Synthesis and biological activity studies of some new hybrid compounds derived from antipyrine

N-Benzyl-N'-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)urea (1) was obtained from antipyrine. The reaction of 1 with ethyl bromoacetate produced the 1,3-oxazole derivative 2. Compounds 5a-c were obtained from antipyrine by three steps via in

Antipyrine congeners as antidepressant agents

1-(N-Antipyrinylglycyl)-3-arylideneamino)-2-thiobarbituric acids (III) were synthesized from 1-arylidene-4-(N-antipyrinyl glycyl)-3-thiosemicarbazones (II). Compounds II in turn were prepared from 4-amino antipyrine. Compounds III were finally converted into 1-(N-antipyrinylglycyl)-3-[(3'-chloro-4-aryl) azitidinyl]-2-thiobarbituric acids (IV). 4-Aminoantipyrine was also treated with different N-protected amino acids in the presence of N,N'-dicyclohexylcarbodiimide to yield N-(antipyrinylcarbamoyl) substituted alkyl benzamides (V); their debenzoylation yielded 2-(amino-N-antipyrinyl) substituted acetamides (VI). The compounds were screened for their antidepressant activity. Compounds IIId, Va and Vb exhibited activity better than imipramine with less toxicity (ALD50 > 1000 mg/kg).
