MedKoo CAT#: 206958

CAS#: 1058156-90-3 (free base)

Description: Anlotinib, also known as AL3818 and Catequentinib, is a receptor tyrosine kinase (RTK) inhibitor with potential antineoplastic and anti-angiogenic activities. Upon administration, anlotininib targets multiple RTKs, including vascular endothelial growth factor receptor type 2 (VEGFR2) and type 3 (VEGFR3). This agent may both inhibit angiogenesis and halt tumor cell growth.

Biological target: Anlotinib (AL3818) is a highly potent and selective VEGFR2 inhibitor with IC50 less than 1 nM.
In vitro activity: To investigate the anti-angiogenic activity of anlotinib, the effect of anlotinib on the migration of HUVEC in Transwell assays was examined. As shown in Figure 4A, anlotinib inhibited the migration of HUVEC to the lower side of the filter in the Transwell chamber in response to VEGF stimulation. This effect was concentration dependent, with an IC50 value of 0.1 nmol/L. At a concentration of 100 nmol/L, sunitinib also significantly inhibited the migration of HUVEC. It has been reported that VEGF cannot induce tube formation of HUVEC when cultured on Matrigel, so 20% FBS was selected as a stimulating factor to evaluate the effect of anlotinib on the tube formation of HUVEC. As shown in Figure 4B, anlotinib inhibited the ability of HUVEC to form tubes in a concentration‐dependent way. Following treatment with 100 nmol/L anlotinib, few enclosed tubes were detected.

In vivo activity: The in vivo antitumor potential of anlotinib was evaluated in the human colon cancer SW620 xenograft model. Once-daily oral dose of anlotinib caused dose-dependent inhibition of tumor growth (Figure 5A,C), inhibiting tumor growth by 83% compared with controls at a dose of 3 mg/kg. By comparison, the dose of sunitinib required to achieve comparable efficacy was 50 mg/kg in this model. Moreover, anlotinib had little effect on bodyweight in mice during the course of the experiment in all groups (Figure 5B). We further assessed tumor angiogenesis by measuring microvessel density in extracted tumors using an immunohistochemical analysis for CD31, an endothelial cell marker. Anlotinib induced a significant decrease in CD31‐positive microvessels, yielding inhibition rates of 48.9%, 76.3% and 91.2% at doses of 0.75, 1.5 and 3 mg/kg, respectively (Figure 5D). By comparison, sunitinib at a dose of 50 mg/kg inhibited microvessel density by 63.6%. Reference: Cancer Sci. 2018 Apr;109(4):1207-1219. https://www.ncbi.nlm.nih.gov/pmc/articles/pmid/29446853/
