Abstract
As a follow-up to earlier reported works on the phytochemical study of some isolated bioactive
compounds from the root and bark of Entandrophragma congoënse as potent anti-plasmodium
drugs (Happi et. al.2005), some of the isolated compounds were tested in vitro for antiplasmodial
and cytotoxicity but no insight was given into the binding affinities of these compounds, the ADMET
(Absorption, Distribution, Metabolism, Excretion and Toxicity), drug-likeness studies as well as
molecular dynamics simulation of some of the isolates. Hence, a total of 21 compounds including 19
isolates and 2 standard drugs were computationally studied for antimalarial activity against the
target receptor with Protein Data Bank code (PDB code: 5TBO), but only 4 of the isolated
compounds (L1, L2, L4 and L15) showed promise potent hits against Plasmodium. The results of
molecular docking, ADMET studies and molecular dynamics simulations reveal that compound L15,
when isolated, can alone, or together with other qualified compounds such as L1, L2 and L4 provide
a better inhibition rating compared to Chloroquine® (L21) the FDA-approved drug for the treatment
of malaria.
