The present invention relates to the 3,7-diazabicyclo[3.3.1]nonane carboxamides and process for preparation thereof. The present invention further relates to the compounds of general formula 1 possessing anti-thrombotic (anti-platelet) activities. The invention also relates to use of these moieties as inhibitors of collagen induced platelet adhesion and aggregation mediated through collagen receptors both in vitro and in vivo. Further, invention also relates these class of compounds exhibiting anti-platelet efficacy through dual mechanism inhibited both collagen as well as U46619 (thromboxane receptor agonist) induced platelet aggregation.
