ret v804m in 1

RET V804M-IN-1 (RETV804M kinase inhibitor) is a wt-RET -selective RETV804M kinase inhibitors(IC50 = 20 nM).

RET-IN-1 is a RET kinase inhibitor with IC50 values of 1 nM for RET (WT), 7 nM for RET (V804M), and 101 nM for RET (G810R).

QZ2135 (compound 20) is a PROTAC degrader that specifically targets RET and exhibits antitumor activity in vivo within a Ba/F3-KIF5B-RET-G810C xenograft mouse model. The compound demonstrates degradation activity with DC50 values of 4.7 nM (WT), 17.2 nM (V804M), and 73.8 nM (G810C) when targeting KIF5B-RET. QZ2135 is composed of the target protein ligand (red part) RETligand-3, the E3 ligase ligand (blue part) Lenalidomide-F, and the PROTAC Linker (black part) 7-Iodohept-1-yne, wherein the target protein ligand combined with the linker forms the conjugate RETLigand-Linker Conjugate-1.

APS03118 is an orally effective, potent, and highly selective RET inhibitor. It broadly inhibits RET fusions and various mutations (including G810, V804, L730, and Y806 variants), with IC50 values generally below 1 nM (0.0952 nM for the wild type; mutation IC50s range from 0.00438 to 5.72 nM), demonstrating significant inhibitory activity against RETG810 mutations. APS03118 effectively suppresses the entire RET signaling pathway, including RET, Shc, and ERK1/2, and shows more than 20-fold selectivity over most off-target kinases, excluding FLT3 and YES. In vivo, APS03118 induces complete tumor regression in KIF5B-RET and CCDC6-RET V804M PDX mouse models and significantly extends survival in intracranial CCDC6-RET metastatic mouse models. This compound is applicable for research on RET-driven cancers resistant to selective RET inhibitors (SRI).

RET-IN-12 is a RET inhibitor capable of acting on RET(WT) (IC50: 0.3 nM) and RET(V804M) (IC50: 1 nM).

RET-IN-22 (compound 17b) is a potent, selective, and orally active inhibitor of RET, exhibiting IC50 values of 20.9 nM for wild-type RET and 18.3 nM for RET-V804M. It demonstrates a highly selective inhibition profile across a broad spectrum of kinases, with notable specificity over EGFR and VEGFR2, and is implicated in exerting anticancer effects [1].
