These characteristic MAP キナーゼ 阻害剤 properties make emulsomes to promising candidates for poorly water soluble thera peutic agents such as curcumin. As recently demonstrated, the assembly of phospho lipids and triglycerides to form a stable dispersed emul somes can be prepared by a dehydration rehydration process followed by temperature controlled extrusion, In the present study, curcumin emulsome nanofor mulations, or so called CurcuEmulsomes, were formu lated using the same methodology, and characterized with respect to their structural and biophysical proper ties. HepG2 cell line was used as the in vitro cellular model to study cellular uptake of CurcuEmulsomes and to evaluate the biological effects of the incorporated cur cumin on cellular morphology, as well as viability, com pared to its free form.<br><br> Cell cycle studies were performed to study CurcuEmulsomes effect on cell proliferation and implicitly to verify the incident of prolonged release of curcumin in biological level. Results CurcuEmulsome nanoformulation The structural design of CurcuEmulsomes buy MK-1775 enables cur cumin to be localized in the inner solid tripalmitin core, as well as inside the phospholipid layers surrounding and stabilizing the nanocarrier, In contrast to free curcumin, poorly soluble in water, cur cumin incorporated into CurcuEmulsomes is a colloidal solution, Forming an intensive turbid sus pension, CurcuEmulsomes achieved curcumin concen trations up to 0.<br><br> 11 mg ml as estimated by absorbance measurements, where the latter value corresponds to a 10,000 fold increase in solubility purchase MS-275 of curcumin, The aforementioned values correspond to the concen trations of curcumin incorporated into CurcuEmul somes, as unincorporated curcumin in the solution was already spin down after a centrifugation process. Spin down resulted in recovery of incorporated curcumin corresponding to 90% of total within the supernatant containing CurcuEmulsomes, indicating that a stable in corporation was achieved. Particular characterization of CurcuEmulsomes TEM micrographs verified that CurcuEmulsomes are spherical in shape, and hence, similar in size and morph ology to empty emulsomes, DLS analysis with Zetasizer Nano ZS determined the average diameter of ten distinct CurcuE mulsome formulations as 286 27 nm where the plus minus sign indicates the margin of aver age size of numerous CurcuEmulsome formulations made of the same composition.<br><br> Consistent with this value, the mean diameter of empty emulsomes was pre viously reported to be 297 28 nm, In addition, zeta potential of CurcuEmulsomes is comparable to that of empty emulsomes, With the aid of the auto fluorescence properties of curcu min, it was possible to evidence the incorporation of curcumin into emulsomes and that the prepared nano carrier system is a stable dispersed formulation in water, Consequently, the presented data declines any significant influence of incorporated drug neither on the size nor on the surface potential of the nanocarrier, which could further affect the particular dispersity of the nanocarrier in water. Tautomeric curcumin incorporated into CurcuEmulsomes in its enol form Curcumin is a yellow colored tautomeric compound that, upon dissolution in an organic solvent, absorbs light in the visible wavelength range, In nonpolar, i.
