Pharmacological properties of racemic chlorobromofosfamide.

Racemic chlorobromofosfamide (CBM-4A) is a bromine substituted analog of ifosfamide. The studies reported here were aimed at establishing the general pharmacological properties and toxicologic profile of this compound. Acute and cumulative toxicity, behavioral screening tests and effects of subchronic and chronic treatment (influence on body weight, mortality, blood morphology, proteins level, urea and creatinine concentration, enzymes activity) were taken into account.

Comparison of pharmacological properties of rubidomycine and its newly synthesized derivatives DR-22 and DR-27 in animals.

The effect of two newly synthesized 5-amino modified analogues of rubidomycine was submitted to preliminary pharmacological and histological investigations in healthy Albino Swiss mice. The results showed a similarity of the tested properties of the new compounds and commercial rubidomycine, suggesting the same spectrum undesired side-effects after acute administration. Of the two novel compounds DR-22 was found to be less toxic, while much potent in its action on the haematopoietic system in comparison to rubidomycine, in prolonged treatment.

Comparison of selected pharmacological properties of trofosfamide and its enantiomeric derivatives.

Comparison of pharmacological properties of commercial, racemic trofosfamide (Ixoten) and its dextrorotatory and levorotatory derivatives was performed in experiments on mice. Acute and cumulative toxicity, behavioral screening tests and effects of subchronic treatment (growth of body mass, mortality, blood morphology, proteins level, enzymes activity, microscopic evaluation of liver slices) were taken into account. Summarized data revealed more pronounced toxicity of enantiomers, particularly D-form, as compared with racemate.

Pharmacological evaluation of ifosfamide and its enantiomers in laboratory animals.

Some pharmacological properties of commercial racemic ifosfamide (Holoxan) and its D- and L-enantiomers were compared in experiments on mice and rats. Although values of acute toxicity and some results of subchronic treatment revealed better parameters of L-form in comparison to racemic mixture, distinct hepatotoxic effects and thrombocytopenia noted in the course of prolonged treatment seem to be the important factors limiting therapeutic usefulness of levorotatory form.

comparison of pharmacological properties of cyclophosphamide and its enantiomers.

Comparison of pharmacological properties of commercial racemic Cyclophosphamide and its D- and L-enantiomers was performed in experiments on mice and rats. Acute toxicity, behavioral screening tests and the effects of subchronic treatment (influence on body mass, the increase of the mass of internal organs, mortality, morphology of peripheral blood, biochemical investigations of blood plasma, microscopic evaluation of liver and bladder) were taken into account. Summarized results revealed the most pronounced toxicity of D-cyclophosphamide.
