Both the incidence and prevalence of ulcerative colitis (UC) are increasing throughout the world. Neferine, a natural alkaloid, demonstrated a variety of biological activities. In this study, the anti-inflammatory effect of neferine was investigated. Raw264.7 cells were stimulated with lipopolysaccharide (LPS) or LPS plus Z-VAD-fmk (Z-VAD). The inhibitory effect of neferine on secretion of nitrite, cytokines tumor necrosis factor alpha (TNF-[Formula: see text]) and interleukin 6 (IL-6), expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) was determined. The protective effect of neferine was investigated in dextran sulfate sodium (DSS)-induced UC mouse model. Neferine significantly inhibited LPS and LPS plus Z-VAD induced secretion of nitrite, cytokines, and expression of iNOS and COX-2. Oral administration of neferine (10[Formula: see text]mg/kg and 25[Formula: see text]mg/kg) significantly reduced DSS-induced mouse weight loss, decreased disease activity index (DAI) scores, improved colon pathological changes, and decreased plasma cytokines. In addition, neferine significantly inhibited the protein expression of iNOS, COX-2, receptor-interacting protein 1 (RIP1), RIP3, mixed lineage kinase domain-like protein (MLKL), and increased the protein expression of caspase-8 in colon tissues. These data suggest that neferine was a potent anti-inflammatory agent against LPS and DSS induced inflammation both in vitro and in vivo.

This article recapitulates the existing in vitro and in vivo studies focusing on the effects of neferine-an alkaloid derivative of lotus plant, in various disease models and its effects on key signaling molecules. The review also compiles a large number of research studies that demonstrate methods for isolation and extraction, biosynthetic pathway, pharmacological activity and mode of action of neferine and their underlying mechanisms at cellular level. Neferine is a unique bis-benzylisoquinoline alkaloid that possesses a number of therapeutic effects such as anti-cancer, anti-diabetic, anti-aging, anti-microbial, anti-thrombotic, anti-arrhythmic, anti-inflammatory and even anti-HIV. It also enhances the anti-cancer properties of other anti-cancer drugs like cisplatin, adriamycin, taxol, etc. It is also reported to reverse chemo-resistance and enhance sensitivity of the cancer cells towards anti-cancer drugs. The underlying mechanisms for its activities mainly include apoptosis, autophagy and G1 arrest. Neferine protects them against the effect of drugs like cisplatin. The therapeutic properties of neferine is widely diverse, while it shows toxicity to cancer it also shows cyto-protective effects against cardio-vascular diseases, pulmonary disease, and is also effective against Alzheimer’s disease and elicits anti-oxidative effect in many cellular systems. This article thus is the first ever attempt to review the therapeutic activities of neferine established in in vitro and in vivo models and to compile all the fragmented data available on the omnipotent activities of neferine.

Neferine has long been recognized as a medicinal herbal ingredient with various physiological and pharmacological activities. Although previous studies have reported its antithrombotic effect, the underlying mechanisms have not been thoroughly investigated. Since platelets play a key role in thrombosis, we investigated the effects of neferine on human platelet function and the potential mechanisms. Platelet aggregation, adhesion and spreading were performed to investigate the effect of neferine on inhibition of platelet function. Flow cytometry was used to determine platelet alpha granule secretion and integrin IIb/IIIa activation, as detected by CD62P (P-selectin) expression, PAC-1 and fibrinogen binding. Western blotting was utilized to investigate the effect of neferine on intracellular signaling of activated platelet. We found that neferine significantly suppressed platelet aggregation and remarkably promoted the dissociation of platelet aggregates induced by collagen, thrombin, U46619, ADP and adrenaline in a dose-dependent manner. Flow cytometry analysis showed that neferine inhibited thrombin-induced platelet P-selectin expression, PAC-1 and fibrinogen binding. In addition, neferine reduced the adhesion of human platelets on coated collagen under both static and shearing condition at an arterial shear rate of 40 dyne/cm2. Neferine also inhibited the spreading of human platelets on immobilized fibrinogen. Western blot analysis showed that neferine inhibited PI3K activation, and decreased the levels of phosphorylation of Akt, GSK3β and p38 MAPK in platelets. In summary, neferine has the potential to be an antiplatelet and antithrombotic agent by inhibiting the PI3K-Akt-GSK3β/p38 MAPK signaling pathway.
