Reformulation of etoposide with solubility-enhancing rubusoside.[Pubmed:22698860]
Int J Pharm. 2012 Sep 15;434(1-2):453-9.
Etoposide (ETO), a widely used anti-cancer drug, is constrained by its low aqueous solubility and by side effects from both the drug and its solubilizing excipients. In this study, a recently discovered natural solubilizer Rubusoside (RUB) was used to achieve the solubilization of ETO. Dynamic light scattering and freeze-fracture transmission electron microscopy studies showed that ETO and RUB formed ETO-RUB nanoparticles ( approximately 6 nm in diameter). The powder of ETO-RUB nanoparticles was completely reconstitutable in water and remained stable in this solution at 25 and 37 degrees C for at least 24h. Under other physiologic conditions, ETO solution was clear and free of precipitation at 25 degrees C, but underwent various structural transformations. In PBS and simulated intestinal fluid, RUB-solubilized ETO underwent epimerization and equilibrated to cis-ETO. In simulated gastric fluid, RUB-solubilized ETO degraded to 4'-demethylepipodophyllotoxin-beta-d-glucoside and 4'-demethylepipodophyllotoxin. Higher temperatures favored epimerization or degradation. Furthermore, a side-by-side comparison with DMSO-solubilized ETO confirmed that the RUB-solubilized ETO showed no significant differences in cytotoxicity in colon, breast and prostate cancer cell lines. RUB effectively solubilized and stabilized etoposide, which sets the stage for further toxicology, bioavailability, and efficacy investigations.
Production of rubusoside from stevioside by using a thermostable lactase from Thermus thermophilus and solubility enhancement of liquiritin and teniposide.[Pubmed:25152415]
Enzyme Microb Technol. 2014 Oct;64-65:38-43.
Solubility is an important factor for achieving the desired plasma level of drug for pharmacological response. About 40% of drugs are not soluble in water in practice and therefore are slowly absorbed, which results in insufficient and uneven bioavailability and GI toxicity. Rubusoside (Ru) is a sweetener component in herbal tea and was discovered to enhance the solubility of a number of pharmaceutically and medicinally important compounds, including anticancer compounds. In this study, thirty-one hydrolyzing enzymes were screened for the conversion of stevioside (Ste) to Ru. Recombinant lactase from Thermus thermophiles which was expressed in Escherichia coli converted stevioside to Rubusoside as a main product. Immobilized lactase was prepared and used for the production of Rubusoside; twelve reaction cycles were repeated with 95.4% of Ste hydrolysis and 49 g L(-1) of Ru was produced. The optimum Rubusoside synthesis yield was 86% at 200 g L(-1), 1200 U lactase. The purified 10% Rubusoside solution showed increased water solubility of liquiritin from 0.98 mg mL(-1) to 4.70+/-0.12 mg mL(-1) and 0 mg mL(-1) to 3.42+/-0.11 mg mL(-1) in the case of teniposide.
Mass production of rubusoside using a novel stevioside-specific beta-glucosidase from Aspergillus aculeatus.[Pubmed:22530920]
J Agric Food Chem. 2012 Jun 20;60(24):6210-6.
Rubusoside (R) is a natural sweetener and a solubilizing agent with antiangiogenic and antiallergic properties. However, currently, its production is quite expensive, and therefore, we have investigated nine commercially available glycosidases to optimize an economically viable R-production method. A stevioside (ST)-specific beta-glucosidase (SSGase) was selected and purified 7-fold from Aspergillus aculeatus Viscozyme L by a two-step column chromatography procedure. The 79 kDa protein was stable from pH 3.0 to pH 7.0 at 50-60 degrees C. Hydrolysis of ST by SSGase produced R and steviol monoglucosyl ester as determined by (1)H and (13)C nuclear magnetic resonance (NMR). Importantly, SSGase showed higher activity toward ST than other beta-linked glucobioses. The optimal conditions for R production were 280 mM ST and 16.6 muL of SSGase at pH 5.1 and 63 degrees C. This is the first discussion detailing the production of R by enzymatic hydrolysis of ST and is useful for the food additive and pharmaceutical industries.
