Abstract:

Objective: Diabetes is complex metabolic disease having a symptom of hyperglycemia. Oxovanadium (IV) and l-amino acids are used to normalize the hyperglycemic condition. The aim of this study was to screen the α-amylase inhibitory activity of l-amino acids, their oxovanadium (IV) complexes, and electrochemical activity of oxovanadium (IV) complexes.Methods: All the oxovanadium (IV) complexes were synthesized according to the solubility of l-amino acids; the molar ratio of metal to l-amino acid was 1:2. The synthesized oxovanadium (IV) complexes were examined for their electrochemical behavior in 0.01 M sodium perchlorate solution. Further, the oxovanadium (IV) complexes of l-amino acids and l-amino acids were screened for their α-amylase inhibitory activity using spectrophotometric assay system.Results: The synthesized complexes were divided into four groups according to nature of amino acids. Entire complexes show simple irreversible wave for VO redox couples in −900–50 mV potential range and scan rate was 300 mV/S. All the complexes and l-amino acids were screened for their α-amylase inhibitory activity. L-Histidine and their oxovanadium (IV) complex show the minimum IC50 value, i.e. 4199.05 μM and 101.015 μM, respectively, in their respective groups.Conclusion: The data obtained from our study, it reveals that the entire oxovanadium (IV) complexes are an irreversible wave for VO redox system and the l-histidine and its oxovanadium (IV) complex is the most potent inhibitor for the α-amylase. Further, the complexes show minimum IC50 value on comparing their respective ligands due to the interaction of Vanadyl complex to the enzyme, at the sixth vacant position of Vanadyl complex.

Abstract:

We prepared [meso-tetrakis(4-carboxylatophenyl)porphyrinato]oxovanadium(IV) tetrasodium, ([VO(tcpp)]Na4), and investigated its in vitro insulin-mimetic activity and in vivo metallokinetic feature in healthy rats. The results were compared with those of previously proposed insulin-mimetic oxovanadium(IV)porphyrin complexes and oxovanadium(IV) sulphate. The in vitro insulin-mimetic activity and bioavailability of [VO(tcpp)]Na4 were considerably better than those of [meso-tetrakis (1-methylpyridinium-4-yl)porphyrinato]oxovanadium(IV)(4+) tetraperchlorate ([VO(tmpyp)](ClO4)4) and oxovanadium(IV) sulphate. On the other hand, [VO(tcpp)]Na4 and [meso-tetrakis(4-sulfonatophenyl) porphyrinato]oxidovanadate(IV)(4-)([VO(tpps)]) showed very similar in vitro insulin-mimetic activity and in vivo metallokinetic feature in healthy rats. In particular, the order of in vitro insulin-mimetic activity of the complexes was determined to be: [VO(tcpp)]Na4 ≈ [VO(tpps)] > ([VO(tmpyp)](ClO4)4 > oxovanadium(IV) sulphate.

Abstract:

With bidentate alkoxy alkoxide and alkoxy alcohol ligands, respectively, a series of oxovanadium complexes in the oxidation state +4 is synthesized starting from oxovanadium(V) compounds. The reaction of two or more equivalents of 2-methoxyethanol with VOCl3 in n-hexane yields a mixture of the monomeric oxovanadium(IV) complex cis-[VOCl2(HOCH2CH2OMe-κ2O)(HOCH2CH2OMe-κO1)] and the alkoxide-bridged oxovanadium(IV) dimer syn-[VOCl(µ-OCH2CH2OMe-κ2O)]2, which are separated by fractionated crystallization. The same reaction with 2-ethoxy- and 2-iso-propoxyethanol gives only the alkoxide-bridged oxovanadium(IV) dimers anti-[VOCl(µ-OCH2CH2OR-κ2O)]2 (R = Et, iPr). All alkoxide bridged oxovanadium(IV) dimers are furthermore obtained as decomposition products of the chloride-bridged oxovanadium(V) complexes [VO(µ-Cl)Cl(OCH2CH2OR-κ2O)]2 (R = Me, Et, iPr) by Cl2 elimination and react inversely with Cl2 to the vanadium(V) compounds.

Abstract:

The oxovanadium(IV) complexes LVO and L′VO (L = dianion of 5,14-dihydro-6,8,15.17- tetramethyldibenzo[b.i][1,4.8,11]tetraazacyclotetradecine. H2L, and L′ = dianion of 5,14-dihydro-6,15-dimethyl-8,17-diphenyldibenzo[b,i][1,4,8,11]tetraazacyclotetradecine, H2L′) are redox active as indicated by cyclovoltammetric measurements and confirmed by preparative methods: Reversible oxidation to the corresponding oxovanadium (V) cations is observed at ca. 0.35 V vs. SCE in CH2Cl2, and these cations are prepared in high yield by oxidation of the oxovanadium(IV) precursors with [(C5H5)2Fe]SbF6 (reversible by addition of cobaltocene). Irreversible reduction waves are observed for both complexes in the range -1 .9 to 2.1 V vs. SCE in CH2Cl2. Preparative reduction of LVO with Na/K alloy affords very unstable anionic oxovanadium(IV) complexes containing a deprotonated or reduced ligand, while with Li[B(C2H5)3H] in THF the Lewis acid/Lewis base adduct LVOxB(C2H3)3 is isolated. Spectroscopic data including ESR [vanadium(IV)] and 51V NMR [vanadium(V)] are given and discussed. The complexes LVO and [LVO]SbF6 have been characterized by single crystal Xray structure determinations.
