Abstract
Background To overcome cisplatin resistance, the cytotoxicity of a novel antitumor agent on two ovarian cancer cell lines sensitive and resistant to cisplatin was investigated. Methods MTT assay and flow cytometry were performed to assess the cytotoxicity of a novel water-soluble Pd (II) complex, [Pd(bpy)(pyr-dtc)]NO3 (PBPD), on cisplatin-sensitive and cisplatin-resistant ovarian cancer cell lines. Furthermore, variations in the expression of drug resistance gene cluster of differentiation 99 (CD99), signal transducer and activator of transcription 3 (STAT3), octamer-binding transcription factor 4 (OCT4), and multidrug resistance mutation 1 (MDR1) were evaluated using Real-Time PCR. Results The IC50 values of PBPD in resistant cells were higher than those in sensitive cells. Furthermore, PBPD has a deadlier effect on sensitive cells compared to resistant cells, and the cell survival rate is reduced over time. Flow cytometry revealed that PBPD enhanced the population of living-resistant cells while driving them to apoptosis. PBPD, on the other hand, has a greater effect on the living cell population and has dramatically shifted the population toward apoptosis and necrosis in the sensitive cells. Furthermore, gene expression analysis showed that when sensitive and resistant cells were treated with cisplatin, all resistance genes increased significantly relative to the control. In contrast to OCT4, MDR1, STAT3, and CD99 resistance genes were not significantly elevated in sensitive cells treated with PBPD compared to the control. Thus, the expression of resistance genes in resistant cells treated with PBPD was lower than cisplatin. Conclusions As a result, PBPD is a promising anticancer agent for CDDP-resistant ovarian cancer.

Astaxanthin (ATX) is a natural xanthophyll carotenoid with antioxidant, anti-inflammatory, and anti-apoptotic properties that has been used in the prevention and treatment of some cancers.
Objectives:
In the present study, the antioxidant effect of beta-lactoglobulin (β-LG) nanocapsules containing ATX and 5-fluorouracil (5-FU; the first-line therapy for colorectal cancer) on the antioxidant enzymes activity of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX) in HCT116 colorectal cancer cell line was examined.

Methods:
In this experimental study, HCT116 cells were treated with different treatments of encapsulation of ATX in β-LG, encapsulation 5-FU in β-LG, co-encapsulation of ATX and 5-FU in β-LG, free ATX, free 5-FU, free ATX and free 5-FU, or β-LG nanocapsules without drugs for 24, 48 and 72 hours. There is a control group in which HCT116 cells were not treated with any drug. Then, 50% inhibitory concentration (IC50) and cell viability were determined using an MTT assay. The antioxidant enzyme activity of SOD, CAT, and GPX was measured by a colorimetric method in HCT116 cells.

The antioxidant enzyme activity of SOD, CAT and GPX was measured by colorimetric methods in HCT116 cells.
Results:
Different treatments reduced the cell viability and increased apoptotic cells in a time-dependent manner, which was significant for beta-lactoglobulin nanocapsules treatment (P<0.05). It means receiving more 5-FU or ATX in the encapsulated form by HCT116 cells. The antioxidant enzyme activity of SOD, CAT, and GPX in HCT116 cells treated with beta-lactoglobulin nanocapsule treatment significantly increased compared to the control group (P<0.001). Moreover, the antioxidant activity of these enzymes in different treatments containing ATX (free or encapsulation) was significantly higher than in other treatments (P<0.05). The most increase in the activity of antioxidant enzymes is recorded in the treatment of nanocapsules containing ATX and 5-FU simultaneously.

