Thermal properties of some CoII, NiII and CuII complexes of new substituted pyrimidine compounds

New pyrazole‐4‐carbothioamide‐based metal complexes: Synthesis, spectral characterization, computational, antimicrobial, and antitumor investigations

“…Also, this residual species contains two metal ions that could be taken as an additional support of the dinuclear character of Ni(II) and Cu(II) complexes as reported analogous pyrazolone and pyrimidine complexes. [ 45 ] However, the final residue is assigned as Fe(SCN) 3 in case of mononuclear octahedral Fe(III) complexes (Table 2). It is worthy to state that the formation of such residues at such elevated temperature range (approximately 800°C) appears as an indication of their higher stability.…”

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).…”

Thermal properties of some biologically active 5-(p-substituted phenylazo)-6-aminouracil complexes

“…The rich chemistry of the azo compounds is associated with several important biological reactions such as protein synthesis, carcinogenesis, azo reduction monoamine oxidase inhibition mutagenic, immunochemical affinity labeling, nitrogen fixation, important medical and industrial uses [4,5]. Attention in our laboratory has escalated regarding the potential of pyrimidine compounds and their complexes [6][7][8][9][10][11][12][13][14][15][16][17][18]. Owing to the role played by these complexes in many metabolic processes [19,20], their structure and stereochemistry is a matter of considerable interest.…”
