Vepdegestrant (ARV-471) is an estrogen receptor (ER) α PROTAC molecule that degrades ER in ER-positive breast cancer cell lines with a DC50 of approximately 1 nM. It can reduce the expression of classically regulated ER target genes and inhibit the growth of ER-dependent cell lines (including those expressing ESR1 variants, such as Y537S and D538G) by degrading ER.

CFT1946 is a Bifunctional Degradation Activating Compound (BiDAC) degrader that contains a ligand targeting the BRAF kinase domain linked to a cereblon ligand. CFT1946 is able to degrade BRAF V600E (class I), G469A (class II), G466V (class III) mutations and p61-BRAFV600E splice variants while maintaining excellent selectivity for the proteome including WT BRAF and CRAF.
