Abstract
There is provided a drug delivery composition containing an acid-resistant cell that encloses a drug in the cell. In addition, there is provided an acid-resistant cell in which a drug is enclosed in the cell, where the drug is localized in the sac-shaped membrane structure included in the acid-resistant.
Claims18
A drug delivery composition comprising an acid-resistant cell that encloses a drug,
- wherein the acid-resistant cell is a cell in which cell rupture is caused at pH 7, and the acid-resistant cell is a haploid cell of algae that belong to the class Cyanidiophyceae.
An acid-resistant cell that encloses a drug in the cell,
- wherein the acid-resistant cell is a cell in which cell rupture is caused at pH 7, and the acid-resistant cell is a haploid cell of algae that belong to the class Cyanidiophyceae.
An acid-resistant cell that encloses a drug in the cell,
- wherein the drug is localized in a sac-shaped membrane structure included in the acid-resistant cell, and
- the acid-resistant cell is a cell in which cell rupture is caused at pH 7, and the acid-resistant cell is a haploid cell of algae that belong to the class Cyanidiophyceae.
A drug carrier comprising an acid-resistant cell,
- wherein the acid-resistant cell is a cell in which cell rupture is caused at pH 7, and the acid-resistant cell is a haploid cell of algae that belong to the class Cyanidiophyceae.
An acid-resistant cell comprising an exogenous substance,
- wherein the acid-resistant cell is a cell in which cell rupture is caused at pH 7, and the acid-resistant cell is a haploid cell of algae that belong to the class Cyanidiophyceae.
