  (Imidazo[1,2-a]pyrimidin-2-yl)phenylmethanones and related compounds as potential nonsedative anxiolytics

  摘要：

  Several series of heterocyclic carboxylic esters were found to be active in the benzodiazepine receptor binding assay, a typical example being ethyl 7-ethyl-5-methoxyimidazo[1,2-a]quinoline-2-carboxylate (4b) with an IC50 of 150 nM. The corresponding phenylmethanone 5d was more potent with an IC50 of 14 nM and was orally active in animal models thought to predict anxiolytic effects. The synthesis of a large number of compounds resulted in the optimization of this activity in a series of (imidazo[1,2-a]pyrimidin-2-yl)phenylmethanones of which compounds 7e, 8b, 8h, 8j, and 8k were equipotent with chlordiazepoxide while exhibiting reduced anticonvulsant activity, little or no muscle relaxation, and negligible sedative effects.

  unprecedented catalyst-free microwave-assisted procedure for synthesizing benzo[d]imidazo[2,1-b]thiazoles and N-alkylated 2-aminobenzo[d]oxazol in green media was developed. The transformation provided rapid access to functionalized benzo[d]imidazo[2,1-b]thiazoles from 2-aminobenzothiazole and N-alkylated 2-aminobenzo[d]oxazole from 2-aminobenzoxazole scaffolds under mild transition-metal-free conditions.

  R and S configurations in the GC1 intermediate. Hydrophobic stacking interactions between the tricyclic C7 substituent and a tyrosine side chain, rather than electrostatic or hydrogen bonding by the C3 carboxylic acid group, dominate in both complexes. The formation of the 1,4- thiazepine ring structures is proposed based on a 7-endo-trig cyclization.

  描述和设计了一系列七个作为新的A类和C类丝氨酸β-内酰胺酶抑制剂的三环6-亚甲基Penems。这些化合物被证明是TEM-1和AmpCβ-内酰胺酶的有效抑制剂，而对B类金属-β-内酰胺酶CcrA的抑制作用则较小。与哌拉西林联合使用时，它们的体外活性增强了来自各种细菌的所有C类抗药性菌株的敏感性。已经建立了A类SHV-1和C类GC1酶与17种丝氨酸结合的反应中间体的晶体结构，分别具有2.0 A和1.4 A的分辨率，并被精制为等于0.163和0.145的R因子。在两个β-内酰胺酶中，都形成了一个七元的1,4-硫氮平环。环中的立体C7原子在SHV-1中间体中具有R构型，在GC1中间体中具有R和S构型。三环C7取代基和酪氨酸侧链之间的疏水堆积相互作用，而不是通过C3羧酸基团的静电或氢键键合，在两种络合物中都占主导地位。基于7-内-trig环化，提出了1，4-硫氮平环结构的形成。

  benzothiazoles. When the C2 position of benzothiazole is linked to a C–H or C–C bond, benzo[d]imidazo[2,1-b]thiazoles are obtained through a novel rearrangement via C–S bond cleavage and formation of a new C–S bond. When 2-chloro- or 2-bromobenzothiazoles are used under the same reaction conditions, the isomeric benzo[d]imidazo[5,1-b]thiazoles are formed selectively. These reactions proceed smoothly in moderate

  通过α-亚甲基异氰化物与苯并噻唑的铜促进的环加成反应，已开发出可调谐途径生成苯并[ d ]咪唑并噻唑的两种异构体。当苯并噻唑的C2位置与C–H或C–C键相连时，通过C–S键的裂解和新C的形成，通过新颖的重排可以获得苯并[ d ]咪唑基[2,1- b ]噻唑–S键。当在相同反应条件下使用2-氯-或2-溴苯并噻唑时，选择性地形成异构体苯并[ d ]咪唑并[5，1- b ]噻唑。这些反应在室温下以中等至极好的收率顺利进行，并且可以容忍各种官能团。
