Guanidine derivatives are provided useful for promoting growth, repair and regeneration of a neuronal axon and for treating neuropathies and myopathies. The compounds have the formula: ##STR1## wherein R.sub.1 is an isopropyl radical, a benzyl radical which is optionally substituted by one or more (C.sub.1 -C.sub.6)alkoxy radicals or a radical: ##STR2## R.sub.2, R.sub.3 and R.sub.4 together with the nitrogen atoms to which they are attached and the carbon atom to which the said nitrogen atoms are attached form a pyrimidine ring of formula II or a pyrimidinium ring of formula IIa: ##STR3##
