ABSTRACT The microbiological transformation of ent-beyer-15-en-18-ol 1 and ent-beyer-15-en-19-ol 2, using Mucor plumbeus, resulted in hydroxylated products. After nine days of incubation, 15?,16?-epoxide-ent-beyeran-7b,18-diol ...

Seventeen compounds (2-18) synthetized from the diterpenoid ent-beyer-15-en-18-ol (1) isolated from aerial part of Baccharis tola were tested for their gastroprotective activity on the model of HCl/EtOH-induced gastric ...

The phytochemical analysis of the EtOAc extract of the flowers from Perymenium buphthalmoides afforded oleanyl palmitates (10) and oleanolic acid (11) as major constituents. As part of the chemical characterization, the ...

Colistin is a last-resort antibiotic for the treatment of multidrug resistant Gram-negative bacterial infections. Recently, a natural ent-beyerene diterpene was identified as a promising inhibitor of the enzyme responsible ...

Novel diterpenoids were isolated from the extracts of Fabiana densa var. ramulosa and found to display a selective activity against Gram-positive bacterial strains with negligible cytotoxicity toward human keratinocytes. ...
