摘要: In this work, melanin nanoparticle-resveratrol (MNP-RES) nanosystem was excogitated and constructed for the treatment and imaging of folate-induced renal fibrosis (RF) mice model to fulfill the combination of diagnosis and therapeutic. Physicochemical characterization indicated that MNP-RES was a monodisperse spherical framework with a uniform diameter of (18.6±2.7) nm and the drug loading content of RES was 44.8%. The inhibition ratios of reactive oxygen species, such as ·OH,·O2-, ABTS· and DPPH were all greater than 80%. After systemic therapy with MNP-RES, the levels of serum creatinine (SCr) and blood urea nitrogen (BUN) were decreased, and the extent of renal fibrosis was considerably relieved, which was verified by H&E, Masson and terminal-deoxynucleoitidyl transferase mediated nick end labeling (TUNEL) staining. The MNP-RES nanosystem can diagnose and monitor the therapeutic efficacy of RF in real time and noninvasively via photoacoustic/magnetic resonance imaging (PA/MRI) dual-modality imaging, and the MNP-RES diagnostic-therapeutic nanosystem had satisfactory biocompatibility in vivo, which facilitated its future bio-transformation for RF treatment in clinical application.
