Inosine is a potent primary stimulus of insulin secretion from isolated mouse islets. The inosine-induced insulin secretion was totally depressed during starvation, but was completely restored by the addition of 5mmi-caffeine to the medium and partially restored by the addition of 5mM-glucose. Mannoheptulose (3mg/ml) potentiated the eflect of lOmM-inosine in islets from fed mice. The mechanism ...

Abstract Background Ulcerative colitis is a type of chronic inflammatory bowel disease closely associated with gut microbiota dysbiosis and intestinal homeostasis dysregulation. Barley leaf (BL) has long history use in Traditional Chinese Medicine potential health-promoting effects on functions. However, its mechanism action not yet clear. Here, we explore the modulating roles microbial metabol...

BACKGROUND The first step of the bacterial lifecycle is the germination of bacterial spores into their vegetative form, which requires the presence of specific nutrients. In contrast to closely related Bacillus anthracis spores, Bacillus cereus spores germinate in the presence of a single germinant, inosine, yet with a significant lag period. METHODS AND FINDINGS We found that the initial lag...

BACKGROUND AND PURPOSE Purinergic nucleoside inosine elicits protection and regeneration during various injuries. The purpose of this study was to examine the protective effects of inosine against cerebral ischemia. METHODS Adult Sprague-Dawley rats were anesthetized. Inosine, hypoxathine, or vehicle was administered intracerebroventricularly before transient right middle cerebral artery occl...

A biochemical and cytochemical study has been made of the distribution of ATPase in mature and differentiating phloem cells of Nicotiana tabacum and of the substrate specificity and effects of fixation on enzyme activity. Homogenates of unfixed leaf midveins and midveins fixed in formaldehyde-glutaraldehyde were assayed for enzyme activity by determining the amount of P(i), liberated per millig...

OBJECTIVE Inosine, a break-down product of adenosine has been recently shown to exert inodilatory and anti-inflammatory properties. Furthermore inosine might be a key substrate of pharmacological post-conditioning. In the present pre-clinical study, we investigated the effects of inosine on cardiac function during reperfusion in an experimental model of cardioplegic arrest and extracorporal cir...

The objective of these studies was to determine whether inosine, a precursor of the antioxidant uric acid, can ameliorate hemin-induced oxidative stress. Dietary inclusion of inosine was begun either before or after hemin-induced oxidative stress. Broilers (4 weeks) were divided into four treatment groups (Control, Hemin, Inosine, Hemin/Inosine). Throughout the study control birds (n=10) were i...

Neurogenic detrusor overactivity (NDO) is among the most challenging complications of spinal cord injury (SCI). A recent report by us demonstrated an improvement in NDO in SCI rats following chronic systemic treatment with the purine nucleoside inosine. The objective of this study was to investigate the mechanism of action of inosine underlying improvement of NDO. Male Sprague-Dawley rats under...

Inosine, a breakdown product of adenosine, has recently been shown to exert immunomodulatory and neuroprotective effects. We show here that the oral administration of inosine has antidepressant-like effects in two animal models. Inosine significantly enhanced neurite outgrowth and viability of primary cultured neocortical neurons, which was suppressed by adenosine A1 and A2A receptor agonists. ...

The literature review synthesizes the cardiac cross in immunological activities through adenosine triphosphatase (ATP). Biochemical proton- coupled electron transfer (PCET) is intimately associated with human physiological and pathogenic attributes. motivated by viral pathogens such as SARS-CoV-2 HIV-1, thus structured. organic inorganic chemistries involved PCET will further knowledge on corre...
