4-oxadaiazoles, a group known for their anti-inflammatory activity, is hybridized with nitric oxide (NO) releasing group, oxime, for its gastro-protective action and potential synergistic effect. The synthesized hybrids were evaluated for their anti-inflammatory, analgesic, antioxidant and ulcerogenic activities. Most of the tested compounds showed excellent anti-inflammatory activity with compound 8e being more
以其消炎活性而闻名的一组新的1,3,4-恶二唑与一氧化氮(NO)释放基团肟发生了杂交,这是因为它具有胃肠保护作用和潜在的协同作用。评价了合成的杂种的抗炎,止痛,抗氧化剂和致溃疡活性。大多数受试化合物均表现出优异的抗炎活性,其中化合物8e的活性比消炎痛更为活跃。他们还显示出中等镇痛活性,但没有抗氧化剂。研究了合成化合物抑制COX-1和COX-2的能力,制备的化合物能够通过IC 50非选择性抑制两种COX。s为0.75–70.50μM。对接研究揭示了被测化合物与同工酶的空袋相互作用的方式。所有合成的化合物都与COXs活性位点相互作用,其能量得分与布洛芬相当。与传统的NSAID相比,所有化合物在胃组织完整性上均显示出更安全的特性。该设计策略应用于布洛芬,以引入布洛芬/恶二唑/ NO杂化物。合成的布洛芬杂种是具有类似抗炎活性但具有更安全的GIT曲线的布洛芬的有前途的替代品。
