Принадлежит: GWANGJU INSTITUTE OF SCIENCE AND TECHNOLOGY

The present invention relates to a porous polyurea material and a method for preparing the same. The porous polyurea material may be prepared by polymerization and crosslinking of tetra(4-aminophenyl)methane with a monomer two to four isocyanate (—NCO) groups. The method includes: mixing an organic solution of tetra(4-aminophenyl)methane with an organic solution of a monomer having two to four isocyanate groups; reacting the mixed solution under a nitrogen atmosphere; and drying a semi-solid or solid material formed by gelation of the reaction solution, or adding the reaction solution to a non-solvent before gelation of the reaction solution to form a precipitate, followed by drying, or applying the reaction solution to a substrate before gelation of the reaction solution, followed by drying. According to the present invention, the introduction of the monomer having a tetrahedral structure can impart good chemical resistance, heat resistance and durability to the porous polyurea material.

A method of cancer intervention or eradication by administering an effective amount of an endogenous ligand for the aryl hydrocarbon (Ah) receptor (AhR) named ITE or one of its analogs (the active ingredient) to a subject with cancer is disclosed. An effective dose and dosing frequency of the active ingredient are determined by measuring its blood levels of the subject after dosing. The active ingredient formulated with a carrier system is applied topically, enterally, or parenterally to the subject. The formulated drug can also be administered together with one or more of other cancer therapeutic agents. A maintenance dosing is provided after the subject is free of cancer to insure the cancer eradication. Subjects with cancers of prostate, liver, lung, ovarian, and breast are preferably accepted for treatment.
