FNDR-20123 free base

FNDR-20123 free base is an orally active, safe and a first-in-class anti-malarial HDAC inhibitor with IC50s of 31 nM and 3 nM for Plasmodium and human HDAC, respectively. FNDR-20123 free base exerts anti-malarial activity against Plasmodium falciparum asexual stage (IC50=41 nM) and sexual blood stage (IC50=190 nM for male gametocytes). FNDR-20123 free base inhibits HDAC1, HDAC2, HDAC3, HDAC6, and HDAC8 (IC50=25, 29, 2, 11, and 282 nM, respectively) and inhibits Class III HDAC isoforms at nanomolar concentrations.
