Title:
COORDINATION POLYMER NANO MATERIAL HAVING COMBINED PHOTODYNAMIC-STARVATION THERAPY FUNCTION, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/130514
Kind Code:
A1
Abstract:
A coordination polymer nano material having a combined photodynamic-starvation therapy function, a preparation method therefor and an application thereof. The coordination polymer nano material comprises a carrier and an enzyme. The enzyme is loaded in the carrier. The enzyme is glucose oxidase (GOx) or a mimic enzyme having a GOx-like activity. The carrier is a 1,2,4-triazole copper (I) complex. The GOx in the coordination polymer nano material can be specifically released in a tumor cell, and catalyze the oxidation of glucose in the tumor cell, consuming glucose and oxygen in the tumor cell, and improving the levels of acidity, low oxygen and hydrogen peroxide, thereby blocking the energy supply to the tumor cell, and achieving a starvation therapy. Meanwhile, hydrogen peroxide produced by the starvation therapy can also be used as a raw material for a photodynamic reaction of the 1,2,4-triazole copper (I) complex, thereby enhancing the type I photodynamic therapy effect, and finally achieving an efficient combined photodynamic-starvation therapy.
