Abcam Signs Licence With The University Of Bari To Offer Lp-44 – A Novel, Selective 5-Ht7 Agonist
December 18, 2012 Business News(PRLEAP.COM) Abcam today announced signing a licence with the University of Bari to offer LP-44 – a novel, selective 5-HT7 agonist. This life sciences tool, new to the Abcam Biochemicals range, is set to aid neuronal research into various neuropsychiatric diseases.
5-HT7 receptors are present in various regions of the central nervous system indicating a potential for therapeutic intervention in various neuropsychiatric diseases. Expression in brain regions (suprachiasmatic nuclei) involved in circadian rhythms may point to an involvement in sleep disorders. Many promising 5-HT7 compounds have failed to meet expectations of potency, selectivity and metabolic stability and few agonists have been reported. LP-44 and LP-12, identified from chemical screens, show high selectivity and potency for 5-HT7, at nanomolar concentrations in in vitro binding assays.
Steve Roome, Abcam Biochemical's General Manager explains, "It is very exciting to finally see a selective 5-HT7 receptor agonist with the potential to enhance behaviour and circadian rhythm. The addition of these new selective tools really enhances the power of serotonin research in the field."
LP-44 - Shows >200 and >1000-fold selectivity for 5-HT7 over 5-HT1A and 5-HT2A receptors (Ki values are 0.22, 52.7 and 326 nM respectively). Supresses REM sleep.
LP-12 - 5-HT7 agonist. Selective over D2, 5-HT1A and 5-HT2A receptors (Ki values are 0.13, 224, 60.9 and >1000 nM respectively). Shows pro-nociceptive effect.
