3-Chlorodiphenylamine 是一种高亲和力的心肌 Ca2+ 增敏剂 (Ca2+ sensitizer)。3-Chlorodiphenylamine 基于二苯胺结构，可与心肌肌钙蛋白 C (cTnC) 的 N 端结构域可以结合 (Kd=6 μM)。3-Chlorodiphenylamine 由于分子体积小，可以作为开发更强 Ca2+ 增敏化合物的极好起始支架，用于收缩性心力衰竭的研究。 3-Chlorodiphenylamine is a high affinity Ca2+ sensitizer of cardiac muscle. 3-Chlorodiphenylamine is based on diphenylamine and binds to the isolated N-domain of cardiac troponin C (cTnC) (Kd=6 μM). 3-Chlorodiphenylamine is an excellent starting scaffold for the development of more potent Ca2+-sensitizing compounds due to its small size, and can be used for systolic heart failure research.
