A liquid chromatography-tandem mass spectrometric (LC-MS/MS) method following chemical derivatization with 3-nitrophtalic anhydride was developed for the simultaneous determination of farnesol and geranylgeraniol in rat liver and testis. One analogue compound of the analytes, n-pentadecanol, was used as an internal

New pre-column derivatizing reagents: phthalic anhydride, 3-nitrophthalic anhydride, diphenic anhydride, 1,8-naphthalic anhydride and diphenylmaleic anhydride have been developed for resolving chiral compounds having amine groups. Although all of these agents produce derivatives with high molar absorptivities, the later two also

Fourteen thalidomide analogs bearing two phthalimido units were prepared in high yields (83-94%) by condensation of different diamines with phthalic or 3-nitrophthalic anhydride. An in vitro investigation of the compounds as inhibitors of the TNF-alpha production was performed. The inhibition
