5 results about "OPIOID TOLERANCE" patented technology

Problem The purpose of the present invention is to provide a novel method for prevention and / or treatment of opioid tolerance or opioid dependence. Specifically, the purpose of the present invention is to develop peptide-based blockers to block MOR-DOR and KOR-DOR heterodimerization. In addition, the purpose of the present invention is to develop homodimer blockers for MOR, DOR, and KOR which modulate their downstream signaling without affecting their internalization. Solution The present invention is a prophylactic and / or therapeutic agent for the prevention and / or treatment of opioid tolerance or opioid dependence comprising the peptide which inhibits the dimer formation of the opioid receptor, wherein the above opioid receptor dimer is a heterodimer or a homodimer formed from one or two opioid receptors selected from the group consisting of the μ type (MOR), the κ type (KOR), and the δ type (DOR).

The application discloses application of a peripheral nervous system Mas-related G protein-coupled receptor D as a target point in preparation of a medicine for screening for relieving opioid tolerance. Jun The application further provides a medicine composition for regulating opioid tolerance, containing a Mas-related G protein-coupled receptor D siRNA sequence shown in SEQ ID NO. 1 or a siRNA sequence shown in SEQ ID NO. 2. The application further provides an in-situ hybridization kit for detecting expression of a Mas-related G protein-coupled receptor D gene in a dorsal root ganglion tissue of a peripheral nervous system. The application expands a new path for opioid companion diagnosis and intervention.

The invention discloses application of a peripheral nervous system Mas related G protein coupled receptor D as a target spot in preparing and screening a medicine for relieving opioid medicine tolerance. The invention also provides a pharmaceutical composition for regulating and controlling the tolerance of the opioid drugs. The pharmaceutical composition contains a Mas related G protein coupled receptor D siRNA sequence as shown in SEQ ID NO. 1 or a Jun siRNA sequence as shown in SEQ ID NO. 2. The invention also provides an in-situ hybridization kit for detecting the expression of the Mas related G protein coupled receptor D gene in the dorsal root ganglion tissue of the peripheral nervous system. According to the invention, a new path for accompanying diagnosis and intervention of opioid drugs is expanded.
