| Product name | Dusquetide TFA |
| Description | Dusquetide is a new‑generation innate defense regulator peptide (IDR). It does not directly kill bacteria, but regulates the function of innate immune cells such as neutrophils and macrophages. On one hand, it inhibits excessive inflammatory response and tissue damage; on the other hand, it enhances the body's pathogen clearance ability, achieving a dual immunomodulatory effect of "anti‑inflammation ‑ enhanced defense". It has significant repair and protective effects on oral mucositis and gastrointestinal mucosal injury caused by chemotherapy and radiotherapy, and can also be used for mechanism research of infectious and inflammatory diseases and immunomodulatory peptide development. The trifluoroacetate salt is an HPLC purification intermediate. |

| PEP-SOR1302 | Sorcin-targeted tridecapeptide acetate that reverses tumor multidrug resistance, enhances chemosensitivity and inhibits tumor invasion and metastasis | SOR-C13 specifically binds sorcin (soluble resistance-related calcium-binding protein) highly expressed in tumor cells, interferes with its regulation of intracellular calcium homeostasis, reverses the high expression of drug resistance proteins such as P-glycoprotein, restores the sensitivity of tumor cells to chemotherapeutic drugs, and exerts chemosensitization and multidrug resistance reversal effects; meanwhile, it inhibits tumor cell adhesion, invasion and migration ability by blocking sorcin-mediated metastasis-related signaling pathways, and reduces tumor metastasis and colonization. The acetate form has good physiological compatibility, and combined use with chemotherapeutic drugs can improve efficacy and reduce toxic side effects. | Tumor multidrug resistance, Tumor metastasis research, Chemosensitization, Calcium-binding protein function, Anti-tumor peptides, Targeted drug development | Sorcin (Soluble resistance-related calcium-binding protein); Tumor multidrug resistance pathway; Tumor invasion and metastasis inhibitory pathway |
