Antimalarial agent 55 is an orally potent inhibitor of PfA-M1 and PfA-M17 aminopeptidases from Plasmodium falciparum, with Ki values of 27 nM and 81 nM, respectively. Antimalarial agent 55 exhibits potent nanomolar activity against homologous enzymes from Plasmodium vivax and Plasmodium berghei, with Ki values of 2 nM, 4 nM, 190 nM and 18 nM for Pv-M1, Pb-M1, Pv-M17 and Pb-M17, respectively. Antimalarial agent 55 possesses significant antiplasmodial activity, as well as cross-species inhibitory capacity and broad-spectrum activity that is unaffected by existing drug resistance mechanisms. Antimalarial agent 55 can be used in malaria research.

Description

Antimalarial agent 55 is an orally potent inhibitor of PfA-M1 and PfA-M17 aminopeptidases from Plasmodium falciparum, with Ki values of 27 nM and 81 nM, respectively. Antimalarial agent 55 exhibits potent nanomolar activity against homologous enzymes from Plasmodium vivax and Plasmodium berghei, with Ki values of 2 nM, 4 nM, 190 nM and 18 nM for Pv-M1, Pb-M1, Pv-M17 and Pb-M17, respectively. Antimalarial agent 55 possesses significant antiplasmodial activity, as well as cross-species inhibitory capacity and broad-spectrum activity that is unaffected by existing drug resistance mechanisms. Antimalarial agent 55 can be used in malaria research[1].

In Vitro

Antimalarial agent 55 (Compound 3k) (72 h) exhibits in vitro killing activity against the Plasmodium falciparum strain Pf3D7, with an EC50 of 31 nM; it also shows potent activity against clinically isolated Plasmodium falciparum strains with different drug resistance mechanisms.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
