Quantitation of the next-generation imipridone ONC206 in human plasma by a simple and sensitive UPLC-MS/MS assay for clinical pharmacokinetic application.

ONC206 is an imipridone derivative that is being developed clinically as a single agent given orally in a first-in-human trial (NCT04541082). This ongoing clinical trial requires pharmacokinetic analysis of ONC206 to fully characterize its pharmacologic profile. There is currently no published bioanalytical method for ONC206 quantitation.

Psychedelic-inspired drug discovery using an engineered biosensor.

Ligands can induce G protein-coupled receptors (GPCRs) to adopt a myriad of conformations, many of which play critical roles in determining the activation of specific signaling cascades associated with distinct functional and behavioral consequences. For example, the 5-hydroxytryptamine 2A receptor (5-HT2AR) is the target of classic hallucinogens, atypical antipsychotics, and psychoplastogens. However, currently available methods are inadequate for directly assessing 5-HT2AR conformation both in vitro and in vivo.

Identification of Psychoplastogenic ,-Dimethylaminoisotryptamine (isoDMT) Analogues through Structure-Activity Relationship Studies.

Ketamine, ,-dimethyltryptamine (DMT), and other psychoplastogens possess enormous potential as neurotherapeutics due to their ability to potently promote neuronal growth. Here, we report the first-ever structure-activity relationship study with the explicit goal of identifying novel psychoplastogens. We have discovered several key features of the psychoplastogenic pharmacophore and used this information to develop ,-dimethylaminoisotryptamine (isoDMT) psychoplastogens that are easier to synthesize, have improved physicochemical properties, and possess reduced hallucinogenic potential as compared to their DMT counterparts.
