HER2-targeted peptide H6F	EGFR	Cancer
HER2-targeted peptide H6F is a *HER2* targeting peptide that binds to *HER2* to target breast cancer cells, with the amino acid sequence YLFFVFER. The HER2-targeted peptide H6F can be conjugated with the bifunctional chelating agent hydrazinonicotinamide (HYNIC) for radiolabeling with 99mTc. Single-photon emission computed tomography (SPECT) imaging shows that the labeled HER2-targeted peptide H6F specifically accumulates in HER2-positive MDA-MBA-453 tumor-bearing mice models. The HER2-targeted peptide H6F can be used for tumor molecular imaging studies .

HY-P10648

Herceptide HER2-targeting peptide	EGFR	Cancer
Herceptide (HER2-targeting peptide) is a *HER2*-targeting peptide, and can be further conjugated to the near-infrared fluorescent dye indocyanine green (HY-D0711) (ICG) for developing theranostic agents .

HY-176976

Exatecan-mpGNNG	Drug-Linker Conjugates for ADC	Cancer
Exatecan-mpGNNG (Compound 10a) is the linker-payload component of an antibody-drug conjugate (ADC). Exatecan-mpGNNG is composed of Exatecan (HY-13631), a potent topoisomerase I inhibitor, and the linker .

HY-P11760

HER2-targeted peptide H10	EGFR	Cancer
HER2-targeted peptide H10 is a *HER2*-targeting peptide with a K_d value of 30.4 nM. HER2-targeted peptide H10 specifically accumulates in *HER2*-positive tumor tissues of xenograft mice, when conjugated with nanoparticles. HER2-targeted peptide H10 can be used for studies related to *HER2*-positive breast cancer .

HY-P11761

HYNIC-H10F	EGFR	Cancer
HYNIC-H10F is a conjugate of HER2-targeting peptide H10F and bifunctional chelator HYNIC. HYNIC-H10F can be used in breast cancer-related research .

HY-P11613

DOTA-WC8	EGFR	Cancer
DOTA-WC8 is a *HER2*-targeting peptide probe with a K_D of 61.20 nM. ⁶⁸Ga-labeled DOTA-WC8 serves as a PET imaging agent for the specific identification of HER2-positive breast cancer. DOTA-WC8 is applicable to breast cancer-related research .

HY-P11590

WGYRGFYC	EGFR	Cancer
WGYRGFYC (WC8) is a selective *HER2*-targeting peptide that binds specifically to HER2 by mimicking the antigen-binding site of trastuzumab. The DOTA precursor of WGYRGFYC has a K_D of 61.20 nM for HER2. WGYRGFYC enables specific and highly sensitive detection of HER2 expression in HER2-positive breast cancer cells and tumor tissues, and monitors the dynamic downregulation of HER2 expression. WGYRGFYC rapidly distributes to target tissues and is efficiently cleared from non-target tissues via the kidneys, generating an ideal tumor-to-background ratio in imaging; it is a component of the PET radiotracer Ga-DOTA-WC8. WGYRGFYC exhibits no significant cytotoxicity in breast cancer cells, and can be used for non-invasive imaging diagnosis and therapeutic efficacy evaluation of HER2-positive breast cancer .
