The preventive effects of cepharanthine, a biscoclaurine alkaloid isolated from Stephania cepharantha Hayata, on the lethality and cell death caused by endotoxin or tumor necrosis factor (TNF)-alpha-induced syndrome in septic shock were investigated. In these experiments, we estimated the survival
Inflammatory cytokines and human immunodeficiency virus type 1 (HIV-1) gp120 are considered to play an important role in the pathogenesis of HIV-1-associated CNS disorders. These substances are produced predominantly by HIV-1-infected or activated macrophages and microglia in the brain and induce
Dendritic cells (DCs) are specialized antigen presenting cells that connect innate and adaptive immunity. DCs are considered as a major target for controlling excessive immune responses. In this study, the effect of cepharanthine (CEP), a biscoclaurine alkaloid isolated from Stephania cepharantha
Cepharanthine (Ce) is a biscoclaurine alkaloid extracted from Stephania cepharantha Hayata. In our previous study, Ce significantly enhanced thermosensitivity and thereby reduced thermotolerance in vitro, and intra-peritoneal injection of Ce slightly enhanced thermosensitivity in vivo. In the
Tetrandrine, the active principle of Stephania tetrandra radix extracts, has broad pharmacological activity, including effects on the cardiovascular system: it has been shown to reduce the size of acute myocardial infarction in rats undergoing coronary vessel ligation and to improve heart lesions in
The antihyperglycemic activities of extracts of boiogito (BOT) and bofutsushosan (BTS) were investigated in streptozotocin-induced (STZ)-diabetic mice. BOT extract containing Stephania tetrandra S. MOORE root (stephania), has more potent antihyperglycemic activity than BOT extract containing
Cepharanthin (CEP) is a biscoclaurine alkaloid extracted from Stephania cepharantha Hayata. CEP is reported to inhibit drug resistance by inhibiting P-glycoprotein, a drug efflux pump, and recently to induce apoptosis. In the present study, we examined the effects of CEP as an inhibitor of
Silica-induced lung injury and the development of silicosis is one of the major occupational diseases. Accumulation and deposition of respirable dust containing silica mineral particles in the lung produces chronic lung disease characterized by granulomatous and fibrotic lesions. Knowledge of
Tetrandrine is one of the major active ingredients in Menispermaceae Stephania tetrandra S. Moore, and has specific therapeutic effects in ischemic cerebrovascular disease. Its use in vascular dementia has not been studied fully. Here, we investigated whether tetrandrine would improve behavioral and
Macrophages are important in inflammation through the production of various proinflammatory mediators. β‑glucan is a polymer of glucose, which is produced by numerous different organisms, including fungi, and acts as a trigger for the induction of inflammatory responses. Tetrandrine (TET), a
Tetrandrine (TET), a bis-benzylisoquinoline alkaloid from the root of Stephania tetrandra, is known to possess antitumor activity in various malignant neoplasms. However, the precise mechanism of TET-mediated immune modulation remains to be clarified. One of the possible mechanisms for its
The antitumor potential of Cepharanthin was re-evaluated. Cepharanthin, a biscoclaurin alkaloid extracted from Stephania cepharantha Hayata, dose-dependently reduced the viable cell number of both normal and tumor cells, showing no tumor-specific cytotoxic action. Cepharanthin synergistically
Background: Diabetic nephropathy (DN) is the leading cause of morbidity and mortality in diabetic patients. Tetrandrine (Tet), a bisbenzylisoquinoline alkaloid isolated from the roots of Stephania tetrandra, possesses
We investigated the anti-fibrotic mechanism of tetrandrine, a bisbenzylisoquinoline alkaloid from the Chinese herb, Stephania tetrandra, on the immortalized HSC-T6 rat hepatic stellate cell line. Tetrandrine (0.39-50μM) dose- and time-dependently inhibited HSC-T6 cell viability within 24h and
BACKGROUND
Anti-inflammation strategies are one of the proposed therapeutic approaches to hepatic fibrosis. Tetrandrine (C(38)H(42)O(8)N(2), molecular weight: 622; Tet), an alkaloid isolated from the Chinese medicinal herb Stephania tetrandra, has been shown to exert anti-inflammatory activity in
