Surface seawaters from the Dona Paula Bay, were collected at weekly intervals during March 2007 to March 2008, and analyzed for butyltins (BT) such as tributyltin (TBT), dibutyltin (DBT), monobutyltin (MBT) using a GC-MS system. The mean concentrations of TBT, DBT, MBT and total BT varied from <1-37, 4-19, 6-28 and 21-84 ng Sn L(-1), respectively. Highest levels of BTs were recorded during May ...

The organotin compounds dibutyltin (DBTC) and diphenyltin dichlorides (DPTC) were tested for trypanocidal activity on a Trypanosoma brucei-infected mice model. At a dose of 10 mg DBTC and 15 mg DPTC/kg/day for five consecutive days, they cleared the parasites from the peripheral blood of the infected mice. Subinoculation of some healthy mice with the homogenates of liver, spleen, kidney, cerebr...

A GC-MS with electron impact ionization was used for the development of a speciation method for the simultaneous determination of monobutyl-, dibutyl-, and tributyltin in environmental samples (waters, sediments, and biota). The method is based on the use of a mixed spike containing Sn-enriched monobutyltin (MBT), dibutyltin (DBT), and tributyltin (TBT) for isotope dilution analysis. The mixed ...

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 ...
