Dantrolene can be used for the research of muscle spasticity, malignant hyperthermia, Huntington's disease and other neuroleptic malignant syndrome.

O-Desmethyl carvedilol-d5

O-Desmethyl carvedilol-d₅ (Desmethylcarvedilol-d₅) is deuterium labeled O-Desmethylcarvedilol. O-Desmethylcarvedilol (Desmethylcarvedilol) is an active metabolite of the non-selective β-adrenergic receptor (β-AR) antagonist Carvedilol (HY-B0006). O-Desmethylcarvedilol inhibits store-overload-induced calcium release in HEK293 cells expressing the ryanodine receptor 2 (RyR2) R4496C (RyR2 ^R4496C) mutation (IC₅₀ = 7.62 μM). O-Desmethylcarvedilol reduces increases in heart rate and prevents decreases in diastolic blood pressure induced by Isoproterenol (HY-B0468) in conscious rabbits (ED₅₀s = 32 and 5 μg/kg, respectively) .
