Metabolite Identification
Common NameChlordecone alcohol
DescriptionChlordecone alcohol is the major metabolite of Chlordecone [ an organochlorine pesticide, CAS# 143-50-0] in humans via bioreduction in the liver by Chlordecone reductase [EC: 1.1.1.225 ,CAS # 102484-73-1]. (PMID 2420999 ). Chlordecone treatment actively suppresses induction of 2B1 and 2B2 mRNAs in adult human hepatocytes; anti-estrogens such as Tamoxifen fail to reverse 2B1/2 mRNA induction following Chlordecone treatment of hepatocytes. (PMID 7513451 ). Both Chlordecone and Chlordecone alcohol alter the permeability of isolated ovine erythrocytes. (PMID 2455063 ).

Enzymes

General function:
Involved in oxidoreductase activity
Specific function:
Catalyzes the transformation of the potent androgen dihydrotestosterone (DHT) into the less active form, 5-alpha-androstan-3-alpha,17-beta-diol (3-alpha-diol). Also has some 20-alpha-hydroxysteroid dehydrogenase activity. The biotransformation of the pesticide chlordecone (kepone) to its corresponding alcohol leads to increased biliary excretion of the pesticide and concomitant reduction of its neurotoxicity since bile is the major excretory route.
