The remarkable effects exhibited by classical psychedelics in recent clinical trials have spawned considerable interest in 5-HT2A receptor (5-HT2AR) activation as a treatment strategy for several psychiatric/cognitive disorders. In this study we have continued our development of 25CN-NBOH, one of the most 5-HT2AR-selective agonists reported to date, as a pharmacological tool for exploration of 5-HT2AR expression and functions. The importance of the 2? and 3? positions in 25CN-NBOH as structural hotspots for its 5-HT2AR activity was investigated by synthesis and pharmacological characterization of six novel analogs at 5-HT2AR and 5-HT2CR in binding and functional assays. While the 5-HT2AR activity of 25CN-NBOH was retained in 3?-methyl, 2?,3?-chroman, 2?,3?-dihydrofuran and 2?,3?-furan analogs, the 3?-methoxy and 3?-ethyl analogs displayed substantially lower binding affinities and agonist potencies than 25CN-NBOH. Interestingly, the 2?,3?-substitution pattern was also a key determinant of agonist efficacy, as all six analogs exhibited low-efficacy partial agonism or defacto antagonism at the 5-HT2AR in the functional assays. Systemic administration of 25CN-NBOH and its close structural analog 25CN-NBMD induced robust head-twitch response in mice, a well-established behavioural effect of 5-HT2AR activation in vivo, and 25CN-NBOH mediated robust reductions in the activity of mice in an anxiety-related marble burying assay, which supports the proposed beneficial effects of 5-HT2AR activation on disorders characterized by cognitive rigidity. Finally, tritiated 25CN-NBOH exhibited high 5-HT2AR binding affinity (KD ~1 nM) and selectivity against 5-HT2BR and 5-HT2CR in equilibrium and kinetic binding studies of the recombinant receptors, and in concordance [3H]25CN-NBOH displayed substantial specific, ketanserin-sensitive binding to cortex and small levels of binding to choroid plexus in rat brain slices in autoradiography studies. In conclusion, this work delineates the subtle molecular determinants of the 5-HT2AR activity in 25CN-NBOH, substantiates the potential in this compound and its analogs as tools for in vivo studies of 5-HT2AR, and introduces a novel selective agonist radioligand as another potentially valuable tool for future explorations of this receptor.
We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 196799-45-8, and how the biochemistry of the body works.SDS of cas: 196799-45-8
