Abstract: Four new pyridine derivatives, monasnicotinates A–D (1–4) were isolated from the red yeast rice of Monascus pilosus BCRC 38093. Their structures were elucidated on the basis of physicochemical evidence, in-depth NMR spectroscopic analysis, and high-resolution mass spectrometry. Their inhibitory effects on NO production was also evaluated.
Keywords: Monascus pilosus BCRC 38093; pyridine derivatives; NO production
