Abstract
A glycoside derived from hypocrellin B was designed and synthesized us ing an improved Konigs-Knorr reaction. The water-solubility and red ab sorption of the resulting product was enhanced significantly over hypo crellin B. Electron spin resonance (ESR) measurements indicated that t his glycoside remained photodynamically active in terms of Type I and Type II mechanisms. (C) 1998 Elsevier Science Ltd.
