Discovery of an Isothiazole-Based Phenylpropanoic Acid GPR120 Agonist as a Development Candidate for Type 2 Diabetes
摘要:
We have discovered a novel series of isothiazole-based phenylpropanoic acids as GPR120 agonists. Extensive structure activity relationship studies led to the discovery of a potent GPR120 agonist 4x, which displayed good EC50 values in both calcium and beta-arrestin assays. It also presented good pharmaceutical properties and a favorable PK profile. Moreover, it demonstrated in vivo antidiabetic activity in C57BL/6 DIO mice. Studies in WT and knockout DIO mice showed that it improved glucose handling during an OGTT via GPR120. Overall, 4x possessed promising antidiabetic effect and good safety profile to be a development candidate.
通过将[3-(2-氨基乙基)氨基丙基]三乙氧基硅烷和磺酸依次锚固在二氧化硅包覆的Fe 3 O 4表面上,合成了一种新型的磁性纳米粒子负载的酸基双功能催化剂纳米粒子。所制备的纳米颗粒催化剂被用作苯甲醛二甲基乙缩醛和丙二腈的一锅脱缩醛-Knoevenagel串联反应的“准均相”和可回收催化剂。它显示出高的催化活性,因为反应进行得很顺利,并以优异的收率得到了亚苄基丙二腈。此外,由于两个催化部分在相同的MNP上连接在一起,因此在串联反应过程中具有协同作用并促进了传质过程。此外,在六次运行后,该催化剂可以容易地在外部磁场下回收并重复使用,而催化活性没有任何显着损失。

new esters linked pyrazolo[3,4-d]pyrimidinones hybrids 7a-f. The reaction of compound 2 with 3-propargyl bromide gave the compound 8 used as a dipolarophile to access to triazoles (4- and 5-regioisomers (9a-e) and (10a-e), respectively) via the 1,3-dipoar cycloaddition reaction. Finally, condensation reaction of aminopyrazole 1b with α-cyanocinnamonitiles gave the new pyrazolo[1,5-a]pyrimidine-3,6-dicarbonitriles

analyses, IR, UV–vis, and 1H and 13C1H} NMR spectroscopic techniques. The solid-statestructures of complexes 1, 3, and 4 have been determined by single-crystal X-ray crystallography as well as powder X-ray diffraction. Single-crystal X-ray crystallography revealed a monomeric structure for complex 1 but 1Dpolymericstructures for complexes 3 and 4. In all complexes, dithiocarbamate ligands are bonded

Ionicliquids of amino acid amide were synthesized and used as an efficient catalyst for solvent-free Knoevenagelcondensation. Synthesized ionicliquids are an environmentally benign, inexpensive, metal free and plays the dual role of solvent as well as an efficient catalyst for Knoevenagelcondensation. A wide range of aliphatic, aromatic and heteroaromatic aldehydes easily undergo condensation with

Herein, to further study the application potential of this material, a covalently bonded nickel catalyst based on the alkynyl-tagged UiO-66-alkyne has been prepared and afforded us unprecedented highly dispersed and highlyefficient catalytic active species. Meanwhile, this nickel-contained catalyst method for joining metals provided
