Mc. Zafrapolo et al., POLYALTHIDIN - NEW PRENYLATED BENZOPYRAN INHIBITOR OF THE MAMMALIAN MITOCHONDRIAL RESPIRATORY-CHAIN, Journal of natural products, 59(10), 1996, pp. 913-916
Polyalthidin (3), a new benzopyran derivative, was isolated from the s
tem bark of Polyalthia cerasoides. Its structure was established on th
e basis of chemical and spectral evidence. Polyalthidin has showed pot
ent biological activity as an inhibitor of the mammalian mitochondrial
respiratory chain.
