Design, Synthesis and Evaluation of the Biological Activities of Some New Carbohydrazide and Urea Derivatives.

Objectives: Urea and carbohydrazide derivatives are important compounds exhibiting cytotoxic activities. In this study, a series of new urea and carbohydrazide derivatives containing an pyridine ring were synthesized and evaluated for cytotoxic activity.

Materials And Methods: The proposed structures of the synthesized compounds were confirmed using elemental analysis, IR, and H-NMR spectroscopic techniques.
