Cilengitide
Based on 75 publication(s) in Google Scholar
Cilengitide (EMD 121974) is an integrin (integrin) inhibitor with blood-brain barrier permeability, with IC50 values against human targets as follows: 0.61 nM for αvβ3, 8.4 nM for αvβ5, 14.9 nM for α5β1, 5400 nM for αIIbβ3, 2050 nM for αvβ6, 2350 nM for αvβ8. Cilengitide inhibits the binding of integrins to vitronectin, fibronectin, fibrinogen and LAP (TGF-β), and serves as an internal standard for solid-phase integrin binding assays. Cilengitide inhibits tumor cell viability, induces apoptosis, reduces the phosphorylation levels of STAT3, AKT and mTOR, downregulates the expression of PD-L1, inhibits cell viability and angiogenesis, regulates anti-tumor immune responses and slows tumor growth. Cilengitide can be used in research related to glioblastoma, melanoma, advanced solid tumors and refractory brain tumors.

Cilengitide (1-1000 µg/mL; 24-72 h) inhibits the viability of B16 and A375 cells in a time- and dose-dependent manner[2].
Cilengitide (5-10 µg/mL; two weeks) inhibits colony formation of B16 and A375 melanoma cells[2].
Cilengitide (5-10 µg/mL; 12 h) induces apoptosis in B16 and A375 melanoma cells[2].
Cilengitide (5 µg/mL; 12 h) alters the transcriptome of B16 melanoma cells, regulates genes and pathways involved in cell growth, apoptosis and integrin signaling pathways, including reducing the phosphorylation levels of AKT and mTOR[2].
Immunofluorescence staining shows that Cilengitide (5 µg/mL; 12 h) reduces PD-L1 expression levels in B16 and A375 melanoma cells, decreases the proportion of PD-L1-positive B16 and A375 melanoma cells, and lowers the positive rate from 38.1-41.1% to 17.9-18.2% after 12 hours of incubation[2].
Cilengitide (5-20 µg/mL; 12 h) reduces the expression level of PD-L1 and the phosphorylation level of STAT3Tyr705 in B16 and A375 melanoma cells, without altering the expression level of total STAT3 protein[2].
Cilengitide (5 µg/mL; 12 h) downregulates PD-L1 expression in B16 and A375 melanoma cells by reducing the phosphorylation level of STAT3, while IL-6-induced STAT3 activation reverses this PD-L1 downregulation[2].
Cilengitide (6.4 nM-20 μM; 1 h) exhibits the strongest inhibitory effect on the binding of human αvβ3 integrin to vitronectin (IC50 = 0.61 nM), while it also shows high affinity for αvβ5 (IC50 = 8.4 nM) and α5β1 (IC50 = 14.9 nM). In contrast, its affinity for αvβ6, αvβ8 and αIIbβ3 integrins is significantly reduced[1].
Cilengitide (2 μM) inhibits integrin-mediated adhesion of human umbilical vein endothelial cells to vitronectin, with an IC50 of 2 μM[3].

Cilengitide (10-250 μg; intraperitoneal injection; three times per week) inhibits the tumor growth of M21-L melanoma in nude mice in a dose-dependent manner[3].
Cilengitide (100 μg; i.p.) results in 100% survival rate and nearly complete tumor clearance in nude mice bearing medulloblastoma and glioblastoma xenografts at day 28[3].
