Afatinib (BIBW 2992) is an irreversible inhibitor of the EGFR family (EGFR-wt, EGFR-L858R, EGFR-L858R T790M, and HER2) with IC50s of 0.5 nM, 0.4 nM, 10 nM, and 14 nM, respectively.

Panitumumab is a fully human IgG2 monoclonal antibody targeting the epidermal growth factor receptor EGFR).

Afatinib Dimaleate (BIBW 2992MA2) is an orally bioavailable anilino-quinazoline derivative and inhibitor of the receptor tyrosine kinase (RTK) epidermal growth factor receptor (ErbB; EGFR) family, with antineoplastic activity.

Rezivertinib (BPI-7711) is an orally available, selective and potent inhibitor of tyrosine kinase (EGFR) with antitumor activity for central nervous system disorders.

EGFR-IN-55 is a potent inhibitor of EGFR, acting on EGFRWT (IC50: 70 nM) and EGFRL858R T790M (IC50: 3.9 nM). EGFR-IN-55 was able to block the cell cycle of NCI-H1975 cells in G0 G1 phase, exhibiting anticancer effects.

PROTAC EGFR degrader 7 (compound 13b) is a potent and selective CRBN-recruiting agent targeting EGFR L858R T790M mutations with a DC50 of 13.2 nM. It effectively inhibits proliferation in NCI-H1975 cells with an IC50 of 46.82 nM and significantly induces apoptosis and G2 M phase arrest in these cells. Demonstrating antitumor efficacy, PROTAC EGFR degrader 7 holds promise for non-small cell lung cancer (NSCLC) research [1].

PROTAC EGFR degrader 7 (compound 13b) is a potent, selective, CRBN-recruiting EGFRL858R T790M degrader with a DC50 of 13.2 nM. It effectively inhibits NCI-H1975 cell proliferation with an IC50 of 46.82 nM, induces apoptosis, and causes G2 M phase arrest. This compound shows antitumor activity and is applicable in non-small cell lung cancer (NSCLC) research.

EGFR-IN-97 (compound 6q), an EGFR inhibitor, demonstrates effectiveness in inhibiting Ba F3-EGFR L858R T790M C797S and Ba F3-EGFR Del19 T790M C797S cells, exhibiting IC 50 values of 0.42 μM and 0.41 μM, respectively. Additionally, at a concentration of 0.8 μM, EGFR-IN-97 is capable of inducing apoptosis in NCI-H1975-EGFR L858R T790M C797S cells [1].

PI3Kα-IN-15 is a powerful inhibitor of PI3Kα, exhibiting an IC₅₀ of 0.15 μM. It shows promising anti-proliferative effects, inhibiting the growth of SKOV-3, T47D, NCI-H1975, NCI-H460, and MCF-7 cell lines with respective IC₅₀ values of 26.6 μM, 7.9 μM, 32.1 μM, 17.7 μM, and 9.4 μM. This compound is useful for cancer research [1].

DFX117 is an orally effective selective inhibitor of PI3Kα and c-Met tyrosine kinase (c-Met). This compound inhibits the PI3K Akt mTOR pathway and suppresses the proliferation of NCI-H1975, NCI-H1993, and HCC827 cells, with IC50 values ranging from 0.02 to 0.08 µM. Additionally, DFX117 induces cell cycle arrest in the G0 G1 phase and triggers apoptosis (apoptosis) in A549 and NCI-H1975 cells. It also exhibits antitumor activity in mice.

TAS-121 is an orally active, selective, covalent third-generation mutant EGFR tyrosine kinase inhibitor (EGFR-TKI). It effectively inhibits the L858R mutation (IC50=1.7 nM), Ex19del mutation (IC50=2.7 nM), L858R T790M mutation (IC50=0.56 nM), and Ex19del T790M mutation (IC50=1.1 nM), as well as wild-type EGFR (IC50=8.2 nM). TAS-121 also inhibits HER2 and HER4 with an IC50 of 110 nM and 2.6 nM, respectively. This compound prevents cellular proliferation by inhibiting the phosphorylation of EGFR and its downstream signaling targets, thereby inducing apoptosis. Additionally, TAS-121 demonstrates antitumor activity in xenograft models such as SW48 (EGFR G719S) and NCI-H1975 (EGFR L858R T790M).
