Abstract
Many transition metal complexes have been explored for their therapeutic properties after the discovery of cisplatin. Schiff bases have an efficient complexation tendency with the transition metals and several medicinal properties have been reported. However, fewer studies have reported the medicinal utility of vanadium and its Schiff base complexes. This paper provides a comprehensive overview of vanadium complexes with Schiff bases along with their mechanistic insight. Vanadium complexes in + 4 and + 5 oxidation states have exhibited well-defined geometry and found to be thermodynamically stable. The studies have reported the G0/G1 phase cell cycle arrest and decreased delta psi m, inducing mitochondrial membrane depolarization in cancer cell lines along with the alterations in the metabolism of the cancer cells upon dosing with the vanadium complexes. Cancer cell invasion and growth are also found to be markedly reduced by peroxo complexes of vanadium. The studies included in the review paper have been taken from leading indexing databases and focus was laid on recent reports in literature. The biological potential of vanadium complexes of Schiff bases opens new horizons for future interdisciplinary studies and investigation focussed on understanding the biochemistry of these complexes, along with designing new complexes which have better bioavailability, solubility and low or non-toxicity.

Abstract
Compounds containing heavy metals such as vanadium, nickel, and cobalt may be useful for the treatment of various diseases. Multiple studies have been carried out on the anticancer effects of vanadium-contained compounds on different cell types. This study aimed to evaluate the role of schiff base oxovanadium complex ([N,N'-bis(3-methoxy-salicylidene)-1,2-phenylenediamine]Vanadium(IV) Oxide Complex) on cell cycle arrest and different cell cycle phases in MKN45 cell of gastric cancer. Schiff base oxovanadium complex was used to assessthe amount of cytotoxicity via cell viability test. PI color and flow cytometry technique were applied to evaluate the effects of vanadium synthetic compounds on cell cycle phases; subsequently, we analyzed the change rates of gene expression in P53, GADD45, and CDC25 genes, which are involved in cell division phases. The findings indicated that the vital activities of time-dependent and concentration-dependent MKN45 cells with schiff base oxovanadium complex were significantly reduced; therefore, this complex is able to inhibit the migration of cancer cells and metastatic activities in a time-dependent mode. Cell cycle arrest was obtained after 48 h of treatment in phase G2/M at 1 microgram/milliliter (μg/ml) concentration. This is probably attributed to the increased gene expression of P53 and GADD45 genes and reduced gene expression of CDC25 gene. Compounds containing such heavy metals as vanadium decrease the growth, proliferation, and migration of MKN45 cells. They arrest cell cycle in phase G2/M via changing the controllers of cell division phases activated due to DNA damage.

Abstract
Vanadium salts and coordination compounds have desirable cellular anticancer effects, and although they have been investigated in detail as a potential treatment for diabetes, less attention has been given to the anticancer effects. The inhibition of some signal transduction enzymes is known, and studies of the metabolism and activation pathways both in vitro and in vivo are important for future investigations and development of vanadium's role as a new potential drug. In addition, a new approach has demonstrated that the enhancement of oncolytic viruses using vanadium salts and coordination complexes for immunotherapy is very promising. Some differences exist between this approach and current antidiabetic and anticancer studies because vanadium(iv) complexes have been found to be most potent in the latter approach, but the few compounds investigated with oncolytic viruses show that vanadium(v) systems are more effective. We conclude that recent studies demonstrate effects on signal transduction enzymes and anticancer pathways, thus suggesting potential applications of vanadium as anticancer agents in the future both as standalone treatments as well as combination therapies.

