吡咯并[2,3 - a ]咔唑-3-甲醛是有效的具有体外抗增殖活性的Pim激酶抑制剂。在本研究中,我们报告了新的4-取代的吡咯并[2,3- a ]咔唑的合成和生物活性(Pim激酶抑制作用和体外抗增殖能力)。结果表明,对于在4位带有甲氧基羰基的吡咯并[2,3- a ]咔唑,在3位没有甲酰基,可以保持Pim激酶抑制能力(特别是Pim-3)。此外,发现对Pim-1和Pim-3激酶具有活性的化合物27在微摩尔范围内显示出抗增殖活性。

A mild one-step synthetic method to access privileged heterobiaryl pyrazolo[3,4-b]pyridines from indole-3-carboxaldehyde derivatives and a variety of aminopyrazoles has been developed. This novel method constructs heterobiaryls with the wide scope of substrate generality and excellent regioselectivity via indole ring opening.
