-sis processes are not exempt from this trend, because many of these involve solvents or solutions difficult to recycle after reaction and in some cases are highly toxic . Chemical synthesis assisted by microwave is a powerful tool, which when applied to a wide range of chemical reactions allows for important contributions such as: reducing reaction times, high yields, avoiding collateral and substitute

Naturally occurring prenylated acylphloroglucinol derivatives are plant metabolites with diverse biological and pharmacological activities: Prenylation of acylphloroglucinols plays an important role in the formation of these intriguing natural products and is catalyzed in plants by membrane-bound enzymes. In this study, we demonstrate the prenylation of such compounds by a soluble fungal prenyltransferase AnaPT involved in the biosynthesis of prenylated indole alkaloids. The observed activities of AnaPT toward these substrates are Much higher than that of a microsomal fraction containing an overproduced prenyltransferase from the plant hop.
