Gut Bacterial Species Distinctively Impact Host Purine Metabolites during Aging in Drosophila

iScience, 2020
Summary: Gut microbiota impacts the host metabolome and affects its health span. How bacterial species in the gut influence age-dependent metabolic alteration has not been elucidated. Here we show in Drosophila melanogaster that allantoin, an end product

Allantoin content in lichens depends on anthropopressure level

Ecological Indicators, 2021
Allantoin has been detected in several plant families but only few papers reported its presence in lichens. The 18 from 21 lichen species we tested contained detectable amount of allantoin with a range of 0.005–13.4 mg/g DW.

Allantoin excretion in the rat [PDF]

British Journal of Nutrition, 1973
1. Allantoin excretion was determined in forty-four rats; twenty-four rats were 21 d old and twenty were 90 d old. The animals receivedad lib.for 11 d diets that contained varying amounts of protein from casein and from gluten. Urinary allantoin excretion was determined during the last 3 d of the period.2. The amount of allantoin excreted in both young

Crystal Structure Characterization of Natural Allantoin from Edible Lichen Umbilicaria esculenta

Crystals, 2011
In China, Korea, and Japan, Umbilicaria esculenta is considered as both food and medicinal resources from lichen. In the current study, a prismatic crystal was first isolated from edible lichen U. esculenta via solvent fractionation. The structure of the

Effects of Rhizome Extract of Dioscorea batatas and Its Active Compound, Allantoin, on the Regulation of Myoblast Differentiation and Mitochondrial Biogenesis in C2C12 Myotubes

Molecules, 2018
With the aging process, a loss of skeletal muscle mass and dysfunction related to metabolic syndrome is observed in older people. Yams are commonly use in functional foods and medications with various effects.

Biosynthesis of Radioactive Allantoin.

Experimental Biology and Medicine, 1950
Summary1. A convenient method for the isolation of allantoin from the urine of rats has been developed. 2. The carbon of sodium bicarbonate is not incorporated in the urinary allantoin of rats. This result is in accord with the fact that bicarbonate is incorporated only into position 6 of purines. 3.

Allantoin attenuates deficits of behavioural and motor nerve conduction in an animal model of cisplatin‐induced neurotoxicity in rats

Animal Models and Experimental Medicine, 2019
Background The aim of the present study was to evaluate the neuroprotective effect of allantoin in cisplatin‐induced toxicity in rats. Methods Adult male Wistar rats weighing 160‐200 g were used. Neuropathy was induced by injecting cisplatin (2 mg/kg, ip,

Allantoin eutectics with choline chloride and zinc chloride: interactions and wound healing applications

Journal of Taibah University for Science, 2023
Allantoin eutectics with choline chloride (ACM) and zinc chloride (AZM) are reported. The solid–liquid phase diagram showed the eutectic point in allantoin-rich region (Xallantoin = 0.9) for ACM.

Estimation of allantoin flux using continuous infusion of [¹⁴C]allantoin: sensitivity to plasma loading with unlabelled allantoin [PDF]

British Journal of Nutrition, 2001
Allantoin net flux through the plasma allantoin compartment was determined in sheep given a roughage diet by means of a continuous infusion of [4,5-14C]allantoin for 17 h. Unlabelled allantoin was infused intravenously during the last 7 h of the tracer infusion to increase the allantoin flux by approximately 75 %. When unlabelled allantoin was infused,
