莲心碱具有抗肿瘤活性，CYP3A4 介导的代谢激活和 GSH 消耗增强了莲心碱诱导的细胞毒性。

Neferine has anti-tumor activities , Metabolic activation mediated by CYP3A4 and GSH depletion enhanced Neferine-induced cytotoxicity. Neferine can be helpful to increase the efficacy of DOX and to achieve anticancer synergism by curbing the toxicity. Neferine inhibited high glucose-induced endothelial apoptosis via blocking ROS/Akt/NF-κB pathway, which provides the evidence for using Neferine to treat diabetic vasculopathy. Neferine induced apoptosis in a dose-dependent manner with the hypergeneration of reactive oxygen species, activation of MAPKs, lipid peroxidation, depletion of cellular antioxidant pool, loss of mitochondrial membrane potential, and intracellular calcium accumulation.

Neferine down regulates hypoxia induced NF-κB p65 nuclear translocation and COX-2 expressions. Neferine reduces high-glucose-induced collagen production and inhibits TGF-β1-Smad, ERK and p38 MAPK signaling activation in cardiac fibroblasts. Cardiac fibroblasts (CFs) are cultured in HG medium with varying concentrations of Neferine (1, 2, or 5 μM). CCK-8 assays are carried out at different time points (24, 48, and 72 h). Compared with normal glucose (NG) and osmotic control (OC) treatments, High glucose (30 mM) treatment significantly increases the proliferation of CFs in a time-dependent manner (P<0.05). High glucose (HG)-induced CF proliferation is markedly attenuated by Neferine treatment at either 2 or 5 μM compared with vehicle treatment. However, 1 μM Neferine does not inhibit HG-induced proliferation of CFs. Therefore, 2 and 5 μM Neferine are used in the remaining experiments.

Neferine treatment at both low-dose (60 mg/kg/day by gavage) and high-dose (120 mg/kg/day by gavage) reduces the increment of collagen I, III and TGF-β1 protein expression induced by hyperglycemia.
