Electronic Spectral Properties of Substituted Arylazothiobarbiturate Compounds in the Presence of Different Solvents

Abstract

The electronic absorption spectra of 5-(substituted phenylazo) thiobarbituric acid compounds in the presence of different solvents are analyzed by the multiple regression technique using the equation:

Spectrophotometric studies on some arylazo diamino pyrimidinol in organic solvents and in buffer solutions

“…Various reports had appeared recently discussing the electronic spectral properties of pyrimidine bases and their derivatives [12][13][14][15][16][17][18][19][20][21][22][23]. Pyrimidine is an active component of antibiotics and antineoplastics (e.g.…”

Solvatochromism and potentiometic studies of some active nitroso- and nitroso-azo- compounds

“…Moreover, certain pyrimidine-pyrazoles have been studied in the fight against cancer [9][10][11][12][13][14][15][16][17]. In our laboratory, Masoud et al recently reported a detailed structural chemistry of azo and nitroso metal complexes [18][19][20][21][22][23][24][25][26] based on spectral and magnetic susceptibility measurements. The following paper aimed to study the stability of biologically active nitroso and nitroso-azo compounds (Scheme 1).…”

Solvatochromaticity and pH dependence of the electronic absorption spectra of some purines and pyrimidines and their metal complexes

“…Attention in our laboratory has escalated regarding the potential of those compounds and their complexes owing to their applicability as potential ligands for a large number of metal ions [2][3][4][5][6][7][8][9][10][11][12][13]. Compounds containing nitrogen and sulphur as donor atoms such as thiouracil (TU) and 6-amino-2-thiouracil (ATU) have an important role to play as anti-cancer and anti-viral activities [14].…”
