4 Pharmacology and Biochemistry

4.1 Absorption, Distribution and Excretion

To evaluate the rate at which the four main aflatoxins (aflatoxins B1, B2, G1 and G2) are able to cross the luminal membrane of the rat small intestine, a study about intestinal absorption kinetics of these mycotoxins has been made. In situ results obtained showed that the absorption of aflatoxins in rat small intestine is a very fast process that follows first-order kinetics, with an absorption rate constant (ka) of 5.84 +/- 0.05 (aflatoxin B1), 4.06 +/- 0.09 (aflatoxin B2), 2.09 +/- 0.03 (aflatoxin G1) and 1.58 +/- 0.04 (aflatoxin G2) h-1, respectively.

4.2 Metabolism/Metabolites

Aflatoxin G2 ... /is/ the 9,10-dihydro derivative of aflatoxin G1.

O'Neil, M.J. (ed.). The Merck Index - An Encyclopedia of Chemicals, Drugs, and Biologicals. 13th Edition, Whitehouse Station, NJ: Merck and Co., Inc., 2001., p. 35

4.3 Mechanism of Action

With the 4 principal Aflatoxins tested, the order of inhibitory effect on RNA polymerase II was: B1 greater than G1 greater than B1, G2.

Yu FL et al; Carcinogenesis (London) 3 (9): 1005 (1982)

Phagocytosis, intracellular killing of Candida albicans, and superoxide production by rat peritoneal macrophages exposed to aflatoxins B1, B2, G1, G2, B2a, and M1 at several times and concentration were analyzed to evaluate the intensity of a depressive effect for each mycotoxin. All aflatoxins used at very low concn had a depressive effect on the functions of macrophages. The biggest impairment of phagocytosis, intracellular killing, and spontaneous superoxide production was observed in macrophages exposed to aflatoxins B1 and M1.
