Mobocertinib (tak788) is a potent inhibitor of epidermal growth factor receptor (EGFR) and an antineoplastic agent

Olmutinib (HM61713, BI 1482694) is an orally available small molecule, a mutant-selective inhibitor of epidermal growth factor receptor (EGFR) with potential antineoplastic activity. Olmutinib binds to and inhibits mutant forms of EGFR, thereby leading to cell death of EGFR-expressing tumor cells. As this agent is selective towards mutant forms of EGFR, its toxicity profile may be reduced as compared to non-selective EGFR inhibitors which also inhibit the EGFR wild-type form.

MS 39 is a potent Proteolysis Targeting Chimera (PROTAC) designed to degrade the Epidermal Growth Factor Receptor (EGFR). The molecule is composed of three structural motifs: an EGFR target ligand (red part), a VHL E3 ligase ligand (S,R,S)-AHPC (blue part), and an undecanedioic acid linker (black part). By facilitating the formation of a ternary complex between EGFR and the VHL E3 ubiquitin ligase, MS 39 triggers the polyubiquitination and subsequent proteasomal degradation of the receptor. MS 39 effectively reduces EGFR protein levels and inhibits downstream oncogenic signaling in HCC-827 and H3255 cell lines, leading to significant suppression of H3255 cancer cell proliferation.

EGFR-IN-1, an orally active and irreversible selective inhibitor targeting L858R/T790M mutant EGFR, exhibits strong antiproliferative and antitumor activity, particularly against H1975 cells and first line mutant HCC827 cells.

DHW-221 is an orally active dual PI3K/mTOR inhibitor demonstrating potent inhibition at nanomolar levels across all four Class I PI3K isoforms and mTOR (PI3Kα, IC50= 0.50 nM; PI3Kβ, IC50= 1.9 nM; PI3Kγ, IC50= 1.8 nM; PI3Kδ, IC50= 0.74 nM; mTOR, IC50= 3.9 nM). By blocking the PI3K/Akt/mTOR pathway, DHW-221 induces mitochondrial apoptosis and paraptosis (through endoplasmic reticulum stress and MAPK signaling) and causes cell cycle arrest, thereby inhibiting cell migration, invasion, and angiogenesis to exert its antitumor effects. It suppresses tumor growth in A549/Taxol and HCC827 mouse models and is applicable in research related to non-small cell lung cancer (NSCLC), colon cancer, and breast cancer[1][2][3].
