In Vivo Data

Off-Target Selectivity Assesments

Potency assay (off target): Broad profiling screens performed at Eurofins and PDSP
Probe Selectivity in Vitro:
25CN-NBOH also displayed appreciable binding affinity at 5-HT6 (Ki value of 310 nM), dopamine D4 (Ki value 2.9 μM), α2A, α2B, and α2C adrenergic (Ki values of 1.2–2.9 μM), H1 histamine (Ki value of 2.1 μM), κ opioid (Ki value of 4.2 μM), and sigma-1 and -2 (Ki values of 120–280 nM) receptors
Probe Selectivity in Vitro:
Tested at a wide range of kinases and other enzymes in enzymatic assays, displaying no significant activity at 10 μM. In addition, 25CN-NBOH inhibited hERG with an IC50 value of 2.7 µM.

SERP Comments:

Need to be aware compound is active on multiple targets - HTR2A, HTR2B, and HTR2C - when drawing biological conclusions from studies carried out with this compound.
Important to measure drug concentrations in any efficacy studies to put other pharmacology into context:  sigma-1 (Ki = 284 nM), α2C (Ki = 543 nM), 5-HT6 (Ki = 573 nM), sigma-2 (Ki = 575 nM), α2A (Ki = 803 nM)
