Antileishmanial, Antimicrobial and Antifungal Activities of Some New Aryl Azomethines
摘要:
合成了一系列十八种腙,由适当的主要芳香胺与芳香和/或杂芳香羧醛反应得到。合成的腙已被评估其体外抗利什曼病、抗菌和抗真菌活性。结果显示大多数合成化合物具有一定的抗真菌活性,而抗利什曼病活性结果则突显所有合成腙均抑制寄生虫生长,其中大多数对利什曼ia major 前鞭毛体表现出高度的有效性。未观察到显著的杀菌活性。

With the aim of identifying novel lead compounds active against emergent human infectious diseases, a series of 2,3‐dihydro‐4H‐pyridinone derivatives has been prepared and evaluated for antiviral activity. Compounds were evaluated in vitro in cell‐based assays for cytotoxicity and against a wide spectrum of viruses. In the antiviral screening, several compounds showed to be fairly active against viruses

could be verified. The electroniceffects of the neighboring aromatic ring substituents systematically modify the sensitivity of the CN group to the electroniceffects of the benzylidene or aniline ring substituents. Electron-withdrawing substituents on the aniline ring decrease the sensitivity of δC(CN) to the substitution on the benzylidine ring, while electron-donating substituents have the opposite
在CDCl 3中,对一系列介晶分子模型化合物(即C 13)测量了13 C NMR化学位移δC (C N)。取代的亚苄基苯胺p -X C 6 H 4 CH NC 6 H 4 p -Y(X = NO 2,CN,CF 3,F,Cl,H,Me,MeO或NMe 2; Y = NO 2,CN ,F,Cl,H,Me,MeO或NMe 2)。δ的取代基依赖性Ç(CN)被用作研究电子取代基对偶氮甲碱单元的作用的工具。亚苄基取代基X有δ的反向效应Ç(C N):吸电子原因屏蔽的取代基,而给电子性的人的行为相反,感应效果清楚地在共振效应为主。相反,苯胺取代基Y发挥正常作用:吸电子取代基引起屏蔽,而供电子取代基引起C N碳屏蔽,感应效应和共振效应的强度非常相似。此外,可以验证X和Y之间是否存在特定的交叉相互作用。相邻芳环取代基的电子效应可系统地改变C的灵敏度N基团对亚苄基或苯胺环取代基的电子作用。吸电子苯胺环上的取代基降低δ的灵敏度Ç(C

The catalytic activity of magnetic Fe3O4nanoparticles to promote the reduction of β-lactams containing nitroaryl groups to β-lactams containing aminoaryl groups in ethanol was reported. This methodology is convenient and green.
FT-IR, 1H NMR, 13C NMR, 31P NMR, ESI-MS and X-ray crystallography. The X-ray analyses reveal that the crystal structures of 1-5 are monoclinic or triclinic system with the space group P 21/c, P-1, P-1, P2(1)/c and P-1, respectively. All P atoms of 1-5 have tetrahedral geometries involving two O-ethyl groups, one Cα atom, and a double bond O atom. The binding interaction of five new α-aminophosphonate

A representative of these non-steroidal compounds (compound 21) was devoid of activity at other nuclear receptors (oestrogen, progesterone, glucocorticoid and mineralocorticoid receptors) in the CV-1 co-transfection
