Melanoma is a malignant tumor of melanocytes that is a serious threat to human health. Dermatan sulfate (DS) is a natural glycosaminoglycan. Inspired by the origin of DS, we report a DS-functionalized biomimetic chitosan nanocarrier (DCNP) for melanoma targeted chemotherapy. DS can anchor to the surface of the chitosan nanocarrier (CNP) by forming amide bond. The SN38/DCNP can rapidly release the anti-tumor drug under acidic conditions. The functionalization of DS not only promoted the specific uptake behavior of melanoma cells, but also up-regulated cleaved caspase-3 and PARP promote tumor cell apoptosis. In vivo model, DCNP reduced the non-specific distribution of SN38 in the circulation and other tissues, while shows superior tumor targeting ability. SN38/DCNP significantly inhibit tumor growth and improved the survival rate. Moreover, SN38/DCNP has a milder myelosuppressive effect. The above results indicated that DS could be used as an excellent targeting unit for the treatment of melanoma.
