Synthesis of novel 2-(1-adamantanylcarboxamido)thiophene derivatives. Selective cannabinoid type 2 (CB2) receptor agonists as potential agents for the treatment of skin inflammatory disease
A set of CB2R ligands, based on the thiophene scaffold, was synthesized and evaluated in in vitro assays. Compounds 8c-i, k, l, bearing the 3-carboxylate and 2-(adamantan-1-yl)carboxamido groups together with apolar alkyl/aryl substituents at 5-position or at 4- and 5-positions of the thiophene ring possess high CB2R affinity at low nanomolar concentration, good receptor selectivity, and agonistic
previously reported the synthesis and the pharmacological characterization of a family of methyl 2-(acylamino)thiophene-3-carboxylates as GABAB positive allosteric modulators active both in vitro and in vivo. In the present work, we describe the synthesis of new compounds based on the bioisosteric replacement of the ester moiety with amido or heterocyclic groups as well as of thieno[2,3-d]pyrimidine derivatives
我们之前已经报道了2-(酰基氨基)噻吩-3-羧酸甲酯作为GABA B阳性变构调节剂在体外和体内均具有活性,其合成和药理学表征。在当前的工作中,我们描述了基于酰胺基或杂环基团的酯部分的生物等位取代以及作为其刚性类似物的噻吩并[2,3- d ]嘧啶衍生物的合成,合成新化合物。4 H-噻吩并[2,3- d ] [1,3]恶嗪-4-酮被用作合成中间体,以制备其中一些化合物。恶嗪酮11b,16和17的结构X射线晶体学研究确定了这些化合物的存在,这无疑排除了先前为这些化合物所假定的同分异构的β-内酰胺结构。无论是变构还是正构配体,这些新分子均未在GABA B受体上显示出显着活性。
SAR156497, an Exquisitely Selective Inhibitor of Aurora Kinases
demonstrated and have prompted intensive search for small molecule Aurora inhibitors. Indeed, over 10 of them have reached the clinic as potential anticancer therapies. We report herein the discovery and optimization of a novel series of tricyclic molecules that has led to SAR156497, an exquisitelyselective Aurora A, B, and C inhibitor with in vitro and in vivo efficacy. We also provide insights into its
