| In Vitro | TG 100572 shows sub-nanomolar activity against the Src family as well as RTK such as VEGFR1 and R2, FGFR1 and R2, and PDGFRβ. TG 100572 inhibits vascular endothelial cell proliferation (ED50=610±71 nM) and blocks VEGF-induced phosphorylation of extracellular signal-regulated kinase. TG 100572 induces apoptosis in rapidly proliferating, but not quiescent, endothelial cell cultures[1]. TG 100572 is shown to inhibit hRMVEC cell proliferation, with an IC50 of 610±72 nM. This suggests that TG 100572 has the therapeutic potential to inhibit VEGF function in ocular endothelial cells, a contributing factor to pathological angiogenesis in diseases such as AMD and PDR[2]. |
| In Vivo | Systemic delivery of TG 100572 in a murine model of laser-induced choroidal neovascularization (CNV) causes significant suppression of CNV, but with an associated weight loss suggestive of systemic toxicity[1]. A concentration of 23.4 µM (Cmax) of TG 100572 is reached in 30 min (Tmax)=0.5 h) in the choroid and the sclera. However, the levels of TG 100572 in the retina are relatively low. The half-life of TG 100572 in ocular tissues is very short; hence, the compound is administered topically minimum t.i.d. to maintain appropriate drug levels in the eye. The maximum concentration one can achieve in formulations using TG 100572 is 0.7% w/v[2]. |
| Cell Assay | For proliferation assays, human retinal microvascular EC plated in 96-well cluster plates are cultured for 48 hr in the presence of either TG 100572 (2 nM-5 µM) or DMSO; medium contained 10% FBS, 50 µg/mL heparin, and 50 ng/mL rhVEGF. Cell numbers are then assessed using an XTT-based assay[1]. |
| Animal Admin | Mice: C57BL/6 mice (15-20 g) are dosed i.p. twice daily for 4 days with 5 mg/ kg TG 100572, followed by a single dose on Day 5, 5 hr after which plasma samples are taken, animals euthanized, and eyes explanted. Alternatively, mice are dosed topically with either TG 100572 or related prodrugs (e.g., TG 100801) by delivering a single 10 µL drop to both eyes for a total of two days, and both plasma and eyes harvested prior to or 0.5, 1, 3, 5, or 7 hr after the Day 2 dosing[1]. |
