Niclosamide sodium is an antihelmintic that is active against most tapeworms. | [Uses]
Niclosamide (BAY2353) sodium is an orally active antihelminthic agent used in parasitic infection research[1]. Niclosamide sodium is a STAT3 inhibitor with an IC50 of 0.25 μM in HeLa cells[4]. Niclosamide sodium has biological activities against cancer, and inhibits DNA replication in Vero E6 cells[2][3][5]. | [Production Methods]
The production of niclosamide-olamine begins with the synthesis of niclosamide, typically via a condensation reaction between 5-chlorosalicylic acid and 2-chloro-4-nitroaniline in the presence of a chlorinating agent such as phosphorus trichloride, often carried out in a solvent like chlorobenzene at elevated temperatures. The resulting niclosamide is then purified through recrystallisation. To form the sodium salt, niclosamide is then reacted with sodium hydroxide in aqueous or alcoholic solution, converting the phenolic hydroxyl group into its sodium salt form. | [Mechanism of action]
Respiratory & stomach action. Acts by uncoupling oxidative phosphorylation in the tapeworm | [in vivo]
Niclosamide sodium (oral gavage; 100 mg/kg, 200 mg/kg; once a week; 8 weeks) treatment inhibits adrenocortical carcinoma tumor growth in vivo[3]. | Animal Model: | Nu+/Nu+ mice injected with NCI-H295R cells[3] | | Dosage: | 100 mg/kg, 200 mg/kg | | Administration: | Oral gavage; 100 mg/kg, 200 mg/kg; once a week; 8 weeks | | Result: | Showed a 60%-80% inhibition in tumor growth, as compared to the control group. |
