The present invention relates to a class of 2-aminothiazoline derivatives of formula I:
1
in which either R
1
is a hydrogen atom or an alkyl radical and R
2
is an alkyl, -alk-NH
2
, —CH
2
—R
3
, —CH
2
—S—R
4
or phenyl radical substituted with a nitro or —NH—C(═NH)CH
3
radical, or R
1
is an alkyl radical and R
2
is a hydrogen atom, R
3
is a (3-6C) cycloalkyl, pyridyl, pyridyl N-oxide, thienyl, thiazolyl, imidazolyl, pyrazinyl, triazolyl or phenyl radical or a phenyl radical substituted with a nitro, hydroxy or carboxyl radical, R
4
represents a pyridyl or pyridyl N-oxide radical, alk represents an alkylene radical, or pharmaceutically acceptable salts thereof, which are useful as inhibitors of inducible NO-synthase.
