DIM-C-pPhOH (Synonyms: DIM-C-pPhOH, 1,1-bis-(3’-indolyl)-1-(p-hydroxyphenyl)methane)

DIM-C-pPhOH is a nuclear receptor 4A1 (NR4A1) antagonist. DIM-C-pPhOH inhibits cancer cell growth and mTOR signaling, induce apoptosis and cellular stress. DIM-C-pPhOH reduces cell proliferation with IC50 values of 13.6 μM and 13.0 μM for ACHN cells and 786-O cells, respectively[1].

DIM-C-pPhOH (7.5-20 μM; 24 hours; ACHN and 786-O cells) treatment significantly decreases cell proliferation[1].DIM-C-pPhOH (20 μM; 24 hours; ACHN and 786-O cells) treatment induces Annexin V staining in ACHN and 786-O cells, confirming that DIM-C-pPhOH induce apoptosis, and also induces cleavage of caspases 7 and 8[1].DIM-C-pPhOH (15-20 μM; 24 hours; ACHN and 786-O cells) treatment inhibits NR4A1-regulated expression of survivin, bcl-2 and EGFR in ACHN and 786-O cells. And also induces sestrin 2, activates AMPKα and inhibits activation of mTOR and downstream kinases[1].DIM-C-pPhOH decreases expression of β1-integrin protein and mRNA and β1-integrin-dependent responses in MCF7, MDA-MB-231, and SKBR3 cells and also inhibits migration of the latter two cell lines[2]. Cell Proliferation Assay[1] Cell Line: ACHN and 786-O cells

DIM-C-pPhOH (30 mg/kg; oral gavage; daily; for 50 days; male athymic nude mice) treatment results in a significant inhibition of tumor growth[1]. Animal Model: Male athymic nude mice (aged 6-7 weeks) injected with ACHN cells[1]
