A chemicals which can cause toxic effects when exposed to sunlight.
Substances found in many different plants, especially psoralea corylifolia (legume). They are used for skin diseases, especially vitiligo (disorder characterized by regions of otherwise normal skin of nonpigmented white patches of varied sizes) and as sunscreens. They interact with nucleic acids and are also used as research tools. Psoralens have a coumarin molecule with a furan ring.
A photosensitizing chemical administered orally or topically to increase the skin's reaction to light for a therapeutic effect.
photosensitizing chemical in plants used in the treatment of psoriasis.
A drug that can form chemical adducts with nucleic acids if exposed to UV light.
Any of a number of drugs and other substances containing chemicals that react with ultraviolet (UV) light to cause darkening of the skin.
A photosensitising drug used in combination with UVA to treat psoriasis (also known as PUVA therapy).
a chemical agent that stimulates pigment cells to produce more melanin when exposed to the sun. It is found in tan accelerators.
a substance C11 H6 O3 found in some plants capable of forming photoadducts with nucleic acids if irradiated with ultraviolet light (one application is photosensitization of mammalian skin, used in conjunction with ultraviolet light to treat psoriasis).
Psoralen (also called psoralene) is the parent compound in a family of natural products known as furocoumarins. It is structurally related to coumarin by the addition of a fused furan ring, and may be considered as a derivative of umbelliferone. Psoralen occurs naturally in the seeds of Psoralea corylifolia, as well as in the common Fig and West Indian satinwood.
