Background:
Hydrazide-hydrazones constitute an important class of compounds for new
drug development. In this study, a series of 39 new acylhydrazones (3-41), derived from (2S)-3-methyl-
2-[[(4-methylphenyl)sulfonyl]amino]butanoic acid hydrazide were synthesized with further aim to
achieve biologically active acylhydrazones carrying an amino acid side chain.
Methods:
Compounds 3-41 were synthesized by microwave-assisted method. All synthesized compounds
have been tested for their anti-HIV activity compound 21 was subjected to a new set of 2DNMR
analysis for the characterization of the isomers in solution and determination of its 3D structure.
Results:
The IC50 values for compounds 2-40 were found between >125-10.90 µg/ml against HIV-
1(IIIB) and HIV-2(ROD) strains in MT-4 cells. Compounds 3, 6, 10, 12, 23, 24, 27, 32, and 37 with
CC50 values between 10.90-14.50 µg/ml were selected to evaluate for their antileukemia activity. IC50
values for these mentioned compounds were found as >100μM on human chronic myelogenous leukemia,
K562 cell line.
Conclusion:
Some compounds with IC50 values between 10.90-14.50 μg/ml will be of benefit in the
development of novel leads.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
