Stevioside is a natural non-caloric sweetener. It is one of the steviol glycosides found in stevia, a natural sweetener extract isolated from the leaves of the plant S. rebaudiana. Stevioside has potential applications as a food additive or dietary supplement in diets designed to ameliorate obesity or conditions linked to glucose intolerance, like some forms of diabetes.

Novel insights into the potential role of ion transport in sensory perception in Acanthamoeba
Parasit Vectors 2019 Nov 14;12(1):538.PMID:31727139DOI:10.1186/s13071-019-3785-0.
Background: Acanthamoeba is well known to produce a blinding keratitis and serious brain infection known as encephalitis. Effective treatment is problematic, and can continue up to a year, and even then, recurrence can ensue. Partly, this is due to the capability of vegetative amoebae to convert into resistant cysts. Cysts can persist in an inactive form for decades while retaining their pathogenicity. It is not clear how Acanthamoeba cysts monitor environmental changes, and determine favourable conditions leading to their emergence as viable trophozoites. Methods: The role of ion transporters in the encystation and excystation of Acanthamoeba remains unclear. Here, we investigated the role of sodium, potassium and calcium ion transporters as well as proton pump inhibitors on A. castellanii encystation and excystation and their effects on trophozoites. Results: Remarkably 3',4'-dichlorobenzamil hydrochloride a sodium-calcium exchange inhibitor, completely abolished excystation of Acanthamoeba. Furthermore, lanthanum oxide and Stevioside hydrate, both potassium transport inhibitors, resulted in the partial inhibition of Acanthamoeba excystation. Conversely, none of the ion transport inhibitors affected encystation or had any effects on Acanthamoeba trophozoites viability. Conclusions: The present study indicates that ion transporters are involved in sensory perception of A. castellanii suggesting their value as potential therapeutic targets to block cellular differentiation that presents a significant challenge in the successful prognosis of Acanthamoeba infections.
Solubility and Permeability Improvement of Quercetin by an Interaction Between α-Glucosyl Stevia Nanoaggregates and Hydrophilic Polymer
J Pharm Sci 2019 Jun;108(6):2033-2040.PMID:30653971DOI:10.1016/j.xphs.2019.01.007.
The effect of composite formation between α-glucosyl stevia (Stevia-G) and hydrophilic polymers on solubility and permeability enhancement of quercetin hydrate (QUE) was evaluated. Polyvinylpyrrolidone K-30 (PVP), hydroxypropyl methylcellulose 2910-E (HPMC), and hydroxypropyl cellulose SSL (HPC) were selected as candidate hydrophilic polymers. Fluorescence studies with pyrene and curcumin suggested composite formation occurs between Stevia-G aggregate and polymers. Furthermore, the strength of interaction between Stevia-G aggregate and polymers was as follows: PVP > HPMC > HPC. Evaporated particles (EVPs) of QUE with Stevia-G and polymers showed synergic QUE solubility enhancement. Solubility of QUE from the EVPs was enhanced in the following order: Stevia-G/PVP > Stevia-G/HPMC > Stevia-G/HPC, in accordance with the degree of interaction. Enhanced membrane permeability of QUE from the EVPs of Stevia-G/PVP was confirmed using Caco-2 cells. The amount of QUE that permeated Caco-2 cells from the EVPs of Stevia-G/PVP was 13.7-, 4.7-, and 2.1-fold higher than that of the untreated QUE powder, EVPs of Stevia-G, and EVPs of PVP, respectively. These results indicated that the composite formed by Stevia-G and PVP can dramatically enhance the solubility and membrane permeability of QUE.
