Erythromycin stearate
Based on 24 publication(s) in Google Scholar
Erythromycin stearate is a macrolide antibiotic produced by actinomycete Streptomyces erythreus with a broad spectrum of antimicrobial activity. Erythromycin stearate binds to bacterial 50S ribosomal subunits and inhibits RNA-dependent protein synthesis by blockage of transpeptidation and/or translocation reactions, without affecting synthesis of nucleic acid[1][2]. Erythromycin stearate also exhibits antitumor and neuroprotective effect in different fields of research[3][4].

Erythromycin stearate inhibits growth of P. falciparum with IC50 and IC90 values of 58.2 μM and 104.0 μM, respectively[1].
Erythromycin stearate (10 μM, 100 μM; 24 h, 72 h) shows antioxidant and anti-inflammatory effects and suppresses the accumulation of 4-HNE (p<0.01) and 8-OHdG (p<0.01), reduces Iba-1 (p<0.01) and TNF-α (p<0.01) expression significantly[4].

-
Cell Line:Embryos primary cortical neuron (from the cerebral cortices of 17-day-old Sprague-Dawley rat)
-
Concentration:10, 100 μM
-
Incubation Time:24, 72 hours
-
Result:Improved the viability of cultured neuronal cells in vitro after 3 hours oxygen-glucose deprivation (OGD).
Erythromycin stearate (gastric intubation; 5 mg/kg) protects mice alive even at 120 days after inoculation, but shortens mean survival time in tumor-bearing mice by 4-5 days with dose of 50 mg/kg[3].
Erythromycin stearate (i.h.; single injection; 50 mg/kg) has a protective effect on the rat model with cerebral ischemia reperfusion-injury[4].

Animal Model:Female ddY mice (6-week-old) with EAC cells or CDF mice (6-week-old) with P388 cells[3]
-
Dosage:0.1 mg/kg; 0.5 mg/kg; 10 mg/kg; 30 mg/kg; 50 mg/kg
-
Administration:Gastric intubation; 30-120 days
-
Result:Decreased tumor growth and prolonged the mean survival time of mice from the dose of 5 mg/kg, however, the 50 mg/kg dosage shortened the MST in tumorbearing mice.
-
Animal Model:Male Sprague-Dawley rats (8-week-old, 250-300 g)[4]
-
Dosage:50 mg/kg
-
Administration:Subcutaneous single injection
-
Result:Reduced infarct volume and edema volume, improved neurological deficit.
