Seimisochromenes A and B: two new dihydroisochromenes from the endophytic fungus, Seimatosporium sp.
Two new dihydroisochromenes, named seimisochromenes A and B (1 and 2), were isolated from an endophytic fungus, Seimatosporium sp. The structures of seimisochromenes A and B have been determined from 1D ((1)H and (13)C NMR spectra) and 2D (COSY, HMQC, HMBC, and NOESY) NMR experiments.
