Accelerated thermal, hydrolytic, and photochemical degradations of alprazolam were performed under several reaction conditions. The stress studies revealed the photolability of the drug as the most adverse stability factor; the main photodegradation products were isolated and properly characterized
A new pyrrololactam, the debromoaxinohydantoin (2b), has been discovered in Monanchora sponge along with the known pyrrologuanidines la, lb, and the pyrrololactam 2a. The structure of 2b was confirmed by extensive NMR studies and MS data.
The major class of mycotoxins produced by Fusarium moulds are trichothecenes, a large group of sesquiterpenes sharing the same basic chemical structure, a 12,13-epoxytrichothec-9-ene ring system. Their toxic effects range from causing diarrhoea, vomiting and gastro-intestinal inflammation to noncomp
