YW-N-7 TFA
YW-N-7 TFA is a PROTAC degrader targeting RET kinase, with an IC50 of 8.4 nM. YW-N-7 TFA inhibits RET kinase activity and induces proteasome-mediated degradation of RET fusion proteins, while enhancing the anti-tumor activity of Selpercatinib (LOXO-292) (HY-114370). YW-N-7 TFA can be used in the research of cancers associated with RET gene abnormalities, including medullary thyroid carcinoma, papillary thyroid carcinoma and non-small cell lung cancer.
(Pink: RET ligand (HY-170856); Blue: Cereblon E3 ligase ligand; Black: linker (HY-W086181)).

In Vitro
YW-N-7 (10-1000 nM) TFA potently inhibits the proliferation of human TPC1 thyroid cancer cells and enhances the antiproliferative activity of Selpercatinib (LOXO-292) (HY-114370) in these cells[1].
YW-N-7 (200 nM; 24 h) TFA exhibits high specificity for RET in human TPC1 thyroid cancer cells[1].
YW-N-7 (0.1-500 nM; treated for 3 days in BaF3 cell line, treated for 5 hours in IMR-90 cells) TFA selectively inhibits the viability of BaF3/KIF5B-RET cells, but shows no activity against IL-3-dependent BaF3 cells, VEGFR2-dependent BaF3/TEL-VEGFR2 cells, or normal IMR-90 human diploid fibroblasts[1].
YW-N-7 (50-250 nM; 15 h) TFA inhibits RET kinase activity and degrades KIF5B-RET protein in BaF3/KIF5B-RET cells[1].
YW-N-7 (0.1-500 nM; 3 days) TFA potently inhibits the proliferation of BaF3/KIF5B-RET cells[1].
YW-N-7 (TFA) (200 nM; 24 h) significantly reduces RET protein abundance in CCDC6-RET fusion-positive TPC1 thyroid cancer cells[1].

Result:Inhibited RET kinase activity and degraded CCDC6-RET protein in a dose-dependent manner.
Reduced CCDC6-RET protein with a half-life of 2 h at 50 nM, reaching a maximal 97.3% reduction at 9 h, and maintaining 93.5% reduction at 24 h.
Reduced CCDC6-RET protein with a half-life of 5 h at 250 nM, with a maximal 88% reduction at 9 h.

Blocked CCDC6-RET degradation but still inhibited kinase activity when cotreated with bortezomib.
Exhibited an IC50 of 8.4 nM for RET autokinase inhibition and an IC50 of 26.4 nM for CCDC6-RET degradation.
