PlanTo synthesize some novel 2-amino thiophenes with various substitutions at 2-amino position for anti-platelet aggregation activity.

PrefaceVarious substituted and condensed thiophenes are reported to possess a wide variety of biological and pharmacological activities such as antibacterial, antifungal, anti-inflammatory, anti-platelet aggregation activity, antipyretic, antitumor and so on. Thus a series of new thiophenes have synthesized with various substituents at 2-amino position and screened for anti-platelet aggregation activity.

MethodologyThe starting material (JMS-2) was prepared by the application of versatile Gewald reaction. It was then derivatized to various Schiff bases JMS-2(a-m) by reacting with various substituted aromatic aldehydes. The synthesized new compounds were characterized by MP, TLC, IR, NMR and Mass spectra and were screened for their In-vitro anti-platelet aggregation activity by GVR Born method using Heparin as the standard.

OutcomeCompound JMS-2a, JMS-2b, JMS-2d and JMS-2i showed good % inhibition and were found to be more significant.

Keywords2-amino thiophene, Gewald reaction, anti-platelet aggregation.
