Solu-Resveratrol (Solu-RSV)
Sub-mircornized Trans-Resveratrol based on SolumerTM technology
Solu-RSV: SolumerTM- Resveratrol Resveratrol (RSV), a polyphenol, naturally present in several
plants such as grapes, was shown to prolong longevity. It’s a small molecule activating the SIRT1 protein, responsible for cell protection against age-related disorders.
The Need: Why the SolumerTM Resveratrol is needed?
Resveratrol is practically insoluble in aqueous media. It demonstrates very low bioavailability and rapid, extensive metabolism, resulting in only trace amounts of unchanged resveratrol in the systemic circulation (Walle, et. al; High absorption but very low
bioavailability of oral resveratrol in humans; Drug metabolism and disposition; 2004; Vol. 32, No. 12; 1377–1382).
Solubest’s Solution:
To answer this need Solubest has developed highly bio-available formulation of resveratrol utilizing Solumer™ proprietary, patent protected technology.
Recent Scientific Evidences: RSV can Influence the Longevity Path through Multiple Mechanisms:
• RSV reduced both gene expression and release of pro-inflammatory cytokines. (The Journals of Gerontology, 2012)
• The beneficial health effects of RSV are mainly mediated by the expression and regulation of deacetylase Sirt1, a protein associated with aging. Recent research in MIT/ Harvard reinforces the claim that resveratrol interacts with key genes in mitochondria. MIT researchers have shown that the mice with normal SIRT1 function given RSV showed dramatic increases in energy (Cell Metabolism, May- 2012) http://hms.harvard.edu/content/more-evidence-longevity-pathway
• Recently, (Feb. 2, 2012) NIH researchers have presented evidence that RSV could exert its function via Sirt1-independent mechanisms: RSV l inhibits certain types of phosphodiesterases, enzymes that help regulate cell energy. Up-regulation of Adiponectin by RSV is also regulated by both the Akt/FOXO1 and the AMP-activated protein kinase signaling pathways and DsbA-L. RSV has a stimulatory effect on the expression levels or the secretion of adiponectin, an adipocyte-derived hormone that plays an important role in the regulation of insulin sensitivity and energy homeostasis, including decomposition of blood sugar and lipid. http://www.jbc.org/content/287/14/11566.abstract?sid=1364a455-e90b-4491-9636-7b953d5fd105
• Significant RSV-induced cardioprotection against ischemia/reperfusion (IR ) injury was determined by recovery to basal level of specific group of microRNA expressions in heart that have altered during IR injuries http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3009730/

Anti-aging: proposed protective models of action of RSV in aging-associated processes
RSV effects on intracellular signaling associated with prevention of EC activation and unstable plaque development. (Source: Vasc Cell. 2012; 4: 9)
The model predicts that resveratrol, via up-regulating Nrf2-driven antioxidant enzymes and eNOS, down-regulating TNFα-activated NADPH oxidases, exerting mitochondrial protective effects and inhibiting NF-κB, significantly attenuates vascular oxidative stress and inflammation in aging . (Source: Ann N Y Acad Sci.; 2012).
Model of RSV mitichondrial protection:, by activating SIRT1 and/or AMPK, up-regulates Nrf2-driven antioxidant enzymes and eNOS, and down-regulates TNFα-activated NADPH oxidases; by reducing oxidative stress RSV increases the bioavailability of nitric oxide (NO), promoting activation of PGC1α, which increase mitochondrial biogenesis (Source: Exerc Sport Sci Rev. 2011 July; 39(3): 128–132.).
Solumer™: Essential technology characteristics for optimal bio-potency formulation of Solu-RSV
Improved Solubility
Improved Bioavailability
Improved Efficacy
Bottom-up particle assembly
during spray-drying process
Instant powder: upon dispersion in
aqueous media forms nano-colloids
Depressed melting temperature and enthalpy of API
Improved dissolution and solubility in bio-relevant media
Less ordered-crystalline lattice
Submicron particles of API are
homogeneously dispersed in
polymer matrix
SolumerTM is composed of porous micro-
aggregates
Distinct thermodynamic pattern:
favorable for dissolution
Raw resveratrol melting
Formulated Resveratrol melting
• Formulated RSV demonstrates significant reduction in melting temperature and enthalpy in comparison with raw crystalline material.
• Such high energy state requires less energy for dissolution!
Upon contact with water or biological fluids Solumer™ powder is self-dispersed to form uniform nano-colloids with mean particle size in a range of 0.5-5 µm. The colloidal particle is not entire monolith; it is built from subunits of 50-100 nm.
SEM images demonstrates that Solu-RSV is constructed from the porous polymer aggregates (100-200 mm) covered by submicron-micron particles of resveratrol (0.5-5 mm);
Nano- and sub-micron particles of active compound are embedded in polymer matrix
Altered, less ordered-crystalline lattice of stabilized Solu-RSV vs. raw RSV- a distinct feature

Formulated API possesses a high energy crystalline structure, stabilized by interaction with polymers. Such disordered structure reduces the dissolution energy barrier, inherent in the typical rigid crystal of poorly soluble actives!
Instant Powder -upon dispersion in aqueous media forms nano-colloids
Solu-RSV Instant Powder characteristics: • Flowability – easy handling and
processing
• Compressability – allows multiple dosage forms
• Stability – long shelf life
• Bulk instant powder is easy to disperse in liquid
