Nigrosporanenes C and D, two new cyclohexene derivatives from the enphytic fungus Nigrospora oryzae S4

Two new cyclohexene derivatives, nigrosporanenes C and D (1 and 2), together with three known compounds (3-5), were isolated from the culture of an endophyte Nigrospora oryzae S4. Their structures were characterized by a combination of detailed spectroscopic analysis and comparison of their NMR data...

Description
Summary:Two new cyclohexene derivatives, nigrosporanenes C and D (1 and 2), together with three known compounds (3-5), were isolated from the culture of an endophyte Nigrospora oryzae S4. Their structures were characterized by a combination of detailed spectroscopic analysis and comparison of their NMR data with those reported in the literature. All compounds were tested for anti-phytopathogenic activity, however, none of them showed activity at a concentration of 20 μM.
