MedKoo CAT#: 317864

CAS#: 72509-76-3

Description: Felodipine is a calcium channel blocker (calcium antagonist), used to control hypertension. Felodipine prevents calcium from being released within the muscle cells of the small arteries and thereby causes the muscles to relax and the arteries to dilate or expand. Dilation of arteries reduces blood pressure. Felodipine has little or no effect on the muscles of veins or the heart. Felodipine was approved by the FDA in 1991.

Product Data:
Biological target: Felodipine, a dihydropyridine, is a potent, vasoselective calcium channel antagonist.
In vitro activity: Therefore, to test whether these concentrations were likely to be inducing autophagy, this study examined the effects of low concentrations (50 and 100 nM) of felodipine in cultured primary neurons. Indeed, these concentrations increased the numbers of autolysosomes (suggesting increased autophagic flux) and significantly reduced the percentages of neurons with mutant huntingtin exon 1 aggregates (Fig. 4b, c). Reference: Nat Commun. 2019; 10: 1817. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6472390/
In vivo activity: Treatment with felodipine significantly downregulated the genes associated with osteoclast differentiation. RNA-sequencing and western blotting suggested that felodipine could inhibit bone resorption by suppressing MAPK pathway phosphorylation. Moreover, micro-CT scanning and histological analysis in an ovariectomy (OVX)-induced bone-loss mouse model indicated that felodipine might be a potent drug for preventing osteoporotic fractures.
