Dibenz[b,c]oxepinalkanoic acids as nonsteroidal antiinflammatory agents. 4. Synthesis and evaluation of 4-(4,10-dihydro-10-oxothieno[3,2-c][1]benzoxepin-8-yl)butanol and -butyric acid and related derivatives

[3,2-c][1]-benzoxepin-8-yl) butanol (4b) and -butyric acid (5a) and a series of related derivatives. All compounds were evaluated for potential analgesic activity in the phenylquinone-induced writhing (PQW) assay, for antiinflammatory activity in the carrageenan-induced paw edema (CPE) model and, where warranted, for gastric irritation (GI) liability. Of the compounds investigated, 4b (HP 573) displays
先前已报道了4,10-二氢-10-氧杂噻吩并[3,2-c] [1]苯并二恶英-8-乙酸(6)作为有效的消炎镇痛药,与吲哚美辛相比,具有令人印象深刻的治疗率。为了找到与6相比可能显示出更好的治疗比率和/或增强的抗炎/镇痛特性的化合物,我们合成了4-(4,10-dihydro-10-oxothieno [3,2-c] [1 ]-苯并二氧杂-8-基)丁醇(4b)和-丁酸(5a)及一系列相关衍生物。在苯醌诱导的扭体(PQW)分析中评估了所有化合物的潜在止痛活性,在角叉菜胶引起的爪水肿(CPE)模型中评估了抗炎活性,并在必要时评估了胃刺激性(GI)的耐受性。在研究的化合物中,4b(HP 573)在PQW中表现出中等的镇痛样活性,在CPE中的效力约为消炎痛的一半,而在CPE中则为抗炎剂的效力的六倍,其特征是极低的诱发GI的倾向,如治疗比率的比较所反映(GI ED50 / CPE ED50:4b大于46,6
