Usage

Uses

Used in Pharmaceutical Industry:
D-tetrahydropalmatine is used as a therapeutic agent for its potential in treating substance abuse, depression, and anxiety disorders. It is valued for its ability to modulate neurotransmitter levels, particularly dopamine and serotonin, which may contribute to its neuroprotective and antidepressant effects.
Used in Traditional Chinese Medicine:
D-tetrahydropalmatine is used as a component in various traditional Chinese medicine formulations for its mild sedative, anxiolytic, and analgesic properties. Its long history of use in traditional medicine suggests a broad range of applications for managing stress, pain, and promoting overall well-being.
Used in Neuroprotective Applications:
D-tetrahydropalmatine is used as a neuroprotective agent due to its potential to modulate neurotransmitter levels in the brain, which may help in protecting neurons from damage and degeneration, thus contributing to its potential use in treating neurological disorders.
Used in Research and Development:
D-tetrahydropalmatine is used as a subject of research for further exploration of its mechanisms and potential therapeutic applications. Its investigation in modulating neurotransmitter levels and its effects on mental health conditions highlight its importance in the development of new treatments for various disorders.

COMPOUNDS, COMPOSITIONS AND METHODS FOR TREATING NASH, NAFLD, AND OBESITY

The present technology relates to methods of treating NASH, NAFLD and/or obesity using compounds of Formulas I, II, III, IV, V, and/or VI. The methods include administering to a subject suffering from one or more of non-alcoholic steatohepatitis (NASH), non- alcoholic fatty liver disease (NAFLD) and/or obesity a therapeutically effective amount of such a compound

Bioactive isoquinoline alkaloids from Corydalis saxicola

Twelve isoquinoline alkaloids including two new nitro-containing tetrahydroprotoberberines, (-)-2,9-dihydroxyl-3,11-dimethoxy-1,10- dinitrotetrahydroprotoberberine (1) and (+)-4-nitroisoapocavidine (2), were isolated from the whole plant of Corydalis saxicola Bunting. The structures of the new compounds were established by spectroscopic analysis and chemical evidence. The inhibitory activity of these isolates against cholinesterase and canine parvovirus were evaluated. Compounds 1 and 1a, (+)-1-nitroapocavidine (5), berberine (8), palmatine (9), dehydrocavidine (10), and sanguinarine (11) showed potent inhibitory activity against acetylcholinesterase with IC 50 values of less than 10M, while only compound 1 possessed weak activity against canine parvovirus. Structure-activity studies demonstrated that the nitro substituents at ring A in the tetrahydroprotoberberines led to an increase in the anti-acetylcholinesterase activity.

Compounds disclosed herein also increase HDL-C, lower total cholesterol, LDL-cholesterol, and triglycerides and increase hepatic LDL receptor expression, inhibit PCSK9 expression, and activate AMP-activated protein kinase.

CORYDALINE DERIVATIVES USEFUL FOR REDUCING LIPID LEVELS

The present technology relates to compounds of Formulas (V) and (VI) and methods of making and using such compounds. Methods of use include prevention and treatment of hyperlipidemia, hypercholesterolemia, hypertriglyceridemia, hepatic steatosis, and metabolic syndrome. Compounds disclosed herein also lower total cholesterol, LDL- cholesterol, and triglycerides and increase hepatic LDL receptor expression, inhibit PCSK9 expression, and activate AMP-activated potein kinase.

COMPOUNDS, COMPOSITIONS AND METHODS FOR REDUCING LIPID LEVELS

Compositions comprising extracts or isolated or purified compounds from plants of the genus Corydalis provide prevention and treatment of hyperlipidemia, hypercholesterolemia, hypertriglyceridemia, hepatic steatosis, and metabolic syndrome. Corydalis compounds and their derivatives of natural and synthetic origins lower total cholesterol, LDL-cholesterol, and triglycerides and increase hepatic LDL receptor expression and activate AMP-activated protein kinase. Specific stereoisomers of Corydalis compounds with lipid lowering activity include 14R-(+)-corypalmine, 14R,13S-(+)-corydaline, 14R-(+)-tetrahydropalmatin, (+)-corlumidin, d-(+)-bicuculline, and (+)-egenine.
