Description

Minoxidil, a trichogenic compound that stimulates the hair follicle, is a pro-drug converted to its active form, minoxidil sulfate, by sulfotransferase enzymes in the outer root sheath of hair. Minoxidil sulfate is required for both the promotion of hair regrowth and the vasodilatory effects of minoxidil. Minoxidil sulfate is an activator of the ATP-sensitive K+ (KATP) channel. The opening of K+ channels is thought to be an important mechanism in the regulation of hair follicles.

The mechanism of smooth muscle relaxing effect of minoxidil sulfate (MxSO4) was investigated in isolated rabbit superior mesenteric artery. MxSO4 (5 X 10(-6) M) was found to effectively relax maximal norepinephrine (NE; at 5 X 10(-6) M) contraction, but failed to relax 80 mM K+-induced contraction. MxSO4-induced relaxation was endothelium independent. Tetraethylammonium (5-10 mM) pretreatment caused pronounced inhibition of MxSO4-induced relaxation. Pretreatment with ouabain (0.5-5 microM) also significantly inhibited MxSO4 relaxation.