Different treatments reduced the cell viability and increased apoptotic cells in a time-dependent manner, which this reduction was significant for beta-lactoglobulin nanocapsules treatments (P&amp;amp;amp;lt;0.05). It means receiving more 5-FU or ATX in encapsulated form by HCT116 cells. The antioxidant enzymes activity of SOD, CAT and GPX in HCT116 cells treated with beta-lactoglobulin nanocapsules treatments significantly increased compared to the control group (P&amp;amp;amp;lt;0.001). Also, the antioxidant activity of these enzymes in different treatments containing ATX (free or encapsulation) was significantly higher than other treatments (P&amp;amp;amp;lt;0.05). The most increase in the activity of antioxidant enzymes is recorded in the treatment of nanocapsules containing ATX and 5-FU simultaneously.
Conclusion:
Increased activity of antioxidant enzymes in addition to the induction of apoptosis in colorectal cancer cells by various treatments of beta-lactoglobulin nanocapsules indicates more effective drug administration in encapsulated form as well as synergistic thera[peutic effects of ATX and 5-FU. Moreover, the main increase in antioxidant enzyme activity may be related to ATX.

Abstract
Novel studies have shown neurological treatment possibilities with extracellular vesicles (EVs) as natural particles with a special composition that are produced by different cell types. Their stability, natural structure, composition, and bioavailability make them good candidates as drug vehicles. Here, EVs were isolated from amniotic fluid (AF) through differential centrifugation, and characterized for size (<200 nm), structure, and composition, their effectiveness on the human PC12 cell line, and brain of chick embryos exposed to sodium valproate (animal autistic model). Sulforaphane (SFN) was employed as a bioactive compound and then encapsulated into Evs using three methods including passive (incubation), active (sonication), and active-passive (sonication-incubation). Further, the loading and in vitro releases of SFN fitted the Korsmeyer-Peppas (R2 = 0.99) kinetic model by non-Fickian diffusion case II (n = 0.44, passive loading) and Fickian diffusion case I (n = 0.41, active and active-passive loading). SFN-loaded EVs (SFN@EVs; 11 μM: 103 nM) stimulated hPC-12 cell proliferation. The gene expression analysis revealed that SFN@EVs could upregulate Nrf2 and reduce IL-6 expression. Eventually, histopathological results of the coronal cross-section of the chick embryos brain showed treatment with SFN@EVs. This treatment illustrated normality in the gray and white matter and the orientation of the bipolar neurons. Our findings showed EVs' potentially acting as a gene expression regulator in autism spectrum disorder.

Abstract
Two novel palladium(II)-amino acid complexes, [Pd(Ala)2]·H2O (PA) and [Pd(Val)2].H2O (PV) (Ala = alanine; Val = valine) were synthesized and characterized through FTIR, UV/Vis, 1H-NMR spectroscopies, CHN analysis, X-ray crystallography and molar conductivity measurement. Furthermore, cytotoxicity of Pd(II) complexes against human leukemia cancer cell line, MOLT4 showed promising cancer cell death (CC50 = 0.71 ± 0.046 µM for PA; CC50 = 0.85 ± 0.063 µM for PV) that were less than cisplatin (1.59 ± 0.25 µM). Moreover, the interaction of both the complexes with DNA and BSA was studied using UV-Vis absorption and emission spectroscopic techniques that demonstrated the bindings occurred via van der Waals forces and hydrogen bond. Furthermore, the fluorescence titration showed that static quenching mechanism plays predominate role in binding process. All results showed that both complexes have more binding tendency to DNA in compared to BSA that can be a significant achievement for further medical purposes as a potential antitumor candidate. Finally, molecular docking simulation was performed for PA and PV complexes with DNA and BSA and demonstrated both complexes bind to the groove of DNA mainly by hydrogen bond and interact with site I of BSA via hydrogen bond as well.

Abstract
A family of organonickel complexes has been prepared, fully characterized, and tested for their antiproliferative activity against estrogen-responsive human breast cancer cells (MCF7). The three SCS-type pincer ligands HL1, HL2, and HL3 and their corresponding Ni(ii) complexes NiL1, NiL2, and NiL3 have been synthesized and fully characterized, including by single crystal diffraction studies for the complexes. The complexes possess square planar geometry with two symmetrical 5-membered nickellacycles. Fluorescence spectroscopy, circular dichroism measurements, molecular modeling, colorimetric based assay and tumor transplantation studies were used to evaluate the protein binding and antiproliferative activities of these organometallic complexes both in vitro and in vivo. Fluorescence quenching was used to investigate bovine serum albumin (BSA) interaction at different temperatures (293, 303 and 313 K), and the results were analyzed using the classical Stern-Volmer equation, allowing us to propose a dynamic quenching mechanism. Studies in vitro on the antiproliferative activity of the three organonickel complexes against estrogen-responsive human breast cancer cells (MCF7) showed promising antitumor activity for NiL1 containing pyrrolidine fragments. In vivo administration of this compound significantly inhibits tumor growth in estrogen-dependent MC4L2 cancer cells in female BALB/c mice.

