Two new tetracyclic triterpenoids from the endophytic fungus Hypoxylon sp. 6269. Issue 10 (3rd October 2018) - Liang, Han-Qiao
Abstract: Two new tetracyclic triterpenoids, integracide E (1 ) and isointegracide E (2 ), as well as three known secondary metabolites (i.e. integracide A (3 ), 2-deoxyintegracide A (4 ) and 2-deoxyintegracide B (5 )), were isolated from mycelium of the endophytic fungus Hypoxylon sp. 6269. Structures were determined by a combination of 1D and 2D NMR techniques and mass spectrometry. All of the compounds were tested for their anti-HIV-1 integrase activities. Abstract :
