Analyzing Oxygen Atom Distribution in FDA‐Approved Drugs to Enhance Drug Discovery Strategies

Chemical Biology and Drug Design

In general, existence of sp 3 -O slightly outperforms sp 2 -O, which is associated with balancing various factors such as flexibility, solubility, stability, and pharmacokinetics, in addition to activity and selectivity. In approved drugs, majority of oxygen atoms are present within 4 from the COM of the molecule.

Evaluating the Abuse Potential of Lenabasum, a Selective CB2 Cannabinoid Receptor Agonist [Behavioral Pharmacology]

ASPET

Secondary VAS and pharmacokinetic (PK) endpoints and adverse events were assessed. Drug Liking and all other VAS outcomes were greatest for nabilone 3mg and 6mg, which is a currently FDA-approved medication. Three doses of lenabasum (20, 60, and 120mg) were compared to placebo, and nabilone (3 and 6mg).
