6-Thioxanthine caused 50% inhibition of the growth of Toxoplasma gondii in human fibroblasts at a concentration of 5 micrograms/ml. A mutant induced by treatment with ethylnitrosourea (ThxR-1) was 20-fold more resistant than the wildtype. Wild-type parasites grown in Lesch-Nyhan fibroblasts efficiently incorporated hypoxanthine, guanine, and xanthine, but ThxR-1 incorporated each of these precursors less than 2% as well as the wildtype did. Soluble extracts of wild-type parasites had potent… CONTINUE READING
