  4-Functionalized 1,3-diarylpyrazoles bearing 6-aminosulfonylbenzothiazole moiety as potent inhibitors of carbonic anhydrase isoforms hCA I, II, IX and XII

  摘要：

  A series of 24 novel heterocyclic compounds-functionalized at position 4 with aldehyde (5a-5f), carboxylic acid (6a-6f), nitrile (7a-7f) and oxime (8a-8f) functional groups-bearing 6-aminosulfonybenzothiazole moiety at position 1 of pyrazole has been synthesized and investigated for the inhibition of four isoforms of the alpha-class carbonic anhydrases (CAs, EC 4.2.1.1), comprising hCAs I and II (cytosolic, ubiquitous isozymes) and hCAs IX and XII (transmembrane, tumor associated isozymes). Against the human isozyme hCA I, compounds 6a-6f showed medium-weak inhibitory potential with Ki values in the range of 157-690 nM with 6a showing better potential than the standard drug acetazolamide (AZA). Against hCA II, all the compounds showed excellent to moderate inhibition with Ki values of compounds 5a, 5d, 5f, 6a-6f, 8d and 8f lower than 12 nM (Ki of AZA). Against hCA IX, all the compounds showed moderate inhibition with the exception of 6e which showed nearly 9 fold a better profile compared to AZA, whereas against hCA XII, four compounds 6e, 7a, 7b and 7d showed Ki in the same order as that of AZA. Carboxylic acid 6e was found to be an excellent inhibitor of both hCA IX and XII, with Ki values of 2.8 nM and 5.5 nM, respectively. (C) 2014 Elsevier Ltd. All rights reserved.

  Heteroaromatic analogues of 1,5-diarylpyrazole class as anti-inflammatory agents

  摘要：

  A novel series of heteroaromatic analogues of known anti-inflammatory (AI) drug celecoxib replacing the benzenesulfonamide moiety with 6-sulfonamidobenzothiazol-2-yl moiety was synthesized. Regioselective synthesis of the target compounds 2a-i having 1,5-diaryl relationship was achieved by exploring reaction conditions. All the newly synthesized compounds (2a-i and 8) were screened for their in vivo AI activity using carrageenan-induced rat paw edema assay. Five compounds (2c-f and 2i) were found to possess good AI activity (a parts per thousand yen60% inhibition), 3 h after the carrageenan injection when compared to that of standard drug indomethacin (78%), whereas the remaining four compounds (2a-b and 2g-h) with 1,5-diaryl relationship have shown moderate activity with 49-56% inhibition after 3 h. However, pyrazole 8 having 1,3-diaryl relationship failed to show appreciable AI activity.

  aims at the synthesis of pyrazolines bearing benzothiazole and their evaluation as anti-inflammatory agents. The synthesized compounds were evaluated for their anti-inflammatory potential using carrageenan induced paw edema model. Two compounds 5a and 5d alleviated inflammation more than the standard drug celecoxib. Eight compounds 5b, 5c, 5e, 5g, 5h, 6b, 6e and 6f showed anti-inflammatory activity comparable

  本研究旨在合成带有苯并噻唑的吡唑啉及其作为抗炎药的评价。使用角叉菜胶诱导的爪水肿模型评价合成的化合物的抗炎潜力。两种化合物5a和5d比标准药物塞来昔布更能减轻炎症。八个化合物5b，5c，5e，5g，5h，6b，6e和6f显示出与塞来昔布相当的抗炎活性。为了理解作用方式，进行了COX-2酶测定和TNF-α测定。评估所有活性化合物的细胞毒性。对未发现有细胞毒性的活性化合物进行了致溃疡风险评估。在十种活性化合物中，最终发现两种化合物（5d和6f）是最有效的抗炎药，可抑制COX-2酶活性和TNF-α的产生，而不会产生细胞毒性或致溃疡性。
