Mibefradil dihydrochloride is an blocker of calcium channel with moderate selectivity for T-type Ca2+ channels (T-type and L-type currents with IC50s of 2.7 μM and 18.6 μM, respectively). Mibefradil dihydrochloride inhibits reversibly the T- and L-type currents with IC50 values of 2.7 and 18.6 μM, respectively.

1,2,4-Trihydroxybenzene (Benzene-1,2,4-triol) is a by-product of coffee bean roasting and is found in mouse, arabica coffee.1,2,4-Trihydroxybenzene is a benzotriol that increases Ca2+ concentration in rat thymic lymphocytes.
