A direct C–H arylation of aminoheterocycles with arylhydrazine hydrochlorides was developed. The reaction proceeds via a homolytic aromatic substitution mechanism involving aryl radicals as the intermediates. The new reaction takes place readily at room temperature in air and in the presence of an inexpensive base. Moreover, the reactivity of this radical arylation correlated with the HOMO energy of
The present invention provides agents effective to treat eye diseases, pharmaceutical compositions comprising them, methods for preparing pharmaceuticals for treatment of eye diseases comprising using the agents, use of the agents in manufacture of pharmaceuticals for treatment of eye diseases and methods for treating eye diseases comprising administering the agents or the pharmaceutical compositions. The eye diseases treated by the present invention include particularly glaucoma, especially normal tension glaucoma, or retinitis pigmentosa. The present invention provides the compound of formula (I)
wherein R is as defined in the description.
The present invention provides compounds which can regulate VCP activity. The present invention provides the compound of formula (I)
(R is as defined in the description)
or oxides, esters, prodrugs, pharmaceutically acceptable salts or solvates thereof. The compounds can regulate VCP activity, and thus are useful for treating VCP-mediated diseases such as neurodegenerative diseases.
