努力开发了一系列苯并噻唑和喹啉稠合的生物活性化合物,这些生物活性化合物是通过使用一系列取代的乙酰乙酰苯胺通过四步合成路线而获得的。获得N-(苯并[ d ]噻唑-2-基)-2-羟基喹啉-4-羧酰胺(6a-1)的收率高达96%,而环保型p-TSA用作催化剂。此外,使用一系列癌细胞系(从MCF-7(乳腺癌),HCT-116(结肠癌),PC-3和LNCaP(前列腺)和SK-HEP-1(肝癌)。由于抗氧物质(ROS)对癌症的发展至关重要,因此在抗癌研究之前,也对本研究化合物的抗氧化性能进行了验证。为了确定所述化合物的细胞膜稳定性作用,确定了基于人红细胞(HRBC)的膜保护测定法。结果为化合物6a-1与本研究中使用的其他细胞系相比,它们能够在PC3细胞系(前列腺癌)上产生主要的结果值。由于已知人类生殖细胞碱性磷酸酶(hGC-ALP)在前列腺癌发展中的连通性,因此评估了活性最高的化合物对hGC-ALP的
Direct enantioselective hydrogenation of unsaturated compounds to generate chiral three-dimensional motifs is one of the most straightforward and important approaches in synthetic chemistry. We realized the Ru(II)-NHC-catalyzed asymmetrichydrogenation of 2-quinolones under mild reaction conditions. Alkyl-, aryl- and halogen-substituted optically active dihydro-2-quinolones were obtained in high yields
A series of novel phenothiazinyldihydropyridine dicarboxamides7a–7jwas synthesized by adopting a multi-step synthetic strategy and characterized through physical and spectral techniques.
standard diclofenac sodium. A hybrid integrated with a para-fluorophenyl carboxamide moiety (28) showed the highest DPPH radical scavenging activity among the chemical entities synthesized. Furthermore, the results of anticancer evaluations implied that the hybrid tethered with a phenyl carboxamide structural unit (29) exerted superior activity when compared with other hybrids against the pancreatic cancer

A facile and efficient AgI-catalytic approach is reported for the first time to synthesize β-oxoamides from β-oxo esters a with broad substrate scope in good to excellent yields. Crossover and in situ NMR studies confirmed that the reaction occurred through a new pathway and not by the traditional condensation reaction. The key advantages of this method are the readily available starting materials
