Anthralin is an anthrone inhibitor of keratinocyte proliferation and a modulator of differentiation.1 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.2 Anthralin (0.25 μM) decreases the expression of β-defensin-2 (Item No. 24577) 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.1 It also inhibits leukotriene B4 (LTB4; Item No. 20110) production, stimulated by the calcium ionophore A23187 (Item No. 11016), from human neutrophils (IC50 = 7 μM).3 Topical anthralin (0.1%) induces hair regrowth in a Dundee experimental bald rat (DEBR) model of alopecia areata.4 | [Chemical Properties]
Yellow Crystalline Solid | [Uses]
Antipsoriatic | [Uses]
Dithranol, a potential anti-psoriasis medication, may be used to study its safety, efficacy, metabolism and pharmacological profile. Dithranol may be used to study is physicochemical properties, as a reference compound and to develop effective drug delivery vehicles. Dithranol may be used as a matrix for matrix assisted laser desorption/ionization imaging on a Fourier transform ion cyclotron resonance mass spectrometer. | [Definition]
ChEBI: An anthracene compound derived by the substitution of -OH groups for hydrogen at C-1 and C-8, and with an oxo group at C-9. | [Indications]
Anthralin (Anthra-Derm) is a potent reducing agent
whose mechanism of action is unknown. It is approved
for the treatment of psoriasis and also may be helpful in
alopecia areata. The major toxicities are discoloration
of skin, hair, and nails and irritant dermatitis. | [Brand name]
Anthra-Derm (Dermik); DrithoCreme
(Dermik); Drithoscalp (Dermik); Lasan (Stiefel). | [Hazard]
Very irritating. Do not use on scalp or near eyes. | [Side effects]
Anthralin's side effects include pruritus, erythema, scaling,
folliculitis, and lymphadenopathy. Staining of skin and clothes can also be an issue. |
