Synthesis and biological evaluation of imidazole-based small molecule antagonists of the melanocortin 4 receptor (MC4-R)
摘要:
A novel series of imidazole-based small molecule antagonists of the melanocortin 4 receptor (MC4-R) is reported. Members of this series have been identified, which exhibit sub-micromolar binding affinity for the MC4-R, functional potency <100nM, and good oral exposure in rat. Antagonists of the MC4-R are potentially useful in the therapeutic treatment of involuntary weight loss due to advanced age or disease (e.g. cancer or AIDS), an area of large, unmet medical need.

一种新的噻吩并[3,2- b ]噻吩异靛蓝(iITT)的合成据报道,该单体单元已经被广泛使用,并且其随后被引入一系列交替共聚物中。通过钯催化的交叉偶联与苯并噻二唑,联噻吩和噻吩共聚单体单元共聚,可得到三种新型的窄带隙半导体聚合物,用于OFET应用。扩展异靛蓝核心的稠合性质可进一步增强沿聚合物主链的分子轨道重叠,并促进良好的电荷传输特性,因此证明了扩展附着在异靛蓝核心上的稠环系统的潜力。当用作顶栅/底接触OFET器件的半导体通道时,观察到良好的双极性特性,空穴和电子迁移率分别高达0.4 cm 2 / Vs和0.7 cm 2/ Vs。这三种新聚合物显示出良好的稳定性,高温退火显示出聚合物结晶度的增加,这直接对应于X射线衍射,原子力显微镜和光热偏转光谱法所显示的电荷载流子迁移率的提高。

capability for asymmetric synthesis of chiral amines from ketones. Reliable high‐throughput activity assay of ω‐TAs is essential in carrying out extensive substrate profiling and establishing a robust screening platform. Here we report spectrophotometric and colorimetric methods enabling rapid quantitation of ω‐TA activities toward ketones in a 96‐well microplate format. The assay methods employ benzylamine
