Penitremones A–C, Penicillium metabolites containing an oxidised penitrem carbon skeleton giving insight into structure–tremorgenic relationships
A new group of microbial metabolites, designated penitremones A–C, have been characterised by mass spectrometry and 1H and 13C NMR spectroscopy as 10-keto, 11,33-dihydro-variants of the penitrem…

Two new indolic metabolites were isolated from Penicillium crustosum and separated from other penitrem mycotoxins by high-performance liquid chromatography and were shown to be tremorgenic in mice, although it has only one-third of the activity of penit Rem A.
