Abstract

Two new compounds, geranylpyrrol A (1) and piericidin F (2), were isolated from a reedsmycins nonproducing mutant strain of Streptomyces sp. CHQ-64. Their structures, including absolute configurations, were elucidated by extensive NMR, MS, NOESY, and ECD analyses. Geranylpyrrol A (1) is an unusual naturally occurring 2,3,4-trisubstituted pyrrole, and piericidin F (2) showed cytotoxicity against HeLa, NB4, A549, and H1975 cell lines with IC50 values of 0.003, 0.037, 0.56, and 0.49 μM, respectively.