Abstract
Phosphotyrosine signaling is regulated by the opposing actions of protein tyrosine kinases (PTKs) and protein tyrosine phosphatases (PTPs). Here we discuss the potential of vanadium derivatives as PTP enzyme inhibitors and metallotherapeutics. We describe how vanadate in the V oxidized state is thought to inhibit PTPs, thus acting as a pan-inhibitor of this enzyme superfamily. We discuss recent developments in the biological and biochemical actions of more complex vanadium derivatives, including decavanadate and in particular the growing number of oxidovanadium compounds with organic ligands. Pre-clinical studies involving these compounds are discussed in the anti-diabetic and anti-cancer contexts. Although in many cases PTP inhibition has been implicated, it is also clear that many such compounds have further biochemical effects in cells. There also remain concerns surrounding off-target toxicities and long-term use of vanadium compounds in vivo in humans, hindering their progress through clinical trials. Despite these current misgivings, interest in these chemicals continues and many believe they could still have therapeutic potential. If so, we argue that this field would benefit from greater focus on improving the delivery and tissue targeting of vanadium compounds in order to minimize off-target toxicities. This may then harness their full therapeutic potential.

Abstract
Diverse biological activities of vanadium(V) drugs mainly arise from their abilities to inhibit phosphatase enzymes and to alter cell signaling. Initial interest focused on anti-diabetic activities but has shifted to anti-cancer and anti-parasitic drugs. V-based anti-diabetics are pro-drugs that release active components (e.g., H2 VO4- ) in biological media. By contrast, V anti-cancer drugs are generally assumed to enter cells intact; however, speciation studies indicate that nearly all drugs are likely to react in cell culture media during in vitro assays and the same would apply in vivo. The biological activities are due to VV and/or VIV reaction products with cell culture media, or the release of ligands (e.g., aromatic diimines, 8-hydroxyquinolines or thiosemicarbazones) that bind to essential metal ions in the media. Careful consideration of the stability and speciation of V complexes in cell culture media and in biological fluids is essential to design targeted V-based anti-cancer therapies.

Abstract
Walnut hull (wal hull) is an agricultural by-product that is widely used in traditional medicine for alleviating pain and treating skin diseases, however, recently it has gained much attention in modern pharmacology due to its antioxidant properties. The current study was aimed to determine the total phenolic, flavonoid, and tannin content of Persian wal hull extract and evaluate its biological effects on platelet function. Experimental data showed that acetone extract of wal hulls has a high content of polyphenolic compounds and antioxidant properties. The analytical study of crude extract by gas chromatography-mass spectrometry demonstrated different types of high- and low-molecular-weight compounds that are basically and biologically important. Moreover, an in vitro study revealed that wal hull extract at a concentration of 50 μg/mL inhibited thrombin-induced platelet aggregation and protein secretion by 50%, without any cytotoxic effects on platelets. The examined extract suppressed reactive oxygen species generation and also caspase activation in thrombin-stimulated platelets. Identically, N-acetylcysteine inhibited the increase of reactive oxygen species level induced by thrombin in platelets, and supported a link between cellular redox status and caspase activation in activated platelets. Presumably, the antiplatelet activity of wal hull extract is related to its polyphenolic compounds and their antioxidant properties. Therefore, wal hulls can be considered as a candidate for thrombotic disorders.

Abstract
Quantitative structure activity relationship (QSAR) for the anticancer activity of Fe(III)-salen and salen-like complexes was studied. The methods of density function theory (B3LYP/LANL2DZ) were used to optimize the structures. A pool of descriptors was calculated: 1497 theoretical descriptors and quantum-chemical parameters, shielding NMR, and electronic descriptors. The study of structure and activity relationship was performed with multiple linear regression (MLR) and artificial neural network (ANN). In nonlinear method, the adaptive neuro-fuzzy inference system (ANFIS) was applied in order to choose the most effective descriptors. The ANN-ANFIS model with high statistical significance (R2train = 0.99, RMSE = 0.138, and Q2LOO = 0.82) has better capability to predict the anticancer activity of the new compounds series of this family. Based on this study, anticancer activity of this compound is mainly dependent on the geometrical parameters, position, and the nature of the substituent of salen ligand.

