Bioactivity | Calhex 231 hydrochloride is a CaSR inhibitor via negative allosteric modulation. Calhex 231 hydrochloride blocks Ca2+-induced accumulation of [3H]inositol phosphate with an IC50 of 0.39 μM in HEK293 cells. Calhex 231 hydrochloride has the potential for diabetic cardiomyopathy (DCM) treatment[1][2]. |
Target | CaSRIC50: 0.39 μM (Inositol phosphate) |
Invitro | Calhex 231 treatment significantly decreases the proliferation of cardiac fibroblasts[1].Calhex 231 treatment significantly downregulates the CaSR, α-SMA, Col-I/III, MMP2/9 expresses. Calhex231 alleviates high glucose-induced myocardial fibrosis in cardiac fibroblasts[1].Calhex 231 could inhibit Itch (atrophin-1 interacting protein 4)-ubiquitin proteasome and TGF-β1/Smads pathways, and then depress the proliferation of cardiac fibroblasts, along with the reduction deposition of collagen, alleviate glucose-induced myocardial fibrosis[1].
