MedKoo CAT#: 200135

CAS#: 1218779-75-9 (mesylate)

Description: Rivoceranib, also known as Apatinib and YN-968D1, is an orally bioavailable, small-molecule receptor tyrosine kinase inhibitor with potential antiangiogenic and antineoplastic activities. The free-base form is also known as Rivoceranib. Apatinib selectively binds to and inhibits vascular endothelial growth factor receptor 2, which may inhibit VEGF-stimulated endothelial cell migration and proliferation and decrease tumor microvessel density. In addition, this agent mildly inhibits c-Kit and c-SRC tyrosine kinases.

More Info: Related: 1218779-75-9 (Apatinib mesylate salt) 811803-05-1 (Apatinib free base). Apatinib, also known as YN968D1, is a tyrosine kinase inhibitor that selectively inhibits the vascular endothelial growth factor receptor-2 (VEGFR2, also known as KDR). It is an orally bioavailable, small molecule agent which is thought to inhibit angiogenesis in cancer cells; specifically apatinib inhibits VEGF-mediated endothelial cell migration and proliferation thus blocking new blood vessel formation in tumor tissue. This agent also mildly inhibits c-Kit and c-SRC tyrosine kinases.    History of Apatinib: Apatinib was first synthesized by Advenchen Laboratories in California, USA and is being developed by Jiangsu Hengrui Medicine (China), LSK BioPartners (US) and Bukwang Pharmaceutical Company (Korea). It is an investigational cancer drug currently undergoing clinical trials as a potential targeted treatment for metastatic gastric carcinoma, metastatic breast cancer and advanced hepatocellular carcinoma. (source: http://en.wikipedia.org/wiki/Apatinib).   Development status of Apatinib: There is a Phase II/III study recruiting patients in China to determine whether apatinib can improve progression free survival compared with placebo in patients with metastatic gastric carcinoma who have failed two lines of chemotherapy (September, 2009). As of November, 2010, two additional Phase 2 clinical studies have been initiated for apatinib in metastatic triple-negative breast cancer patients and advanced hepatocellular carcinoma. On March 7, 2011, Bukwang announced that it filed an IND to the Korean FDA to begin Human clinical studies of Apatinib in Phase 2.  (source: http://en.wikipedia.org/wiki/Apatinib).    

Biological target: Apatinib mesylate (YN968D1, Rivoceranib) is a potent inhibitor of the VEGF signaling pathway with IC50 values of 1 nM, 13 nM, 429 nM and 530 nM for VEGFR-2, Ret (c-Ret), c-Kit and c-Src, respectively.
In vitro activity: To evaluate the role of Apatinib in osteosarcoma cells, flow cytometry was used to analyze the cells after Annexin V-FITC and propidium iodide (PI) staining. Apatinib-induced apoptosis significantly when compared with the control group (Figure 3a). As a key indicator of apoptosis, the level of cleaved-PARP increased after treatment with Apatinib for 48 h, or with 10 μM Apatinib for different time points (Figure 3d). To determine whether Apatinib inhibited cell proliferation by inducing cell-cycle arrest, the distribution of cell cycle in osteosarcoma cells treated with Apatinib was evaluated. As shown in Figure 3b, accumulation of cells by Apatinib resulted in the G0/G1 phase, whereas a corresponding reduction in both KHOS and MG63 cells in the G2/M and S phases. The expression of cyclin D1 decreased after treatment with Apatinib, as analyzed by western blot (Figure 3d). Terminal deoxynucleotidyl transferase-mediated nick-end labeling staining (TUNEL staining) were used to confirm apoptosis. Treatment with Apatinib increased TUNEL-positive cells when compared with the control (Figure 3c). All the data suggest that Apatinib induces apoptosis and G0/G1-phase arrest.

In vivo activity: Apatinib was valid in tumor growth inhibition in vivo. The tumor volume decreased when compared with the control group (Figures 7a and b). In accordance with the in vitro experiment, Figure 7c shows that Apatinib treatment increased the level of LC3-II and Bax, whereas the level of BCL-2 and VEGFR2 decreased in vivo. Immunohistochemistry showed that Apatinib decreased the expression of VEGFR2, p-STAT3 and BCL-2 in tumors formed by KHOS cells (Figure 7d). All the results revealed that Apatinib inhibited the growth of osteosarcoma in vivo. Reference: Cell Death Dis. 2017 Aug 24;8(8):e3015. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5596600/
