Discovery and characterization of AZD9272 and AZD6538—Two novel mGluR5 negative allosteric modulators selected for clinical development
摘要:
AZD9272 and AZD6538 are two novel mGluR5 negative allosteric modulators selected for further clinical development. An initial high-throughput screening revealed leads with promising profiles, which were further optimized by minor, yet indispensable, structural modifications to bring forth these drug candidates. Advantageously, both compounds may be synthesized in as little as one step. Both are highly potent and selective for the human as well as the rat mGluR5 where they interact at the same binding site than MPEP. They are orally available, allow for long interval administration due to a high metabolic stability and long half-lives in rats and permeate the blood brain barrier to a high extent. AZD9272 has progressed into phase I clinical studies. (C) 2012 Elsevier Ltd. All rights reserved.

pentafluorobenzoate (PFB) and 2,4,6-trifluorobenzoate (TFB) leaving groups have been derived from the solvolysis rateconstants of X,Y-substituted benzhydryl PFBs and TFBs measured in a series of aqueous solvents, by applying the LFER equation: log k = sf(Ef + Nf). The heterolysis rateconstants of dianisylmethyl PFB and TFB, and those determined for 10 more dianisylmethyl benzoates in aqueous ethanol,
五氟苯甲酸酯(PFB)和2,4,6-三氟苯甲酸酯(TFB)离开基团的核官能度是通过应用LFER方程从在一系列水性溶剂中测量的X,Y取代的苯甲基PFB和TFB的溶剂分解速率常数得出的:log k = s f(E f + N f)。二苯胺基甲基PFB和TFB的杂解速率常数,以及在乙醇水溶液中另外10种苯甲酰甲基苯甲酸酯的杂化速率常数,构成了一组参考苯甲酸酯,其实验ΔG with与ΔH correlat相关。(通过PCM量子化学方法计算)模型环氧环的形成。由于具有极好的相关性(r = 0.997),因此已经建立了计算取代苯甲酸酯LG的核官能度的方法,最终提供了一种测定给定溶剂中任何苯甲酸酯的S N 1反应性的方法。使用Δ ģ ⧧ VSΔ ħ ⧧的相关性,并考虑小号˚F基于相似性,已在90%,80%和70%的乙醇水溶液中确定了约70种苯甲酸酯的核官能度参数。计算得出的取代苯甲酸酯离去基团的固有壁垒

single-crystalline metal–organic frameworks (MOFs) are scarce, which prevents synthesis and systematic variation of many potential heterogeneous catalyst materials. Here we demonstrate that metallopolymerization of kinetically inert Ru2 metallomonomers via labile Ag–N bonds provides access to a family of atomically precise single-crystalline Ru2-based coordination polymers with varied networktopology and primary
