CP-547632 hydrochloride is a well-tolerated and orally-bioavailable inhibitor of the VEGFR-2 and basic FGF kinases (IC50s: 11 nM and 9 nM) with antitumor efficacy.
BMS-645737 is an inhibitor of vascular endothelial growth factor (VEGF) receptor-2 and fibroblast growth factor (FGF) receptor-1. BMS-646737 has anti-angiogenic activity and was evaluated in nonclinical studies as a treatment for cancer.
Sucrose octasulfate (SOS), a component of the gastrointestinal protectant sucralfate, is an alkaline aluminum-sucrose complex that inhibits peptic hydrolysis and raises gastric pH, protecting esophageal epithelium against acid injury. It can bind to exosite II of thrombin (KD = ~1.4 μM) and inhibit its catalytic activity (IC50 = 4.5 μM) and, as such, has been used as a surrogate for heparin. Furthermore, SOS has been shown to inhibit tumor growth in mouse melanoma and lung carcinoma models by preventing fibroblast growth factor 2 (FGF-2) binding to endothelial cells and also by removing any pre-bound FGF-2 from these cells (IC50 = ~2 μg/ml).
3-Methylthienyl-carbonyl-JNJ-7706621 is a highly potent and selective inhibitor of cyclin-dependent kinase (CDK). It exhibits impressive IC50 values of 6.4 nM and 2 nM for CDK1 cyclin B and CDK2 cyclin A, respectively. Additionally, 3-Methylthienyl-carbonyl-JNJ-7706621 demonstrates potent inhibition against GSK-3 (IC50 = 0.041 μM) and moderate potency towards CDK4, VEGF-R2, and FGF-R2 (IC50 = 0.11 μM, 0.13 μM, and 0.22 μM, respectively). Its applications in cancer research are noteworthy.
D-Glucosamine-6-sulfate is a naturally occurring glycosaminoglycan. It activates the glmS ribozyme from B. subtilis, a Gram-positive bacterium, when used at a concentration of 200 μM. It has been used to form polyvalent dendrimer conjugates that inhibit angiogenesis and endothelial cell proliferation induced by FGF-2 in vitro and prevent scar tissue formation in a rabbit model of glaucoma surgery.
FGF PDGF VEGF RTK Inhibitor is a potent, reversible, atp-competitive inhibitor against pdgfrβ, fgfr-1, and vegfr-2 (ic50 = 20, 90, and 240 nm, respectively) and effectively suppresses vegf-stimulated proliferation of hmvecs (ec50 = 420 nm).
