Description:

WARNING: This product is for research use only, not for human or veterinary use.

Clarithromycin is an antibiotic used to treat various bacterial infections. This includes strep throat, pneumonia, skin infections, H. pylori infection, and Lyme disease, among others. Clarithromycin was developed in 1980. It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system. Clarithromycin prevents bacteria by acting as a protein synthesis inhibitor. It binds to 23S rRNA, a component of the 50S subunit of the bacterial ribosome, thus inhibiting the translation of peptides.

Biological target:

Clarithromycin is a macrolide antibiotic and a CYP3A4 inhibitor.

In vitro activity:

Moreover, both hERG1 silencing and E4031 reduced the effects of Cla (clarithromycin) on LC3 conversion (Fig. 3a), AVOs (Figs. (Figs. 3b and S3b) and vacuoles (Fig. S3c) formation. These data indicate that Cla exerts its effect on CRC cell autophagy, by modulating hERG1. Reference: Cell Death Dis. 2020 Mar; 11(3): 161. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7052256/

In vivo activity:

Post-SAH 50 mg/kg CAM (clarithromycin) treatment most effectively improved neurological scores and brain water content at 24 and 48 h and reduced immunoglobulin G extravasation at 24 h compared with vehicle-treated SAH mice (p < 0.01). Western blotting showed that post-SAH BBB disruption was associated with increased expressions of periostin, phosphorylated signal transducer and activator of transcription 1 and 3, matrix metalloproteinase-9, and the consequent degradation of zonula occludens-1, which were suppressed by 50 mg/kg CAM treatment (p < 0.05, respectively, versus vehicle-treated SAH mice).

Note: There can be variations in solubility for the same chemical from different vendors or different batches from the same vendor. The following factors can affect the solubility of the same chemical: solvent used for crystallization, residual solvent content, polymorphism, salt versus free form, degree of hydration, solvent temperature. Please use the solubility data as a reference only. Warming and sonication will facilitate dissolving. Still have questions? Please contact our Technical Support scientists.
