Liu RJ, He YJ, Liu H, Zheng DD, Huang SW, Liu CH. Protective effect of Lycium barbarum polysaccharide on di-(2-ethylhexyl) phthalate-induced toxicity in rat liver. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2021; 28:23501-23509. [PMID: 33449321 DOI: 10.1007/s11356-020-11990-8] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/14/2020] [Accepted: 12/06/2020] [Indexed: 06/12/2023]
Abstract
Di-(2-ethylhexyl)-phthalate (DEHP) is the most commonly used plasticizer and it has been a ubiquitous environmental contaminant which affects health. The purpose of this study was to investigate the protective effect of the Lycium barbarum polysaccharide (LBP) at dosages of 100, 200, and 300 mg/kg bw on DEHP-induced (3000 mg/kg) toxicity in rat liver through a 28-day animal experiment. The results showed that LBP attenuated oxidative stress slightly by lowering the production of ROS and improving the activity of SOD and GSH-Px in liver and serum of DEHP treatment rats. At the same time, the levels of PXR, CYP450, CYP2E1, CYP3A1, UGT1, and GST were reduced after LBP treatment. Moreover, LBP decreased the mRNA expression of PXR, UGT1, and GST significantly. These findings suggested that LBP might ameliorate DEHP-induced liver injury by down-regulating the expression of PXR in liver, further down-regulating the downstream phase I and II detoxification enzymes, thus reducing the damage caused by DEHP. Therefore, LBP may have the potential to become an auxiliary therapeutic agent as a natural ingredient of health food.

Curr Drug Metab 2020; 21:1060-1067. [DOI: 10.2174/1389200221999201116142742] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2020] [Revised: 10/21/2020] [Accepted: 11/03/2020] [Indexed: 11/22/2022]
Abstract
Background:
Leonurine (Leo), a promising antilipemic agent that has been approved for clinical
trials, is extensively metabolized into bioactive Leonurine-10-O-β-glucuronide (L-10-G) vivo.
Objective:
To explore the effects of breast cancer resistance protein (Bcrp) and multidrug resistance protein 2
(Mrp2) on the disposition of L-10-G.
Methods:
The pharmacokinetics, tissue distribution and intestinal perfusion of Leo were studied by using efflux
transporter gene knockout mouse models. The enzyme kinetics via liver and intestinal microsomes were also examined.
Results:
After intravenous injection with Leo, the AUC0-∞ values of L-10-G in Bcrp1-/- and Mrp2-/- mice were
1.55-fold and 16.80-fold higher, respectively, than those in wild-type FVB mice (P < 0.05). After oral administration,
the AUC0-∞ value of L-10-G showed a 2.82-fold increase in Mrp2-/- mice compared with wild-type FVB
mice (P < 0.05). After gavage with Leo for 10 and 25 min, the bile accumulation of L-10-G in Mrp2-/- mice was
3-fold and 22-fold lower, respectively, than that in wild-type FVB mice (P < 0.05). Besides, the intestinal excreted
amount of L-10-G showed 2.22-fold and 2.68-fold decrease in Bcrp1-/- and Mrp2-/- mice, respectively,
compared with that in wild-type FVB mice (P < 0.05). The clearance of L-10-G decreased in liver microsomes
and increased in intestinal microsomes of Bcrp1-/- and Mrp2-/- mice compared to the wild-type FVB mice (P <
0.05).
Conclusion:
Both Bcrp and Mrp2 are involved in the disposition of L-10-G, and Mrp2 exhibits a superior influence.

Abstract
Despite several advances in percutaneous coronary intervention and the discovery of new drugs, the incidence of myocardial infarction and deaths due to cardiovascular diseases (CVD) has not decreased markedly in China. The quality of life is affected seriously, which further results in great social and family burden. Many drugs, from the century-old aspirin to the newly FDA-approved Byvalson, have been proven to be effective in the treatment and prevention of CVD. As clinically reported, those life-saving drugs still have their side effects in regards to the narrow therapeutic indexes influenced by individual genetic variations. Herba Leonuri, also known as Chinese Motherwort, which are naturally present in plants and traditionally are used for the uterotonic action, postpartum blood stasis, breast pain as well as other gynecological disorders in China for thousands of years. Since the last two decades, our group has reported leonurine, a unique alkaloid found in Herba Leonuri, exhibits various bioactivities such as antioxidant, anti-apoptotic effects, free radical scavenging and anti-inflammatory effects, in addition to improving micro-circulation. These bioactivities are related to the underlying mechanisms of ischemic heart diseases and cardiac fibrosis. Pharmacological studies have proven leonurine to be effective in treating CVD in various ways, particularly ischemic heart diseases. Besides the cardio protective effects, which are similar in the central nervous system, more specifically, inhibited mitochondrial reactive oxygen species production together with the restored mitochondrial function and redox state were observed in middle cerebral artery occlusion rats by leonurine treatment, which strongly reveals its neuroprotective effects and carries a therapeutic potential for recovery and prevention of stroke. Based on their mode of action, we propose that leonurine can be developed as drugs to treat ischemic heart diseases. Taking advantage of the most recent findings in pharmacological research including the effects of low toxicity and good pharmacokinetics characteristics, leonurine has a very attractive prospect of clinical application. Our recent promising pharmacological results may be able to eradicate the barrier hindering its sale on market. In sum, from bench to bedside is no longer a long way for leonurine.
