Hydrophilic drugs are typically encapsulated within the aqueous interior of large unilamellar vesicles [16] whereas hydrophobic drugs are embedded into the phospholipid layers of multilamellar type vesicles to maximize the drug loading concentration [17], [18]?and?[19]. Therefore, for hydrophilic drugs, the increase in the volume of aqueous interior may be advantageous to get the enhanced drug loading concentration, whereas for hydrophobic drugs, the increase in the number of phospholipid layers may do. In addition to, either widening the space between phospholipid molecules or between layers may provide more spaces to load the hydrophobic drugs in liposomes. In an attempt to investigate a possibility to develop liposomes containing both of anticancer agent and TB as a?more [http://www.selleckchem.com/products/MLN-2238.html selleck screening library] effective anticancer drug carrier, we sought to examine whether the incorporation of small amount ([http://www.selleckchem.com/products/gsk-j4-hcl.html selleck chemicals] Korea), respectively. Each medium was supplemented with 10% heat inactivated fetal bovine serum (Hyclone, Logan, UT, USA) and 100?units/mL Penicillin/streptomycin. Cells were grown in incubators in a humid atmosphere of 95% air and 5% CO2. TB and Tween 80 were purchased from Sigma�CAldrich Inc (St.?Louis, MO, USA). Celecoxib was obtained from LKT Laboratories (Minneapolis, MN, USA). 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC) was purchased from Avanti Polar Lipids (Alabaster, AL, USA). All other chemicals were of reagent grade and used without further purification. [http://en.wikipedia.org/wiki/Ribosomal_s6_kinase S6 Kinase] Liposomes with or without TB were prepared with a slight modification from that described in our earlier study [7]. Briefly, 1?mg celecoxib and 24?mg DMPC with or without TB were first dissolved in t-butyl alcohol. After rapid freezing at ?70?��C, mixtures were subjected to freeze-drying (EYELA FDU-1200, Japan). After overnight freeze-drying, the mixture was suspended in 1?ml of 100?mM phosphate-buffered saline (PBS, pH 7.4) to produce a multilamellar type liposomes. Liposomes were briefly vortexed and sonicated in a bath type sonicator for an hour at 37?��C to produce small multilamellar vesicles. To remove the unentrapped/precipitated celecoxib from celecoxib-incorporated liposomes, the liposome dispersions were immediately filtered through a 0.8?��m membrane filter. The prepared liposomes were stored at 4?��C until use.
