New pyrimido[5,4-e]pyrrolo[1,2-c]pyrimidines: Synthesis, 2D-QSAR, anti-inflammatory, analgesic and ulcerogenicity studies

New pyrimido[5,4-e]pyrrolo[1,2-c]pyrimidines were synthesized. A series of ylidene carbohydrazides 14a-i, and hydrazonate 15, were obtained from the prepared 3-carbohydrazide derivative 13. Pyrazole derivatives 12, 16a,b, 18, 19, 20, were also prepared through different reactions. The anti-inflammatory and analgesic activities of all new compounds were evaluated and most of them exerted comparable activity to indomethacin and celecoxib. Ulcer indexes for the most active compounds were calculated and most of them showed less ulcerogenic effect than the reference drugs. The most potent anti-inflammatory compound 12 showed an IC50 of 6.00 mumol/kg and low ulcer index. COX-1/COX-2 activity ratio of compounds 12 and 16b showed almost equal inhibitory effect on both isoenzymes. 2D-QSAR studies revealed good predictive and statistically significant QSAR models.

ENANTIOSELECTVE REACTIONS CATALYZED BY CHIRAL TRIAZOLIUM SALTS

This invention provides a convenient method for converting imines and other electrophiles into heterocyclic ring systems. The process does not require the use of metallic reagents, and is catalyzed by an organic heterocyclic carbene catalyst. Accordingly, it produces the desired compounds without the concomitant production of a large volume of metallic waste. Chiral heterocyclic carbene catalysts of the invention and methods of using these catalysts produce chiral heterocycles in high enantiomeric and diastereomeric excess.

Diastereoselective synthesis of cyclic 1,3-aminoalcohols bearing CF3(CCl3)-groups

An aldol-type reaction of cyclic imines and cyclic lactims with carbonyl compounds activated by electron withdrawing trifluoromethyl or trichloromethyl groups proceeded without any catalyst under mild condition. beta-Hydroxymethyl substituted cyclic imines or imidates are formed as a result of the reaction. The reduction of the prepared imines leads stereoselectively to the cyclic 1,3-aminoalcohols. Application of methyl trifluoropyruvate in this transformation opens an opportunity for the synthesis of gamma-aminoacids derivatives which contain pyrrolidine moiety.

Pyrrolidino enaminones structural related to gyrase inhibitors: Synthesis, cyclization and pharmacological activity

The synthesis and stereochemical characteristics of pyrrolidino enaminones with structural analogy to quinolone antibacterial agents are reported. Retro-aldol reaction of the esters 7 is observed under all conditions of hydrolysis, the enzyme catalyzed reaction also does not yield the corresponding acids. In contrast to clinically used quinolones exemplary tests with monocyclic esters of type 7 and the tricyclic derivative 10 indicate low or no antibacterial activity. Additionally to the lack of the carboxylic acid function the enaminones 7 differ from quinolones in stereochemical demands and the electronic situation of the phenyl substituents of 10, respectively possibly preventing the formation of a co-operative tetrametric system between compounds and DNA bases.
