MedKoo CAT#: 206058

CAS#: 1360460-82-7 (HCl)

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 HCl is a receptor tyrosine kinase (RTK) inhibitor that primarily inhibits VEGFR2/3, FGFR1-4, PDGFRα/β, c-Kit, and Ret.
In vitro activity: Transforming growth factor-β1 (TGF-β1) is considered to be the most critical fibrogenic factor involved in the development of IPF (idiopathic pulmonary fibrosis) and its function depends on the signal transduction and regulation of Smad and non-Smad. Smad3 is the main activation protein of TGF-β/Smad signalling pathway, regulating a series of gene expression, and promotes fibroblast differentiation and proliferation. The constructed CAGA-NIH3T3 cell line stably transfected with the TGF-β1/Smad3 signalling pathway reporter plasmid was used to detect the effect of anlotinib hydrochloride on TGF-β1/Smad3 signalling pathway. As shown in Figure 5a, luciferases assay showed that anlotinib inhibited the TGFβ1/Smad3 signalling pathway in a dose-dependent manner. According to the results of Luciferases assay, 1 μM was selected as the best effective concentration for subsequent experiments. Further, it was observed that anlotinib hydrochloride significantly inhibited TGF-β1-induced phosphorylation of Smad3 protein, as shown in Figure 5b. Reference: J Pharm Pharmacol. 2020 Jan;72(1):44-55.
In vivo activity: The effect of anlotinib on bleomycin-induced pulmonary fibrosis in mice was evaluated. The histological changes at 14 days are shown in Figure 2a. In the saline group, there was no obvious inflammatory reaction and fibrosis in the lung tissue of mice, and the lung tissue structure was normal. After bleomycin was injected, not only the airway wall was significantly thickened, but also the alveolar structure was disordered. Meanwhile, the lung tissue of mice showed obvious alveolar inflammation, and some alveoli appeared realistic changes and fibrosis. In addition, the mice with bleomycin injection showed higher Ashcroft score than in control group. After anlotinib intervention, the above lesions were alleviated, and the Ashcroft score was significantly reduced (Figure 2b). It was also observed that the content of hydroxyproline in the left lung of mice in bleomycin group was significantly higher than that in saline group, as shown in Figure 2c. In anlotinib-treated group, the hydroxyproline content decreased, indicating that anlotinib inhibited ECM (extracellular matrix) deposition. The effect of anlotinib on the forced vital capacity in bleomycin-induced pulmonary fibrosis mice was also evaluated. The results showed that anlotinib increased the lung capacity of mice (Figure 2d). Reference: J Pharm Pharmacol. 2020 Jan;72(1):44-55.
