摘要
We studied the effectiveness of cyclic hydroxamic acid CHA-5 against drug-resistant and multidrug-resistant murine P388 leukemia strains. More than 60% mice receiving transplantation of rubomycin-resistant leukemia P388 strain survived after CHA-5 monotherapy; combined therapy with CHA-5 and cisplatin was also highly effective. Vincristine-resistant tumor was highly sensitive to combined treatment with CHA-5 and cyclophosphamide. It should be emphasized that standard antitumor agents were used in very low doses in combination therapy and CHA-5 significantly potentiated their effect.
