Leveraging the inherent specificity and biological activity of peptides, researchers are developing novel approaches to target cancer cells, modulate the immune system, and deliver therapeutic agents with greater precision.作者：L Wang·2022·被引用次数：2145—This review summarizes the efforts and achievements inpeptidedrug discovery, production, and modification, and theircurrentapplications. This field combines the understanding of molecular biology with advanced drug development, offering promising avenues for combating various forms of cancer and addressing challenges like treatment resistance.
Peptides, short chains of amino acids, are naturally occurring molecules with diverse biological functions. In the context of cancer, they are being explored for their ability to interact with specific cellular targets, inhibit tumor growth, and enhance the body's own immune response against cancer cells.作者：NTT Nhàn·2023·被引用次数：107—Abstract:Peptide-based strategies have received an enormous amount of attention because of their specificity and applicability. Their small size and high specificity allow them to bind to receptors on cancer cells or other molecules involved in cancer progression. This targeted action can lead to more effective treatment with potentially fewer side effects compared to traditional systemic therapies like chemotherapy.Cancer Treatment Using Peptides: Current Therapies and ...
Current research highlights several key ways peptides are used in cancer treatment:
* Tumor Targeting Agents: Peptides can be designed to specifically bind to receptors that are overexpressed on cancer cells. This allows for the targeted delivery of cytotoxic drugs or imaging agents directly to the tumor site, a strategy known as peptide-drug conjugation or peptide receptor radionuclide therapy. This approach aims to maximize therapeutic impact while minimizing damage to healthy tissues.
* Immunomodulation: Some peptides can stimulate or regulate the immune system to recognize and attack cancer cells. This is particularly relevant in the growing field of cancer immunotherapy, where peptides can act as vaccines or enhance the activity of immune cells.
* Inhibition of Cancer Cell Growth and Spread: Certain peptides can interfere with essential processes that cancer cells rely on for survival, proliferation, and metastasis2021年8月30日—This white paper discusses the potential use of peptides as anticancer drugs highlightingcurrent scenario and future prospects.. This can include inhibiting angiogenesis (the formation of new blood vessels that feed tumors) or preventing cancer cells from anchoring and multiplying.
* Drug Delivery Systems: Peptides can be incorporated into nanoparticles or other drug delivery systems to improve the stability, targeting, and release of anticancer drugs.
While the field is rapidly advancing, a number of peptide-based drugs have already been approved or are in various stages of clinical trials for cancer treatment. These include peptide hormones used in endocrine therapy for hormone-sensitive cancers, as well as novel peptide therapeutics designed for targeted delivery or immune modulation.
Approved peptide drugs have demonstrated efficacy in treating specific cancers. For instance, peptide receptor radionuclide therapy (PRRT) uses radiolabeled peptides to target tumors expressing specific receptors, delivering radiation directly to cancer cells. This has shown significant success in treating neuroendocrine tumors.Peptides in cancer research
Beyond approved treatments, numerous peptides are undergoing preclinical and clinical investigation. These range from small molecules designed to block specific signaling pathways to complex peptide conjugates and immunotherapies.Peptide-Based Agents for Cancer Treatment The "current scenario and future prospects" in this area are marked by continuous innovation and a growing pipeline of potential treatments.
The advantages of using peptides in cancer treatment are numerous. Their high specificity can lead to improved efficacy and reduced off-target toxicityPeptide Therapeutics: Current Status And Future Directions. They are generally easier to synthesize and modify than larger protein-based drugs, allowing for greater versatility in drug design. Furthermore, their low immunogenicity can be beneficial for repeated dosing.
However, challenges remain. Peptides can be susceptible to degradation by enzymes in the body, which can limit their duration of action and bioavailability. Developing effective delivery systems and formulations to overcome these limitations is a key area of research. Additionally, the cost of developing and manufacturing complex peptide-based therapies can be a factor.
The future of peptide-based cancer treatment is bright, with ongoing research focused on several key areas:
* Personalized Medicine: Tailoring peptide therapies to an individual's specific tumor characteristics and genetic profile.
* Combination Therapies: Integrating peptide therapeutics with existing treatments like chemotherapy, immunotherapy, and radiation to achieve synergistic effects.
* Advanced Delivery Systems: Developing novel methods to enhance peptide stability, targetability, and cellular uptake, such as peptide-drug conjugates and targeted nanoparticlesPeptide drugs: a new direction in cancer immunotherapy.
* New Modes of Action: Discovering and developing peptides that target novel cancer pathways or exploit unique vulnerabilities of cancer cells.
* Peptide Vaccines: Designing peptide-based vaccines to prime the immune system to recognize and attack cancer cells, potentially preventing recurrence or treating existing disease.
The ongoing advancements in understanding cancer biology and peptide chemistry suggest that peptide therapeutics will play an increasingly vital role in the oncologist's toolkit. The ability of peptides to precisely target cancer cells and modulate biological responses offers a powerful strategy to improve patient outcomes and combat the complexities of cancer.
