Various carbonyl amides are employed in vitro and in vivo as non-nucleoside inhibitors of a reverse transcriptase, and particularly of HIV reverse transcriptase. Therefore, contemplated compounds may be employed in the treatment of HIV infected patients. Further contemplated aspects include pharmaceutical compositions comprising therapeutically effective amounts of contemplated compounds.

Synthesis and characterization of 8-aminoquinolines, substituted by electron donating groups, as high-affinity copper chelators for the treatment of Alzheimer's disease
Résumé The deregulation of copper homeostasis generates copper–amyloid aggregation and strongly participates in neuron damage in the brains of patients with Alzheimer's disease. Therefore, copper chelators able to regulate copper homeostasis should be considered as potential therapeutic agents. On the basis of a bidentate amine side chain attached at the 2-position of an 8-aminoquinoline motif, a series of low-molecular-weight copper chelators have been designed to act as specific tetradentate Cu(II) chelators. The affinity of these ligands for Cu(II) and their selectivity for Cu(II) with respect to Zn(II) are reported. These ligands provide a square planar tetradentate coordination sphere that should be suitable to extract copper (II) from copper–amyloid complexes, and are therefore expected to regulate copper homeostasis in vivo.
