VPC-16606
VPC-16606 is a selective inhibitor targeting the activation function 2 (AF2) domain of estrogen receptor α (ERα). VPC-16606 blocks the interaction between ERα and coactivators, inhibits the activity of both wild-type and clinically drug-resistant mutant ERα, and exerts inhibitory effects on hormone-resistant breast cancer cells. VPC-16606 can be used in breast cancer research.

Biological Activity
VPC-16606 (24 h) potently inhibits the transcriptional activity of ERα in T47D-KBluc human breast cancer cells, with an IC50 of 0.31 μM[1].
VPC-16606 (1.6-50 μM; 24 h) blocks the interaction between ERα and the coactivator SRC-3 in MDA-MB-231 cells[1].
VPC-16606 (0-50 μM; 96 h) exerts ERα-specific antiproliferative effects on ERα-positive, Tamoxifen (HY-13757A)-resistant human breast cancer cells[1].
VPC-16606 (0.38-6 μM; 24 h) downregulates ERα-dependent gene expression in MCF7 cells and Tamoxifen (HY-13757A)-resistant TamR3 human breast cancer cells[1].
