Investigation of pyrazolo-sulfonamides as putative small molecule oxytocin receptor agonists

The neuropeptide oxytocin has been implicated in multiple central nervous system functions in mammalian species. Increased levels have been reported to improve trust, alleviate symptoms related to autism and social phobias, and reduce social anxiety. Hoffman-La Roche published a patent claiming to have found potent small molecule oxytocin receptor agonists, smaller than the first non-peptide oxytocin agonist reported, WAY 267,464. We selected two of the more potent compounds from the patent and, in addition, created WAY 267,464 hybrid structures and determined their oxytocin and vasopressin receptor activity. Human embryonic kidney and Chinese hamster ovary cells were used for the expression of oxytocin or vasopressin 1a receptors and activity assessed via IP1 accumulation assays and calcium FLIPR assays. The results concluded that the reported compounds in the patent and the hybrid structures have no activity at the oxytocin or vasopressin 1a receptors.

OXYTOCIN RECEPTOR AGONISTS FOR THE TREATMENT OF CNS DISEASES

The invention relates to the use of a compound of formula I wherein A1 is phenyl or a five or six membered hereroaryl group, containing 1, 2 or 3 heteroatoms, selected from N or S; R1 is hydrogen, lower alkyl, halogen, lower alkyl substituted by halogen or cycloalkyl; A2 is phenyl; R2 is halogen, lower alkyl, lower alkyl substituted by halogen, lower alkoxy substituted by halogen, cyano, S-lower alkyl substituted by halogen, S(O)2-lower alkyl substituted by halogen; n is 1 or 2; or a to pharmaceutically acceptable acid addition salt, to a racemic mixture or to its corresponding enantiomer and/or optical isomers thereof for the treatment of autism, stress, including post traumatic stress disorder, anxiety, including anxiety disorders and depression, schizophrenia, psychiatric disorders and memory loss, alcohol withdrawel, drug addiction and for the treatment of Prader-Willi Syndrom.
