| In the Search for New Anticancer Drugs, XXI. Spin Labeled Nitrosoureas  | | | Abstract
| The spin labeled nitrosoureas 7 a—e and 12 were synthesized and evaluated in vivo for their anticancer activities against the murine lymphocytic leukem ia P388. C om pounds 7 a —c, 7 e and 12 possessed activities ranging from 31 to 542 percent increase in life span (% IL S), w hereas com pound 7 d was marginal (% IL S = 21). All CD2Fj male mice treated with the most active com pounds (7a and 12) at 35 mg/kg for 9 days were alive after 30 days, w hereas all mice treated with the clinical drug CCNU (lc) succumbed. Compounds 7 a —e and 12 were further evalu ated for their antineoplastic activity against lymphoid leukem ia L1210. C om pounds 7a and 12 exhibited, on day 60, a % ILS of 713 and 620, respectively. The lipophilicities of com pounds 7 a —e and 12 were determ ined using the E PR and UV methods. Compounds 7a and 12 which differ from CCNU and M eCCNU by the replacement of the cyclohexyl and methylcyclohexyl groups with six and five m em bered nitroxyl radical moieties were more hydrophilic than the clinical drugs. | | |
