Same data, different structures: diastereoisomers with substantially identical NMR data from nature.

Fusarins G1/G2 (1/2) and G3/G4 (3/4), two sets of interesting examples of diastereoisomers with substantially identical NMR data, were discovered from natural products. The reason was discussed and the generally applicable determinant conditions were proposed. The minimum interval for stereoclusters to be entirely segregated was also discussed.

New isocoumarins from a cold-adapted fungal strain mucor sp. and their developmental toxicity to zebrafish embryos.

Three new isocoumarin derivatives, mucorisocoumarins A-C (1-3, resp.), together with seven known compounds, 4-10, were isolated from the cold-adapted fungal strain Mucor sp. (No.

Three new glucosides from a cold-adapted fungal strain Mucor sp.

Two new naphthaline glucosides, 2-hydroxy-3-methoxy-8-methyl-1-O-β-d-glucopyranosylnaphthaline (1) and 1-hydroxy-3-methoxy-8-methyl-2-O-β-d-glucopyranosylnaphthaline (2), together with one new isocoumarin glucoside, 3-(3,3-dichloro-2-hydroxylpropyl)-6-methoxy-8-O-β-d-glucopyranosyl-1H-isochromen-1-one (3), were isolated from a cold-adapted fungal strain Mucor sp. (No. XJ07027-5).
