Synthesis and photochemotherapeutic activity of thiopyrano[2,3-e]indol-2-ones
摘要:
A series of derivatives of the new ring system thiopyrano[2,3-e]indol-2-one was prepared with the aim of obtaining new photochemotherapeutic drugs. Biological screenings were performed on this new class of photoactivable drugs and a strong anti-proliferative effect was observed upon irradiation with UVA light. The compound bearing a methyl substituent at the pyrrole nitrogen resulted as the most interesting showing IC50 in the nanomolar range. (c) 2005 Elsevier Ltd. All rights reserved.
