  Novel small molecule inhibitors targeting the “switch region” of bacterial RNAP: Structure-based optimization of a virtual screening hit

  摘要：

  Rising resistance against current antibiotics necessitates the development of antibacterial agents with alternative targets. The "switch region" of RNA polymerase (RNAP), addressed by the myxopyronins, could be such a novel target site. Based on a hit candidate discovered by virtual screening, a small library of 5-phenyl-3-ureidothiophene-2-carboxylic acids was synthesized resulting in compounds with increased RNAP inhibition. Hansch analysis revealed pi (lipophilicity constant) and sigma (Hammet substituent constant) of the substituents at the 5-phenyl moiety to be crucial for activity. The binding mode was proven by the targeted introduction of a moiety mimicking the enecarbamate side chain of myxopyronin into the hit compound, accompanied by enhanced RNAP inhibitory potency. The new compounds displayed good antibacterial activities against Gram positive bacteria and Gram negative Escherichia coli TolC and a reduced resistance frequency compared to the established antibiotic rifampicin.

  设计，合成和生物评价的6-取代的Thieno [3,2-d]嘧啶类似物作为双表皮生长因子受体激酶和微管抑制剂。

  摘要：

  酪氨酸激酶抑制剂与微管靶向剂成功结合的临床证据促使我们设计和开发具有表皮生长因子受体（EGFR）激酶和微管蛋白聚合抑制特性的单一药物。发现了一系列6-芳基/杂芳基-4-（3'，4'，5'-三甲氧基苯胺基）噻吩并[3,2-d]嘧啶衍生物，它们是新型的双微管蛋白聚合和EGFR激酶抑制剂。4-（3'，4'，5'-三甲氧基苯胺基）-6-（对甲苯基）噻吩并[3,2-d]嘧啶衍生物6g是该系列中最有效的化合物，具有抗增殖作用，其中一半最大抑制浓度（IC50）值在一位或两位数纳摩尔范围内。化合物6g与秋水仙碱位点的微管蛋白结合并抑制微管蛋白组装，IC50值为0.71μM，6g抑制EGFR活性，IC50值为30 nM。我们的数据表明，6g优异的体外和体内特性可能源于其对微管蛋白聚合和EGFR激酶的双重抑制作用。

  A preliminary in vitro screening of compounds belonging to various chemical families from our library revealed the thieno[3,2-d]pyrimidin-4(3H)-one scaffold displayed a promising profile against Plasmodium falciparum. Then, 120 new derivatives were synthesized and evaluated in vitro; compared to drug references, 40 showed good activity toward chloroquine sensitive (IC50 35-344 nM) and resistant (IC50 45-800 nM) P. falciparum strains. They were neither cytotoxic (CC50 15-50 mu M) toward HepG2 and CHO cells, nor mutagenic. Structure activity relationships were defined. The lead-compound also appeared active against the Plasmodium liver stages (Plasmodium yoelii IC50 = 35 nM) and a preliminary in vivo evaluation indicated the in vitro activity was preserved (45% reduction in parasitemia compared to untreated infected mice). A mechanistic study demonstrated these molecules do not involve any of the pathways described for commercial drugs and exert a specific activity on the ring and trophozoite stages. 2015 Elsevier Masson SAS.

  The high expression of MCH in the hypothalamus with the lean hypophagic phenotype coupled with increased resting metabolic rate and resistance to high fat diet-induced obesity of MCH KO mice has spurred considerable efforts to develop small molecule MCHR1 antagonists. Starting from a lead thienopyrimidinone series, structure-activity studies at the 3- and 6-positions of the thienopyrimidinone core afforded potent and selective MCHR1 antagonists with representative examples having suitable pharmacokinetic properties. Based on structure-activity relationships, a structural model for MCHR1 was constructed to explain the binding mode of these antagonists. In general, a good correlation was observed between pK(a)s and activity in the right-hand side of the template, with Asp123 playing an important role in the enhancement of binding affinity. A representative example when evaluated chronically in diet-induced obese mice resulted in good weight loss effects. These antagonists provide a viable lead series in the discovery of new therapies for the treatment of obesity.
