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.
3-Chlorodiphenylamine is able to bind highly (Kd=10 µM) to a chimeric protein consisting of the regulatory N-domain of cTnC (cNTnC) and the switch region of cTnI (cNTnC–cSp chimera)[1].3-Chlorodiphenylamine (100 µM) results in a 1.5-fold increase in the Ca2+ sensitivity of force development without altering the maximal or resting forces in skinned ventricular trabeculae[1].3-Chlorodiphenylamine (25-100 µM) increases Ca2+ sensitivity of the N-domain of intact cTnC after reconstitution into the cTn complex (cTnC complexed with cTnI and cTnT) in a concentration-dependent manner. It exhibits pCa50s with 6.39±0.01, 6.65±0.01, and 6.73±0.02 in the presence of 25, 50, and 100 µM 3-Chlorodiphenylamine, respectively[1].
