R. S. Pavelyev R. R. Khairullina S. A. Koshkin A. G. Iksanova O. A. Lodochnikova N. N. Khaertdinov G. F. Sitdikova A. F. Safina E. G. Aleksandrova L. E. Ziganshina Yu. G. Shtyrlin 《Russian Chemical Bulletin》2016,65(2):519-531
An approach to the synthesis of epoxides based on 6-hydroxymethylpyridoxine acetals was developed. The epoxides obtained were involved in the ring opening reactions by nitrogen-, oxygen-, and sulfur-containing nucleophiles. Cytotoxicity and antiadrenergic properties of some synthesized compounds were studied on the models in situ and in vivo. 相似文献

The reaction of 4,5-diamino-3-methyl-1-phenylpyrazole with dibenzylideneacetone and its 4,4-derivatives has been studied; the reactions lead to aromatic 1H-2,3-dihydropyrazolo[5,4-b]1,5-diazepine derivatives. The reaction pathway has also been identified.Translated from Khimiya Geterotsiklicheskikh Sodinenii, No. 11, pp. 1563–1567, November, 1987. 相似文献

A convenient method for the synthesis of pyridoxine alkenyl derivatives by the Wittig reaction of [(2,8-dimethyl-4H-[1,3]dioxino[4,5-c]pyridin-5-yl)methyl]triphenylphosphonium chloride with aldehydes was suggested. Some of the compounds obtained exhibit antitumor activity in vitro. 相似文献

Two series of organotin(IV) complexes with Sn–S bonds on the base of 2,6‐di‐tert‐butyl‐4‐mercaptophenol ( L 1 SH ) of formulae Me2Sn(L1S)2 ( 1 ); Et2Sn(L1S)2 ( 2 ); Bu2Sn(L1S)2 ( 3 ); Ph 2 Sn(L1S)2 ( 4 ); (L1)2Sn(L1S)2 ( 5 ); Me3Sn(L1S) ( 6 ); Ph3Sn(L1S) ( 7 ) (L1 = 3,5‐di‐tert‐butyl‐4‐hydroxyphenyl), together with the new ones [Me3SnCl(L2)] ( 8 ), [Me2SnCl2(L2)2] ( 9 ) ( L 2 = 2‐(N‐3′,5′‐di‐tert‐butyl‐4′‐hydroxyphenyl)‐iminomethylphenol) were used to study their antioxidant and cytotoxic activity. Novel complexes 8 , 9 of MenSnCl4 ? n (n = 3, 2) with Schiff base were synthesized and characterized by 1H, 13C NMR, IR and elemental analysis. The crystal structures of compounds 8 and 9 were determined by X‐ray diffraction analysis. The distorted tetrahedral geometry around the Sn center in the monocrystals of 8 was revealed, the Schiff base is coordinated to the tin(IV) atom by electrostatic interaction and formation of short contact Sn–O 2.805 Å. In the case of complex 9 the distorted octahedron coordination of Sn atom is formed. The antioxidant activity of compounds as radical scavengers and reducing agents was proved spectrophotometrically in tests with stable radical DPPH, reduction of Cu2+ (CUPRAC method) and interaction with superoxide radical‐anion. Moreover, compounds have been screened for in vitro cytotoxicity on eight human cancer cell lines. A high activity against all cell lines with IC50 values 60–160 nM was determined for the triphenyltin complex 7 , while the introduction of Schiff base decreased the cytotoxicity of the complexes. The influence on mitochondrial potential and mitochondrial permeability for the compounds 8 and 9 has been studied. It is shown that studied complexes depolarize the mitochondria but don't influence the calcium‐induced mitochondrial permeability transition. 相似文献

The electronic effect of the pyrroline-2,5-dione ring on the benzene ring in the case of N-aryl compounds is close to the effect exerted by halogens. The overall electron-acceptor effect depends markedly on the nature of the solvent. The electron-donor effect of conjugation is small.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 7, pp. 906–910, July, 1976. 相似文献

When uracil is reacted with benzoylamino(chloro)acetophenone, we obtain two amidophenacylation products depending on the condensation conditions. The first product contains an amidophenacyl moiety at the N1 center, and in the second product two such moieties are located at the N1 and N3 centers of the uracil. Treatment of these accessible uracil derivatives with phosphorus oxychloride, thionyl chloride, or phosphorus pentasulfide leads to cyclization of the amidophenacyl side group, which is used to synthesize a number of modified pyrimidine bases with 2,5-diphenyloxazole or 2,5-diphenylthiazole residues. 相似文献
