PROTAC RET Degrader 2
PROTAC RET Degrader 2 is a RET degrader with a target IC50 of 0.36 nM. PROTAC RET Degrader 2 is mainly composed of RET-IN-34 (HY-183729) and Thalidomide (HY-14658). PROTAC RET Degrader 2 mediates RET degradation via the ubiquitin-proteasome system. PROTAC RET Degrader 2 induces apoptosis, inhibits colony-forming ability, and exhibits antiproliferative activity in cancer cells. PROTAC RET Degrader 2 suppresses tumor growth in xenograft models. PROTAC RET Degrader 2 can be used in research related to medullary thyroid carcinoma, papillary thyroid carcinoma, and RET fusion-positive lung adenocarcinoma.

PROTAC RET Degrader 2 (JW15) potently inhibits RET kinase in a cell-free biochemical assay with an IC50 of 0.36 nM[1].
PROTAC RET Degrader 2 (0.0762-500 nM; 0-240 h) potently degrades RET (DC50 = 0.26 nM) and inhibits proliferation (GI50 = 1.2 nM) in TT human medullary thyroid carcinoma cells, with near-complete RET depletion at 2-6 nM and complete degradation by 24 h at 10 nM[1].
PROTAC RET Degrader 2 degrades RET (85.6% at 100 nM, DC50 = 7.84 nM) and inhibits proliferation (GI50 = 13.7 nM) in RET Ba/F3 cells[1].
PROTAC RET Degrader 2 potently degrades RET (DC50 = 8.77 nM) and inhibits proliferation (GI50 = 15 nM) in TPC-1 human papillary thyroid carcinoma cells[1].
PROTAC RET Degrader 2 potently degrades RET (DC50 = 39.85 nM) and inhibits proliferation (GI50 = 17 nM) in LC-2/ad human lung adenocarcinoma cells[1].
PROTAC RET Degrader 2 (10 nM; 24 h) induced RET degradation in TT human medullary thyroid carcinoma cells is attenuated by pretreatment with selpercatinib or a CRBN binder, confirming it requires dual binding to RET and CRBN[1].
PROTAC RET Degrader 2 (10 nM; 6 h) induces RET degradation in TT human medullary thyroid carcinoma cells via the ubiquitin-proteasome system, not autophagy[1].
PROTAC RET Degrader 2 engages CRBN in BRD4-eGFP-mCherry HeLa cells, as demonstrated by dose-dependent rescue of dBET6-induced BRD4 degradation[1].
PROTAC RET Degrader 2 (0.1-10 nM; 24 h) effectively inhibited RET phosphorylation and downstream signaling pathways (STAT3, ERK, S6RP) in human medullary thyroid carcinoma TT cells[1].
PROTAC RET Degrader 2 (50 nM; 12 h) induces selective degradation of RET kinase at the kinome-wide level in RET Ba/F3 cells[1].
PROTAC RET Degrader 2 (0.1-1 nM; 120 h) induces significant apoptosis in TT human medullary thyroid carcinoma cells at 1 nM after 120 h of treatment[1].
PROTAC RET Degrader 2 (0.1-10 nM) potently inhibits 2D colony formation in TT human medullary thyroid carcinoma cells[1].
PROTAC RET Degrader 2 (0.1-10 nM; 4 week) potently inhibits anchorage-independent 3D colony formation in TT human medullary thyroid carcinoma cells[1].

Cell Line:TT human medullary thyroid carcinoma cells
-
Concentration:10 nM
-
Incubation Time:2 h (pretreatment); 24 h (JW15 incubation)
-
Result:Pretreatment with either selpercatinib (HY-114370) or 5-aminothalidomide (HY-W023573) attenuated JW15-induced RET degradation, confirming JW15 requires binding to both RET and CRBN to drive degradation.
