Optimisation of imidazole compounds as selective TAAR1 agonists: Discovery of RO5073012

A series of imidazole compounds has been identified which affords potent and selective partial and full agonists of the TAAR1 receptor. Starting from 2-benzyl-imidazoline screening hits, a series of structurally related 2-benzyl- and 4-benzyl-imidazoles was investigated first, but it proved highly challenging to obtain compounds having sufficient selectivity against the adrenergic alpha 2 receptor. This issue could be successfully addressed by modification of the linker region and SAR exploration led to the discovery of highly selective isopropyl-substituted 4-aminomethyl-imidazole compounds. The work culminated in the identification of the selective TAAR1 partial agonist RO5073012 (4-chlorophenyl)-(1H-imidazol-4-ylmethyl)-isopropyl-amine, 24), which has a good pharmacokinetic profile after oral administration in rodents. RO5073012 has been found to be active in a behavioural rat model which is considered indicative for schizophrenia.

Method for the treatment of CNS disorders with substituted 2-imidazoles or imidazole derivatives

The present invention relates a method for treating depression, anxiety disorders, bipolar disorder, attention deficit hyperactivity disorder, stress-related disorders, psychotic disorders such as schizophrenia, neurological diseases such as Parkinson's disease, neurodegenerative disorders such as Alzheimer's disease, epilepsy, migraine, hypertension, substance abuse and metabolic disorders such as eating disorders, diabetes, diabetic complications, obesity, dyslipidemia, disorders of energy consumption and assimilation, disorders and malfunction of body temperature homeostasis, disorders of sleep and circadian rhythm, and cardiovascular disorders which comprises administering to an individual a therapeutically effective amount of a compound of formula I wherein R, R1, R2, A and n are as defined in the specification and to their pharmaceutically active salts. The invention also relates to novel compounds of formula I, pharmaceutical compositions containing them, and methods for their preparation.
