Pro-Apoptotic and Immunostimulatory Tetrahydroxanthone Dimers from the Endophytic Fungus Phomopsis longicolla
...Published in The Journal of Organic Chemistry
Four tetrahydroxanthone dimers (1-4) and four biogenetically related monomers (5-8), including the new derivatives (4-6), were isolated from the endophyte Phomopsis longicolla. The absolute configurations of 2-4 were established for the first time by TDDFT ECD calculations and that of phomoxanthone A (1) was revised by X-ray crystallography. Phomox...
