Description of the invention: [Technical field to which the invention belongs] The application of the jiili case is based on the US provisional application 61/055, 784, and the application is the benefit of May 23, 2008. This is incorporated herein by reference in its entirety. Technical Summary The present invention broadly focuses on drug delivery, and more particularly on transdermal drug delivery. [Prior Art] By-Drug Delivery (TDD) can provide several advantages over injections and (10) delivery, etc. When compared to oral delivery, gastrointestinal drug metabolism, reduced efflux (fct teffet), and sustained release of the drug are provided for up to seven days. When she is handsome, she can avoid the necessary pain and infection. In theory, _ _ _ _ _ may be beneficial in the delivery of many therapeutic eggs, _ protein f gastrointestinal decomposition and poor gastrointestinal absorption. Such as interference with eggs from fine blood clearance, and in order to make it blood The degree is maintained at a high value, and needs to be delivered at a sustained rate. The U.S. patent case number and the transdermal device are easy to shoot on the (4). 5,814,599) 〇In spite of these advantages, the skin is sealed by a skin. It has low penetrability and is currently only very rare in clinical applications and there are no proteins or peptides to be administered in the form of percutaneous 4 201103574. This low permeability is due to the stratum corneum (sc) (which is The outermost layer of the skin, caused by the flat, dead cells (keratinocytes) filled with keratinous fibers of the lipid bilayer membrane. The height-regular arrangement of the lipid bilayers provides sc-impermeable properties (US Patent No. 5,814,599). Good method. [Summary of the Invention] Transdermal drug delivery provides an advantageous method of administration instead of sputum delivery and injection. However, the skin substance can be worn by the phase #low, so its application is limited to Drugs. Therefore, there is still a need to propose a solution to the aforementioned shortcomings and inadequacies in the art, especially in combination with a method for improving transdermal drugs.

Preparation of liposomes by membrane hydration. Briefly, lipids Compound DSPC, acryl PE and cholesterol were mixed in a gas mixture at a molar ratio of ι 〇: 〇ι: 〇.7, and the solvent was removed by rotary evaporation to form a lipid film on a round bottom flask. The lipid film is then dried under vacuum overnight to remove the organic solvent. One milliliter of (10)-glucose is added to hydrate the 2 〇 〇 f f film, and the purpose (4) floats to hold the next one. After using the singularity, the squirting of the lipids and the floating liquids for 1G minutes. The granules of the liposomes were obtained by pushing the slabs (10), 20 times by pushing (10). path. Any unblocked, glucosamine was removed from the liposomes by gel filtration by 'sephadex G_25 column (10) reading Biosciences AB). Example 2. Preparation of a drug carrier with additional proteolytic enzymes Papain conjugated to the surface of a liposome 201103574 by using a coupling agent 1-ethyl-3-[3-dimethylaminopropyl]carbonyl Amidoxime (EDC 'Sigma) (0.2 M), and a total of one amino group of papain compound (1 mg) and a carboxyl group of liposome (2χ122 liposome/ml) Yoke effect. The coupling reaction 110 was carried out in phosphate buffered saline for 2 hours at room temperature. The papain-added lipid system is purified by HPLC (inter-performance liquid chromatography) using a size exclusion chromatography column (Bi〇SepSEC_S2〇〇〇, Fenomenis) to remove unreacted papaya Protease. Fig. 1 is a schematic diagram showing that the papain molecule 1〇4 and the county 1〇6 located on the lipid double layer surface 108 of the liposome are coupled with a difficult EDC coupling reaction. EDC is a carboxyl group and an amine-reactive zero-length crosslinker. The coffee head first reacts with the silk 106 and forms an amine-reactive 〇-mercaptoisourea-interstrate which rapidly reacts with the amine group to form a guanamine bond. EDC is here used to link the amino group of papain 104 to a carboxyl group (10) located on the surface of the liposome. Papain 1 is considered to be a permeability enhancer for increasing the specific drug molecule 1〇2 through the pores of the skin 2 (Fig. The papain class itself is too large to pass the live epidermis. 'However Issues such as its instability and safe concentration have been proposed. Figure 2B illustrates the use of micronized or nanochemical drug carriers (eg, liposomes) to concentrate the bioactive molecule 1〇2 in the carrier, and The papain 104 on its surface is used to enhance and extend the transport of bioactive molecules through the pores 2G6 of the skin 2(10).

