Synthesis and evaluation of dual antiplatelet activity of bispidine derivatives of N-substituted pyroglutamic acids

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

Synthesis and identification of chiral aminomethylpiperidine carboxamides as inhibitor of collagen induced platelet activation

A series of chiral lactam carboxamides of aminomethylpiperidine were synthesized and investigated for the collagen induced in vitro anti-platelet efficacy and collagen plus epinephrine induced in vivo pulmonary thromboembolism. The compound 31a (30 μM/kg) displayed a remarkable antithrombotic efficacy (60% protection) which was sustained for more than 24 h and points to its excellent bioavailability. The compounds 31a (IC50 = 6.6 μM) and 32a (IC50 = 37 μM), as well as their racemic mixture 28i (IC50 = 16 μM) significantly inhibited collagen-induced human platelet aggregation in vitro. Compound 34c displayed dual mechanism of action against both collagen (IC50 = 3.3 μM) and U46619 (IC50 = 2.7 μM) induced platelet aggregation. The pharmacokinetic study of 31a indicated very faster absorption, prolonged and constant systemic exposure and thereby exhibiting better therapeutic response.

INHIBITORS OF FARNESYL-PROTEIN TRANSFERASE

The present invention comprises analogs of the CA1A2X motif of the protein Ras that is modified by farnesylation in vivo. These CA1A2X analogs inhibit the farnesyl-protein transferase and the farnesylation of certain proteins. Furthermore, these CA1A2X an

Protection by pyroglutamic acid and some of its newly synthesized derivatives against glutamate-induced seizures in mice

The protection by pyroglutamic acid (CAS 98-79-3) and derivatives Ia-i (injected i.p.) against glutamate- and NMDA (N-methyl-D-aspartate) (i.c.v.) induced seizures in mice has been studied in comparison with known antiepileptics and antagonists of excitatory aminoacids. The potency of pyroglutamic acid and some derivatives (Id,f,g,h) against glutamate-induced convulsions was similar to that shown by glutamic acid diethylester and by valproic acid. Interestingly, pyroglutamic acid did not affect NMDA-induced convulsions which were well antagonized by both 2-amino-5-phosphono valeric acid and by diazepam. Thus, pyroglutamic acid may represent the starting for synthesis of excitatory aminoacid antagonists acting at non NMDA receptors.
