Formation of 3-pyrrolin-2-one or imidazolidine derivatives by slow dimerization of N-substituted aziridine-2-carboxylates

Prolonged storage (45-60 days) of N-methyl- or N-cyclopropylaziridine-2-carboxylates leads to their dimerization through the N-C(3) bond cleavage to form 1,3-disubstituted 2-methylimidazolidine-2,4-dicarboxylates in high yields. Prolonged storage of 1-benzylaziridine-2-carboxylate (like the reactions of alkyl pyruvates with primary amines) results in cyclocondensation to yield 3-pyrrolin-2-one derivative.

Characterization of Dielectric Relaxation Process by Impedance Spectroscopy for Polymers: Nitrile Butadiene Rubber and Ethylene Propylene Diene Monomer

We invented a dispersion analysis program that analyzes the relaxation processes from dielectric permittivity based on a combination of the Havriliak-Negami and conductivity contribution functions. By applying the created program to polymers such as nitrile butadiene rubber (NBR) and ethylene propylene diene monomer (EPDM), several relaxation processes were characterized: an alpha process due to segmental motions of the C-C bond, an alpha ‘ process attributed to fluctuations in the end-to-end dipole vector of the polymer chain, the conduction contribution by the filler observed above room temperature, and secondary relaxation processes beta and gamma of motion for the side group in NBR. In the EPDM specimen, the beta process associated with the rotational motion of the side groups, the alpha process associated with the relaxation of local segmental motion, and the alpha beta process associated with the origin of the beta process at high temperatures above 305 K were observed. The Maxwell-Wagner-Sillars effect and conduction contribution were also presented. The molecular chains responsible for the relaxation processes were assigned by building molecular models of the two polymers. The temperature dependence of the relaxation strength and the shape parameters that characterize the process were investigated. From the temperature-dependent relaxation analysis, the merged alpha beta process, activation energy, and glass transition temperature were determined and compared.

Synthesis, molecular modeling and biological evaluations of novel pyrrolidine derivatives as potential cyclooxygenase-2 (COX-2) inhibitors

Toward the development of selective cyclooxygenase-2 inhibitors, a series of pyrrolidine derivatives is described. All the compounds containing sulfonamide, ester, nitrile, acid, amide and urea functionalities were computationally screened, and binding affinity scores for all synthesized compounds with cyclooxygenase-1 and cyclooxygenase -2 were compared. The computational observations showed three top-ranked compounds (8b, 8d and 10a) having selectively more affinity for cyclooxygenase -2. These were selected for pharmacological evaluation using carrageenan-induced rat paw edema model. Compound 8b showed maximum activity (54.83%) which was closer to standard drug indometacin (57.48%). The safety parameter of the potent compound (8b) was assessed using aspirin induced gastric ulceration animal model. [GRAPHIC].
