Isoflavone Dimers and Other Bioactive Constituents from the Figs of Ficus mucuso

Phytochemical investigation of the figs of Ficus mucuso led to the isolation of three new isoflavone dimer derivatives, mucusisoflavones A–C (1–3), together with 16 known compounds. Some of the isolates were tested in vitro for their inhibitory properties toward β-glucuronidase and Plasmodium falciparum enoyl-ACP reductase (PfENR) enzymes. Compound 1 (IC50 0.68 μM) showed inhibitory activity on β-glucuronidase enzyme, while 3 (IC50 7.69 μM) exhibited a weak inhibitory activity against P. falciparum enoyl-ACP reductase (PfENR).
