As part of a program to establish structure-activityrelationships for vanilloids, analogs of the pungent principle capsaicin, the alkyl chain portion of the parent structure (and relatedcompounds derived from homovanillic acid) was varied. In antinociceptive and antiinflammatory assays (rat and mouse hot plate and croton oil-inflamed mouse ear), compounds with widely varying alkyl chain structures

been synthesized, and a newmethod for the synthesis of these compounds has been developed. The yields range from 48.35 to 98.98%. It has been found that the synthetic capsaicinoids and capsinoids present a lipophilia similar to those of the natural compounds and present similar biological activity. The bioactivity of the synthetic capsaicinoids and capsinoids decreases proportionally to the degree of

and its analogues 3a–3q were designed and synthesized as potential new antioxidant and neuroprotective agents. Many analogues exhibited good antioxidant effects, and some showed more potent free radical scavenging activities than the positive drug quercetin (IC50 = 8.70 ± 1.75 μM for DPPH assay and 13.85 ± 2.87 μM for ABTS assay, respectively). The phenolic hydroxyl of capsaicin analogues was critical
辣椒素及其类似物3a-3q被设计和合成为潜在的新型抗氧化剂和神经保护剂。许多类似物表现出良好的抗氧化作用,其中一些类似物显示出比阳性药物槲皮素更有效的自由基清除活性(DPPH 测定的 IC 50 = 8.70 ± 1.75 μM,ABTS 测定的 IC 50 分别为 13.85 ± 2.87 μM)。辣椒素类似物的酚羟基对于确定抗氧化活性至关重要。在这些化合物中,3k显示出最有效的抗氧化活性。细胞活力测试表明,代表性化合物3k在低浓度下能够很好地保护细胞免受H 2 O 2诱导的氧化损伤(10 μM时细胞活力增加至90.0 ± 5.5%)。此外,研究表明3k可以减少细胞内ROS的积累并增加GSH水平,以防止H 2 O 2诱导的SY5Y细胞氧化应激。线粒体膜电位测定中,3k显着提高经H 2 O 2处理的SY5Y细胞的MMP水平,并起到抗神经细胞死亡的作用。这些结果为开发新型辣椒素类似物作为潜在
