Synthetic 5-ethoxy-2-ethylthiobenzimidazole. bemitil analog (benzimidazole scaffold, 5-ethoxy substitution). Antihypoxant and hepatoprotective; never commercialised.
mechanism confidence: medium
Synthetic 5-ethoxy-2-ethylthiobenzimidazole. same benzimidazole scaffold as bemitil, with 5-ethoxy substitution that shifts activity profile. Mechanism: antihypoxant + hepatoprotective + regenerative. Direct findings:
- liver regeneration after partial hepatectomy. ethomersol (5-ethoxy-2-ethylthiobenzimidazole) comparable to bemitil (2-ethylthiobenzimidazole), both accelerate liver mass restoration, increase total nucleic acids, in combination with yakton (succinate mono-(2-dimethylamino)ethyl ester) (Gaivoronskaya-Okovityy-Kolyshev-Shustov-Bolotova 2013)
- antihypoxic activity. 7 new 1-(tietanyl-3)2-benzimidazole derivatives tested on 4 hypoxia models, compared to bemitil and ethomersol reference; thietazole has lowest toxicity (Sadykov 2009)
- condensed benzimidazole derivatives with antioxidant activity have antihypoxic activity (Spasov-Kosolapov-Anisimova-Zhukovskaya 2019)

- Liver regeneration post-partial hepatectomy: ethomersol (5-ethoxy-2-ethylthiobenzimidazole) accelerates liver mass restoration, increases total nucleic acids, comparable to bemitil (Gaivoronskaya-Okovityy-Kolyshev-Shustov-Bolotova 2013)
- 7 new 1-(tietanyl-3)2-benzimidazole derivatives tested on 4 hypoxia models, compared to bemitil + ethomersol reference; thietazole lowest toxicity (Sadykov 2009)
- Condensed benzimidazole derivatives with 3,4-dihydroxyphenyl substituent show high antioxidant activity and antihypoxic activity (Spasov 2019)
- Actoprotector clinical application: bemitil + ethomersol for disaster medicine, military medicine, radiation consequence mitigation (Lyazikov-Pitkevich-Melnik 2011)
grade: Moderate. Direct studies on ethomersol specifically (vs bemitil) are limited. The compound is included as a reference in studies of new benzimidazole derivatives.
