  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.

  使用片段和HTS方法论鉴定和优化新型小型c-Abl激酶激活剂。

  摘要：

  Abelson激酶（c-Abl）是一种普遍表达的非受体酪氨酸激酶，在细胞分化和存活中起关键作用。据推测，通过N-末端自抑制“肉豆蔻酰闩锁”的移位，瞬时激活c-Abl激酶可能导致造血干细胞分化增加。这将增加循环中性粒细胞的数量，因此是化疗诱发的中性粒细胞减少症的有效治疗方法。本文介绍了噻唑系列新型小分子c-Abl激活剂的发现和优化，该试剂最初通过高通量筛选得以鉴定。随后，利用片段筛选筛选方法开发的二氢吡唑类似物的改善的理化特性，进行了脚手架跳，并提供了有效的，可溶的，具有细胞活性的c-Abl活化剂，

  This paper describes a general procedure for the synthesis of new substituted thiaisatoic anhydrides or 6- or 7-aryl-1H-thiéno[3,2-d][1,3]oxazine-2,4-diones 3a–j and 4a–f. They were synthesized in large scale under microwave heating conditions with high yields. The reactivity vs nucleophilic reagents of these compounds was studied and permitted to develop a simple combinatorial procedure to synthesize

  hypothesized that transient activation of c-Abl kinase via displacement of the N-terminal autoinhibitory "myristoyl latch", may lead to an increased hematopoietic stem cell differentiation. This would increase the numbers of circulating neutrophils and so be an effective treatment for chemotherapy-induced neutropenia. This paper describes the discovery and optimization of a thiazole series of novel small molecule
