8-Geranyloxypsoralen is a natural furanocoumarin, which is a secondary metabolite typically derived from plants, particularly those in the Rutaceae family. Its source lies predominantly in certain fruits and herbs, where it functions as a natural defense compound. The mode of action of 8-Geranyloxypsoralen involves its interaction with DNA upon activation by ultraviolet (UV) light. It can form covalent bonds with pyrimidine bases, primarily thymine, in the DNA strands. This interaction leads to the formation of monoadducts, which can subsequently result in crosslinking upon further exposure to UV-A, disrupting DNA replication and transcription processes. 8-Geranyloxypsoralen finds its applications in phototherapy and is often studied for its potential therapeutic uses in skin diseases, such as psoriasis, and vitiligo. Its ability to modulate biological responses under light exposure makes it a candidate for further exploration in understanding light-mediated cellular processes. Furthermore, it provides insights into plant defense mechanisms and the complex interactions between plant-derived compounds and biological systems under environmental stressors.
