Chemical modification of usnic acid: III.* Reaction of (+)-usnic acid with substituted phenylhydrazines
摘要:
Reactions of (+)-usnic acid with a number of substituted (halo, alkyl, alkoxy, nitro) phenylhydrazines led to the formation of the corresponding benzofuro[3,2-f]indazole derivatives or hydrazones at the acetyl group on C(2), depending on the initial hydrazine.

Usnic acid is a secondary metabolite abundantly found in lichens, for which promising cytotoxic and antitumor potential has been shown. However, knowledge concerning activities of its derivatives is limited. Herein, a series of usnic acidderivatives were synthesized and their antiproliferative potency against cancer cells of different origin was assessed. Some of the synthesized compounds were more
