“…The result is totally in agreement with our recent ndings for a Cu(II) complex and others. [49][50][51] Furthermore, in the preliminary phase of another study, we also investigated the in vitro antitumor activity of the Ir(III) complex and two of the ligands towards A549, A2780 and A2780cis cells in comparison with cis-platin as reference. From the results, the studied complex shows considerably higher activity than free ligands and cis-platin (Table S7 and Fig.…”

“…On the other hand, all the complexes showed considerable shift in bands originating from amino NH stretching frequency as compared to free ligands [25]. In addition, in the IR spectra of the complexes, a new peak assigned to (M-N) appeared at ≈ 541 cm −1 , indicating formation of the Pt-N bond.…”

Platinum(II) complexes with carbazates and hydrazydes: Synthesis, spectral characterization, computational modeling, and biological studies, Polyhedron (2015), doi: http://dx. AbstractThis work reports on the synthesis and characterization of complexes of the type cis-[Pt(L) 2 X 2 ], where L = 4-methoxybenzylcarbazate (4-MC), benzyl carbazate (BC), 4-fluorophenoxyacetic acid hydrazide (4-FH), 3-methoxybenzoic acid hydrazide (3-MH), ethyl carbazate (EC), tert-butyl carbazate (TC), (4-hydroxy-phenyl)-acetic acid hydrazide (4-HH), and X = Cl -or I -.The structures of the platinum(II) complexes were optimized and theoretical data show good agreement with the experimental results, suggesting that the ligands are coordinated via the NH 2 groups. The cytotoxic activity of three representative compounds was evaluated in a chronic myelogenous leukemia cell line and health cell line from mouse (L929). The platinum complex with 4-fluorophenoxyacetic acid hydrazide was more active than the free ligand and carboplatin therefore it may be considered a promising antitumor agent. In addition, the platinum complexes with 4-methoxybenzylcarbazate (4-MC) and benzyl carbazate (BC) exhibited good activity. On the other hand, microbiological assays against Mycobacterium tuberculosis showed that all complexes and organic compounds are not very active.

“…The reactions were monitored at 560 nm with a UV/Vis spectrophotometer, and the rate of absorption change was determined. The percentage inhibition of NBT reduction was calculated using the following equation:, percentage inhibition of NBT reduction = (1 – k ′/ k ) × 100, where k ′ and k represent the slopes of the straight line of absorbance values as a function of time in the presence and absence of SOD mimic compound (SOD is superoxide dismutase), respectively.…”

Two aliphatic ether Schiff base lanthanide complexes (Ln = Eu, Ce) with bis(3‐methoxysalicylidene)‐3‐oxapentane‐1,5‐diamine (Bod), were synthesized and characterized by physicochemical and spectroscopic methods. [Eu(Bod)(NO3)3] (1) is a discrete mononuclear species and [Ce(Bod)(NO3)3DMF]∞ (2) exhibits an inorganic coordination polymer. In the two complexes, the metal ions both are ten‐coordinated and the geometric structure around the LnIII atom can be described as distorted hexadecahedron. Under excitation at room temperature, the red shift in the fluorescence band of the ligand in the complexes compared with that of the free ligand can be attributed to coordination of the rare earth ions to the ligand. Moreover, the antioxidant activities of the two complexes were investigated. The results demonstrated that the complexes have better scavenging activity than both the ligand and the usual antioxidants on the hydroxyl and superoxide radicals.
