  2-Ethynylbenzenealkanamines. A new class of calcium entry blockers

  摘要：

  A series of 2-(aryl- or alkylethynyl)benzenealkanamines were synthesized. They exhibit antihypertensive activity in spontaneously hypertensive rats and coronary vasodilator activity with minimal negative inotropic activity in the "Langendorff" guinea pig heart in vitro. They have been shown to exert their activity by inhibition of Ca2+ influx across cell membranes. Optimal activity is found among the N-(arylethyl)-5-methoxy-alpha-methyl-2-(phenylethynyl)ben zeneethanamines and -propanamines.

  attractive strategy for treating diseases associated with P. aeruginosa infection. In this study, we designed and synthesized a series of gingerol analogs targeting LasR, a master regulator of quorum sensing networks in P. aeruginosa. Structure–activity relationship studies showed that a hydrogen-bonding interaction in the head section, stereochemistry and rotational rigidity in the middle section, and optimal

  铜绿假单胞菌是免疫功能低下患者慢性感染的病原体。仲裁感应电路的中断是一种有吸引力的策略，用于治疗与铜绿假单胞菌感染相关的疾病。在这项研究中，我们设计和合成了一系列针对LasR的姜醇类似物，LasR是铜绿假单胞菌群体感应网络的主要调节剂。结构-活性关系研究表明，头部的氢键相互作用，中部的立体化学和旋转刚度以及尾部的最佳烷基链长度是增强LasR结合亲和力和抑制作用的重要因素。生物膜形成的过程。最有效的化合物41，类似物为（与已知的LasR拮抗剂（S）-6-姜油醇相比，R）-8-姜油醇旋转受限，显示出更强的LasR结合亲和力和生物膜形成抑制作用。这种新的LasR拮抗剂可以用作开发抗生物膜药物以治疗铜绿假单胞菌感染的早期先导化合物。

  β2-adrenoceptor agonists with an 8-(2-amino-1-hydroxyethyl)-6-hydroxy-1,4-benzoxazine-3(4H)-one moiety is presented. The stimulatory effects of the compounds on human β2-adrenoceptor and β1-adrenoceptor were characterized by a cell-based assay. Their smooth muscle relaxant activities were tested on isolated guinea pig trachea. Most of the compounds were found to be potent and selective agonists of the β2-adrenoceptor

  bismuth-catalyzed conjugate reduction protocol that allows for the catalytic regioselective formation of substituted ketones from enones under mild conditions has been developed. We have shown for the first time that the combined poly(methylhydro)siloxane-malononitrile system can serve as an efficient reductant/reagent in 1,4-conjugate reduction of enones. The regioselectivity, efficiencies, and experimental

  已经开发了一种非常简单、直接、铋催化的共轭还原方案，该方案允许在温和条件下从烯酮催化区域选择性形成取代的酮。我们首次证明了组合的聚（甲基氢）硅氧烷 - 丙二腈系统可以在烯酮的 1,4-共轭还原中用作有效的还原剂/试剂。本方法的区域选择性、效率和实验简单性补充了以前在铜或钯催化还原中使用的更复杂的方法。由于其温和的反应条件和结合使用聚（甲基氢）硅氧烷和丙二腈进行选择性还原的有趣化学反应，该方法应该被证明是有吸引力的。

  Isomerization of oxime derivatives was researched in detail to find out the methods for the syn-anti isomerization of O-substituted oximes. Based on these findings were developed simple methods for the preparation of aza-heterocycles from both stereo­isomers of oximes. Quinolines were synthesized from β-aryl ketone oximes by treatment with trifluoroacetic anhydride and 4-chloranil. γ,δ-Unsaturated O-methoxyacetyloximes were transformed to 2H-dihydropyrroles by reaction with methoxy-acetic acid.

  Friedel-Crafts allylation. The entire sequence forms three carbon-carbon bonds and a carbon-halogen bond, generating halocyclopentene adducts in one pot from simple precursors. The process occurs with excellent diastereocontrol, providing highly functionalized polycycles containing three tertiary or quaternary stereogenic centers in a linear array. It is even possible to install three contiguous all-carbon quaternary
