PROTAC RET Degrader 1
PROTAC RET Degrader 1 is an orally active, blood-brain barrier-penetrant RET PROTAC degrader with a DC50 of 1.7 nM. PROTAC RET Degrader 1 binds to CRBN and forms a ternary complex with RET, mediating proteasomal degradation of RET, while also selectively mediating the degradation of SALL4. PROTAC RET Degrader 1 inhibits the RET signaling pathway, hERG channel activity, and Cyp3A4 enzyme activity; it suppresses cancer cell growth and induces tumor regression. PROTAC RET Degrader 1 can be used in research related to RET-driven cancers.
(Pink: RET ligand (HY-179308); Blue: Cereblon ligand (HY-179307); Black: linker).

In Vitro
PROTAC RET Degrader 1 (compound 20) potently degrades the wild-type RET kinase domain in HEK293T cells, with a DC50 of 1.7 nM and a maximum remaining protein level of 8%; it degrades the drug-resistant RETG810R kinase domain, with a DC50 of 21 nM and a maximum remaining protein rate of 22%; it also degrades the drug-resistant RETG810S and RETG810C kinase domains, with DC50 values of 3 nM and 12 nM, and maximum remaining protein levels of 25% and 31%, respectively[1].
PROTAC RET Degrader 1 binds to CRBN in HEK293T cells, with an IC50 of 10 nM as determined by NanoBRET assay[1].
PROTAC RET Degrader 1 selectively degrades the novel CRBN substrate SALL4 (DC50 = 6.1 μM) in HiBiT-tagged cell lines, without degrading GSPT1 or IKZF1[1].
PROTAC RET Degrader 1 potently inhibits the proliferation of Ba/F3 cells expressing KIF5B-RET fusion proteins carrying drug-resistant mutations (RETG810R, RETV804L, RETY806N, RETL730I)[1].

In Vivo
PROTAC RET Degrader 1 (30 mg/kg; p.o.; single administration) can cross the blood-brain barrier, accumulate in intracranial colorectal cancer PDX tumors driven by the CCDC6-RET fusion, and induce rapid and potent RET degradation as well as pathway inhibition[1].
