EG00229 (EG-00229) is a novel and potent Neuropilin 1 (NRP1) receptor antagonist with anticancer activity. It acts by selectively inhibiting VEGF-A binding to NRP1 b1 domain with an IC50 of 3 μM, but has no effect on VEGFA binding to VEGFR-1 and VEGFR-2. EG00229 inhibits VEGFA binding to NRP1.

Biological Activity
| ln Vitro | Over the course of a 48-hour incubation, treatment with EG00229 (Compound 2; 0-100 μM; A549 cells) significantly reduces cell viability[1]. In endothelial cells, EG00229 (Compound 2) exhibits a reduction in VEGFR2 phosphorylation and a suppression of VEGF-A binding to NRP1. HUVECs have also been shown to inhibit endothelial cell migration[1]. Compound 2, EG00229, exhibits a selectivity of 8 μM in inhibiting radiolabeled 125I-VEGF-A binding to porcine aortic endothelial (PAE)/NRP1 cells, but not effecting VEGFR2-expressing cells. Moreover, EG00229 similarly and potently blocks VEGF-A binding to NRP1-expressing lung carcinoma A549 and prostate cancer DU145 cells, but not to VEGFR1 or VEGFR2. EG00229, with an IC50 of 23 μM, also inhibits the binding of VEGF-A to human umbilical vein endothelial cells (HUVECs), which express VEGFR2, VEGFR1, and NRP1[1]. |
| ln Vivo | The intraperitoneal injection of EG00229 (0-10 mg/kg) administered three times a week for four weeks to NSG mice significantly inhibits tumor growth and evident vascularization[2]. |
| Cell Assay |
Cell Viability Assay[1] Cell Types: A549 cells Tested Concentrations: 0 µM, 10 μM, 30 μM, 100 μM Incubation Duration: 48 hrs (hours) Experimental Results: Caused a significant reduction in cell viability. |
| Animal Protocol |
Animal/Disease Models: 6-week old female NOD scid IL2 receptor gamma chain knockout mice (NSG mice) with ECS cells[2] Doses: 0 mg/kg, 10 mg/kg Route of Administration: intraperitoneal (ip)injection; three times per week; for 4 weeks Experimental Results: Reduces tumor growth and visible vascularization. |

| Additional Infomation | EG00229 is a member of the class of thiophenes that is thiophene substituted by a carbonyl-L-arginine and (2,1,3-benzothiadiazole-4-sulfonyl)amino groups at positions 2 and 3. It is an inhibitor of the neuropilin-1 and VEGF-A interaction and a potential anti-cancer agent. It has a role as an antineoplastic agent, a neuropilin receptor antagonist and an angiogenesis inhibitor. It is a benzothiadiazole, a sulfonamide, a member of thiophenes, a secondary carboxamide, a L-arginine derivative and a dicarboxylic acid monoamide. |
