V. PBS was added to the resulting pellet and redispersed. As a result of measuring the particle size by the method of Reference Example 7, the average particle size was 166 nm.
- Figure 2 shows the structure of the amphiphilic compound (VIII).
- a particle formulation was prepared using amphiphilic compounds (X), (XI), (XII), and (i).
- Example 21 MRI contrast effect by PLGA matrix particles containing amphiphilic compound (VIII) encapsulating magnetite
- MRI imaging was performed (Toshiba, Visartl. 5 Tesla).
- a metastatic liver cancer model mouse BALBZc, male
- the mouse was imaged before administration of magnetite particles to obtain a T2-weighted image.
- a magnetite particle solution (dose: 0.45 mg / kg as iron amount) suspended in physiological saline was also administered once by mouse tail vein force, and MRI imaging was performed 5 minutes after administration.
- Example 22 MRI contrast effect by PLGA matrix particles containing amphiphilic compound ( ⁇ ) encapsulating magnetite as a constituent element
- MRI imaging was performed (Visartl. 5 Tesla, manufactured by Toshiba). La HWistar, o 71 ) was used as the imaging target.
- the mouse was imaged before administration of the magnetite particles to obtain a T2-weighted image.
- a magnetite particle solution (dose: 0.45 mg / kg as iron amount) suspended in physiological saline was administered as a single dose from rat tail vein force, and MRI imaging was performed 30 minutes after administration.
- a decrease in MR signal in the liver region was clearly observed before and after administration, indicating a contrast enhancement effect in the liver.
- the signal intensity of the liver and muscle parts was measured from the obtained images, and the signal intensity ratio between organs calculated by the following formula was compared before and after administration. A significant signal strength ratio decrease of about 40% was observed.
- the pharmaceutical preparation of the present invention has no protein adsorptive property, it can be trapped in the reticuloendothelial system and can form a particulate pharmaceutical preparation with good retention in blood.
- the pharmaceutical preparation of the present invention is used for delivery of various drugs, sustained pharmacological effects can be expected.
- the pharmaceutical preparation of the present invention is an easily synthesized and biodegradable amphiphilic compound that does not have a branched chain or the like, and can be used for a saccharide or the like on the particle surface if a ligand is selected according to the purpose of delivery. Since it is possible to form Gand's cluster, it is possible to form a particle preparation that exhibits remarkable site orientation. Therefore, it is possible to selectively deliver a drug only to a specific organ or diseased site, and when compared with systemic administration, the drug efficacy increases with the increase in drug delivery amount at the target site or the same effect. It is possible to reduce the total amount of drugs administered and to reduce the side effects.
- the pharmaceutical preparation of the present invention enables the preparation of particles having a high drug-retaining ability for various drugs by selecting the matrix-forming material, and the biodegradability and solubility of the matrix-forming material.
- the drug release characteristics can be controlled by selecting.
- the pharmaceutical preparation of the present invention enables site-specific MRI imaging when a diagnostic agent such as an MRI contrast component is used as a drug, and has higher resolution and higher accuracy than conventional contrast agents. This makes it possible to diagnose the disease site.
