The invention relates to a new preparation method of derivatives of substituted 2-arylaikanoic acids. The compounds are used for the preparation of histaminically active compounds and antiphlogistics. The compounds are prepared by reaction of suitably substituted a-halogen acetophenones with orthoformates with catalysis by mineral and Lewis acids.
Discovery of 6-Phenylpyrimido[4,5-<i>b</i>][1,4]oxazines as Potent and Selective Acyl CoA:Diacylglycerol Acyltransferase 1 (DGAT1) Inhibitors with in Vivo Efficacy in Rodents
The discovery and optimization of a series of acyl CoA:diacylglycerol acyltransferase 1 (DGAT1) inhibitors based on a pyrimido[4,5-b][1,4]oxazine scaffold is described. The SAR of a moderately potent HTS hit was investigated resulting in the discovery of phenylcyclohexylacetic acid 1, which displayed good DGAT1 inhibitory activity, selectivity, and PK properties. During preclinical toxicity studies
描述和优化了一系列基于嘧啶[4,5- b ] [1,4]恶嗪骨架的酰基辅酶A:二酰基甘油酰基转移酶1(DGAT1)抑制剂。对中等强度HTS命中的SAR进行了研究,结果发现了苯基环己基乙酸1,该苯基环己基乙酸显示出良好的DGAT1抑制活性,选择性和PK性能。在临床前毒性研究过程中,观察到代谢物1升高了肝酶ALT和AST的水平。随后,合成类似物以排除有毒代谢物的形成。这项工作导致发现了螺螺茚满42,与1相比,螺螺茚满42显示出对DGAT1抑制作用的显着改善。。Spiroindane 42在啮齿动物体内具有良好的耐受性,在小鼠口服甘油三酸酯摄取研究中显示出功效,并且在临床前毒性研究中具有可接受的安全性。
A novel norbornene-based hydrophobictag was developed that expands the clinical potential of targeted proteindegradation technologies. The degrader Hyt-9, which was obtained by connecting an ALK ligand with norbornene, exhibited potent antiproliferative and degradative activities in vitro and in vivo. Furthermore, norbornene could be used to degrade EZH2 when tagged with the EZH2 inhibitor tazemetostat
A series of novel anaplastic lymphoma kinase (ALK) degraders were designed and synthesized based on proteolysis-targetingchimera (PROTAC) technology by linking two alectinib analogs (36 and 37) with pomalidomide through linkers of different lengths and types. The most promising degrader 17 possessed a high ALK-binding affinity and potent antiproliferative activity in the ALK-dependent cell lines and
