Abstract:
A considerable blastogenic activity of biogenic methoxyindoles--melatonin, 5-methoxytryptamine (5-MOT) and their common metabolite--5-methoxyindolyl-3-acetic acid (5-MIAA) was established by prolonged s.c. injection in C57BL/6 mice. However, the blastogenic effect of 5-MOT decreased by 26% when its further metabolism to 5-MIAA was blocked for some time and the synthesis of its carcinogenic metabolite was inhibited. These results showed that the blastogenic effect of 5-MOT is not direct; and it is mediated by its transformation to 5-MIAA in the body.
