psoraleneid

Psoraleneid refers to a class of organic compounds, also known as furocoumarins. These compounds are characterized by a furan ring fused to a coumarin backbone. They are naturally occurring and found in plants, particularly in the Apiaceae (carrot) and Rutaceae (citrus) families. Psoraleneids are perhaps best known for their photosensitizing properties. When exposed to ultraviolet A (UVA) radiation, they can bind to DNA, leading to photoadducts and subsequent cellular damage. This photoactivity is the basis for their use in photochemotherapy. The most common psoraleneid used therapeutically is 8-methoxypsoralen, often administered orally or topically in conjunction with UVA light to treat skin conditions like psoriasis, eczema, and vitiligo. However, this photosensitivity also means that exposure to sunlight after treatment can cause severe sunburn or hyperpigmentation. Research into psoraleneids continues to explore their potential in other medical applications and their mechanisms of action.
