Pyrazole-pyrazoline as promising novel antimalarial agents: A mechanistic study
摘要:
A series of pyrazole-pyrazoline substituted with benzenesulfonamide were synthesized and evaluated for their antimalarial activity in vitro and in vivo. The compounds were active against both chloroquine (CQ) sensitive (3D7) and CQ resistant (RKL-9) strains of Plasmodium falciparum. Seven compounds (7e, 7i, 7j, 7l, 7m, 7o and 7p) exhibiting EC50 less than 2 mu M. A mechanistic study of compound 7o revealed that these compound act through the inhibition of beta-hematin. The study indicated that these compounds can serve as lead compounds for further development of potent antimalarial drugs. (C) 2018 Elsevier Masson SAS. All rights reserved.

A new series of pyrazolylpyrazolines (5a–k) was synthesized by the reaction of appropriate chalcones (3a–k) with 4-hydrazinobenzenesulfonamide hydrochloride (4) in ethanol. All the newly synthesized target compounds (5a–k) were screened for their anti-inflammatory activity using carrageenan-induced rat paw edema assay. Compounds 5g and 5j showed pronounced anti-inflammatory activity comparable to the
