亲和性。其中一些化合物是良好的Mycobacterium蛋白
酪氨酸磷酸酶B(m
PTPB)的
抑制剂,这是一种在结核病的病原体Mycobacterium tuberculosis中表达的蛋白
酪氨酸磷酸酶,并被认为是一种毒力因子。因此,这些化合物和其药学上可接受的盐对于治疗结核病等疾病非常有用。
