  对淀粉样蛋白-β 寡聚化和原纤维化具有不同抑制作用的阿魏酸酰胺衍生物

  摘要：

  阿尔茨海默病 (AD) 是一种进行性神经退行性疾病，其部分特征是淀粉样蛋白 β (Aβ) 的错误折叠、寡聚化和纤维化。有证据表明，支持 Aβ 寡聚化和随后的原纤维化的机制是不同的，因此可能需要同样不同的治疗方法。先前的研究表明，阿魏酸的酰胺衍生物（一种天然多酚）可以对抗多种 AD 病理，但其对 Aβ 聚集的影响存在争议。我们设计并合成了一个系统的阿魏酸酰胺衍生物文库，并独立评估了它们的抗寡聚和抗原纤维能力。氮杂环丁烷束缚的三苯基衍生物是最有效的抗寡聚剂（化合物2i：IC 50 = 1.8 µM ± 0.73 µM)；值得注意的是，这些只是适度的抗原纤维剂（20.57% 的原纤维化抑制），并且证明了抗寡聚/原纤维活性之间的相关性较差。这些数据随后被编入了一个in silico QSAR 模型，该模型产生了一个强大的抗 Aβ 寡聚活性预测模型（测试集的 κ = 0.919；验证集的 κ = 0

  Phenylsulfonylfuroxan NO-donor phenols: Synthesis and multifunctional activities evaluation

  摘要：

  Phenylsulfonyfuroxan nitric oxide (NO)-donor phenols were designed, synthesized and evaluated. The compounds were designed through a symbiotic approach using selected phenols and phenylsulfonylfuroxan NO-donor. The antioxidant activities of the hybrid compounds T-2-T-6 showed to be good in vivo. Compounds T-4 and T-6 revealed excellent yeast alpha-glucosidase inhibitory activity and anti-glycosylation activity. All of the compounds exhibited strong NO releasing activity and significant anti-platelet aggregation activity. The inhibition of platelet aggregation was more than 50% at low concentration (1.5 mu M) and 95% at higher concentration (15 mu M and 150 mu M). The vasodilatation experiment demonstrated that the six compounds under test exhibited definite vasodilation activity (pIC(50) ranged from 5.698 to 6.383), especially compound T6 (pIC(50) was 6.383) which was similar to sodium nitroprusside (pIC(50) was 6.786). Both anticoagulant and vasodilatation effects were correlated with their NO releasing activities. These hybrid phenylsulfonyfuroxan-based NO-donor phenols offer a multifunctional prodrug design concept for the development of therapeutic or preventive agents for metabolic syndrome.

  A series of novel 2-phenylaminopyrimidine (PAP) derivatives structurally related to STI-571 were designed and synthesized. The abilities of these compounds to inhibit proliferation were tested in human chronic myeloid leukemia K562 cells. (E)-3-(2-bromophenyl)-N-[4-methyl-3-(4-pyridin-3-yl-pyrimidin-2-ylamino)phenyl]acrylamide(12d) was the most effective cell growth inhibitor and was 3-fold more potent than STI-571.
