    • N-substituted fused-heterocyclic carboxamide derivatives, for example, N-(2,2-diphenylethenyl)-3-hydroxythieno[3,2-b]thiophene-2-carboxamide can be prepared by ring closure between an appropriately substituted halo-thiophene ester, e.g., methyl 3-bromo-thiophene-2-carboxylate, and mercaptoacetamide followed by condensation with diphenylacetaldehyde. Alternatively, the ring closure can be carried out between an appropriately substituted mercaptothiophene ester, e.g., methyl 3-mercaptothiophene-2-carboxylate and a haloacetamide to afford the fused-heterocyclic intermediate, 3-hydroxythieno[3,2-b]thiophene-2-carboxamide. N-alkenylation of the intermediate will then lead to the final products.These compounds have been found to be effective inhibitors of both cyclooxygenase and lipoxygenase and thereby useful in the treatment of pain, fever, inflammation, arthritic conditions, eye inflammation caused by glaucoma or other eye diseases, asthma, allergic disorders, skin diseases, cardiovascular disorders, psoriasis, inflammatory bowel disease, or other prostaglandin and/or leukotriene mediated diseases.
    • N-取代的稠合杂环甲酰胺衍生物,例如N-(2,2-二苯基乙烯基)-3-羟基噻吩并[3,2-b]噻吩-2-甲酰胺可以通过在适当取代的卤代噻吩 酯,例如3-溴 - 噻吩-2-甲酸甲酯和巯基乙酰胺,随后与二苯基乙醛缩合。 或者,闭环可以在适当取代的巯基噻吩酯例如3-巯基噻吩-2-羧酸甲酯和卤代乙酰胺之间进行,得到稠合杂环中间体3-羟基噻吩并[3,2-b]噻吩-2 甲酰胺。 中间体的N-烯基化将导致最终产物。 已经发现这些化合物是环加氧酶和脂氧合酶的有效抑制剂,从而可用于治疗疼痛,发热,炎症,关节炎病症,由青光眼或其他眼睛疾病引起的眼睛炎症,哮喘,过敏性疾病,皮肤疾病,心血管疾病 ,牛皮癣,炎症性肠病或其他前列腺素和/或白三烯介导的疾病。
