  Synthesis and antiinflammatory activity of some new 1,3,5-trisubstituted pyrazolines bearing benzene sulfonamide

  摘要：

  Nineteen new 2-pyrazoline bearing benzenesulfonamide derivatives were synthesized by condensing chalcones with 4-hydrazinonbenzenesulfonamide hydrochloride. Their chemical structures were proved by means of IR, H-1 NMR, C-13 NMR, mass spectroscopic and elemental analyses data. These compounds were tested at dose of 20 mg/kg for their anti-inflammatory activity in carrageenan-induced rat paw edema model and volume of paw edema was measured at 0, 3 and 5 h. Two compounds 3k and 3l were found to be more active than celecoxib throughout the study (at 3 and 5 h). While two other compounds 3m and 3n showed more potent activity than celecoxib at 5 h. They are devoid of ulcerogenic potential when administered orally at a dose of 60 mg/kg. Compounds (3k-m) showed COX-1 and COX-2 inhibitory activity at 0.05 mu M. (C) 2008 Elsevier Ltd.

  The most common mutation of CFTR, affecting approximately 90% of CF patients, is a deletion of phenylalanine at position 508 (F508del, ΔF508). Misfolding of ΔF508-CFTR impairs both its trafficking to the plasma membrane and its chloride channel activity. To identify small molecules that can restore channel activity of ΔF508-CFTR, we synthesized and evaluated eighteen novel hydroxypyrazoline analogues as CFTR potentiators. To elucidate potentiation activities of hydroxypyrazolines for ΔF508-CFTR, CFTR activity was measured using a halide-sensitive YFP assay, Ussing chamber assay and patch-clamp technique. Compounds 7p, 7q and 7r exhibited excellent potentiation with EC50 value <10 μM. Among the compounds, 7q (a novel CFTR potentiator, CP7q) showed the highest potentiation activity with EC50 values of 0.88 ± 0.11 and 4.45 ± 0.31 μM for wild-type and ΔF508-CFTR, respectively. In addition, CP7q significantly potentiated chloride conductance of G551D-CFTR, a CFTR gating mutant; its maximal potentiation activity was 1.9 fold higher than the well-known CFTR potentiator genistein. Combination treatment with CP7q and VX-809, a corrector of ΔF508-CFTR, significantly enhanced functional rescue of ΔF508-CFTR compared with VX-809 alone. CP7q did not alter the cytosolic cAMP level and showed no cytotoxicity at the concentration showing maximum efficacy. The hydroxypyrazolines may be potential development candidates for drug therapy of cystic fibrosis.

  CFTR 最常见的突变是 508 位苯丙氨酸缺失（F508del、ΔF508），约影响 90% 的 CF 患者。 ΔF508-CFTR 的错误折叠会损害其向质膜的运输及其氯通道活性。为了鉴定可以恢复 ΔF508-CFTR 通道活性的小分子，我们合成并评估了 18 种新型羟基吡唑啉类似物作为 CFTR 增强剂。为了阐明羟基吡唑啉对 ΔF508-CFTR 的增强活性，使用卤化物敏感的 YFP 测定、尤斯室测定和膜片钳技术测量 CFTR 活性。化合物 7p、7q 和 7r 表现出优异的增强作用，EC50 值 <10 μM。在这些化合物中，7q（一种新型 CFTR 增强剂，CP7q）显示出最高的增强活性，野生型和 ΔF508-CFTR 的 EC50 值分别为 0.88 ± 0.11 和 4.45 ± 0.31 μM。此外，CP7q 显着增强了 G551D-CFTR（一种 CFTR 门控突变体）的氯电导；其最大增强活性比著名的CFTR增强剂金雀异黄素高1.9倍。与单独使用 VX-809 相比，CP7q 和 VX-809（ΔF508-CFTR 的校正剂）的联合治疗显着增强了 ΔF508-CFTR 的功能挽救。 CP7q 不会改变胞质 cAMP 水平，并且在显示最大功效的浓度下没有表现出细胞毒性。羟基吡唑啉类药物可能是囊性纤维化药物治疗的潜在开发候选者。
