Abstract

The effect of NO-synthase (NOS) activator and inhibitors on leukemic cell lines HL-60, K-562, and MOLT-4 and bone marrow cells of untreated patients diagnosed with B-cell acute lymphoblastic leukemia compared with lymphocytes from healthy donors is examined. The obtained data on the relationships between the radioprotective, NOS inhibitory, and cytotoxic properties of a number of thiazine, thiazoline, and thiourea derivatives indicates their potential for use as agents for complex radio- and chemotherapy.
