Antimalarial agent 55

Antimalarial agent 55 is an orally potent inhibitor of PfA-M1 and PfA-M17 aminopeptidases from Plasmodium falciparum, with K_i 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 K_i 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.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
