The respective hydroxypropyl phenyl ethers were obtained by the reaction of 5,5-dimethylhydantoin, morpholine, benzotriazole,
benzimidazole, pyrrolidone, and phthalimide with phenyl glycidyl ether. 8-(2-Hydroxy-3-phenoxy) quinoline was synthesized
by O-alkylation.

The reaction of 5,5-dimethylhydantoin, benzotriazole, benzimidazole, morpholine, pyrrolidone, caprolactam, and phthalimide
with allyl glycidyl ether gave the corresponding heterylhydroxypropyl allyl ethers, the structures of which were confirmed
by spectral data and elemental analysis.

ABSTRACTIn this study, we report the synthesis and biological evaluation of novel phthalimide based Schiff base derivatives as promising antioxidant and DNA-binding agents. The structural investigation of the synthesized compounds was determined by spectral and elemental analysis. In vitro DNA-binding studies of title compounds were carried out by UV–Vis, fluorescence, circular dichroism spectroscopic techniques, cyclic voltammetry, thermal denaturation studies, and hydrodynamic measurements to investigate their potential as DNA-binding agents. The DNA binding constant (Kb) of target compounds was obtained from absorption studies between 1.2 × 105 M?1 and 1.27 × 105 M?1, respectively, suggesting that the test compounds have shown good affinity toward calf-thymus DNA. The experimental results of DNA-binding studies reveal a non-intercalative mode of binding between DNA and the synthesized compounds, most probably groove binding. In addition, molecular docking techniques were performed to rationalize the observed binding affinities with the target DNA. Furthermore, antioxidant and free radical scavenging activities of the synthesized compounds were carried out to find out their pharmacological potential. The results indicate that the title compounds displayed good antioxidant activity against DPPH (IC50: 0.727 and 0.656 mg/mL) and H2O2 radicals (IC50: 1.072 and 0.911 mg/mL) comparable to standard ascorbic acid. 相似文献

Sterically Congested 2,6‐Disubstituted Anilines from Direct C−N Bond Formation at an Iodine(III) Center 下载免费PDF全文

2,6‐Disubstituted anilines are readily prepared from the direct reaction between amides and diaryliodonium salts. As demonstrated for 24 different examples, the reaction is of unusually broad scope with respect to the sterically congested arene and the nitrogen source, occurs without the requirement for any additional promoter, and proceeds through a direct reductive elimination at the iodine(III) center. The efficiency of the coupling procedure is further demonstrated within the short synthesis of a chemerin binding inhibitor. 相似文献

A direct method for the synthesis of functional derivatives ofN-carboxatnidomethyl- and N-phthalimidomethyl-a-amino acids by the reaction of nitriles and amides of -amino acids (including peptides) with formaldehyde and NH-compounds (amides and imides) in DMF in the presence of TsOH was developed. The reactions of the compounds synthesized with acetic anhydride, tosyl chloride, and phcnylalanine benzylamide in the presence of dicyclohexylcarbodiimide affording the corresponding N-acyl and N-sulfonyl derivatives or peptides containing carboxamido- and phthalimidomethyl substituents at the terminal N-atom of the peptide chain, were studied.Translated fromIzvestiya Akademii Nauk.

A one-pot efficient, green, practical, and environmentally friendly multicomponent synthesis of 5-oxo-4-aryl-5,6,7,8-tetrahydro-4H-chromenes, ethyl-6-amino-4-aryl-5-cyano-2-methyl-4H-pyran-3-carboxylates as well as 2-amino-4-aryl-7-hydroxy-4H-chromene-3-carbonitriles via tandem the Knoevenagel-cyclocondensation has been described in the presence of a green, low-cost, mild, efficient, and commercially available potassium phthalimide as the organocatalyst. This technique is a safe and ecofriendly approach to the synthesis of different 4H-chromens and 4H-pyrans that offers many merits including short reaction times, high yields, straightforward work-up, and no use of hazardous organic solvents. 相似文献
