Xanthine oxidase inhibitory activity of natural and hemisynthetic flavonoids from Gardenia oudiepe (Rubiaceae) in vitro and molecular docking studies.

Xanthine oxidase (XO), an enzyme widely distributed among mammalian tissues, is associated with the oxidation of xanthine and hypoxanthine to form uric acid. Reactive oxygen species are also released during this process, leading to oxidative damages and to the pathology called gout. Available treatments mainly based on allopurinol cause serious side effects. Natural products such as flavonoids may represent an alternative. Thus, a series of polymethoxyflavones isolated and hemisynthesized from the bud exuda...

Preparation of five high purity iridoid glycosides from Gardenia jasminoides Eills by molecularly imprinted solid-phase extraction integrated with preparative liquid chromatography.

Five iridoid glycosides were prepared using molecularly imprinted solid phase extraction combined with preparative high-performance liquid chromatography. Hydrophilic molecularly imprinted polymers were synthesized using α-1-allyl-2-N-acetyl glucosamine, which introduced an abundance of hydrophilic groups into the polymers. Using molecularly imprinted solid-phase extraction as the sample pretreatment procedure, five iridoid glycosides, gardenoside, geniposide, shanzhiside, geniposidic acid, and genipin-1-O...

Crocin attenuates cyclophosphamide induced testicular toxicity by preserving glutathione redox system.

Chemotherapy induced testicular toxicity is an emerging reason for azoospermia and impotency in males. Cyclophosphamide (CP) is a widely used chemotherapeutic agent to manage neoplastic and non-neoplastic autoimmune diseases. Testicular toxicity along with bladder and hepatotoxicity are its widely reported adverse effects. Crocin (CR) is the digentiobiosyl ester of crocetin, found in the fruits of gardenia (Gardenia jasminoides E.) and dried stigmas of saffron (Crocus sativus L.) possess antioxidant, anti-d...

Can Genipin-coated Sutures Deliver a Collagen Crosslinking Agent to Improve Suture Pullout in Degenerated Tendon? An Ex Vivo Animal Study.

The suture-tendon interface is often the weakest link in tendon-to-tendon or tendon-to-bone repair. Genipin is an exogenous collagen crosslink agent derived from the gardenia fruit that can enhance suture force to failure of the tendon-suture interface. Viable methods for intraoperative clinical delivery of genipin could be of clinical utility, but to our knowledge have not yet been extensively studied.

Microdialysis sampling combined with ultra-high-performance liquid chromatography-tandem mass spectrometry for the determination of geniposide in dialysate of joint cavities in adjuvant arthritis rats.

Microdialysis has been used to detect the concentrations of drugs in tissues. Geniposide (GE), an iridoid glycoside compound, is the main bioactive component of Gardenia jasminoides Ellis fruit. We previously demonstrated that GE could control the activity of cytokines and reduce levels of inflammation in adjuvant arthritis (AA) rats, but the topic of concentration changes over time in the joint synovia of AA is scarcely studied.

Protective effects of geniposide and ginsenoside Rg1 combination treatment on rats following cerebral ischemia are mediated via microglial microRNA‑155‑5p inhibition.

Geniposide, an active component of Gardenia, has been reported to protect against cerebral ischemia in animals. Ginsenoside Rg1, a component of Panax notoginseng, is usually administered in combination with Gardenia for the treatment of acute ischemic stroke; however, there are unknown effects of ginsenoside Rg1 that require further investigation. In the present study, the effects of geniposide and ginsensoide Rg1 combination treatment on focal cerebral ischemic stroke were investigated. For in vivo analy...

Genipin normalizes depression-like behavior induced by prenatal stress through inhibiting DNMT1.

Synthetic antidepressants in current use for the complex etiopathogeneses of depression have slow response and remission as well as various unpleasant side effects. As a result, it is imperative to develop new antidepressants with more effectiveness and less severe side effects. Recent studies demonstrated that genipin, the aglycon of geniposide, extracted from Gardenia jasminoides Ellis has antidepressive effects. However, knowledge regarding the molecular mechanisms of its antidepressant effects remains l...

Genipin inhibits the invasion and migration of colon cancer cells by the suppression of HIF-1α accumulation and VEGF expression.

Hypoxia-inducible factor-1 (HIF-1) and vascular endothelial growth factor (VEGF) play important roles in cancer progression in various cancer cell lines. Although genipin, a constituent of Gardenia fruit, has been shown to have anti-tumor activity, its role in the suppression of HIF-1 and its downstream target genes is not well understood. We examined the effect of genipin on the intracellular level of HIF-1α and extracellular level of VEGF using the colon cancer cell line HCT116. We observed that genipin ...

Effects of Temperature on the Development and Reproduction of Thrips hawaiiensis (Thysanoptera: Thripidae).

Environmental temperature has a significant impact on insect behavior. The present study aimed to determine the effects of temperature on the development, survival, and reproduction of Thrips hawaiiensis (Thysanoptera: Thripidae), an important flower-inhabiting thrips. These effects were evaluated at five constant temperatures (18, 21, 24, 27, and 30°C) on thrips reared in the laboratory on excised Gardenia jasminoides flowers. The developmental durations of egg, first instar, second instar, prepupa, pupa,...

Genipin inhibits allergic responses in ovalbumin-induced asthmatic mice.

Genipin is a natural compound isolated from the fruit of Gardenia jasminoides with various pharmacological effects. In this study, we investigated whether genipin effectively alleviates allergic responses in a murine model of ovalbumin (OVA)-induced asthma. The mice were administered an intraperitoneal injection of OVA on day 0 and 14 to boost the immune response; genipin was then administered from day 18 to 23 by oral gavage. On days 21 to 23, mice were OVA-challenged using am ultrasonic nebulizer, and air...

Geniposide improves repeated restraint stress-induced depression-like behavior in mice by ameliorating neuronal apoptosis via regulating GLP-1R/AKT signaling pathway.

Geniposide (GP), a bioactive iridoid glycoside isolated from Gardenia jasminoides Ellis, as well as an agonist of Glucagon-like peptide-1 receptor (GLP-1R), has been reported to exhibit antidepressant-like effects in several rodent models. However, the underlying mechanisms remain obscure. In this study, we mainly investigated the antidepressant-like effects of GP and explored the possible mechanisms associated with GLP-1R signaling by using the repeated restraint stress (RRS)-induced depression model of mi...
