tailieunhanh - Characterization and bio activity evaluation of two new acetohydrazide synthesized from curcumin and monocarbonyl curcumin analog

ince the acetohydrazides are important starting materials in organic synthesis, the complicated structures of the acetohydrazides were characterized carefully with modern physical methods including IR, NMR and MS spectra. Almost all carbons and protons of A3 and B3 were assigned. Bio-activity testes showed that both were inactive on KB cell line and against bacteria. |
