Furocoumarins are an important group of natural bioregulators. These compounds are mainly derivatives of the widely distributed natural linear furocoumarin psoralen. Its angular isomers, angelicin or allopsoralen and their derivatives are not nearly as common. Natural furocoumarins and their synthetic analogs possess a variety of physiological activities, depending on the chemical structure. In particular, they increase the sensitivity of humans and animals to sunlight by ...
