Synthesis and anthelmintic activity of benzopyrano[2,3-c]pyrazol-4(2H)-one derivatives
Original language description
A series of benzopyrano[2,3-c]pyrazol-4(2H)-one derivatives were synthesized from readily available 1-phenyl- and 1-methyl-1H-pyrazol-3-ols by sequentially employing O-acylation, Fries rearrangement and potassium carbonate-induced cyclization. The anthelmintic properties of the obtained compounds were investigated in vivo in a model nematode, Caenorhabditis elegans. Five compounds, namely 2-phenyl[1]benzopyrano[2,3-c]pyrazol-4(2H)-one 33 and its 7-fluoro, 7-chloro-, 7-bromo- and 8-fluoro-analogues, 36, 38, 40 and 43, respectively, altered the development of C. elegans. While the activities of 33 and 43 were rather modest, compounds 36, 38 and 40 inhibited the growth of the worms at concentrations of approximately 1-3 µM. At these concentrations, the compounds did not kill the worms, but they strongly inhibited their development, with the majority of larvae never progressing past the L1 stage. Moreover, testing in non-cancer human cell lines showed that, with exception of 7-bromo derivative 40, the active compounds have favourable toxicity profiles.
