  Quantitative structure-activity relationships of antitumor guanidinothiazolecarboxamides with survival enhancement for therapy in the 3LL Lewis lung carcinoma model

  摘要：

  Guanidinothiazolecarboxamides (GTCs) are a novel class of antitumor agents found to be systemically active against experimental pulmonary metastases of 3LL Lewis lung carcinoma. A series of substituted benzothiazole GTCs were found to produce enhancement of survival in this model by using 8 days of intraperitoneal dosing initiated 2 days after intravenous tumor challenge. Quantitative structure-activity relationships have been discovered in the GTC series with survival enhancement correlated to substituent parameters. Optimal correlations were found between the probit transform of the drug-induced increased lifespan (ILS) and field and pi parameters. Among the most effective analogues in this series was N-(5-fluorobenzothiazol-2-yl)-2-guanidinothiazole-4-carboxamide (19).

  N-(5-Fluorobenzothiazol-2-yl)-2-guanidinothiazole-4-carboxamide (1) is a member of a series of amides found to substantially increase lifespan in mice bearing established micrometastatic 3LL Lewis lung carcinoma. Amide 1 is effective after either oral or intraperitoneal dosing in acute, subacute, or chronic regimens. 1 is well tolerated in this model with an excellent therapeutic index relative to the cytotoxic anticancer drug adriamycin.
