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.

Among matrix metalloproteinases (MMPs), gelatinases MMP-2 (gelatinase A) and MMP-9 (gelatinase B) play a key role in a number of physiological processes such as tissue repair and fibrosis. Many evidences point out their involvement in a series of patholog
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.

N-Benzyl-4,5-dichloro-1H-pyrrole-2-carboxylic esters 6 are formed from N-benzyl-5-oxoproline esters 5 and PCl5 via differently chlorinated intermediates.The N-benzhydryl- L-3 and N-acyl-5-oxoproline esters L-4, on the other hand, suffer cleavage of the N-substituent in the course of this reaction sequence to give L-4,4,5-trichloro-3,4-dihydro-2H-pyrrole-2-carboxylic esters 18, which are dehydrohalogenated in the presence of base, yielding 4,5-dichloro-1H-pyrrole-2-carboxylic esters 20.These reactions provide the best access to 4,5-dichloro-1H-pyrrole-2-carboxylic acid derivatives which, in turn, can serve as precursors in the synthesis of pyoluteorin type compounds.
