Abstract: 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-carboxam ide.
