Biological Activity

Description

Cynarin is an antichoke agent with a variety of biological activities including antioxidant, antihistamic and antiviral activities.

Cellular Effect

Cell Line	Type	Value	Description	References
MT2	ED₅₀	4 μM Compound: 1,5-DCQA	Concentration that inhibits Human Immunodeficiency Virus Type 1 (HIV-1)-induced death of MT-2 cells Concentration that inhibits Human Immunodeficiency Virus Type 1 (HIV-1)-induced death of MT-2 cells	[PMID: 9986720]

In Vitro

Cynarin inhibits taste receptors, making water to be sweet. It has been shown to have some pharmacological properties including hypocholesterolemic, hepatoprotective, antiviral, antibacterial, and antihistamic effects. Cynarin has marked antioxidant, anticholinergic, reducing ability, radical-scavenging, and metal-binding activities. Cynarin demonstrates 87.72% inhibition of linoleic acid lipid peroxidation at 30 mg/mL concentration. Cynarin exhibits effective DMPD⁺, ABTS⁺, O₂^-, DPPH¹, and H₂O₂ scavenging effects, reducing capabilities and Fe²⁺ chelating effects. IC₅₀ and K_i of cynarin for acetylcholinesterase enzyme inhibition are 243.67nM and 39.34±13.88 nM, respectively^[1]. Cynarin is a potential immunosuppressant that blocks the interaction between the CD28 of T-cell receptor and CD80 of antigen presenting cells. Cynarin blocks about 87% of the CD28-dependent "signal 2" pathway of T-cell activation under the condition of one to one ratio of T-cell and B-cell. Cynarin binds to the "G-pocket" of CD28 and thus interrupts the site of interaction between CD28 and CD80^[2].

Protocol

Cell Assay^[2]

The cytotoxicity of cynarin treatment of T-cells is measured by MTT colorimetric assay. 100 μL Jurkat cells are incubated with cynarin (0-1000 μg/mL) for 24 h at 37°C. The cell solution is then centrifuged and the supernatant removed. 200 μL of MTT is added and the cell solution is incubated again for 4 h at 37°C. 200 μL of DMSO lysis buffer is added into the cell medium and the concentration of dissolved MTT crystals is measured by plate reader at 560 nm^[2].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
