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.
本发明涉及3,7-二氮杂双环[3.3.1]壬烷羧酰胺及其制备方法。本发明还涉及具有抗血栓(抗血小板)活性的一般式(1)化合物。该发明还涉及将这些基团用作体外和体内介导的胶原受体抑制剂,抑制胶原诱导的血小板粘附和聚集。此外,该发明还涉及这类化合物通过双重机制表现出抗血小板功效,既抑制了胶原又抑制了U46619(血栓素受体激动剂)诱导的血小板聚集。一般式(1)中,其中,R'为;其中R选自烷基、酰基、对甲苯磺酰基、叔丁氧羰基、芳基烷基或取代芳基烷基;R''优选选自卤素、氰基、低烷基、芳基、取代芳基和对甲苯磺基;R1选自氢和低烷基;R2选自低烷基和芳基;R3选自叔丁氧羰基和苯甲氧羰基;n = 0,1。