Abstract
Two novel, neutral and water soluble Pd(II) complexes of formula [Pd(Gly)(Ala)] (1) and [Pd(Gly)(Val)] (2) (Gly, Ala, and Val are anionic forms of glycine, alanine, and valine amino acids, respectively) have been synthesized and characterized by FT-IR, UV-Vis, 1H-NMR, elemental analysis, and molar conductivity measurement. The data revealed that each amino acid binds to Pd(II) through the nitrogen of -NH2 and the oxygen of -COO- groups and acts as a bidentate chelate. These complexes have been assayed against leukemia cells (K562) using MTT method. The results indicated that both of the complexes display more cytotoxicity than the well-known anticancer drug, cisplatin. The interaction of the compounds with calf thymus DNA (CT-DNA) and human serum albumin (HSA) were assayed by a series of experimental techniques including electronic absorption, fluorescence, viscometry, gel electrophoresis, and FT-IR. The results indicated that the two complexes have interesting binding propensities toward CT-DNA as well as HSA and the binding affinity of (1) is more than (2). The fluorescence data indicated that both complexes strongly quench the fluorescence of ethidium bromide-DNA system as well as the intrinsic fluorescence of HSA via static quenching procedures. The thermodynamic parameters (ΔH°, ΔS°, and ΔG°) calculated from the fluorescence studies showed that hydrogen bonds and van der Waals interactions play a major role in the binding of the complexes to DNA and HSA. We suggest that both of the Pd(II) complexes exhibit the groove binding mode with CT-DNA and interact with the main binding pocket of HSA. Communicated by Ramaswamy H. Sarma.

Abstract
The aim of this study was to examine the interaction of [Pd(2,2'-bipyridine) (morpholinedithiocarbamate)]NO3 and [Pt (2,2'-bipyridine)(morpholinedithiocarbamate)]NO3 with human serum albumin under physiological conditions by using fluorescence, absorption, and circular dichroism spectroscopic techniques. Spectroscopic analysis of the emission quenching at different temperatures demonstrated that the quenching mechanism was static quenching. From the circular dichroism results, thermal stability study, it was found that the interaction of the complexes with human serum albumin caused a conformational change of the protein reversibly. These 2 anticancer Pd and Pt complexes were activated against chronic myelogenous leukemia cell line K562, so that 50% cytotoxic concentration values of 16 and 26 μM for Pd and Pt complexes, respectively, were observed, which were much lower than that of cisplatin (154 μM). Biological activities of both Pd and Pt complexes were also assayed against selective microorganisms by the disc diffusion method. These results showed that the Pd(II) complex is antifungal agent but Pt(II) complex has antibacterial activity. Also, the interaction of both metal derivative complexes was studied by molecular docking. Complementary molecular docking results may be useful to determine the binding mechanism of human serum albumin in pharmaceutical and biophysical studies providing new insight in the novel pharmacology.

Abstract
Over the past few years, there have been several attempts to deliver anticancer drugs into the body. It has been shown that compared to other available carriers, colloidal gelatin nanoparticles (CGNPs) have distinct properties due to their exceptional physico-chemical and biological characteristics. In this study, a novel water-soluble palladium (II) anticancer complex was first synthesised, and then loaded into CGNPs. The CGNPs were synthesised through a two-step desolvation method with an average particle size of 378 nm. After confirming the stability of the drug in the nanoparticles, the drug-loaded CGNPs were tested for in vitro cytotoxicity against human breast cancer cells. The results showed that the average drug encapsulating efficiency and drug loading of CGNPs were 64 and 10 ± 2.1% (w/w), respectively. There was a slight shift to higher values of cumulative release, when the samples were tested in lower pH values. In addition, the in vitro cytotoxicity test indicated that the number of growing cells significantly decreased after 48 h in the presence of different concentrations of drug. The results also demonstrated that the released drug could bind to DNA by a static mechanism at low concentrations (0.57 µM) on the basis of hydrophobic and hydrogen binding interactions.

