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.

dBET6 is a selective and cell-permeable degrader of BET based on PROTAC (IC50: 14 nM). It has antitumor activity.

C004019 is a small molecule PROTAC capable of targeting tau for selective protein degradation from the cell, while recruiting tau and E3 ligase (Vhl) for selective enhancement of tau ubiquitination and proteollyzation. C004019 is a candidate for AD and related tau protein diseases.

CCT367766 is a potent, PROTAC-based, third-generation, iso-functional pirin-targeted protein degradation probe (PDP) that depletes pirin expression at low concentrations.CCT367766 has an IC50 value of 490 nM for the CRBN-DDB1 complex.CCT367766 has a good affinity for recombinant pirin and CRBN. CCT367766 has a good affinity for recombinant pirin and CRBN, with Kd values of 55 nM and 120 nM, respectively. cct367766 is a potent orally active protein that reduces the expression of pirin at low concentrations.
