In vitro: MCB-613 selectively and reversibly binds to the RID of SRC-3, and selectively kills cancer cells including MCF-7 (breast), PC-3 (prostate), H1299 (lung), and HepG2 (liver) cells, without toxicity to mouse primary hepatocytes and mouse embryonic fibroblasts (MEFs). MCB-613 also increases SRCs’ interactions with other coactivators and markedly induces ER stress coupled to the generation of reactive oxygen species (ROS).
In vivo: In an MCF-7 breast cancer mouse xenograft model, MCB-613 (20 mg/kg, i.p.) significantly and dramatically inhibits the growth of the tumor while causing no obvious animal toxicity and body weight less.

Preparation method | Cells are seeded in 96-well plates and allowed to reach 60% to 70% confluence. After indicated compound treatments, relative numbers of viable cells are measured by MTS assay using the Cell Titer 96 Aqueous One Solution Cell Proliferation Assay. |

Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
