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. General formula (1) Wherein, R' is; wherein R is selected from alkyl, acyl, tosyl, tert-butyloxycarbonyl, araalkyl or substituted araalkyl groups; R'' is selected preferably from halogen, cyano, lower alkyl, aryl, substituted aryl, and tosyl groups; R1 is selected from hydrogen and lower alkyl groups; R2 is selected from lower alkyl and aryl groups; R3 is selected from tert-butyloxycarbonyl and bezyloxycarbonyl groups; n = 0,1.

N-aralkylpyroglutamides of substituted bispidine were prepared and evaluated for their ability to inhibit collagen induced platelet aggregation, both in vivo and in vitro. Some compounds showed high anti-platelet efficacy (in vitro) of which six inhibited both collagen as well as U46619 induced platelet aggregation with concentration dependent anti-platelet efficacy through dual mechanism. In particular