Guanhe threatened to take the material 5 guagua protein or = papain liposome leaching (9) plus people (Papain Concentrate The range is from 0.25 mg/m to 2 tons (10)' and it is continued under the pit for centrifugation. The reaction is terminated by adding 15 of 3 N hydrochloric acid. The sample absorbance is recorded under the sample. The egg self-enzyme concentration is matched with the standard curve of free-form papain. In order to avoid the interference of liposome, all the samples are dissolved and the absorbance is measured; first, the αΐμπι filter (Milipo (trans-p〇re) transition). Hunting is a quantitative method for measuring the total papain concentration in each of the papain-containing liposome knowledge tubes. The total number of papain molecules on a single liposome is determined by the total number of papain molecules (N papain). Divided by the total number of liposomes (N_)' to calculate the number of papain molecules on a single liposome (I): N papain / N lipid theory term N papaya egg (four) means measured by color rendering The total number of papain molecules. The term N _ indicates the total number of liposomes by dividing the total number of disc lipid molecules 12 201103574 by the number of lipid-filled molecules present in a single, 200 nm liposome (approximately 16 x lO5 phospholipids) Calculated by molecular/liposome. The concentration of phospholipids was measured by the colorimetric method as follows: 27.03 g of iron hexahydrate hexahydrate (FeCl36H2〇) and 30.4 g of thiocyanate (nhjcn) were dissolved.丨L deionized water to prepare a stock solution of ammonium iron thiocyanate. Prepare a standard calibration curve for phospholipid concentration. Mix the individual phospholipid samples with an equal volume of salt solution for one minute. Phase separation, and record the absorbance value in UV/Vis to match the phospholipid concentration of the sample. Calculate the effective papain concentration per single conjugated liposome for each enzyme-conjugated liposome, the corresponding effective enzyme The concentration was calculated as follows: Calculate the total surface area of the mono-liposome (A = 4AR2). Assuming that papain is self-distributed on the lipid surface, the distance between the two papaya eggs is equal to d =, / A, /2. Wherein "η" represents the number of papain per liposome and "Α" refers to the surface area of the plastid. A papain molecule occupies a volume of d. Calculate the effective papain concentration of the total number of molecules of papain per liter. As shown in the domain 3, the effective papain system of each of the Saskatchewan is directly proportional to the number of molecules of the papain attached. Taking the X-axis value of the 350 papain molecule/liposome as an example, the phase = effective papain concentration is 245 coffee. However, the concentration of protease in the test tube of the papa egg from the enzyme (4) was determined by papain. Therefore, the concentration of the effective wood terminase per phlegm is actually increased by a factor of (5) / U8 = guan), which is due to the fact that the papain molecule is concentrated on the surface of the liposome. Example 3: Transdermal delivery of encapsulated bioactive agents Transdermal penetration efficacy of drug carriers with additional proteolytic enzymes was assessed using an in vitro Franz diffusion chamber. Briefly, a piece of pig skin tissue with a thickness of up to 500 μm was cut into a 500 μm thick pig skin tissue using a motorized skinning knife (zimmer Inc., USA), placed between two halves of a vertical Franz diffusion chamber (R=丨5 mm, Skin area: 丨.77 cm2 'receiver volume: 12 ml) and fixed with a clip. Permeability was measured in a variety of different transdermal drug delivery modes. The following four different drug delivery modes were tested: (1) the addition of papain to the surface of the scorpion scorpion (350 papain molecule / 200 liposome, pure papain 26 , total glucose 5 ^; (2) Free state papain (5〇〇

Samples from each group (1 ml per sample) were added to the donor compartment. Fill the receiving compartment with 0.1 MPBS. Samples were taken every 30 minutes for 3 hours and analyzed by the glucose analysis kit (BioVisi〇n c〇) according to the manufacturer's instructions (tecan, Inifimtel VQOO). All experiments were done at room temperature. The total amount of papain calculated for each additional liposome is 〇.25 m_, which is equivalent to 350 papain molecules/liposomes, or equivalent to an effective papain concentration of 5.6 mg/m, which is reported to be papaya eggs (4). The safe concentration is about 039.039 mg/ml, which is equal to 4 μΜ (US005534260A) in solution. 14 201103574 Table 1*
