説明
Anthralin is an anthrone inhibitor of keratinocyte proliferation and a modulator of differentiation. It increases apoptosis and inhibits proliferation of normal human keratinocytes (NHKs) when used at a concentration of 2.5 μM. It also decreases the mitochondrial membrane potential, increases cytochrome
c release, and induces perinuclear mitochondrial clustering in NHKs when used at a concentration of 5 μM. Anthralin (0.25 μM) decreases the expression of β-defensin-2 and S100 calcium-binding protein A9 (S100A9) and increases the expression of IL-6 and IL-8 in IL-17A- and IL-22-stimulated NHKs. It also inhibits leukotriene B
4 (LTB
4; ) production, stimulated by the calcium ionophore A23187 , from human neutrophils (IC
50 = 7 μM). Topical anthralin (0.1%) induces hair regrowth in a Dundee experimental bald rat (DEBR) model of alopecia areata.
