Peptide Drug Development Services

Brain tumor peptide drugs are an innovative therapeutic approach. They achieve precise treatment by targeting specific receptors or antigens on the surface of brain tumor cells. Alfa Cytology is dedicated to developing these peptide drugs. Utilizing advanced design and synthesis technologies, coupled with rigorous in vitro and in vivo pharmacodynamic evaluations, our research team provides clients with one-stop services from peptide discovery to drug optimization.

Introduction to Peptide Drug of Brain Tumors

Brain tumor peptide drugs are a highly innovative therapeutic approach that precisely target malignant cells by focusing on specific receptors or antigens on the surface of brain tumor cells. Due to their small molecular weight, peptides have excellent blood-brain barrier penetration and low immunogenicity, allowing them to more effectively reach lesion areas within the central nervous system. Furthermore, these peptide drugs can be customized to improve their stability and affinity, enhancing their effectiveness in treating brain tumors.

Mechanisms of Action of Peptide Drugs for Brain Tumors

• Anti-Cancer Peptides: These peptides exert direct cytotoxic effects on tumor cells through various mechanisms, such as inducing apoptosis in tumor cells or disrupting cell membranes.
• Peptide Drugs Targeting Cell Surface Receptors: These peptides can specifically bind to certain receptors on the surface of brain tumor cells, thereby blocking signaling pathways and inhibiting the proliferation and growth of tumor cells.
• Interfering Peptides: These peptides primarily function by disrupting specific proteins or signaling pathways within tumor cells. For example, they can prevent interactions between key proteins or interfere with the normal progression of the cell cycle, thus inhibiting the growth and proliferation of tumor cells.
• Tumor-Homing Peptides: These peptides possess the property of actively accumulating in tumor tissues, enabling precise delivery of drugs to brain tumor sites. This increases the concentration of the drug within tumor tissues, enhances therapeutic effects, and simultaneously reduces side effects on normal tissues.
