afatinib

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.

(R)-Afatinib ((R)-BIBW 2992), an isomer of Afatinib, is a potent, orally administered, irreversible inhibitor targeting the ErbB family (EGFR and HER2) with IC50 values of 0.5 nM for EGFR wt, 0.4 nM for EGFR L858R, 10 nM for EGFR L858R T790M, and 14 nM for HER2, holding potential for research into esophageal squamous cell carcinoma (ESCC), non-small cell lung cancer (NSCLC), and gastric cancer [1].

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.

(S)-Afatinib (BIBW2992) is an irreversible EGFR family inhibitor with IC50s of 0.5 0.4 10 14 1 nM for EGFRwt, EGFR (L858R), EGFR (L858R T790M), HER2, and HER4, respectively.

Afatinib N-Oxide, an impurity resulting from the oxidative degradation of Afatinib, is an irreversible inhibitor of the EGFR (Epidermal Growth Factor Receptor) family.

Afatinib D6 (BIBW 2992 D6) is a deuterium-labeled Afatinib. Afatinib is an irreversible EGFR family inhibitor.

Afatinib impurity 11 is a byproduct of Afatinib, an irreversible EGFR family inhibitor with IC50 values of 0.5 nM, 0.4 nM, 10 nM, and 14 nM for EGFRwt, EGFRL858R, EGFRL858R T790M, and HER2, respectively[1].

Afatinib (BIBW 2992) oxalate is an irreversible, orally active bispecific inhibitor of the ErbB family (EGFR and HER2) with IC50 values of 0.5 nM for EGFRwt, 0.4 nM for EGFRL858R, 10 nM for EGFRL858R T790M, and 14 nM for HER2. Afatinib oxalate can be used to study esophageal squamous cell carcinoma (ESCC), non-small cell lung cancer (NSCLC), and gastric cancer.

DBPR112 is a potent EGFR inhibitor (IC50=487 nM) as a Clinical Candidate for the Treatment of Non-Small Cell Lung Cancer. DBPR112), DBPR112 not only displayed a potent inhibitory activity against EGFRL858R T790M double mutations but also exhibited tenfold potency better than the third-generation inhibitor, osimertinib,against EGFR and HER2 exon 20 insertion mutations. Overall, pharmacokinetic improvement through lead-to-candidate optimization yielded fourfold oral AUC better that afatinib along with F = 41.5%, an encouraging safety profile, and significant antitumor efficacy in in vivo xenograft models.

Neptinib (NEP010), a derivative of Afatinib, exhibits enhanced antitumor properties and improved pharmacokinetics when administered orally. It demonstrates a notable suppression of tumor expansion in mouse models of non-small cell lung cancer harboring various EGFR mutations. Furthermore, Neptinib effectively inhibits the EGFR kinase family, exhibiting IC 50 values of 0.24 nM for EGFR wt, 7.25 nM for EGFR L858R T790M, 0.46 nM for EGFR L858R, and 1.79 nM for EGFR T790M.

Becotatug (JMT-101) is an IgG1 antibody targeting EGFR, which can be conjugated to Afatinib and Osimertinib, serving as a synthetic antibody-drug conjugate (ADC) [1].