Abstract
In this study, a cytotoxic Pt(IV) complex [Pt(5,5'-dmbpy)Cl4 (5,5'-dmbpy is 5,5'-dimethyl-2,2'-bipyridine) was selected to investigate its affinity to human serum albumin (HSA) by spectroscopy and molecular docking methods. This complex has a bidentate nitrogen donor ligand with four chloride anions attached to a Pt(IV) metal in a distorted octahedral environment. The fluorescence data showed this complex quench the intrinsic fluorescence of HSA through a static quenching mechanism. The binding constant (Kb) and the number of binding sites (n) were obtained based on the results of fluorescence measurements. UV-vis, circular dichroism spectroscopy, and three-dimensional fluorescence spectroscopy proved that the Pt(IV) complex could slightly change the secondary structure of protein. Thermodynamic parameters show that the Pt(IV) complex binds to HSA through electrostatic and Vander Waals interactions with one binding site. The molecular docking results confirmed the spectroscopic results and showed that Pt(IV) complex is embedded into subdomain IIA of protein. The aim of this study is to describe the performance of effective anti-cancer drugs when faced with proteins such as HSA.

Abstract
The interaction between [Pd(But-dtc)(phen)]NO3 (where But-dtc = butyldithiocarbamate and phen = 1,10-phenanthroline) with HSA (Human Serum Albumin) was investigated by applying fluorescence, UV-Vis and circular dichroism techniques under physiological conditions. The results of fluorescence spectra indicated that the Pd(II) complex could effectively quench the fluorescence intensity of HSA molecules via static mechanism. The number of binding sites and binding constant of HSA-Pd(II) complex were calculated. Analysis of absorption titration data on the interaction between Pd(II) complex and HSA revealed the formation of HSA-Pd(II) complex with high-binding affinity. Thermodynamic parameters indicated that hydrophobic forces play a major role in this interaction. Furthermore, CD measurements were taken to explore changes in HSA secondary structure induced by the Pd(II) complex.

Abstract
A new anionic 8-hydroxyquinolinatopalladate(II) complex with malonate has been synthesized and characterized by elemental analysis, conductivity, FT-IR, UV-Vis and 1H NMR techniques to enhance the development of potential anticancer agents. Cytotoxicity was determined against the human leukemia cells, molt, by MTT assay. The novel antitumor Pd(II) complex was evaluated for its binding to calf thymus DNA (ctDNA) in physiological buffer (pH 7.0) by using absorption spectroscopy, fluorescence titration spectra, ethidium bromide displacement and gel chromatography studies. The results obtained from these analyses indicated that the water-soluble complex can bind to DNA cooperatively through a static quenching procedure at low concentrations. Thermodynamic parameters obtained from fluorescence experiments at different temperatures revealed the hydrogen binding and van der Waals force in the binding process which was supported by Scatchard's plots.

Abstract
A new water-soluble palladium(II) complex, [Pd(bpy)(pyr-Ac]NO₃ in which bpy = 2,2'-bipyridine and pyr-Ac is 1-pyrrolacetato, has been synthesized and characterized by spectroscopic methods (¹H NMR, FT-IR, and UV-Vis), molar conductivity measurements, and elemental analysis. The results obtained from elemental analysis and conductivity measurements confirmed the stoichiometry of ligand and its complex while the characteristic peaks in UV-Vis and FT-IR and resonance peaks in (¹H NMR spectra confirmed the formation of ligand frameworks around the palladium ion. The 50% cytotoxic concentration (Ic₅₀) of new synthesized Pd(II) complex was determined by using MTT assay against human breast cancer cell line, T47D. The interaction between the Pd(II) complex with calf thymus DNA was studied at different temperatures by using absorption spectroscopy, fluorescence titration spectra, ethidium bromide displacement, and gel chromatography studies. The results obtained by absorption spectroscopy revealed that the Pd(II) complex can bind to DNA cooperatively at low concentrations. Several binding parameters in the above interaction were calculated by the fluorescence quenching method. The quenching mechanism was suggested to be the static quenching. The thermodynamic parameters: enthalpy change (ΔH °), entropy change (ΔS °), and Gibbs free energy (ΔG °), showed that van der Waals and hydrogen binding are predominant intermolecular forces between Pd(II) complex and DNA. These results were also consistent with the results obtained from Scatchard's plots.

