  Comparativein vivoLead Mobilization ofmeso- andrac-2,3-Dimercaptosuccinic Acids in Albino Wistar Rats

  摘要：

  Abstract: Comparison of the racemic and meso forms of 2,3‐dimercaptosuccinic acid (DMSA) in lead mobilization from lead‐loaded albino Wistar rats demonstrates that the racemic form is significantly more effective in reducing femur lead levels. After four oral doses at 0.5 mmol/kg, femur lead levels were reduced to 87% of control values by meso‐DMSA and to 50% of control levels by rac‐DMSA. Similarly, when the dose was increased to 1.0 mmol/kg, femur lead levels were reduced to 69% of control levels by meso‐DMSA and to 45% of control levels by rac‐DMSA. A similar pattern was found for renal lead levels. Brain lead concentrations were significantly lower in treated groups than in control groups, but no differences were found between rac‐ and meso‐DMSA. Rac‐DMSA is more soluble than meso‐DMSA in acetonitrile, ethyl acetate, and ethyl ether. The partition coefficient of rac‐DMSA in the n‐octanol/water system was found to be about 2.8. These results indicate that rac‐DMSA deserves further attention as a possible substitute for meso‐DMSA.

  Abstract A series of ten bis(dithiolato)oxotechnetate(V) complexes has been prepared using ligand exchange reaction. Starting from Tc(V) gluconate in aqueous or aqueous/ethanolic solution, complexes with saturated, olefinic and aromatic dithioles have been obtained. Mass, infrared, n.m.r., and UV-visible data of the resulting compounds are reported.
