J Gen Appl Microbiol. 2021 Jul 31;67(3):114-117. doi: 10.2323/jgam.2020.08.004. Epub 2021 Apr 2.

Abstract

Two Indonesian fungi Aspergillus assiutensis BioMCC-f.T.7495 and Penicillium pedernalense BioMCC-f.T.5350 along with a Japanese fungus Hypomyces pseudocorticiicola FKI-9008 have been found to produce gentisyl alcohol (1), which inhibits Plasmodium falciparum dihydroorotate dehydrogenase (PfDHODH) with an IC50 value of 3.4 μM. Another Indonesian fungus, Penicillium citrinum BioMCC-f.T.6730, produced an analog of 1, homogentisic acid (4), which also inhibits PfDHODH with an IC50 value of 47.6 μM.

Keywords: Plasmodium falciparum; dihydroorotate dehydrogenase; inhibitor; malaria.
