in present studies the synthesis, characterization and biological properties ofoxovanadium(iv) coordination compounds of 4[n-(4′-ethylbenzalidene)amino] antipyrinethiosemicarbazone (ebaapts) and 4[n-(2′,4′-dimethylbenzalidene)amino] antipyrinethiosemicarbazone (dmbaapts) with the general composition vox2l (x = c1-, br-, i-, no3-or ncs-) and vo(cio4)2(l)h2o (l = ebaapts or dmbaapts) are describe...

A robust tris-oxovanadium tris-anion showing interesting electrochemical and magnetic properties due to the combination of V( iv ) with a non-innocent pyrogallate ligand.

   Various radiometal complexes have been developed for tumor imaging, especially Ga-68 tracer. In the present study, the development of a radiogallium bis-thiosemicarbazone complex has been reported. [67Ga] acetylacetonate bis(thiosemicarbazone) complex ([67Ga] AATS) was prepared starting [67Ga]Gallium acetate and freshly prepared acetylacetonate bis (thiosemicarbazone) (AATS) in 30 min at 90°...

Dois novos complexos [VO2(L)] e [VO2(HLox)] foram sintetizados e caracterizados por espectroscopias no IV, UV-Vis e RMN, voltametria cíclica, análise elementar e difração de raios X. A síntese do ligante inédito H2Lox também é descrita. Os complexos 1 e 2 foram obtidos pela reação de [VO(acac)2] com os respectivos ligantes HL e H2Lox. Alternativamente, 2 foi preparado a partir da reação de HL c...

The general affinity of the sarcoplasmic reticulum (SR) Ca (2+)-ATPase was examined for three different classes of vanadium coordination complexes including a vanadium(V) compound, pyridine-2,6-dicarboxylatodioxovanadium(V) (PDC-V(V)), and two vanadium(IV) compounds, bis(maltolato)oxovanadium(IV) (BMOV), and an analogue of amavadine, bis( N-hydroxylamidoiminodiacetato)vanadium(IV) (HAIDA-V(IV))...

The water soluble oxovanadium(IV) tetraarylporphyrin has demonstrated excellent solution stability against glutathione reduction and high potency (5 microM, 97% inhibition) in inhibiting HIV-1 replication in Hut/CCR5 cells.
