Indole-3-carbinol (I3C) is a naturally occurring plant alkaloid, found in significant concentrations in cruciferous vegetables such as broccoli and Brussels sprouts. I3C is an unstable compound that undergoes rapid oligomerization in an acidic environment to form higher order condensation products (I3C-ACPs), such as 3-3'-diindolylmethane (DIM). Both I3C and DIM are...
Indole-3-carbinol (I3C) and 3,3'-diindolylmethane (DIM), a primary I3C
derivative in vivo, are known chemopreventive agents available as dietary supplements.
I3C was found to suppress or enhance tumors in several animal models.
Chemoprotection is attributed to the ability of indoles to alter carcinogen metabolism
effectively blocking initiation. However, mechanisms for enhancement...
