Thymopolypeptides combined with matrine type alkaloids suppress HBV replication.[Pubmed: 28879743]

METHODS AND RESULTS:
To investigate the antiviral effect of thymopolypeptides combined with 4 kinds of matrine type alkaloids on HepG2.2.15 cells, oxymatrine, sophocarpidine, Sophocarpine, and sophoridine (at concentration of 0.2 mmol•L⁻¹ respectively) were respectively combined with thymopolypeptides (0.025, 0.1 g•L⁻¹), and after 48 h and 72 h treatment on HepG2.2.15 cells, the cells and supernatants were collected. The cells activity in various groups was determined by CCK-8 method to evaluate the toxic effects of the drugs on HepG2.2.15 cells. Enzyme linked immunosorbent assay (ELISA) was used to determine HBeAg and HBsAg levels in cellular supernatants. HBV DNA levels in cellular supernatants andcells were quantified with fluorogenic quantitative PCR method; and the expression level of IFN-α in supernatants was detected with CBA method. The results indicated that single thymopolypeptides at 0.025-0.4 g•L⁻¹ had no toxicity to cells. Thymopolypeptides in this concentration range combined with 0.2 mmol•L⁻¹ matrine type alkaloids also had no toxicity to cells. Anti-HBV activity of drug combination was better than that of alkali or thymopolypeptides alone. Thymopolypeptides at 0.025 g•L⁻¹ had better inhibitory effect than thymopolypeptides at 0.1 g•L⁻¹ on intracellular HBV DNA expression, but the inhibitory effect on supernatant HBeAg level was on the contrary. Anti-HBV activity was similar between alkaloids combined with 0.1 g•L⁻¹ and alkaloids combined with 0.025 g•L⁻¹. There was no statistical difference in anti-HBV effect between various combined groups (P<0.05). In general, 72 h anti-HBV effect was better than 48 h anti-HBV effect (P<0.05). The expression of IFN-α was increased after drug combination, with positive correlation to the changes of other four indicators (P<0.05).
CONCLUSIONS:
In conclusion, oxymatrine, sophocarpidine, Sophocarpine and sophoridine combined with thymopolypeptides could inhibit HBsAg and HBeAg secretion in HepG2.2.15 cells and HBV DNA replication, and further promote the antiviral effect by promoting the expression of IFN-α.

Sophocarpine attenuates toll-like receptor 4 in steatotic hepatocytes to suppress pro-inflammatory cytokines synthesis.[Pubmed: 25089018 ]
Sophocarpine, a tetracyclic quinolizidine alkaloid derived from Sophora alopecuroides L., has been documented that it can suppress pro-inflammatory cytokines synthesis in alleviating nonalcoholic steatohepatitis (NASH) in vivo. Toll-like receptor 4 (TLR4) is a pattern recognition receptor whose activation results in the production of several pro-inflammatory cytokines. It has been reported that TLR4 is upregulated in nonalcoholic fatty liver disease and plays an important role in the pathogenesis of NASH. This study aimed to examine the changes of TLR4 and its signaling pathways in Sophocarpine's anti-inflammatory process on experimental NASH in vitro.
METHODS AND RESULTS:
Primary hepatocytes were isolated, and oleic acid-induced steatosis model was established. Cell Counting Kit-8 assay was used to detect the number of metabolically active mitochondria and viable cells. Immunocytochemistry analysis was applied to evaluating pro-inflammatory cytokines synthesis. Total RNA and protein were extracted for real-time polymerase chain reaction and Western blot detection. Enhanced expression of TLR4 was observed in oleic acid-induced steatotic hepatocytes. Sophocarpine suppressed pro-inflammatory cytokines synthesis and reduced the expression of TLR4 in steatotic hepatocytes. Expression of TLR4 and pro-inflammatory cytokines recovered after Sophocarpine was removed. Moreover, Sophocarpine restrained the activation of nuclear factor-kappaB (NF-κB), c-Jun-N-terminal kinase (JNK), and Extracellular regulated protein kinases (ERK) signaling pathways in the anti-inflammatory process.
CONCLUSIONS:
Sophocarpine could decrease the expression of TLR4 in steatotic hepatocytes and suppress pro-inflammatory cytokines synthesis. NF-κB, JNK, and ERK signaling pathways were important workable downstream pathways.

