The mass spectrometric fragmentation of ( S, S) -N, N'-bis [ 1- (hydroxymethyl) alkyl] anthracene/naphthalene-1, 8-dicarboxamides was investigated with the aid of mass-analyzed ion kinetic energy spectrometry and...
The mass spectrometric fragmentation of 1-(benzyloxycarbonyl)amino-2-alkyl/cycloalkyl thioacetates has been studied with the aid of mass-analysed ion kinetic energy spectrometry under electron impact ionization. All...
Tumor necrosis factor is one of the important cell factors,which can regulate pro-imflammatory.On the basis of the known and efficient peptidomimetic inhibitors of tumor necrosis factor as the leading compounds,novel ...
The reactions of 2,3-dihydro-1,5-benzothiazepines with ethoxyearbonylcarbene undergo complex rearrangements to produce rlng-opening and ring contraction products. Previously it was presumed that the different products...
