In vitro study | 3-Chlorodiphenylamine is able to bind highly ( K d =10 µM ) to a chimeric protein consisting of the regulatory N-domain of cTnC (cNTnC) and the switch region of cTnI ( cNTnC–cSp chimera ).3-Chlorodiphenylamine (100 µM) results in a 1.5-fold increase in the Ca 2+ sensitivity of force development without altering the maximal or resting forces in skinned ventricular trabeculae.3-Chlorodiphenylamine (25-100 µM) increases Ca 2+ 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 pCa 50 s 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. |
Risk Codes | 20/21/22 - Harmful by inhalation, in contact with skin and if swallowed. |
Safety Description | S28 - After contact with skin, wash immediately with plenty of soap-suds. S36/37 - Wear suitable protective clothing and gloves. |
Biological activity | 3-Chlorodiphenylamine is a high-affinity myocardial Ca2 + sensitizer (Ca2 + sensitizer). 3-Chlorodiphenylamine is based on the diphenylamine structure and can bind to the N-terminal domain of cardiac troponin C (cTnC) (Kd = 6 µM). Due to its small molecular size, 3-Chlorodiphenylamine can be used as an excellent starting scaffold for the development of stronger Ca2 + sensitizing compounds for the study of systolic heart failure. |
target | Kd: 6 µM (N-domain of cardiac troponin C (cTnC))Kd: 10 µM (cNTnC-cSp chimera) |
use | m-chlorodiphenylamine is an organic intermediate of diphenylamine used to produce chlorpromazine. |
Production method | It is obtained by condensation of o-chlorobenzoic acid and m-chloroaniline, and then decarboxylation of iron powder. |
