  Diarylspiro[2.4]heptenes as Orally Active, Highly Selective Cyclooxygenase-2 Inhibitors:  Synthesis and Structure−Activity Relationships

  摘要：

  A novel series of 5,6-diarylspiro[2.4]hept-5-enes was shown to provide highly potent and selective cyclooxygenase-2 (COX-2) inhibitors. A study of structure-activity relationships in this series suggests that 3,4-disubstituted phenyl analogs are generally more selective than 4-substituted phenyl analogs and that replacement of the methyl sulfone group on the B-phenyl ring with a sulfonamide moiety results in compounds with superior in vivo pharmacological properties, although with lower COX-2 selectivity, Several compounds have been shown to possess promising pharmacological properties in adjuvant-induced arthritis and edema analgesia models. The absence of gastrointestinal (GI) toxicity at 200 mpk of several selected compounds in rats and mice corresponds well with the weak potency for inhibition of COX-1 observed in the enzyme assay. Methyl sulfone 55 and sulfonamide 24 were shown to have superior in vivo pharmacological profiles, low GI toxicity, and good oral bioavailability and duration of action.

  targeted by small molecules called generically correctors and potentiators, respectively. Aminoarylthiazoles (AATs) represent an interesting class of compounds that includes molecules with dual activity, as correctors and potentiators. With the aim to improve the activity profile of AATs, we have now designed and synthesized a library of novel compounds in order to establish an initial SAR that may provide

  囊性纤维化跨膜电导调节剂 (CFTR) 是存在于上皮细胞膜中的氯离子通道。影响CFTR的突变基因导致囊性纤维化（CF），一种多器官严重疾病。最常见的 CF 突变 F508del 会损害 CFTR 蛋白的加工和活性（门控）。其他突变，如 G551D，只会导致门控缺陷。加工和门控缺陷可以分别被称为一般校正剂和增强剂的小分子作为目标。氨基芳基噻唑 (AAT) 代表了一类有趣的化合物，包括具有双重活性的分子，作为校正剂和增强剂。为了改善 AAT 的活性特征，我们现在设计并合成了一个新化合物库，以建立一个初始 SAR，该 SAR 可以提供有关对救援活动有益或有害的化学基团的指示。使用功能测定法在表达 CFBE41o 的 F508del-CFTR 中测试了新化合物作为校正剂和增强剂。双重活性化合物 AAT-如图 4a 所示，当与校正剂 VX-809 组合时，其特征在于提高的功效和显着的协同作用。此外，通过计算方法，已检测到核苷酸结合域

  The enzyme 3-mercaptopyruvate sulfurtransferase (3-MST) is one of the more recently identified mammalian sources of H2S. A recent study identified several novel 3-MST inhibitors with micromolar potency. Among those, (2-[(4-hydroxy-6-methylpyrimidin-2-yl)sulfanyl]-1-(naphthalen-1-yl)ethan-1-one) or HMPSNE was found to be the most potent and selective. We now took the central core of this compound and

  3-巯基丙酮酸硫转移酶（3-MST）是最近发现的哺乳动物H 2 S来源之一。最近的一项研究发现了几种具有微摩尔效价的新型3-MST抑制剂。其中，（2-[（（4-羟基-6-甲基嘧啶-2-基）硫烷基] -1-（萘-1-基）乙-1-酮）或HMPSNE是最有效和选择性最大的。现在，我们以该化合物的核心为原料，分别对嘧啶酮和芳基酮进行了修饰。合成了63种化合物的文库；测试化合物的H 2从重组3-MST体外产生S。随后测试活性化合物以阐明其效能和选择性。计算机建模研究已经描述了绑定到3-MST的活动站点所必需的一些关键结构特征。在基于细胞的试验中测试了六种新型3-MST抑制剂：它们对鼠MC38和CT26结肠癌细胞的增殖具有抑制作用；还证实了具有最高效力和最佳基于细胞的活性的化合物的抗增殖作用（1b）对小鼠MC38肿瘤的生长。
