  2-(4-Chlorobenzyl)-3-hydroxy-7,8,9,10-tetrahydrobenzo[H]quinoline-4-carboxylic Acid (PSI-697):  Identification of a Clinical Candidate from the Quinoline Salicylic Acid Series of P-Selectin Antagonists

  摘要：

  P-selectin-PSGL-1 interaction causes rolling of leukocytes on the endothelial cell surface, which subsequently leads to firm adherence and leukocyte transmigration through the vessel wall into the surrounding tissues. P-selectin is upregulated on the surface of both platelets and endothelium in a variety of atherosclerosis-associated conditions. Consequently, inhibition of this interaction by means of a small molecule P-selectin antagonist is an attractive strategy for the treatment of atherosclerosis. High-throughput screening and subsequent analoging had led to the identification of compound 1 as the lead candidate. Herein, we report the continuation of this work and the discovery of a second-generation series, the tetrahydrobenzoquinoline salicylic acids. These compounds have improved pharmacokinetic properties, and a number of them have shown oral efficacy in mouse and rat models of atherogenesis and vascular injury. The lead 31 (PSI-697), is currently in clinical development for the treatment of atherothrombotic vascular events.

  Oxidation of indole-3-acetic acid and its derivatives by peroxidases such as that from horseradish produces many products, including 3-methylene-2-oxindoles. These have long been associated with biological activity, but their reactivity has not been characterized. We have previously demonstrated the potential value of substituted indole acetic acids and horseradish peroxidase as the basis for targeted

  吲哚-3-乙酸及其衍生物被辣根等过氧化物酶氧化后，会产生许多产物，包括3-亚甲基-2-氧吲哚。长期以来，这些都与生物活性有关，但尚未对其反应性进行表征。以前我们已经证明了取代的吲哚乙酸和辣根过氧化物酶作为靶向癌症治疗的基础的潜在价值，因为当观察到高细胞毒性时，化合物被氧化之前具有低细胞毒性。前药和酶的结合会消耗细胞内的硫醇。在这项研究中，合成了在3位，4位，5位或6位被甲基，F或Cl取代的3-亚甲基-2-氧吲哚及其衍生物，它们对代表性的巯基亲核试剂（谷胱甘肽，半胱氨酸，和半胱氨酸肽）使用停止流动力学分光光度法测量。在25°C的pH 7.4下，速率常数在大约2 x 10（3）到2 x 10（4）M（-）（1）s（-）（1）的范围内，这意味着数十倍的寿命这些亚甲基羟吲哚在细胞环境中的传播时间为毫秒，扩散距离为几微米。不出所料，卤素取代降低了辣根过氧化物酶处理中亚甲基羟吲哚的生成速率。使用中国仓

The 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2 H-tetrazolium (MTS) cell viability assays revealed that 56, the ethyl ester of 53, was more potent than 53 in inhibiting viability of most of the Wnt/β-catenin hyperactive

  β-catenin/ T细胞因子（Tcf）蛋白质-蛋白质相互作用（PPI）在β-catenin信号通路中起着至关重要的作用，而该信号通路在许多癌症和纤维化中均被过度激活。基于旨在靶向β-catenin的Tcf4 G13ANDE17结合位点的化合物1，进行了广泛的结构-活性关系研究。结果，发现化合物53和57分别破坏Ki-值为0.64和0.44μM的β-catenin/ Tcf PPI，并且相对于β-catenin/ E-cadherin和β-catenin/ E-cadherin表现出良好的选择性。 β-catenin/腺瘤性息肉病（APC）PPI。3-（4,5-二甲基噻唑-2-基）-5-（3-羧基甲氧基苯基）-2-（4-磺基苯基）-2 H-四唑（MTS）细胞活力测定显示56，53的乙酯，在抑制大多数Wnt /β-catenin过度活跃的癌细胞的生存力上，它比53更有效。进一步的基于细胞的研究表明56破坏了β-catenin/

  Substituted indole-3-acetic acid (IAA) derivatives, plant auxins with potential for use as prodrugs in enzyme-prodrug directed cancer therapies, were oxidised with horseradish peroxidase (HRP) and toxicity against V79 Chinese hamster lung fibroblasts was determined. Rate constants for oxidation by HRP compound I were also measured. Halogenated IAAs were found to be the most cytotoxic, with typical

  Phidianidines A and B are two novel marine indole alkaloids bearing an uncommon 1,2,4-oxadiazole ring and exhibiting various biological activities. Our previous research showed that the synthesized phidianidine analogs had the potential to inhibit the activity of protein tyrosine phosphatase 1B (PTP1B), a validated target for Type II diabetes, which indicates that these analogs are worth further structural