Abstract
Vanadium compounds can exert anticancer effects, partly due to inhibition of tyrosine phosphatases. Here, we report the effect of N,N'-ethylenebis (pyridoxylideneiminato) vanadium (IV) complex (Pyr2 enV(IV)), that induced 93% and 57% of cell mortality in A375 (human melanoma) and A549 (human lung carcinoma) cells, respectively; the mortality was <24% in other cancer cell lines and in human normal epidermal keratinocytes, lung cells and peripheral blood mononuclear cells. The mechanism of Pyr2 enV(IV) effect relied on apoptosis induction; this was triggered by ROS increase, followed by mitochondrial membrane depolarization. Indeed, the addition of N-acetyl cysteine to cell cultures abated Pyr2 enV(IV)-induced apoptosis. These results disclose the pro-apoptotic activity of Pyr2 enV(IV) and its mechanism, relying on intracellular ROS increase.

Abstract
Alginate hydrogels possess tunable mechanical properties that can mimic soft marrow tissue and present three-dimensional (3D) cues. This study evaluates its utility for supporting leukemic cell growth in vitro and its impact on cell survival, growth, and differentiation. Our results showed that the standard viscosity alginates had compromised leukemia cell viability but lower viscosity alginates recovered cell viability and improved 3D cell proliferation (27 fold) compared to 2D cultures (18 fold). Conjugation with RGD peptides promoted further cell growth (43 folds). In general, 3D hydrogels supported high-density cultures better than 2D cultures. Leukemic cells formed densely packed cell clusters in alginate hydrogels and spontaneously differentiated into a more diverse myeloid population. The cell cycle data suggested that more cells go into active cycling with a G2/M arrest in alginate hydrogels and the presence of multiploidy confirmed maturation toward megakaryocytes. In summary, superior culture of leukemia cells in 3D hydrogels is demonstrated in this study accompanied by a potential role of physical cues influencing cell fate decision. Manipulation of biophysical and biochemical properties of alginate hydrogels permits the study of specific interactions and serves to provide a robust 3D platform for studying extrinsic contributions inside the bone marrow.

Abstract
The central V(V) atom in the title mononuclear oxovanadium complex, [VO(C(23)H(20)N(2)O(4))(CH(3)OH)]·H(2)O, has a distorted octahedral coordination. Two N atoms and two O atoms of the Schiff base define the base of the bipyramid and two O atoms are in the apical positions, one from vanadyl and the second from methanol. Density functional theory (DFT) calculations were performed for the title complex and its ligand to compare their geometry in the solid and gas phases. Additional analyses were made of the changes in the geometry of the ligand during complex formation. The HOMA (harmonic oscillator model of aromaticity) descriptor of π-electron delocalization was calculated to estimate the aromaticity of the benzene rings in the title complex and its ligand.

Abstract
Vanadium(V) oxo complexes with tetradentate diamine bis(phenolato) "salan" ligands of the type LVO(OiPr) (L is salan) with different steric and electronic substitutions at the ortho and para positions to the binding phenolato moiety were synthesized and their hydrolytic stability and cytotoxicity were analyzed. With one exception bearing large steric groups, all complexes examined displayed marked cytotoxic activity, comparable to, and often higher than, that of cisplatin. While the hydrolytic stability changed significantly depending on the substituent at the ortho position relative the O-donor with little effect of para substitutions, the cytotoxic activity largely was not affected, and high cytotoxicity was recorded also for relatively unstable complexes. Additional measurements revealed that the cytotoxicity is largely maintained following pre-incubation of up to 18 hours of the complexes in the biological medium prior to cell addition, suggesting that hydrolysis products might serve as the active species. In addition, appreciable cytotoxic activity was measured for an isolated hydrolysis product that was analyzed crystallographically to exhibit a dimeric structure with bridging oxo ligand where both metal centers are bound to the salan ligand, supporting the aforementioned conclusions.

Abstract
The green crystals of the title compound, [V(C(22)H(18)N(2)O(2))O], represent a mononuclear oxovanadium complex. The central V(IV) centre has a distorted square-pyramidal coordination. Two N atoms and two O atoms of the Schiff base ligand define the base of the pyramid, and the oxide O atom is in the apical position. Density functional theory (DFT) calculations were performed to analyse the changes in the geometry of the ligand during the complex formation. The most significant changes are observed in the values of the torsion angles in the vicinity of the donor N atoms. The HOMA index (Harmonic Oscillator Model of Aromaticity) has been calculated to compare the aromaticity of the benzene rings in the complex and its ligand.
