A variety of basic N,N',N'',-trisubstitutedguanidines was prepared and tested for antiinflammatory activity. Compounds with a thiazolylguanidine moiety linked to the 4 position of the 2-methylquinoline ring exhibited fairly high antiinflammatory activity. Optimal activity was associated with the presence of N-cycloalkyl substituents on N''-4-(2-methylquinolyl)-N'-2-thiazolylguanidine. Pharmacological
The utility of diazinyl substituted carbodiimides (1a-c) for the synthesis of novel guanidines (2), isothioureas (3), and isoureas (4) is shown. Attempts to determine the stereochemistry of the target compounds using NOE difference spectroscopy or X-ray analysis, respectively, are described.
