Miller MC, Sood A, Spielvogel BF, Bastow K, Hall IH.
PMID: 18475792
Met Based Drugs. 1997;4(4):229-41. doi: 10.1155/MBD.1997.229.

The heterocyclic carboxyborane amines were found to be potent cytotoxic agents in the murine L1210 lymphoid leukemia and human HeLa suspended carcinoma cells. These agents were observed to inhibit HeLa DNA topoisomerase II activity ~ 200 muM and L1210...
