using Coats–Redfern and Horowitz–Metzger methods. The ligands (HLn) and Ru(III) complexes are screened for their antimicrobial activity against bacterial and fungal species. The tested complexes (1) and (2) have good antibacterialactivity against Bacillus cereus and the tested ligands (HL2, HL3 and HL5) have good antifungal activity against Aspergillus niger and also HL5 showed against Alternaria alternata
制备5-(4-衍生物苯基偶氮)-8-羟基喹啉(HL n)的Ru(III)配合物,并通过元素分析,IR,UV-可见光谱,1 H和13 C NMR光谱,质谱,X表征射线衍射分析,电导率测量和磁化率测量以及热分析。X射线衍射图谱表明配体(HL 3)具有多晶性质和络合物(2)是完全无定形的。所述配体通过取代来自CN和OH基团的质子而充当通过CN和OH基团配位的二元双齿。摩尔电导率表明Ru(III)络合物本质上是非电解质。光谱表明,所有络合物都是八面体,其中两个氯化物附着在金属离子上。研究了配位体(HL n)和Ru(III)配合物的最佳键长,键角和计算的量子化学参数。分子对接用于预测偶氮染料配体与前列腺癌突变体2q7k激素受体之间的结合。活化热力学参数,例如活化能(E a),焓(ΔH⁎),熵(ΔS⁎))和吉布斯分解的自由能变化(ΔG⁎)是使用Coats–Redfern和Horowitz–Metzger方法计算的。筛选配体(HL
Molecular docking, potentiometric and thermodynamic studies of some azo quinoline compounds
(HL3) is polycrystalline nature. The proton-ligand dissociation constant of the azo compounds (HLn) and metal–ligandstabilityconstants of their complexes with metalions (Mn2 +, Co2 +, Ni2 + and Cu2 +) have been determined by potentiometric technique in 0.1 M KCl and 50% (by volume) DMF–water mixture. For the same ligand at constant temperature, the stabilityconstants of the formed complexes increase
This study presents the spectral and structure characteristics of seven azoquinoline dyes with different substituents and their new methylated counterparts for the first time, where some compounds are newly synthesized. The solvatochromic, tautomeric, halochromic, and dichroic behavior of the compounds were studied by electronic spectroscopy in various media. The different types of media were ordinary

transform infrared (FT-IR), proton nuclear magnetic resonance (1H NMR), molar conductance, magnetic measurements, thermal gravimetric and differential thermal analyses (TG and DTA), and electronic transition. The FT-IRspectra showed that the ligands are coordinated to the metal ions in a bidentate manner with donor sites of the azomethine-N and phenolic-OH. The FT-IR and UV–Visible spectra were compared
