Abstract

Danhong injection (DHI) is a traditional Chinese medicine injection that has been widely used in therapy for cardiovascular diseases. However, neither its mechanism nor its active constituents are clearly understood. Our research aimed at identifying the anti-inflammatory ingredients and mechanism of DHI by combining high-throughput screening (HTS) with network pharmacology analysis. The human endothelial cell line EAhy926 was cultured in vitro. Methyl thiazolyltetrazolium (MTT) and lactate dehydrogenase (LDH) assays were performed to detect cell viability. The expression of Bcl-2 and Bax, interleukin-6 (IL-6), inhibitor of nuclear factor kappa-B kinase (IKK), phosphorylated IKK, phosphorylated NF-κB and phosphorylated IκB-α from the supernatant were determined. Then, we constructed an assay system combining ultra-performance liquid chromatography/quadrupole time-of-flight mass spectrometry (UPLC/Q-TOF-MS) with an NF-κB activity luciferase reporter to screen DHI for essential anti-inflammatory components, and the results were verified using network pharmacology. DHI could significantly suppress inflammatory responses, and the mechanism may be via an NF-κB-dependent pathway. We found nine potential anti-inflammatory ingredients:...Continue Reading

Anti-inflammatory Treatments

A drug or substance that reduces inflammation (redness, swelling, and pain) in the body. Anti-inflammatory agents block certain substances in the body that cause inflammation and swelling. Discover the latest research on anti-inflammatory treatments here

BCL-2 Family Proteins

BLC-2 family proteins are a group that share the same homologous BH domain. They play many different roles including pro-survival signals, mitochondria-mediated apoptosis and removal or damaged cells. They are often regulated by phosphorylation, affecting their catalytic activity. Here is the latest research on BCL-2 family proteins.
