Abstract
The use of schiff base complex against microbial agentes a has recently received more attention as a strategy to combat infections caused by multidrug-resistant bacteria and leishmania. This study aimed to evaluate the toxicity, antibacterial and leishmanicidal activities of the nickel (II) chloride schiff base complex ([Ni(L2)] against Leishmania amazonensis promastigote, multi-resistant bacterial strains and evaluate to modulate antibiotic activity against multi-resistant bacterial. The schiff base complex was characterized by the techniques of elemental analysis, Fourier transform infrared spectroscopy (FTIR), UV-vis absorption spectroscopy and thermal analysis (TGA/DTG/DSC). The [Ni(L2)] complex presented moderate toxicity in saline artemia (LC50 = 150.8 μg/mL). In leishmanicidal assay, the NiL2 complex showed values of IC50 of (6.079 μg/mL ± 0.05656 at the 24 h), (0.854 μg/mL ± 0.02474, 48 h) and (1.076 μg/mL ± 0.04039, 72 h). In antibacterial assay, the [Ni(L2)] complex presented significant inhibited the bacterial growth of P. aeruginosa (MIC = 256 μg/mL). However, [Ni(L2)] complex did not present clinically relevant minimum inhibitory concentration (MIC ≥1024 μg/mL) against S. aureus and E. coli. The combination of [Ni(L2)] complex and antibacterial drugs resulted in the increased antibiotic activity of gentamicin and amikacin against S. aureus and E.coli multi-resistant strains. Thus, our results showed that [Ni(L2)] complex is a promising molecule for the development of new therapies associated with aminoglycoside antibiotics and in disease control related to resistant bacteria and leishmaniasis.

Abstract
We report [RuII(L)(η6-p-cym)Cl] (1 and 2) and [PtII(L)(DMSO)Cl] (3 and 4) complexes, where L is a chelate imine ligand derived from chloroethylamine and salicylaldehyde (HL1) or o-vanillin (HL2). The complexes were characterized by single-crystal X-ray diffraction and other analytical techniques. The 1H nuclear magnetic resonance data show that both the Ru(II) and Pt(II) complexes start forming the aquated complex within an hour. The aquated complexes are stable at least up to 24 h. The complexes bind to the N7 of the model nucleobase 9-ethylguanine (9-EtG). Interaction with calf thymus (CT) DNA shows moderate binding interactions with binding constants, Kb (3.7 ± 1.2) × 103 M-1 and (4.3 ± 1.9) × 103 M-1 for 1 and 3, respectively. The complexes exhibit significant antiproliferative activity against human pancreas ductal adenocarcinoma (Mia PaCa-2), triple negative metastatic breast adenocarcinoma (MDA-MB-231), hepatocellular carcinoma (Hep G2), and colorectal adenocarcinoma (HT-29) cell lines. The studies show that with the same ligand the Pt(II) complexes are more potent than the Ru(II) complexes. The in vitro potencies of all the complexes toward pancreatic cancer cell line MIA PaCa-2 are more than cisplatin (CDDP). The Pt(II) and Ru(II) complexes show similar binding constants with CT-DNA, but the reactivity of the Pt(II) complex 3 with 9-EtG is faster and their overall cell killing pathways are different. This is evident from the arrest of the cell cycle by the Ru(II) complex 1 in the G2/M phase in contrast to the SubG1 phase arrest by the Pt(II) complex 3. The immunoblot study shows that 3 increases cyclin D and Bcl-2 expression in MDA-MB-231 due to the SubG1 phase arrest where these proteins express in greater quantities. However, both 1 and 3 kill in the apoptotic pathway via dose-dependent activation of caspase 3. Complex 3 depolarizes the mitochondria more efficiently than 1, suggesting its higher preference for the intrinsic pathway of apoptosis. Our work reveals that the same bidentate ligand with a change of the metal center, viz, Pt(II) or Ru(II), imparts significant variation in cytotoxic dosage and pathway of action due to specific intrinsic properties of a metal center (viz, coordination geometry, solution stability) manifested in a complex.

Abstract
Conformational analysis, molecular structure, relative stability, and complete vibrational assignment of bis(2,2,6,6-tetramethylheptane-3,5-dionato)copper(II), Cu(tmhd)2, were investigated by density functional theory (DFT), Natural Bond Orbital (NBO) theory and Atoms-in-Molecules (AIM) analysis. Fourier transform-Raman and IR spectra of this complex have been also recorded. The theoretical and experimental methods used to investigate the substitution effects of methyl groups by t-butyl (t-but) on the structure and stability of complex. To explore the substitution effects, the structure and vibrational spectra of Cu(tmhd)2 compared with copper(II) acetylacetonate, Cu(acac)2. A complete assignment of the observed band frequencies has been done. Comparing of observed and calculated vibrational spectra suggests coexisting of two conformers in the sample. All theoretical and vibrational spectroscopic results are consisting with a stronger metal-oxygen bond in Cu(tmhd)2 than in Cu(acac)2.
