ZW-49 is an orally active pan-EGFR inhibitor with IC₅₀ values at 0.03-1.5 nM. ZW-49 inhibits all subgroups of EGFR mutations with selectivity over wild-type EGFR and other target families. ZW-49 blocks the ATP-binding pocket, occupies a conserved hydrophobic subpocket, avoids steric conflicts with PACC mutation P loops. ZW-49 inhibits cancer cells proliferation, induces G0/G1 phase cell-cycle arrest and apoptosis, and demonstrates anti-proliferative activity in xenograft mice models. ZW-49 can be used for the research of cancer, such as non-small cell lung cancer.

Trastuzumab-DM12 (T-DM21) is an antibody-drug conjugate (ADC). Trastuzumab-DM12 binds to HER2, inhibits HER2 shedding, and mediates antibody-dependent cellular cytotoxicity. Trastuzumab-DM12 is formed by conjugating the antibody Trastuzumab (HY-P9907) with DM-21 (HY-139441). Trastuzumab-DM12 can be used for cancer research.

Disitamab vedotin (RC48) is an antibody-drug conjugate (ADC) comprising a monoclonal antibody against human epidermal growth factor receptor 2 (HER2) conjugated via a cleavable linker to the cytotoxic agent Monomethyl auristatin E (MMAE) (HY-15162), and the drug-linker conjugate for ADC is Deruxtecan (HY-13631E). Disitamab vedotin enhances antitumor immunity.

Pertuzumab, a humanized IgG1 monoclonal antibody, is a HER2 dimerization inhibitor for the treatment of metastatic HER2-positive breast cancer.

Zanidatamab (ZW25) is a humanised, bispecific monoclonal antibody targeting 2 distinct HER2 epitopes (ECD2 and ECD4). Zanidatamab has anti-tumour activity.

Dacomitinib (PF-00299804) is a specific and irreversible inhibitor of the ERBB family of kinases with IC₅₀s of 6 nM, 45.7 nM and 73.7 nM for EGFR, ERBB2, and ERBB4, respectively.

Afatinib (BIBW 2992) dimaleate is an orally active, potent and irreversible dual specificity inhibitor of ErbB family (EGFR and HER2), with IC₅₀ values of 0.5 nM, 0.4 nM, 10 nM and 14 nM for EGFR^wt, EGFR^L858R, EGFR^L858R/T790M and HER2, respectively. Afatinib dimaleate can be used for the research of esophageal squamous cell carcinoma (ESCC), non-small cell lung cancer (NSCLC) and gastric cancer.

Sapitinib (AZD-8931) is a reversible, ATP competitive EGFR inhibitor of with IC₅₀s of 4, 3 and 4 nM for EGFR, ErbB2 and ErbB3 in cells, respectively.

Pyrotinib (SHR-1258) is a potent and selective EGFR/HER2 dual inhibitor with IC₅₀s of 13 and 38 nM, respectively.

Sunvozertinib (DZD9008) is a potent ErbBs (EGFR, Her2, especially mutant forms) and BTK inhibitor. Sunvozertinib shows IC₅₀s of 20.4, 20.4, 1.1, 7.5, and 80.4 nM for EGFR exon 20 NPH insertion, EGFR exon 20 ASV insertion, EGFR L858R and T790M mutations, and Her2 Exon20 YVMA, and EGFR WT A431, respectively (patent WO2019149164A1, example 52).

Canertinib (CI-1033;PD-183805) is a potent and irreversible EGFR inhibitor; inhibits cellular EGFR and ErbB2 autophosphorylation with IC₅₀s of 7.4 and 9 nM. Canertinib is active against vaccinia virus respiratory infection in mice.

CUDC-101 is a potent inhibitor of HDAC, EGFR, and HER2 with IC₅₀s of 4.4, 2.4, and 15.7 nM, respectively. CUDC-101 is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.
