CAS#: 3521-62-8

Description: Erythromycin estolate is a macrolide antibiotic, produced by Streptomyces erythreus. It is the lauryl sulfate salt of the propionic ester of erythromycin. This erythromycin salt acts primarily as a bacteriostatic agent. In sensitive organisms, it inhibits protein synthesis by binding to 50S ribosomal subunits. This binding process inhibits peptidyl transferase activity and interferes with translocation of amino acids during translation and assembly of proteins.

More Info:

Biological target: Erythromycin estolate, erythromycin derivative, is a macrolide antibiotic used in the treatment of a wide variety of bacterial infections.
In vitro activity: As shown in Figure 1B, numbers of ZIKV plaques were reduced more as the concentration of Ery-Est (erythromycin estolate) increased. There were scarcely any plaques formed with the Ery-Est treatment of 10 µM or more, while plaques treated by Ery of any concentrations used in the assay were generally unchanged. This suggests that Ery-Est inhibits ZIKV infection in a dose-dependent manner. Reference: Viruses. 2019 Nov; 11(11): 1064. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6893414/
In vivo activity: Additionally, the ERM (erythromycin) treatment significantly reduced bone loss compared to the PC and JSM treatment groups (Figure 1b,c). Compared to the EtOH group, ERM, JSM, and PC treatment significantly decreased the gene expression of Nfatc1 and RANK, which are osteoclast differentiation-related factors in the gingiva (Figure 2a,b). Furthermore, ERM and JSM treatment significantly downregulated the expression of bone resorption activity-related factors (Acp5, Ctsk) (Figure 2c,d). Interestingly, ERM treatment significantly upregulated Del1 expression, compared to the EtOH group (Figure 2e).
