Synthesis and characterization of dibutyltin compounds with α-amino acids
This study describes the preparation and description of four new complexes: Bu2Sn(AA)Cl (AA = glycine, DL = valine and L = leucine) and Bu2SnPhen2 (Phen = DL-phenylalanine). They were characterized by elemental analyses for carbon, hydrogen, nitrogen, chlorine and tin by infrared, 119mSn-Mössbauer and 119mSnRMN spectroscopies and by the applications of TG and DSC techniques in a dynamic helium ...
متن کاملEquilibrium Studies of Dibutyltin(IV)–Zwitterionic Buffer Complexation
Equilibrium studies in aqueous solution are reported for dibutyltin(IV) (DBT) complexes of the zwitterionic buffers "Good's buffers" Mes and Mops. Stoichiometric and formation constants of the complexes formed were determined at different temperatures and ionic strength 0.1 mol·L-1 NaNO3. The results show that the best fit of the titration curves were obtained when the complexes ML, MLH-1, MLH-...

متن کاملDibutyltin Disrupts Glucocorticoid Receptor Function and Impairs Glucocorticoid-Induced Suppression of Cytokine Production
BACKGROUND Organotins are highly toxic and widely distributed environmental chemicals. Dibutyltin (DBT) is used as stabilizer in the production of polyvinyl chloride plastics, and it is also the major metabolite formed from tributyltin (TBT) in vivo. DBT is immunotoxic, however, the responsible targets remain to be defined. Due to the importance of glucocorticoids in immune-modulation, we inves...
متن کاملEffect of taurine on acinar cell apoptosis and pancreatic fibrosis in dibutyltin dichloride-induced chronic pancreatitis.
The relationship between pancreatic fibrosis and apoptosis of pancreatic acinar cells has not been fully elucidated. We reported that taurine had an anti-fibrotic effect in a dibutyltin dichloride (DBTC)-chronic pancreatitis model. However, the effect of taurine on apoptosis of pancreatic acinar cells is still unclear. Therefore, we examined apoptosis in DBTC-chronic pancreatitis and in the AR4...
