Abstract

The invention discloses a targeted nano drug delivery system co-loaded with DTIC and miRNA-34a and its preparation method and application. DTIC and miRNA‑34a in micelles. The present invention uses amphiphilic polylactic acid-polypeptide micelles as a drug-loading system to construct a targeted nano drug delivery system that co-loads the chemotherapy drug DTIC and the gene drug miRNA-34a, and the polylactic acid-polypeptide micelles mediate DTIC and miRNA-34a Evade RES clearance, effectively deliver DTIC and miRNA‑34a to the cytoplasm, play a synergistic role, inhibit melanoma cell proliferation and promote melanoma cell apoptosis, provide a new method for the treatment of melanoma, and provide a basis for the treatment of other tumors useful reference.

Description

Targeted nano-drug delivery system co-loaded with DTIC and miRNA-34a and preparation method thereof application technical field The invention belongs to the technical field of medicine, relate to the targeted nano drug delivery system of co-loading DTIC and miRNA-34a and its Preparation method and application. Background technique Malignant melanoma (MM) is a highly invasive, highly metastatic, and radiotherapy- and chemotherapy-insensitive malignant tumor Tumor is one of the most common malignant diseases in skin cancer, the 5-year survival rate is less than 5%, and the average median survival time is only 6 months. target There is currently no effective treatment for metastatic malignant melanoma (MMM). Cytotoxic dacarba oxazine (DTIC) for the treatment of metastatic malignant melanoma, however, DTIC is a poorly targeted DNA with strong side effects and a low response rate Alkylated preparations are the main cause of drug resistance, metastasis and recurrence...
