MedKoo CAT#: 202436
Description: Regorafenib, also known as BAY 73-4506 ; is an orally bioavailable small molecule with potential antiangiogenic and antineoplastic activities. Regorafenib binds to and inhibits vascular endothelial growth factor receptors (VEGFRs) 2 and 3, and Ret, Kit, PDGFR and Raf kinases, which may result in the inhibition of tumor angiogenesis and tumor cell proliferation. Regorafenib demonstrated to increase the overall survival of patients with metastatic colorectal cancer and has been approved by the US FDA on September 27, 2012.

|Biological target:||Regorafenib (BAY 73-4506) is a multi-targeted receptor tyrosine kinase inhibitor with IC50s of 13/4.2/46, 22, 7, 1.5 and 2.5 nM for VEGFR1/2/3, PDGFRβ, Kit, RET and Raf-1, respectively.|
|In vitro activity:||To identify the toxicity of regorafenib, this study performed MTT assay on CT26 and HT29 cells. Cell viability was decreased after regorafenib treatment as dose and time dependent manner (Fig. 1A-B). The IC50 of regorafenib in CT26 and HT29 is 22 μM and 20 μM at 24 h, respectively. Importantly, regorafenib may also suppress NF-κB activation as dose and time dependent manner (Fig. 1C-D). Furthermore, EGF induced NF-κB activity may be effectively suppressed by regorafenib as showed in Fig. 1E-F. EGF-induced EGFR phosphorylation was successfully diminished by regorafenib as illustrated in Fig. 1G. Erlotinib (EGFR inhibitor) obviously downregulated the phosphorylation of PKCδ, ERK, AKT and NF-κB (Fig. 1H-I). In Fig. 1J-L, the activation of downstream kinases (PKCδ, ERK, and AKT) and transcription factor (NF-κB) in EGFR signal transduction were all markedly decreased by regorafenib. In sum, regorafenib can effectively suppress EGFR signal transduction in CRC cells. Reference: Biomed Pharmacother. 2020 Aug;128:110319. https://pubmed.ncbi.nlm.nih.gov/32502841/|
|In vivo activity:||Regorafenib 5 mg/kg/day, corresponding to about 50% of the recommended dosage for human based on clinical and preclinical pharmacokinetic data, exerted antitumor efficacy in both orthotopic and subcutaneous immune-competent liver cancer models (figure 1A). The difference in tumor growth measured at the end of the mouse study may reflect the combined effects of decreased cell proliferation (Ki67 staining), decreased tumor angiogenesis (CD31 staining), and increased tumor cell apoptosis (TUNEL assay) by regorafenib (figure 1B). Regorafenib increased CD4+ and CD8+ T cell infiltration into tumors, increased expression of genes related to T cell activation, antigen presentation, and macrophage activation, and suppressed genes related to angiogenesis (figure 1B, C,online supplemental table S2). While regorafenib induce cancer cell apoptosis dose dependently (online supplemental figure S1A, B), higher dosage of regorafenib inhibited T cell proliferation and activation in vitro (figure 1D, online supplemental figure S1C), suggesting that higher dosage of regorafenib may not be associated with better immune modulatory effects.
