Abstract
The in vivo toxicity profiles in mice and the antitumour activity in tumour bearing mice were screened for four di-n-butyltin and five triorganotin carboxylates, di-n-butyltin diterebate (5), bis(phenylacetate) (6), bis(deoxycholate) (7), bis(lithocholate) (8), tri-n-butyltin terebate (9), cinnamate (10), and triphenyltin terebate (11).
At their maximum tolerated dosis (MTD), no antitumour effect (T/C ~1) was observed for the compounds 5, 7, 9, 10 and 11. The compounds 6 (T/C = 0.51) and 8 (T/C = 0.42) showed clear antitumour activity after single dose administration and might therefore be of interest for further antitumour activity studies.
