Potent and selective inhibitor of the type 1 ryanodine receptor (RyR1)
RyR1-selective inhibitor 1 (6,7-(methylenedioxy)-1-octyl-4-quinolone-3-carboxylic acid) potently and selectively inhibits the type 1 ryanodine receptor (RyR1). It prevents and treats malignant hyperthermia and heat stroke in several mouse models. RyR1-selective inhibitor 1 decreases resting intracellular Ca2+, inhibits halothane- and isoflurane-induced Ca2+ release, and suppresses caffeine-induced contracture in skeletal muscle.

Mutations in the type 1 ryanodine receptor (RyR1), a Ca2+ release channel in skeletal muscle, hyperactivate the channel to cause malignant hyperthermia (MH) and are implicated in severe heat stroke. Dantrolene, the only approved drug for MH, has the disadvantages

Type-1 ryanodine receptor (RyR1) is a calcium-release channel localized on sarcoplasmic reticulum (SR) of the skeletal muscle, and mediates muscle contraction by releasing Ca2+ from the SR. Genetic mutations of RyR1 are associated with skeletal muscle diseases such as malignant
