Erythromycin thiocyanate is a macrolide antibiotic produced by actinomycete Streptomyces erythreus with a broad spectrum of antimicrobial activity. Erythromycin thiocyanate 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 thiocyanate also exhibits antitumor and neuroprotective effect in different fields of research^[3][4].

In Vitro

Erythromycin thiocyanate inhibits growth of P. falciparum with IC₅₀ and IC₉₀ values of 58.2 μM and 104.0 μM, respectively^[1].
Erythromycin thiocyanate (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).

In Vivo

Erythromycin thiocyanate (gastric intubation; 0.1-50 mg/kg; 30-120 days) decreases tumor growth and prolong the survival time of mice from dose of 5 mg/kg in mice^[3].
Erythromycin thiocyanate (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 thiocyanate (i.h.; single injection; 50 mg/kg) has a protective effect on the rat model with cerebral ischemia reperfusion-injury^[4].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

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:

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
