In intact RVSMC cells and in membrane preparations, telmisartan inhibits the binding of 125I-AngII to AT1 receptors in a concentration-dependent manner, with an IC50 of 9.2 ± 0.8 nM. In the same experimental conditions, angiotensin II displaces 125I-AngII with an IC50 value of 2.9 ± 0.5 nM. The specific binding of [3H]telmisartan to SMC membranes is displaced by unlabeled telmisartan with an IC50 of 7.7 ± 1.8 nM and by cold AngII with an IC50 of 32.7 ± 5.7 nM [1]. Telmisartan treatment (100 μM) reduces the proliferation of three EAC cell lines (OE19, OE33, and SKGT-4), induces cell cycle arrest in G0/G1 phase and regulates cell cycle-related proteins in EAC cells, and induces the phosphorylation of AMPK and regulates cell cycle-related proteins via the AMPK/mTOR pathway in EAC cells. Telmisartan inhibits the activation of RTKs, downstream effectors and cell cycle-related proteins[5].

Protocol
Cell proliferation is assayed using the CCK-8 cell counting kit. Briefly, 5×103 cells are seeded into each well of a 96-well plate and cultured in 100 μL of RPMI-1640 supplemented with 10% FBS. After 24 h, ARBs (telmisartan, irbesartan, losartan, and valsartan at 0, 1, 10, or 100 μM) or vehicle is added to each well, and cells are cultured for an additional 48 h. CCK-8 reagent (10 μL) is added to each well, and the plates are incubated at 37°C for 3 h. The absorbance is measured at 450 nm using a microplate reader.
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Male athymic mice (BALB/c-nu/nu; 6 weeks old; 20-25 g) are maintained under specific pathogen-free conditions using a laminar airflow rack. The mice have continuous free access to sterilized (γ-irradiated) food and autoclaved water. Each mouse is subcutaneously inoculated with OE19 cells (5×106 cells per animal) in the flank. One week later, the xenografts are identifiable as masses with a maximal diameter > 4 mm. The animals are randomly assigned to treatment with telmisartan (50 μg per day) or diluent only (control). The telmisartan group is intraperitoneally (i.p.) injected five times per week with 2 mg/kg telmisartan for four weeks; the control group is administered 5% DMSO alone for four weeks. Tumor growth is monitored daily by the same investigators, and tumor size is measured weekly. The tumor volume (mm3) is calculated as the tumor length (mm) × tumor width (mm)2/2. All animals are sacrificed on day 22 after treatment, and all animals survive during this period. Between-group differences in tumor growth are analyzed by two-way ANOVA.
