List of anticancerpeptides Anti-cancer peptides (ACPs) represent a rapidly evolving area of cancer research, offering a novel therapeutic approach distinct from traditional chemotherapy. These short chains of amino acids, typically ranging from 10 to 60 residues, are designed to specifically target and combat cancer cells. Their mechanisms of action are diverse, encompassing direct tumor cell destruction, modulation of the immune system to recognize and attack cancer, and interference with crucial cancer cell processes like proliferation and migration. The development of ACPs aims to overcome challenges associated with current cancer treatments, such as drug resistance, tumor heterogeneity, and significant side effects.

Understanding the Mechanisms of Anti-Cancer Peptides

The efficacy of anti-cancer peptides stems from their ability to interact with cancer cells through various pathways. Many ACPs are cationic and amphipathic, allowing them to bind to and disrupt the membranes of cancer cells, leading to cell death作者：AK Tripathi·2022·被引用次数：38—A large number of anti-cancer peptidesshow good immunomodulatory activityby inhibiting the pro-inflammatory responses that assist cancer progression.. This direct cytotoxic effect is a key advantage. Other ACPs function indirectly by modulating the body's immune response. They can stimulate the immune system to identify and eliminate malignant cells or inhibit pro-inflammatory responses that often support cancer progression. Furthermore, ACPs can target specific hallmarks of tumors, such as sustained proliferative signaling, resistance to apoptosis, and metabolic reprogramming, effectively hindering tumor growth and survival.Peptides as multifunctional players in cancer therapy

Classification and Characteristics of ACPs

Anti-cancer peptides can be broadly classified based on their origin and mechanism of action. Some are naturally derived from sources like spider venom or antimicrobial peptides produced by various organisms, while others are synthetically designed. A significant characteristic of many ACPs is their ability to cross cell membranes and reach intracellular targets, a crucial requirement for developing effective anticancer agents.作者：RK Chinnadurai·2023·被引用次数：119—This review presents an updated overview ofdifferent anti-cancer peptides, their mechanisms of action and current production strategies employed for their ... This penetration capability, combined with their inherent potency and specificity, makes them attractive candidates for therapeutic development. Databases like CancerPPD-2.0 are being developed to catalog and analyze the sequences, structures, and experimental techniques associated with these promising compounds.

Advantages Over Conventional Cancer Therapies

Compared to conventional chemotherapy drugs, anti-cancer peptides offer several distinct advantagesDCTPep, the data of cancer therapy peptides. Their high specificity means they can often target cancer cells with greater precision, potentially reducing damage to healthy tissues and minimizing side effects. This molecular specificity, coupled with their multifunctionality, contributes to their therapeutic potential作者：M Xie·2020·被引用次数：288—Anti-cancer peptides (ACPs) area series of short peptides composed of 10–60 amino acidsthat can inhibit tumour cell proliferation or migration.. Furthermore, protein/peptide drugs, including ACPs, are known for their high pharmacological potency and relatively low toxicityAnticancer activities of natural antimicrobial peptides from .... This biocompatibility and efficient therapeutic efficacy present a compelling alternative, particularly for patients who have developed resistance to existing treatments or experience severe adverse reactions.

Current Research and Future Prospects

The field of anti-cancer peptides is marked by ongoing research into their development, delivery, and application. Studies are exploring different anti-cancer peptides, their precise mechanisms of action, and current production strategies. Innovations in delivery systems are also crucial to ensure that these peptides effectively reach their targets within the body. While many promising anti-cancer peptides are still in preclinical or early clinical stages, their potential as targeted therapeutic agents is substantial. The ongoing exploration of their status and future prospects suggests a significant role for ACPs in the evolving landscape of cancer treatment.作者：X Liu·2018·被引用次数：174—Protein/peptide drugs possess unique advantages, such as high pharmacological potency, molecular specificity, multifunctionality, and low toxicity, ...
