Retinoids are a class of compounds derived from vitamin A or synthetic analogs that modulate gene expression by binding to nuclear retinoic acid receptors (RARs) and retinoid X receptors (RXRs). They include natural retinoids such as retinol, retinal, and retinoic acid, as well as synthetic analogs such as tretinoin (all-trans retinoic acid), adapalene, isotretinoin, and tazarotene.
Mechanism of action involves binding to RARs and RXRs, which alters transcription of genes involved in cell
