TG 100801 (TG-100801; TG100801) is an ester prodrug of TG-100572 (TG 100572). TG100801 is a newly discovered, highly effective dual inhibitor of VEGFr2 and Src family (Src/YES) kinases that may be applied to the management of age-related macular degeneration, or AMD. With IC50s of 2, 7, 2, 16, 13, 5, 0.5, 6, 0.1, 0.4, 1, 0.2 nM, respectively, it can be topically applied and inhibit RTK (receptor tyrosine kinases) and Src kinases, including VEGFR1, VEGFR2, FGFR1, FGFR2, PDGFRβ, Fgr, Fyn, Hck, Lck, Lyn, Src, and Yes.
| Targets |
VEGFR1 (IC50 = 2 nM); VEGFR2 (IC50 = 7 nM); FGFR1 (IC50 = 2 nM); FGFR2 (IC50 = 16 nM); PDGFRβ (IC50 = 13 nM)

| ln Vitro |
TG 100801, a prodrug applied topically and administered as an eye drop, is easily changed in the eye to become the active TG 100572.It has been demonstrated that TG 100572 inhibits the proliferation of hRMVEC cells, with an IC50 of 610±72 nM[1]. An ester is produced by derivitization of a phenolic moiety in TG100572 to form TG 100801. It exhibits a superb equilibrium between the rate of hydrolysis and stability (chemical and physical). While the ester group in TG 100801 prevents important interactions with kinase active sites, it lacks significant anti-kinase activity when used alone. However, TG 100801 becomes active very quickly when exposed to esterases, which are prevalent in mammalian tissues. TG 100572 exhibits sub-nanomolar activity against RTK and members of the Src family, including VEGFR1 and R2, FGFR1 and R2, and PDGFRβ. TG 100572 inhibits the proliferation of vascular endothelial cells (ED50=610±71 nM) and prevents extracellular signal-regulated kinase from being phosphorylated by VEGF. In cultures of endothelial cells that are rapidly proliferating but not quiescent, TG 100572 induces apoptosis[2].

| ln Vivo |
TG 100801 demonstrates good efficacy in the laser-induced choroidal neovascularization model, with poor systemic circulation and excellent ocular pharmacokinetics. In 30 min (Tmax) = 0.5 h, TG 100572 reaches a concentration of 23.4 µM (Cmax) in the choroid and sclera. TG 100572 levels in the retina, however, are comparatively low. TG 100572 has a very short half-life in ocular tissues, so in order to maintain proper drug levels in the eye, the compound is applied topically at least once every day. In formulations utilizing TG 100572, the highest concentration that can be attained is 0.7% w/v[1]. After TG 100801 is applied topically, neither TG 100801 nor TG 100572 are detectable in plasma, and even with extended dosing regimens, negative safety signals (like weight loss) are not seen. Topical TG 100801 suppresses retinal vein occlusion and fluorescein leakage from the vasculature, as well as laser-induced choroidal neovascularlization in mice. It also reduces retinal thickening as determined by optical coherence tomography in a rat model. When TG 100572 is administered systemically to mice in a model of laser-induced choroidal neovascularization (CNV), the condition is significantly suppressed, but there is also a weight loss that may indicate systemic toxicity[2].

| Animal Protocol |
Rats: Either 10 µL of TG 100801 (in the form of a 0.3, 0.6, or 1% solution) or vehicle is applied topically to both eyes of long Evans rats. Over a three-day period, each eye receives a total of five topical applications: dosing is done twice on Day 2 and once in the morning of Day 3, one hour before and six hours after laser-induced thrombosis. There are two methods for assessing retinal edema an hour after the last topical application[2].
