3-methylcholanthrene

3-meth·yl·chol·an·threne

(meth'il-kōl-an'thrēn),
A highly carcinogenic hydrocarbon that can be formed chemically from deoxycholic or cholic acids, or from cholesterol; it induces the synthesis of cytochrome P-450 mRNA; the choice between 3- or 20- for the methyl group depends upon whether hydrocarbon (inner) or steroid (outer) numbering is chosen; in the latter case, the formal relationship to the cholic acids and cholesterol is clear.