Sophocarpine attenuates wear particle-induced implant loosening by inhibiting osteoclastogenesis and bone resorption via suppression of the NF-κB signaling pathway in a rat model.[Pubmed: 29130485 ]
Aseptic prosthesis loosening, caused by wear particles, is one of the most common causes of arthroplasty failure. Extensive and over-activated osteoclast formation and physiological functioning are regarded as the mechanism of prosthesis loosening. Therapeutic modalities based on inhibiting osteoclast formation and bone resorption have been confirmed to be an effective way of preventing aseptic prosthesis loosening. In this study, we have investigated the effects of Sophocarpine (SPC, derived from Sophora flavescens) on preventing implant loosening and further explored the underlying mechanisms.
METHODS AND RESULTS:
The effects of SPC in inhibiting osteoclastogenesis and bone resorption were evaluated in osteoclast formation, induced in vitro by the receptor activator of NF-κB ligand (RANKL). A rat femoral particle-induced peri-implant osteolysis model was established. Subsequently, micro-CT, histology, mechanical testing and bone turnover were used to assess the effects of SPC in preventing implant loosening. In vitro, we found that SPC suppressed osteoclast formation, bone resorption, F-actin ring formation and osteoclast-associated gene expression by inhibiting NF-κB signalling, specifically by targeting IκB kinases. Our in vivo study showed that SPC prevented particle-induced prosthesis loosening by inhibiting osteoclast formation, resulting in reduced periprosthetic bone loss, diminished pseudomembrane formation, improved bone-implant contact, reduced bone resorption-related turnover and enhanced stability of implants. Inhibition of NF-κB signalling by SPC was confirmed in vivo.
CONCLUSIONS:
SPC can prevent implant loosening through inhibiting osteoclast formation and bone resorption. Thus, SPC might be a novel therapeutic agent to prevent prosthesis loosening and for osteolytic diseases.

Targeting miR-21 with Sophocarpine Inhibits Tumor Progression and Reverses Epithelial-Mesenchymal Transition in Head and Neck Cancer.[Pubmed: 28571917 ]
A major challenge for cancer chemotherapy is the development of safe and clinically effective chemotherapeutic agents. With its low toxicity profile, Sophocarpine (SC), a naturally occurring tetracyclic quinolizidine alkaloid derived from Sophora alopecuroides L, has shown promising therapeutic properties, including anti-inflammatory, anti-nociceptive, and antivirus activities. However, the antitumor efficacy of SC and its underlying mechanisms have not been completely delineated.
METHODS AND RESULTS:
In the present study, the inhibitory effect of SC on head and neck squamous cell carcinoma (HNSCC) progression and possible mechanisms for this effect involving microRNA-21 (miR-21) regulation were investigated. By cell viability, Transwell, and wound healing assays, we show that SC effectively inhibited proliferation, invasion, and migration of HNSCC cells. Moreover, SC exerted its growth-inhibitory effect via the downregulation of miR-21 expression by blocking Dicer-mediated miR-21 maturation. Furthermore, SC treatment led to the increased expression of PTEN and p38MAPK phosphorylation as well as the reversal of epithelial-mesenchymal transition (EMT), which was rescued by ectopic expression of miR-21 in cells. Notably, SC dramatically repressed tumor growth without observable tissue cytotoxicity in a mouse xenograft model of HNSCC.
CONCLUSIONS:
Our findings offer a preclinical proof of concept for SC as a leading natural agent for HNSCC cancer therapy.

Sophocarpine Protects Mice from ConA-Induced Hepatitis via Inhibition of the IFN-Gamma/STAT1 Pathway.[Pubmed: 28377718 ]
Sophocarpine is the major pharmacologically active compound of the traditional Chinese herbal medicine Radix Sophorae Subprostratae which has been used in treating hepatitis for years in China. It has been demonstrated that Sophocarpine exerts an activity in immune modulation and significantly decreases the production of inflammatory cytokines. However, the protective effects of Sophocarpine in T cell-dependent immune hepatitis remained unknown.
METHODS AND RESULTS:
The aim of this study was to determine the protective effects and pharmacological mechanisms of Sophocarpine on Concanavalin A (ConA)-induced hepatitis, an experimental model of T cell-mediated liver injury. BALB/C mice were pretreated with Sophocarpine or Bicyclol for five consecutive days. Thirty minutes after the final administration, the mice were injected with 15 mg⋅kg-1 of ConA intravenously. The results indicated that pretreatment with Sophocarpine significantly ameliorated liver inflammation and injury as evidenced by both biochemical and histopathological observations. Moreover, in Sophocarpine-pretreated mice, liver messenger RNA expression levels of chemokines and adhesion molecules, such as macrophage inflammatory protein-1α, CXC chemokine ligand 10, and Intercellular adhesion molecule-1, were markedly reduced. Further studies revealed that Sophocarpine significantly downregulated the expression of T-bet via inhibition of signal transducers and activators of transcription1 (STAT1) activation and overexpression of suppressor of cytokine signaling1, inhibiting the activation of Th1 cells and the expression of Interferon-γ (IFN-γ). Altogether, these results suggest new opportunities to use Sophocarpine in the treatment of T cell-mediated liver disease.
CONCLUSIONS:
In summary, Sophocarpine could attenuate ConA-induced liver injury, and the protective effect of Sophocarpine was associated with its inhibition effect of pro-inflammatory cytokines, chemokines, and the IFN-γ/STAT1 signaling pathway.
