Taxifolin (Dihydroquercetin) is a flavonoid in many plants such as Taxus chinensis, Siberian larch, Cedrus deodara and so on.

Sorafenib tosylate (Bay 43-9006) is a potent multikinase inhibitor (IC50s: 6/20/22 nM for Raf-1/VEGFR-3/B-Raf).

Regorafenib (BAY 73-4506) is an orally active, multi-targeted receptor tyrosine kinase inhibitor that inhibits RET, C-RAF, VEGFR2, c-Kit, VEGFR1, and PDGFRβ, exhibiting both antitumor and anti-angiogenic activity.

Lenvatinib mesylate (E7080 (mesylate)) is an oral and multi-targeted inhibitor of VEGFR1-3, FGFR1-4, PDGFR, KIT, and RET, with potent antitumor activities.

Pazopanib (GW786034) is an inhibitor of protein tyrosine kinases that inhibits VEGFR1, VEGFR2, VEGFR3, PDGFRβ, c-Kit, FGFR1, and c-Fms (IC50=10/30/47/84/74/140/146 nM). Pazopanib has antitumor activity.

Tanshinone IIA (Tanshinone B) is a diterpene quinone natural product that targets the protein kinase domain of VEGF/VEGFR2. Tanshinone IIA inhibits angiogenesis and exhibits anti-inflammatory, antioxidant, and therapeutic activities against coronary heart disease.

Sunitinib (SU 11248) is a multi-targeted receptor tyrosine kinase (RTK) inhibitor that inhibits VEGFR2 and PDGFRβ (IC50=80/2 nM). It exhibits antitumor activity and is used for treating kidney cancer and gastrointestinal tumors.

Nintedanib (Intedanib) is a triple vascular kinase inhibitor that inhibits VEGFR1, VEGFR2, and VEGFR3 (IC50=34/13/13 nM), FGFR1, FGFR2, and FGFR3 (IC50=69/37/108 nM), PDGFRα, and PDGFRβ (IC50=59/65 nM). Nintedanib has antitumor activity and inhibits tumor growth by inhibiting angiogenesis.
