Synthesis and photo-induced biological properties of methylated or methoxylated homopsoralen derivatives

Faulques,Rene,Royer,Averbeck

, p. 365 - 370 (2007/10/02)

We describe here the synthesis of pyranocoumarin derivatives methylated or methoxylated at the 10 position. These derivatives are intracyclic homologues of psoralen and 3-carbethoxy homopsoralen. The photo-induced biological effects of these methylated de
