Abstract
Geniposide (GE) possesses excellent neuroprotective effects but with poor brain targeting and short half-life. Liposome was considered to have great potential for brain diseases. Therefore, this research aimed to develop a geniposide liposome (GE-LP) as a brain delivery system for cerebral ischemia reperfusion injury (CIRI) therapy and evaluate its characterization, pharmacokinetics, brain targeting, and neuroprotective effects in vivo. Then, a reverse-phase evaporation method was applied to develop the GE-LP and optimize the formulation. Notably, the GE-LP had suitable size, which was 223.8 nm. Subsequently, the pharmacokinetic behavior of GE solution and GE-LP in mice plasma was investigated, and the brain targeting was also researched. The results showed that GE in plasma of GE-LP displayed three folds longer distribution half-life and a higher bioavailability and brain targeting compared to GE solution. In vivo neuroprotective effects was evaluated through the middle cerebral artery occlusion (MCAO) rat model, and GE-LP exhibited a stronger tendency in preventing the injury of CIRI, which can significantly improve neurological deficits. Overall, this study demonstrates GE-LP as a new formulation with ease of preparation, sustained release, and high brain targeting, which has significant development prospects on CIRI; this is expected to improve the efficacy of GE and reduce the frequency of administration.

Ran D, Hong W, Yan W, Mengdie W. Properties and molecular mechanisms underlying geniposide-mediated therapeutic effects in chronic inflammatory diseases. JOURNAL OF ETHNOPHARMACOLOGY 2021; 273:113958. [PMID: 33639206 DOI: 10.1016/j.jep.2021.113958] [Citation(s) in RCA: 31] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/24/2020] [Revised: 01/25/2021] [Accepted: 02/16/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Geniposide (GE) is ubiquitous in nearly 40 species of plants, among which Gardenia jasminoides J. Ellis has the highest content, and has been used ethnopharmacologically to treat chronic inflammatory diseases. As a traditional Chinese medicine, Gardenia jasminoides J. Ellis has a long history of usage in detumescence and sedation, liver protection and cholestasis, hypotension and hemostasis. It is commonly used in the treatment of diabetes, hypertension, jaundice hepatitis, sprain and contusion. As a type of iridoid glycosides extracted from Gardenia jasminoides J. Ellis, GE has many pharmacological effects, such as anti-inflammatory, anti-angiogenesic, anti-oxidative, etc. AIM OF THE REVIEW: In this article, we reviewed the sources, traditional usage, pharmacokinetics, toxicity and therapeutic effect of GE on chronic inflammatory diseases, and discussed its potential regulatory mechanisms and clinical application. RESULTS GE is a common iridoid glycoside in medicinal plants, which has strong activity in the treatment of chronic inflammatory diseases. A large number of in vivo and in vitro experiments confirmed that GE has certain therapeutic value for a variety of chronic inflammation disease. Its mechanism of function is mainly based on its anti-inflammatory, anti-oxidant, neuroprotective properties, as well as regulation of apoptotsis. GE plays a role in the treatment of chronic inflammatory diseases by regulating cell proliferation and apoptosis, realizing the dynamic balance of pro/anti-inflammatory factors, improving the state of oxidative stress, and restoring abnormally expressed inflammation-related pathways. CONCLUSION According to its extensive pharmacological effects, GE is a promising drug for the treatment of chronic inflammatory diseases.

Neurosci Lett 2020; 720:134749. [PMID: 31935433 DOI: 10.1016/j.neulet.2020.134749] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2019] [Revised: 01/03/2020] [Accepted: 01/07/2020] [Indexed: 12/12/2022]
Abstract
OBJECTIVE The aim of this study is to investigate the protective effects as well as the underlying molecular mechanisms of geniposide in APP/PS1 transgenic mice. METHOD APP/PS1 mice were subjected to intragastric administration of geniposide (50 mg/kg/d) for 8 weeks (including a 2-week behavior test). The novel object recognition (NOR) and the Morris water maze (MWM) tests were used for behavioral assessments. Aβ1-40 plaques in mice cortices and hippocampi are visualized with immunohistochemistical staining. ELISA was used to quantify the levels of soluble Aβ1-40 and Aβ1-42 in the hippocampus. Western blot was used to detect p-Akt/Akt, p-mTOR/mTOR and p-4E-BP1/4E-BP1 levels. The relative mRNA levels of Akt, mTOR and 4E-BP1 were quantified using real-time PCR (RT-PCR). RESULTS Geniposide alleviated cognitive impairment by improving the ability of novel object exploration, spatial memory, and reduced the level of Aβ in the brain of APP/PS1 mice. Geniposide possibly regulates mTOR-related proteins through modification of phosphorylation. Geniposide markedly lowered p-mTOR and p-Akt expressions while elevating p-4E-BP1 expression. Geniposide obviously reduced the relative mRNA levels of Akt and mTOR and increased the relative mRNA level of 4E-BP1. CONCLUSION Geniposide is able to alleviate cognitive impairments and cerebral damage in APP/PS1 mice, with its neuroprotective effects likely mediated via modulation of the mTOR signaling pathway.

Abstract
Geniposide is a well-known iridoid glycoside compound and is an essential component of a wide variety of traditional phytomedicines, for example, Gardenia jasminoides Elli (Zhizi in Chinese), Eucommia ulmoides Oliv. (Duzhong in Chinese), Rehmannia glutinosa Libosch. (Dihuang in Chinese), and Achyranthes bidentata Bl. (Niuxi in Chinese). It is also the main bioactive component of Gardeniae Fructus, the dried ripe fruit of Gardenia jasminoides Ellis. Increasing pharmacological evidence supports multiple medicinal properties of geniposide including neuroprotective, antidiabetic, hepatoprotective, anti-inflammatory, analgesic, antidepressant-like, cardioprotective, antioxidant, immune-regulatory, antithrombotic, and antitumoral effects. It has been proposed that geniposide may be a drug or lead compound for the prophylaxis and treatment of several diseases, such as Alzheimer's disease, Parkinson's disease, diabetes and diabetic complications, ischemia and reperfusion injury, and hepatic disorders. The aim of the present review is to give a comprehensive summary and analysis of the pharmacological properties of geniposide, supporting its use as a medicinal agent.
