Amlodipine maleate is a dihydropyridine calcium channel blocker, acts as an orally active antianginal agent. Amlodipine maleate blocks the voltage-dependent L-type calcium channels, thereby inhibiting the initial influx of calcium. Amlodipine maleate can be used for the research of high blood pressure and cancer.

: Amlodipine maleate purchased from MedChemExpress. Usage Cited in: Food Chem Toxicol. 2025 Feb 10:115317. [Abstract]; A CCK-8 assay was used to detect the effect of AMs on the proliferation of Ishikawa cells. The results showed that the half-maximal inhibitory concentration (IC₅₀) of Amlodipine (AM) against Ishikawa cells (at 72 h) was 12.36 μM.

: Amlodipine maleate purchased from MedChemExpress. Usage Cited in: Food Chem Toxicol. 2025 Feb 10:115317. [Abstract]; Cell apoptosis rate was detected by flow cytometry using Annexin-V/PI staining. The results showed that the apoptotic rate of the Amlodipine (AM) (15 μM; 12 h)-treated Ishikawa cells was 16.8%, which was 2.16-fold higher than that in cells treated with DMSO.

: Amlodipine maleate purchased from MedChemExpress. Usage Cited in: Exp Mol Med. 2021 Apr;53(4):572-590. [Abstract]; Rat GMCs pretreated with the calcium channel blocker Amlodipine (10μM), inhibitors of PKC (Go6983; 10μM), c-Raf (AZ628, 10μM) and MEK1/2 (U0126, 10μM) for 30min were stimulated with sublytic C5b-9 for 4 0min or 2h. The intracellular calcium was determined by Fluo-4 AM. The results showed that Amlodipine effectively blocked the rise in intracellular calcium levels in rat GMCs induced by 40 min of sublytic C5b-9 stimulation.

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
