Abstract
Iron(II) and Ru(II) half-sandwich compounds encompass some promising pre-clinical anticancer agents whose efficacy may be tuned by structural modification of the coordinated ligands. Here, we combine two such bioactive metal centres in cationic bis(diphenylphosphino)alkane-bridged heterodinuclear [Fe2+, Ru2+] complexes to delineate how ligand structural variations modulate compound cytotoxicity. Specifically, Fe(II) complexes of the type [(η5-C5H5)Fe(CO)2(κ1-PPh2(CH2)nPPh2)]{PF6} (n = 1-5), compounds 1-5, and heterodinuclear [Fe2+, Ru2+] complexes, [(η5-C5H5)Fe(CO)2(μ-PPh2(CH2)nPPh2))(η6-p-cymene)RuCl2]{PF6} (n = 2-5) (compounds 7-10), were synthesized and characterised. The mononuclear complexes were moderately cytotoxic against two ovarian cancer cell lines (A2780 and cisplatin resistant A2780cis) with IC50 values ranging from 2.3 ± 0.5 μM to 9.0 ± 1.4 μM. For 7-10, the cytotoxicity increased with increasing Fe⋅⋅⋅Ru distance, consistent with their DNA affinity. UV-visible spectroscopy suggested the chloride ligands in heterodinuclear 8-10 undergo stepwise substitution by water on the timescale of the DNA interaction experiments, probably affording the species [RuCl(OH2)(η6-p-cymene)(PRPh2)]2+ and [Ru(OH)(OH2)(η6-p-cymene)(PRPh2)]2+ (where PRPh2 has R = [-(CH2)5PPh2-Fe(C5H5)(CO)2]+). One interpretation of the combined DNA-interaction and kinetic data is that the mono(aqua) complex may interact with dsDNA through nucleobase coordination. Heterodinuclear 10 reacts with glutathione (GSH) to form stable mono- and bis(thiolate) adducts, 10-SG and 10-SG2, with no evidence of metal ion reduction (k1 = 1.07 ± 0.17 × 10-1 min-1 and k2 = 6.04 ± 0.59 × 10-3 min-1 at 37 °C). This work highlights the synergistic effect of the Fe2+/Ru2+ centres on both the cytotoxicity and biomolecular interactions of the present heterodinuclear complexes.

Abstract
The synthesis and characterization of chiral pincer-ruthenium complexes of the type (R2NNN)RuCl2 (PPh3) (R = 3-methylbutyl and 3,3-dimethylbutyl) is reported here. The cytotoxicity studies of these complexes were studied and compared with the corresponding activity of achiral complexes. The cytotoxic effect of pincer-ruthenium complexes on human dermal fibroblasts and human tongue carcinoma cells assessed using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay displayed an inhibition of normal and cancer cell growth in a dose-dependent manner. Intracellular reactive oxygen species (ROS) level measurement, lactate dehydrogenase assay, DNA fragmentation, and necrosis studies revealed that treatment with pincer-ruthenium complexes induced a redox imbalance in SAS cells by upregulating ROS generation and caused necrotic cell death by disrupting the cellular membrane integrity.

Abstract
A series of new organometallic carbosilane dendrimers (first and second generation) and the corresponding non-dendritic mononuclear based on ruthenium arene fragments are described. The metallodendrimers were prepared by reactions of the precursor [Ru(η(6)-p-cymene)Cl2]2 with carbosilane dendrimers functionalized with N-donor monodentate ligands such as NH2- and pyridine, or with N,O-, N,N-chelating imine ligands. While the dendrimer precursors are insoluble in DMSO or water, novel metallodendrimers are soluble in DMSO and some of them are even highly soluble in water. The molecular structure of the "Ru-NH2" mononuclear compound (zero generation) was determined by single-crystal X-ray crystallography. The cytotoxicity activity of these dendritic structures was evaluated in several human cancer cell lines and compared with that of the corresponding mononuclear ruthenium complexes. Most compounds display significant cytotoxic activities in the low micromolar range with the first generation ruthenium dendrimers being the most active compounds. The cell death type for selected compounds has been studied as well as their reactivity towards relevant biomolecules such as DNA, Human Serum Albumin (HSA) and Cathepsin-B. All the data point to a mode of action different from that of cisplatin for most complexes. First generation ruthenium dendrimers inhibit Cathepsin-B, which may suggest potential antimetastatic properties of these compounds.

Abstract
![]()
A series
of organometallic ruthenium(II) complexes containing iminophosphorane
ligands have been synthesized and characterized. Cationic compounds
with chloride as counterion are soluble in water (70–100 mg/mL).
Most compounds (especially highly water-soluble 2) are
more cytotoxic to a number of human cancer cell lines than cisplatin.
Initial mechanistic studies indicate that the cell death type for
these compounds is mainly through canonical or caspase-dependent apoptosis,
nondependent on p53, and that the compounds do not interact with DNA
or inhibit protease cathepsin B. In vivo experiments of 2 on MDA-MB-231 xenografts in NOD.CB17-Prkdc SCID/J mice showed an
impressive tumor reduction (shrinkage) of 56% after 28 days of treatment
(14 doses of 5 mg/kg every other day) with low systemic toxicity.
Pharmacokinetic studies showed a quick absorption of 2 in plasma with preferential accumulation in the breast tumor tissues
when compared to kidney and liver, which may explain its high efficacy
in vivo.

Abstract
The interaction between bifenthrin (BF) and calf thymus DNA (ctDNA) in physiological buffer (pH 7.4) was investigated by UV-vis absorption, fluorescence, circular dichroism (CD), and Fourier transform infrared (FT-IR) spectroscopy, coupled with viscosity measurements and molecular docking techniques. It was found that BF molecular could intercalate into the base pairs of ctDNA as evidenced by significant increases in absorption intensity, fluorescence polarization and relative viscosity of ctDNA, decrease in iodide quenching effect, and induced CD spectral changes. The association constant of BF with ctDNA was evaluated to be in the order of 10(4) L mol(-1). Thermodynamic analysis of the binding data obtained at different temperatures suggested that the binding process was primarily driven by hydrogen bonds and van der Waals forces, as the values of the enthalpy change (ΔH) and the entropy change (ΔS) were calculated to be -31.13±1.89 kJ mol(-1) and -22.79±1.21 J mol(-1) K(-1), respectively. The results of FT-IR spectra and molecular docking showed that a specific binding mainly existed between BF and adenine and guanine bases.

Abstract
The binding of permethrin (PE) with calf thymus DNA (ctDNA) in physiological buffer (pH 7.4) was investigated by ultraviolet-visible (UV-vis) absorption, fluorescence, circular dichroism (CD), and Fourier transform infrared (FT-IR) spectroscopy merging with multivariate curve resolution-alternating least-squares (MCR-ALS) chemometrics approach. The MCR-ALS was applied to resolve the combined spectroscopic data matrix, which was obtained by UV-vis and fluorescence methods. The concentration profiles of PE, ctDNA, and PE-ctDNA complex and their pure spectra were then successfully obtained. The PE molecular was found to be able to intercalate into the base pairs of ctDNA as evidenced by decreases in resonance light-scattering signal and iodide-quenching effect and increase in ctDNA viscosity. The results of FT-IR spectra indicated that PE was prone to bind to G-C base pairs of ctDNA, and the molecular docking studies were used to validate and clarify the specific binding. The observed changes in CD signals revealed that the DNA turned into a more highly wound form of B-conformation. The calculated thermodynamic parameters, enthalpy change (ΔH°) and entropy change (ΔS°), suggested that hydrogen bonds and van der Waals forces played a predominant role in the binding of PE to ctDNA.
