Facile green approach towards the synthesis of some phenyl piperazine based dithiocarbamates as potent hemolytic and thrombolytic agents.

The facile and efficient protocol for the synthesis of N-phenyl piperazine based di-thio-carbamates has been reported under neat conditions. A library of novel piperazine based di-thio-carbamates (3a-h) in excellent yields has been prepared. Solvent free, catalyst free and easy work up conditions make this protocol an attractive synthetic protocol to achieve novel biologically active di-thio-carbamates. The synthesized molecules have been characterized by FT-IR, HNMR and CNMR spectroscopic techniques. The pharmacological aspects of these derivatives have been evaluated via hemolysis and thrombolysis. All the target molecules (3a-h) exhibit mild to medium potential as hemolytic and thrombolytic agents. Among the synthesized derivatives, compound 3c showed least cytotoxicity and better thrombolytic potential.
