The purpose of this study is to research toxicity and antiviral activity of the aminomethanesulphonic acid (I) and its N-methyl (II), N-tert-butylderivatives (III) and reference drug (Tamiflu). We have determined the maximally tolerant (non-toxic) doses (MTD) for these compounds. Oral LD50 of I – III: > 5000 mg/kg (rat, male) – practically non-toxic. On tissue culture CAC influenza activity was determined in a dose of 10-3 M as for test compounds so for the reference drug (Tamiflu).enaminomethanesulphonic acidtoxicityantiviral actionArticle
