Chemical Structure
LG-120753
- CAS No.: 179894-84-9
- Formula:C19H18N2
- Molecular Weight:274.36
InChIKey: PDEIPQPDODOWPI-UHFFFAOYSA-N
SMILES: N#CC1=CC=CC(C2=CC=C3NC(C)(C)C=C(C)C3=C2)=C1
Biological Activity: LG-120753 is an orally active nonsteroidal progesterone receptor (PR) antagonist, with an IC50 of 38 nM against hPR-B, a Ki of 19 nM against hPR-A, an IC50 of 227 nM against hAR, and IC50 values greater than 1000 nM against hGR, hER and hMR. LG-120753 blocks the action of progesterone, binds to and antagonizes hPR-A, and shows limited cross-reactivity with other steroid receptors. LG-120753 blocks blastocyst implantation, prevents the establishment of pregnancy, exhibits dose-dependent antiprogestogenic activity in vivo, and induces reversible antifertility effects[1].
