AIM: From betulinic acid (1a), we synthesized 30-oxobetulinic acid (2a) that is highly cytotoxic against many cancer cell lines; however, its generic toxicity is the main obstacle in further development as cytostatic. Methodology & results: From 2a, we prepared a new class of compounds - nonsymmetrical azines and tested their in vitro cytotoxicity. All new azines with a free 28-COOH group (4a-4e) were highly and selectively cytotoxic against the T-lymphoblastic leukemia cell line CCRF-CEM and exhibited dose-dependent inhibition of RNA and DNA synthesis and other cell-cycle alterations, including the M-phase block. CONCLUSION: The potential use of azines (4a-4e) in drug development focused on hematological cancers is significantly higher than that of previously studied acids 1a and 2a.
