Abstract

Timosaponin BII (TBII), a major steroidal saponin isolated from Anemarrhena asphodeloides Bge., displays a variety of promising pharmacological activities, such as neuroprotection, enhancement of learning and memory, vascular protection and inhibition of platelet aggregation; therefore, it has been developed as a pharmaceutical for prevention or treatment of dementia. Given the safety concerns surrounding timosaponins and the absence of studies on the safety of TBII, the potential toxicity of TBII was evaluated in toxicity and toxicokinetic studies in rats. In the acute oral toxicity study, loose stools were observed in rats receiving 4000 mg/kg, and the symptoms recovered within 1 day. In the 28-day repeated-dose oral toxicity and toxicokinetic study, rats receiving 540 mg/kg showed loose stools and a slight deceleration of body weight growth in both sexes, and the females also showed a slight decrease in food consumption. Moreover, urinalysis indicated reversible treatment-related toxicity in rats receiving 540 mg/kg. The toxicokinetic study demonstrated a dose-dependent increase in systematic exposure to TBII after 28 successive days of oral treatment with TBII. The accumulation coefficients of TBII were 4.35, 1.70 and 1.81, respectively, in rats that received 60, 180 and 540 mg/kg. The no-observed-adverse-effect level (NOAEL) is proposed to be 180 mg/kg.

Abstract

Anemarrhena asphodeloides Bunge is a traditional Chinese medicine. The timosaponin BII is one of the most abundant and widely studied active ingredients in Anemarrhena asphodeloides Bunge. Related studies have shown that timosaponin BII has potential value for development and further utilization. The protective effect of timosaponin BII on islet β cells under type 2 diabetes was investigated in the glycolipid toxic INS-1 cell model and possible biomarkers were explored by lipidomics analysis. Timosaponin BII was isolated from Anemarrhena asphodeloides Bunge by polyamide resin and Sephadex LH-20. Then, the glycolipid toxicity INS-1 cell model was established to investigate the protective effect of timosaponin BII. The results showed that timosaponin BII could significantly influence the levels of malondialdehyde (MDA) and glutathione (GSH), thereby restoring the insulin secretion ability and cell viability of model cells. Lipidomics analysis was combined with multivariate statistical analysis for marker selection. The four most common pathological and pharmacological lipid markers were phosphatidylserine (PS), suggesting that timosaponin BII had protective effects on model cells related to the reduction oxidative stress and macrophage inflammation. RAW264.7 macrophages were stimulated by LPS to establish a model of inflammation and study the effect of timosaponin BII on the nodes of NOD-like receptor P3 (NLRP3) inflammasome pathway in the model cells. In conclusion, timosaponin BII may have the effect of protecting INS-1 pancreatic β cells through reducing IL-1β (interleukin-1β) production by inhibiting the NLRP3 inflammasome in macrophage and restoring the insulin secretion ability and cell viability by reducing oxidative stress.

Abstract

Peroxide and oxygen free radicals are some of the causes of oxidative stress in brain tissue, and could lead to the change of brain structure and function. In addition, oxidative damage is one of the most important causes of the aging of the vast majority of tissues. The aim of this study is to investigate the protective effect of timosaponin BII on oxidative stress damage of PC12 induced by H2 O2 using metabolomics based on the UHPLC-Q-TOF-MS technique. Partial least-squares discriminant analysis method was used to identify 35 metabolites as decisive marker compounds in a preliminary interpretation of the mechanism of the antioxidative effect of timosaponin BII. The majority of these metabolites are involved in the glutathione metabolism, amino acid metabolism, sphingolipid and glycerophospholipid metabolism. Our results suggest that timosaponin BII demonstrates systematic antioxidant effects in the PC12 oxidative damage cell model via the regulation of multiple metabolic pathways. These findings provide insight into the pathophysiological mechanisms underlying oxidative stress damage and suggest innovative and effective treatments for this disorder, providing a reliable basis for the development of novel therapeutic target in timosaponin BII treatment of oxidative stress.
