Calhex 231
Based on 6 publication(s) in Google Scholar
Calhex 231 is a potent negative allosteric modulator that blocks (IC50 = 0.39 μM) increases in [3H]inositol phosphates elicited by activating the human wild-type CaSR transiently Ca2+-sensing receptor. Calhex 231 can be used in the study of traumatic hemorrhagic shock (THS) and diabetic cardiomyopathy (DCM).

Biological Activity
Calhex 231 dose-dependently inhibited the IP response induced by 10 mM Ca2+ with a potency in the T764A (IC50 = 0.28 ± 0.05 μM) and H766A (IC50 = 0.64 ± 0.03 μM) mutant receptors similar to that in the WT receptor[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[2].
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[2].

Cell Line:Primary neonatal rat cardiac fibroblasts (CFs).
-
Concentration:3 µM.
-
Incubation Time:24 hours.
-
Result:Significantly decreased the proliferation of cardiac fibroblasts.
Calhex-231 (Cal, 0.1-1 mg/kg) has a mitigating effect on traumatic hemorrhagic shock by improving vascular hyporesponsiveness and reducing mitochondrial dysfunction[3].

-
Animal Model:Male Wistar rats (8 weeks old) injected with Streptozotocin[2]
-
Dosage:4.07 mg/kg (10 µmoL/kg).
-
Administration:Intraperitoneal injection; daily; for 12 weeks.
-
Result:Ameliorated diabetic myocardial fibrosis in T1D rats.
-
Animal Model:Four hundred and fifty Sprague-Dawley (SD) rats (half male and half female)[3].
-
Dosage:0.1, 1, or 5 mg/kg.
-
Administration:A continuous infusion.
-
Result:In all groups, MAP, LVSP, and ±dp/dtmax decreased significantly after shock.
Administration of 5 or 1 mg/kg Cal resulted in significantly increased values at 1 and 2 hr postadministration, compared to rats in the LR only group (or 0.01).
Rats treated with 1 mg/kg Cal demonstrated the greatest recovery.
LR infusion induced short-term and slightly increase of blood pressor in normal rats.
Cal (1 mg/kg) without LR infusion did not restore the decreased MAP after shock.
