Improvement of both plasmepsin inhibitory activity and antimalarial activity by 2-aminoethylamino substitution
摘要:
We attached 2-aminoethylamino groups to allophenylnorstatine-containing plasmepsin (Plm) inhibitors and investigated SAR of the methyl or ethyl substitutions on the amino groups. Unexpectedly, compounds 22 (KNI-10743) and 25 (KNI-10742) exhibited extremely potent Plm II inhibitory activities (K-i < 0.1 nM). Moreover, among our peptidomimetic Plm inhibitors, we identified the compounds with the highest antimalarial activity using a SYBR Green I-based fluorescence assay. (C) 2010 Elsevier Ltd.
