摘要:
An apparatus for forming ultrafine particles, including: a light source generating a laser beam to be irradiated at an organic substance; at least one microflow channel capable of passing therethrough a suspension containing the organic substance; and a flow device for allowing the suspension containing the organic substance to continuously or intermittently pass through the microflow channel, the organic substance present in the microflow channel being irradiated with the laser beam at least once within a predetermined period, thereby forming ultrafine particles of the organic substance.
摘要:
A method of producing a medicinal nanoparticle suspension is provided, wherein a medicinal ingredient added in a suspending solution is ground to form nanoparticles of the medicinal ingredient by irradiating the suspending solution with a laser. The process is implemented after adding a poorly water-soluble or water-insoluble medicinal ingredient of a drug in a poor solvent to form the suspending solution.

摘要:
A method of producing water-insoluble anti-cancer drug in the form of particulates, the method including preparing a water-insoluble anti-cancer drug having at least one multiple bond in the structure, and irradiating said water-insoluble anti-cancer drug with a laser beam having a wavelength of a low absorption portion in the vicinity of the foot of an absorption curve on the long wavelength side within the absorption band until said water-insoluble anti-cancer drug is formed into particulates having an average particle diameter of 50 to 200 nm.
摘要:
A water-insoluble medicine in the form of particulates, having an average particle diameter of 50 to 200 nm; and a particulate complex of the water-insoluble medicine and a polymer electrolyte, having an average particle diameter of 50 to 250 nm.

摘要:
An apparatus for coating particles with a polymer electrolyte, which includes at least one polymer membrane shell-coating part, the particles being coated with a membrane shell in the at least one polymer membrane shell-coating part by performing a step including contacting the particles having a predetermined charge with the polymer electrolyte having a charge opposite to that of the outer surface of the particles, thereby forming a membrane shell on the surface of the outermost layer of the particles.
摘要:
Preventive or therapeutic agents for pancreatic cancer, ovarian cancer, or liver cancer of the present invention comprise a water-soluble prodrug represented by formula 1 described below, or a pharmaceutically acceptable salt, or a hydrate or solvate of the prodrug or pharmaceutically acceptable salt, (wherein, R1 represents a hydrogen atom, or a C1-C6 alkyl group; W represents a divalent group comprising a tertiary amino group or a divalent group comprising a sulfonyl group, and Y represents a residue of a compound represented by Y—OH comprising an alcoholic hydroxyl group, wherein said Y—OH is a camptothecin, a taxane, or an anticancer nucleotide).
