Comment: Navacaprant (NMRA-140; formerly BTRX-335140, a.k.a. CYM-53093) is a selective κ opioid receptor antagonist [1]. It had favourable drug-like properties in preclinical models, and was proposed as a potential therapeutic for migraine [2], stress-related mood disorders (including depression), anxiety, and drug abuse. Neumora Therapeutics acquired BTRX-335140 in their buyout of Blackthorn Therapeutics. The chemical structure for NMRA-140 matches that for the INN navacaprant.
![]() Ligand Activity Visualisation ChartsThese are box plot that provide a unique visualisation, summarising all the activity data for a ligand taken from ChEMBL and GtoPdb across multiple targets and species. Click on a plot to see the median, interquartile range, low and high data points. A value of zero indicates that no data are available. A separate chart is created for each target, and where possible the algorithm tries to merge ChEMBL and GtoPdb targets by matching them on name and UniProt accession, for each available species. However, please note that inconsistency in naming of targets may lead to data for the same target being reported across multiple charts. ✖ |

Bioactivity Comments |
In a screening panel of >500 off-targets (ion channels, kinases, GPCRs, other receptors and transporters) no hits identified with IC50 values <1 μM BTRX-335140, minimal inhibition of a range of CYP450 enzymes was detected, and the IC50 for hERG inhibition was 1 μM in a patch clamp assay [1]. |
