Abstract
The 50% effective doses of fusarenon X, nivalenol, deoxynivalenol, and 15-acetyldeoxynivalenol required to reduce [3H]thymidine uptake in mitogen-stimulated human lymphocytes by 50% were 18, 72, 140, and 240 ng/ml, respectively. These results indicated that lymphotoxicity of 8-ketotrichothecenes decreased according to the C-4 substituent order acetyl greater than hydroxyl greater than hydrogen, whereas acetylation of position C-15 of deoxynivalenol caused a slight decrease in in vitro toxicity. The 50% effective doses for zearalenone, alpha-zearalenol, beta-zearalenol, alpha-zearalanol, and beta-zearalanol were 3,500, 6,300, 36,000, 3,750, and 33,000 ng/ml, respectively, suggesting that a keto group or alpha-hydroxyl at the position C-6' contributed to the lymphotoxicity of the parent molecule. The inhibitory effects of zearalenone analogs observed in the blastogenesis assay did not correlate with the estrogenic potencies of these compounds. All 8-ketotrichothecenes and zearalenone analogs tested were capable of inhibiting B- and T-cell subsets stimulated by a mitogen panel of leukoagglutinin, concanavalin A, and pokeweed mitogen.
