Abstract
SNF4435C and D are new immunosuppressants isolated from the culture broth of a strain
of Streptomyces spectabilis. Their molecular formulas were determined as C28H31NO6
based on the HRFAB-MS analyses. The structures of SNF4435C and D were elucidated to
be novel nitrophenyl pyrones having an intriguing tricyclic ring system and diastereoisomers
of each other by spectroscopic analyses including various NMR measurements.
