A versatile and highly stereoselective borylative cyclization to generate polyfunctionalized γ-lactams has been developed. The stereoselective synthesis of these key ring systems is crucial due to their ubiquity in natural products. We report the diastero- and enantioselective construction of di- and trisubstituted γ-lactam cores, with examples containing an enantioenriched quaternary carbon.
Synthesis of 4-(3-oxo-3-phenylpropyl)morpholin-4-ium chloride analogues and their inhibitory activities of nitric oxide production in lipopolysaccharide-induced BV2 cells
analogue, inhibited nitricoxide (NO) production, in this paper, various substituted benzene analogues with morpholine hydrochloride of 2 were synthesized and their inhibitory effects on NO production in lipopolysaccharide (LPS)-induced BV2 cells were tested. Among the synthesized compounds, 2-trifluoromethyl analogue 16n (IC50 = 8.6 μM) showed a significantly higher inhibitoryactivity than that of the
根据我们之前的报道,3-morpholino-1-phenylpropan-1-one 2是氟西汀的简化吗啉类似物之一,可抑制一氧化氮 (NO) 的产生,在本文中,本文合成了各种取代苯类似物与盐酸吗啉的2并测试了它们对脂多糖 (LPS) 诱导的 BV2 细胞中 NO 产生的抑制作用。在合成的化合物中,2-三氟甲基类似物16n (IC 50 = 8.6 μM) 显示出比母体化合物2a (IC 50 > 50 μM)显着更高的抑制活性,并且剂量依赖性地抑制 NO 产生而没有细胞毒性。化合物16n还在 2、10 和 20 μM 浓度下抑制 LPS 诱导的 BV2 细胞中 iNOS 的表达。这些结果表明,化合物16n通过抑制 iNOS 的表达来抑制 NO 的产生,并且可以用作开发新的 NO 产生抑制剂的先导结构。

The synthesis and photophysical properties of a series of yellow-green to blue-green emitting heteroleptic, cyclometalated Pt(II)(acac) complexes based on substituted phenylpyridine and tetrahydroquinoline ligands is reported. The luminescence intensities and lifetimes of these compounds were also studied in poly(styrene) films with respect to their responses to oxygen and temperature. Particularly