Abstract
The interaction of new 1, 10-phenanthrolineoctyldithiocarbamatopalladium (II) nitrate with DNA from calf thymus was investigated at 300 and 310 K in a Tris-HCl buffer of pH 7.0 medium containing 20 mM sodium chloride. This water soluble, square planar Pd(II) complex has been synthesized and spectroscopic (electronic, infrared, and nuclear magnetic resonance) and elemental analysis of the complex are discussed. This complex shows greater growth inhibitory activity against human tumor cell line K562 than cisplatin. Results of UV-visible studies show that the complex exhibits cooperative binding with DNA and denatures the DNA at an extremely low concentration (∼11.98 μM). Fluorescence studies reveal that the mode of binding of this complex with DNA seems to be intercalation. The results of sephadex G-25 column show that the binding of metal complex with DNA is so strong that it does not readily break. Several binding and thermodynamic parameters are also described. They may shed light on the mechanisms of interaction of this agent with DNA, which should be quite different from that of cisplatin.

Abstract
A novel palladium(II) complex has been synthesized with hexyldithiocarbamate (Hex-dtc) and 1,10-phenanthroline (phen) by the reaction of [Pd(phen)(H(2)O)(2)](NO(3))(2) with sodium salt of hexyldithiocarbamate and a complex of type [Pd(Hex-dtc) (phen)]NO(3) has been obtained. The complex has been characterized by elemental analysis, molar conductance, (1)H NMR, IR and electronic spectroscopic studies. The dithiocarbamate ligand acts in bidentate fashion. This water-soluble complex was screened against chronic myelogenous leukemia cell line, K562, for cytotoxic effects and showed significant antitumor activity much lower than that of cisplatin. The interaction of this complex with calf thymus DNA (ctDNA) was extensively investigated by a variety of spectroscopic techniques. Absorbance titration experiments imply the interaction of 4 Pd(II) complex molecules per 1000 nucleotides on DNA with positive cooperativity in the binding process and the complex denature the DNA at very low concentration (~14.3 µM). Fluorescence titration spectra and fluorescence Scatchard plots suggest that the Pd(II) complex intercalate in DNA. The gel chromatograms obtained from Sephadex G-25 column experiments showed that the binding of metal complex with DNA is so strong that it does not readily break. Furthermore, some thermodynamic and binding parameters found in the process of UV-Visible studies are described. They may provide specificity of the compound with ctDNA.

Abstract
The interaction of calf thymus DNA (CT-DNA) with a novel synthesized and characterized Palladium (II) complex with the formula of [Pd (Et-dtc) (phen)] NO(3) (where phen is 1,10-phenanthroline and Et-dtc is ethyldithiocarbamate) was extensively studied by various spectroscopic techniques. UV-vis studies imply that there is a set of 6 binding sites for the complex on DNA with positive cooperativity in the binding process. This complex unexpectedly denatures the DNA at very low concentration (approximately 9.8 microM). Gel filtration studies indicate that the binding of metal complex with DNA is strong enough not to readily break. Fluorescence studies show that the palladium complex intercalates in DNA through the planar 1,10-phenanthroline ligand presented in its structure. Several binding and thermodynamic parameters are also described. Furthermore, anti-tumor studies of this water soluble complex against human cell tumor lines (K562) have been done. It shows 50% cytotoxic concentration (Ic(50)) value much lower than that of cisplatin.
