novel thienopyrimidinone analog was discovered as a potent and highly selective TAK1 inhibitor using the SBDD approach. TAK1 plays a key role in inflammatory and immune signaling, so TAK1 is considered to be an attractive molecular target for the treatment of human diseases (inflammatory disease, cancer, etc.). After the hit compound had been obtained, our modifications successfully increased TAK1 inhibitory
使用SBDD方法发现了一种新型的噻吩并嘧啶酮类似物,作为一种有效且高度选择性的TAK1抑制剂。TAK1在炎性和免疫信号传导中起关键作用,因此TAK1被认为是治疗人类疾病(炎性疾病,癌症等)的有吸引力的分子靶标。获得命中化合物后,我们的修饰成功提高了TAK1的抑制活性和溶解度,但代谢稳定性仍然不理想。为了提高代谢稳定性,我们进行了代谢鉴定。尽管所获得的代谢物幸运地是一种强效的TAK1抑制剂,但其激酶选择性却很低。随后,为了实现高激酶选择性,我们使用SBDD遵循两种策略:一种针对TAK1中独特的氨基酸残基,特别是Ser111和Asn114的组合;另一种针对TAK1中的独特氨基酸残基。另一个减少了TAK1中铰链位置与Tyr106的相互作用。不出所料,我们设计的化合物在超过420种激酶的内部和市售面板分析中均显示了出色的激酶选择性,并保留了其强大的TAK1抑制活性(TAK1 IC50 = 11nM)。
