  咪唑并[2,1-i]嘌呤-5-酮和相关三环水溶性嘌呤衍生物：有效的 A(2A)-和 A(3)-腺苷受体拮抗剂。

  摘要：

  一系列由黄嘌呤衍生物衍生的三环咪唑并[2,1-i]嘌呤酮和扩环类似物已被制备作为腺苷受体（AR）拮抗剂。与黄嘌呤相比，三环化合物由于碱性氮原子在生理条件下可以质子化而表现出更高的水溶性。引入的取代基分别赋予 A(2A) 或 A(3) AR 较高的亲和力。开发了一种新的毛细管电泳方法，使用天然和改性 β-环糊精作为手性鉴别剂来测定选定手性产物的对映体纯度。这些化合物在大鼠脑 A(1) 和 A(2A) AR 的放射性配体结合测定中进行了研究。另外，还对选定的化合物进行了人重组 A(3) AR 的放射性配体结合测定以及大鼠脂肪细胞膜的 A(1) AR、大鼠 PC 12 细胞膜的 A(2A) AR 的功能研究（腺苷酸环化酶测定）、和小鼠 NIH 3T3 细胞膜的 A(2B) AR。结构-活性关系与相应的黄嘌呤衍生物相似。与 8-苯乙烯基黄嘌呤衍生物相比，2-苯乙烯基咪唑嘌呤酮对 A(2A) AR 的效力较低。

  Allosteric Competitive Inhibitors of the Glucose-1-phosphate Thymidylyltransferase (RmlA) from Pseudomonas aeruginosa

  摘要：

  Glucose-1-phosphate thymidylyltransferase (RmlA) catalyzes the condensation of glucose-1-phosphate (G1P) with deoxy-thymidine triphosphate (dTTP) to yield dTDP-D-glucose and pyrophosphate. This is the first step in the L-rhamnose biosynthetic pathway. L-Rhamnose is an important component of the cell wall of many microorganisms, including Mycobacterium tuberculosis and Pseudomonas aeruginosa. Here we describe the first nanomolar inhibitors of P. aeruginosa RmlA. These thymine analogues were identified by high-throughput screening and subsequently optimized by a combination of protein crystallography, in silico screening, and synthetic chemistry. Some of the inhibitors show inhibitory activity against M. tuberculosis, The inhibitors do not bind at the active site of RmlA but bind at a second site active site. Despite this, the compounds act as competitive inhibitors of G1P but with high cooperativity. This novel behavior was probed by structural analysis, which suggests that the inhibitors work by preventing RmlA from undergoing the conformational change key to its ordered bi-bi mechanism.

  Fragment‐based drug design was used to identify Mycobacterium tuberculosis (Mtb) dihydrofolate reductase (DHFR) inhibitors. Screening of ligands against the Mtb DHFR enzyme resulted in the identification of multiple fragment hits with IC50 values in the range of 38–90 μM versus Mtb DHFR and minimum inhibitory concentration (MIC) values in the range of 31.5–125 μg/mL. These fragment scaffolds would

  New convenient conditions for benzimidazole and benzothiazole syntheses are described. A set of benzimidazoles, 3H-imidazo[4,5-b]pyridines, purines, xanthines and benzothiazoles was readily prepared from (hetero)aromatic ortho-diamines or ortho-aminothiophenol and aldehydes using chlorotrimethylsilane in DMF as a promoter and water-acceptor agent, followed by oxidation with air oxygen.
