Velutin
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 Vitro
Velutin (2-200 μM; 10 min) potently scavenges ABTS free radicals in cell-free assays, with an EC50 value of 23.13 μM[1].
Velutin (0.01-1 mM; pre-incubated with tyrosinase for 30 min, followed by incubation with L-tyrosine for 10 min) inhibits mushroom tyrosinase activity in cell-free assays, with an IC50 of 910.1 μM[1].
Velutin (10 μM; 48 h) completely inhibits α-MSH-induced melanogenesis in B16F10 mouse melanoma cells[1].
At a concentration of 10 μM with 48 h incubation, velutin inhibits α-MSH-induced intracellular tyrosinase activity by 87% in B16F10 mouse melanoma cells[1].
Velutin (0-32 μM; 24-48 h) exhibits no cytotoxicity toward primary mouse chondrocytes, with the maximum concentration reaching 32 μM after 24 h or 48 h of incubation[2].
Velutin (32 μM; 7 days) protects primary mouse chondrocytes against IL-1β-induced inflammation and extracellular matrix degradation after 7 days of incubation[2].
Velutin (4 μM; 2 h) inhibits RANKL-induced activation of p38 MAPK in mouse bone marrow-derived macrophages[2].

Cell Line:B16F10 murine melanoma cells
-
Concentration:20 μM
-
Incubation Time:24 h
-
Result:Showed no significant cytotoxicity, with cell viability remaining near 100% at 20 μM.
In Vivo
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].

-
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.
