title: Antineoplastic properties of arylsulfonylhdrazones of 3-formylpyridazine 2-oxide and 4-formylpyrimidine 3-oxide.
abstract: The antineoplastic activity of several arylsulfonylhydrazones of 4-formylpyrimidine 3-oxide and of 3-formylpyridazine 2-oxide has been investigated. Derivatives of the latter heteroaromatic N-oxide showed excellent antineoplastic potency against the murine neoplasm Sarcoma 180 but were inactive against leukemia L1210. In contrast, derivatives of 4-formylpyrimidine 3-oxide were inactive against both of these transplanted tumors.
