  • Adapalene Gel

Biochem/physiol Actions

Retinoic acid analogue that is a RARβ and RARγ agonist (AC50 values are 2.2, 9.3, 22 and > 1000 nM for RARβ, RARγ, RARα and RXRα receptors respectively). Inhibits proliferation and induces apoptosis in colorectal cancer cells in vitro. Displays comedolytic activity. Its unique pharmacological properties make it superior to other retinoids for the treatment of acne.

Darier's disease is an autosomal dominant disorder of keratinization that can produce unique clinical manifestations. Oral and topical retinoid products have been the mainstay therapy for this population, but local as well as systemic side effects often limit their effectiveness.

Adapalene, a naphthoic acid derivative with retinoid-like activity, is used for the topical treatment of mild to moderate acne vulgaris. It binds to retinoic acid receptors found predominantly in the terminal differentiation zone of epidermis and is more active than

Adapalene, a naphthoic-acid derivative, possesses some of the biological activities of tretinoin but has distinct physicochemical properties and binding properties for selective affinity for retinoic acid receptors. As such, adapalene is less likely to be associated with certain local tolerability

Extensive modification of the retinoic acid molecular skeleton has resulted in the development of adapalene, a more stable, less irritating compound with receptor selectivity. Adapalene selectively targets nuclear retinoic acid receptors found primarily in the epidermis. Pharmacologic and preclinical studies
