The investigation has established a potential of low-dosage chemotherapy with cytostatics when used in combination with nitric oxide (NO) donor. Such regimen resulted in more animals being cured of leukemias P388 and L1210 and longer survival. Similar effect was reported with transplantable intracerebral leukemia P388 in which case mean survival after cyclophosphamide plus NO-donor was three times as high as that after cyclophosphamide alone. Combination therapy also promoted animetastatic effect: melanoma B16 inhibition by cyclophosphamide alone was 50% vs. 80% after cyclophosphamide plus NO-donor. NO-donor inhibited development of drug resistance to cyclophosphamide.
