  A new benzoangelicin with strong photobiological activity

  摘要：

  Benzoangelicins 4-6 were synthesized in good yields from 7-hydroxy-5-methoxy-4-methylcoumarin (1). In the absence of UVA radiation, compounds 5 and 6 were only weakly active against HL60 and HeLa tumour cells; in its presence, compound 6 was 10 times more active than the reference compound 8-methoxypsoralen. None of 4-6 exhibited cutaneous phototoxicity. (C) 2000 Elsevier Science Ltd. All rights reserved.
