| Bioactivity | 3,3'-Diindolylmethane is a strong, pure androgen receptor (AR) antagonist. |
| Invitro | 3,3'-Diindolylmethane (DIM) is a strong antagonist of androgen receptor (AR) function but exhibits less than obvious structural similarity to the endogenous AR ligand, dihydrotestosterone (DHT). 3,3'-Diindolylmethane is a major digestive product of indole-3-carbinol, a potential anticancer component of cruciferous vegetables. 3,3'-Diindolylmethane exhibits potent antiproliferative and antiandrogenic properties in androgen-dependent human prostate cancer cells. 3,3'-Diindolylmethane suppresses cell proliferation of LNCaP cells and inhibits DHT stimulation of DNA synthesis. Moreover, 3,3'-Diindolylmethane inhibits endogenous PSA transcription and reduced intracellular and secreted PSA protein levels induced by DHT in LNCaP cells. Also, 3,3'-Diindolylmethane inhibits, in a concentration-dependent manner, the DHT-induced expression of a prostate-specific antigen promoter-regulated reporter gene construct in transiently transfected LNCaP cells. Co-treatment with 50 μM 3,3'-Diindolylmethane partially inhibits the translocation of AR induced by DHT treatment and showed distribution of the AR to be both cytoplasmic and nuclear. Furthermore, 3,3'-Diindolylmethane treatment prevents the formation of AR foci in the nucleus. 3,3'-Diindolylmethane alone produces a predominantly cytoplasmic distribution of fluorescence[1]. |
