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

  摘要：

  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 mu mol/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.

  Novel series of bicyclic pyrrolo[1,2-cipyrimidines 3a-g, 5, 6a, b, and 7a, b, tricyclic pyrimido[5,4-elpyrrolo[1,2-c]pyrimidines 8a-c, 9a-g, 13a-c, 17,18a, b, 19, 20a,b and 21 and tetracyclic condensed pyrimidines 14, 22 and 23 were synthesized through different chemical reactions. Structures of all synthesized pyrimidine derivatives were supported by spectral and elemental analyses. Analgesic activity evaluation was carried out using acetic acid-induced writhing assay, and all compounds exerted comparable activity to indomethacin. The anti-inflammatory activity evaluation was performed using carrageenan-induced paw edema in rats, the potency of the bicyclic derivatives 3a-f and 7b revealed comparable activity to indomethacin without gastric ulceration. The tricyclic derivatives 13a and 20a exerted good activity, however, they induced gastric ulcers while 13b and 13c showed moderate activity without ulceration. In case of tetracyclic derivatives, compound 14 exhibited the highest potency and safety profile. (C) 2009 Elsevier Masson SAS. All rights reserved.
