Повний текст джерелаDesign of Vanadium Antidiabetic Agents: Development and Recent AdvancesThe discovery of the enhanced hypoglycemic activity of bis(maltolate)oxovanadiu m (IV) (BMOV) compared to simplevanadium salts stimulated the design, synthesis and both in vitro and in vivo evaluation of a large variety of oxovanadium (IV)complexes with different organic ligands for their potential use as antidiabetic drugs that may be able to substitute, either partially or totally, the daily insulin injections used in the treatment of type 1 diabetes mellitus or the orally available hypoglycemic drugs usually used in combined therapy for type 2 diabetes.Recently, a close BMOV analogue, an ethyl substitute, has already successfully completed the phase 1 clinical trial in humans. The design of new types of complexes and the development of alternative delivery methods represent an active research field today.

Повний текст джерелаCucurbiturils are versatile molecules used in several branches of chemistry. These molecular cages form a family of homologues from the condensation of glycoluril and formaldehyde in acidic medium. Their applications range from catalysis, photochemistry, organic and inorganic synthesis, materials and supramolecular chemistry. Particularly cucurbit[6]uril, or simply CB[6], is a very symmetrical molecule, which posesses coordination points on its portals, especially with hard acids. Due to this characteristic, it was possible to synthesize a new complex, with a vanadyl, VO2+, catalytic center bonded to the extremity of the cavitand. The access to the catalytic center of this molecule should be determined by the entrance of the substrate inside the macrocycle, which is limited by its volume and by solvophobicity, because the cavity is strongly hydrophobic. The structure of this new complex could not be completely solved yet, because it was impossible to obtain a single crystal for X-rays diffraction analysis. The solid state characterization techniques indicated that this new complex has its metallic center in a rectangular-base pyramid configuration. This was shown by the spectroscopic evidences which point to a d1 ion in a C2V symmetry. Attempts were made to synthesize both mono and binuclear species, but all the techniques we have used have demonstrated that only the former one was obtained. The first catalytic tests for hydrocarbons convertion in mild conditions have shown good results towards for linear substrates and no activity at all towards more volumous cyclic molecules. The results we have obtained indicate that the alkane oxidation reactions with these complexes occur inside the cavity along the (V=O)2+ ion dz2 orbital , and not on its superior moiety on the vanadyl oxygen atom.

A series of chiral oxovanadium(IV) complexes derived from tridentate N-3,5-substituted and N-3,4-benzo- and N-5,6-benzo-salicylidene-α-amino acids can serve as efficient catalysts for the enantioselective oxidative couplings of various 3-,6-,7-substituted- 2-naphthols under O2. We take the reseach about the solvent effect,cooxidant effect,amino acid effect….and so on in detail. Our catalyst in the coupling reaction of 2-naphthol is the best methodology as we know. The best scenario involves the use of a vanadyl complex arising from 2-hydroxy-1-naphtholaldehyde and valine (or phenylalanine) in CCl4, leading to BINOLs in good yields (75-100%) and with enantioselectivities of up to 68%.

Повний текст джерелаA range of oxobis(phenyl‐1,3‐butanedione) vanadium(IV) complexes have been successfully synthesized from cheap starting materials and a simple and solvent‐free one‐pot dry‐melt reaction. This direct, straightforward, fast and alternative approach to inorganic synthesis has the potential for a wide range of applications. Analytical studies confirm their successful synthesis, purity and solid‐state coordination, and we report the complexes’ uses as potential drug candidates for the treatment of cancer. After a 24‐hour incubation of A549 lung carcinoma cells with the compounds, they reveal cytotoxicity values 11‐fold greater than cisplatin, and remain non‐toxic towards normal cell types. Additionally, the complexes are stable over a range of physiological pH values and show the potential for interactions with BSA.
