Y. Mizushina et al., Lucidenic acid O and lactone, new terpene inhibitors of eukaryotic DNA polymerases from a basidiomycete, Ganoderma lucidum, BIO MED CH, 7(9), 1999, pp. 2047-2052
Terpenoids, 1, 2 and 3, which selectively inhibit eukaryotic DNA polymerase
activities, were isolated from the fruiting body of a basidiomycete, Ganod
erma lucidum, and their structures were determined by spectroscopic analyse
s. New terpenes, lucidenic acid O (1) and lucidenic lactone (2), prevented
not only the activities of calf DNA polymerase alpha and rat DNA polymerase
beta, but also these of human immunodeficiency virus type 1 reverse transc
riptase. Cerevisterol (3), which was reported to be a cytotoxic steroid, in
hibited only the activity of DNA polymerase alpha. Although these compounds
did not influence the activities of prokaryotic DNA polymerases and other
DNA metabolic enzymes such as T7 RNA polymerase and deoxyribonuclease I. (C
