Abstract:
Disclosed herein are cationic polymer nanocapsules encapsulating an oil-soluble active ingredient, and a cosmetic composition containing the same. The cationic polymer nanocapsules have a molecular weight of 5,000-100,000, a surface potential of 5-100 mV and a particle size of 50-500 nm. Also, disclosed is a cosmetic composition containing said cationic polymer nanocapsules.
Abstract:
Provided is an anticancer prodrug sensitive to a target protease. The anticancer prodrug includes an anticancer drug, peptide that is specifically decomposed by the target protease excessively secreted by cancer cells, and a polymer that is specifically accumulated at a target cancer site. When the inactive anticancer prodrug is administered, the anticancer prodrug is accumulated at the target caner site and then the peptide is decomposed by irradiation of radioactive rays, thereby releasing an active anticancer drug at the target caner site. Accordingly, destruction of normal cells can be minimized and a high anticancer therapeutic effect can be obtained by using a small amount of the anticancer drug administered and a small amount of radioactive rays irradiated.
Abstract:
The present invention relates to an anticancer prodrug consisting of peptide of acetyl-SEQ ID NO: 1-linker-anticancer drug. The anticancer prodrug effectively provides an anticancer drug unstable in acid or base, such as doxorubicin, in a form of prodrug. Thus, the anticancer prodrug exists as a non-toxic inactive form when administered into the body, but effectively releases the anticancer drug as an active ingredient in the target area in the presence of caspase activated by radiation or UV treatment after administered into the body. Accordingly, the anticancer drug exhibits selective anticancer effects on cancer cells, thereby maximizing the therapeutic effect and minimizing the side-effects of chemotherapy.
