Velutin

Kundenbewertung

Based on 1 Customer Validation

Velutin is a flavonoid. Velutin can be extracted from mistletoe. Velutin inhibits mushroom Tyrosinase activity with an IC₅₀ of 910.1 μM. Velutin inhibits p38 phosphorylation, the NF-κB pathway and the MAPK pathway. Velutin prevents articular cartilage degeneration and subchondral bone loss. Velutin slows down the progression of intervertebral disc degeneration. Velutin exhibits inhibitory effects on melanogenesis, skin whitening, anti-inflammatory, anti-allergic, anti-oxidant and antibacterial activities. Velutin can be used in studies related to pigmented diseases, osteoarthritis and intervertebral disc degeneration.

In Vivo

Velutin (32 μM; intra-articular injection; once weekly for 8 consecutive weeks) exerts dual protective effects against articular cartilage degeneration and subchondral bone loss in DMM-induced osteoarthritis mice, reduces the OARSI score, increases the expression of aggrecan and type Ⅱ collagen, and inhibits the activation of p-p38 MAPK^[2].
Velutin (i.p.; once daily; for 4 consecutive weeks; 5-10 mg/kg) dose-dependently alleviates intervertebral disc degeneration in a mouse model of lumbar instability^[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

C57BL/6 (7-week-old male, DMM-induced osteoarthritis)^[2]
Dosage:

32 μM
Administration:

intra-articular injection; once weekly; 8 weeks
Result:

Showed significantly more regular articular cartilage surfaces, a thicker AC layer, a thinner calcified cartilage layer, and a lower osteophyte score.
Increased AC thickness, reduced CC thickness, and increased the AC/CC ratio.
Increased subchondral bone thickness, and significantly reduced the number of TRAP (+) multinucleated osteoclasts in SCB.
Increased aggrecan and type II collagen expression.
Reduced AC destruction and deeper Safranin O staining, with lower Osteoarthritis Research Society International scores.
Increased trabecular bone volume/tissue volume and trabecular number, and reduced trabecular separation in SCB, reducing SCB loss.
Significantly reduced p-p38 MAPK expression.

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.
