Abstract
A novel class of molecules with structure N-[3-(heteroaryl)propyl]-6-methoxynaphthalene-2-carboxamides 8-13 were synthesized by condensing 6-methoxy-2-naphthoyl chloride 1 with 3-(heteroaryl)propyl amines 2-7. Compounds 8-12 were evaluated in vitro, in P388 murine lymphocytic leukemia cell line (P388) using SRB assay for cytotoxicity and in adriamycin resistant P388 murine lymphocytic leukemia cell line (P388/ADR) using MTT assay for resistant reversal activity. Compounds 8-12 were non-toxic at lower dose of 20 microg/ml, and effectively reversed adriamycin resistance. However, at higher doses (40, 80 microg/ml) they showed significant cytotxicity and hence reversal potency was not determined at these concentrations.
