HER-2 Positive Breast Cancer

HER2-positive breast cancer is a subtype of breast cancer characterized by overexpression of the human epidermal growth factor receptor 2 (HER2) protein, which promotes rapid cancer cell growth. It tends to be more aggressive, grow faster, and has a higher risk of recurrence compared to HER2-negative breast cancer. Approximately 20-30% of breast cancers are HER2-positive. Common signs include a new lump or thickening in the breast, changes in nipple appearance such as inversion, and alterations in breast size or shape. The disease is associated with increased tumor progression and metastasis potential, making targeted therapies essential for effective treatment.

    Metformin 657-24-9 99.98%
    Metformin (1,1-Dimethylbiguanide) inhibits the mitochondrial respiratory chain in the liver, leading to AMPK activation and enhancing insulin sensitivity, and can be used in the study of type 2 diabetes. Metformin exerts central glucose-lowering effects by inhibiting Ras-related protein 1 (Rap1) in SF1 hypothalamic neurons. Metformin also inhibits liver oxidative stress, nitrosative stress, inflammation, and apoptosis caused by liver ischemia/reperfusion injury. In addition, Metformin regulates the expression of autophagy-related proteins by activating AMPK and inhibiting the mTOR signaling pathway, thereby inducing tumor cell autophagy and inhibiting the growth of renal cell carcinoma in vitro and in vivo.

    DL149
    DL149 is a component of an antibody-drug conjugate (ADC) formed by conjugating the eIF4A inhibitor FD236 (HY-186186) with an ADC linker, and exhibits potential antitumor activity.

After internalization into cells, it releases the eIF4A inhibitor payload. DL149 irreversibly blocks the mRNA translation process in tumor cells, thereby inhibiting tumor cell proliferation and inducing their death. DL149 exhibits in vivo antitumor activity in the SK-OV-3 xenograft tumor model, and can be used for the research of HER2-positive solid tumors.
