Biochemical changes in cultured murine fibroblasts after treatment with hydrazinophthalazines.
Fibroblast cultures exposed to the drugs inducing a collagen-like syndrome (hydralazine and binazine) displayed growth inhibition and decrease in cellular protein content in a dose-dependent manner compared with control cultures. This was accompanied by the inhibitory effect of the drugs on DNA synthesis. The changes in the basic biochemical parameters of fibroblasts testify to the toxicity of hydrazinophthalazines in the connective tissue.
