  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.

  日期：2017.4.18

  A new protocol for the catalytic cyclopropanation of α,β-unsaturated carbonyl compounds with diiodomethane by means of photoredox catalysis has been successfully developed. The transformation is characterized by its mild conditions, functional group compatibility, and excellent selectivity profile.
