Syntheses and Evaluation of Some Mannich Bases Derived from Acetophenones Against P38 8 Lymphocytic Leukemia and Toxicological Assessment of 3-Dimethylamino-2-dimethylaminomethyl- 1 -(4-methoxypheny1)- 1 -Propanone Dihydrochloride in Rats
analogues of 3-dimethylamino-2-dimethylaminomethyl-1-(4-methoxyphenyl)-1-propanone dihydrochloride (IIa) and related compounds which showed activity against P388 lymphocyticleukemia were prepared, and of the 16 analogues, three met the criterion for activity in this screen. The toxicity of IIa was examined in rats and either a single dose of 25 mg/kg or nine daily doses of 12.5 mg/kg administered
