Introduction of an acetate (R = Ac) led to the most frequent active compounds, whereas bulky carboxylic residues such as benzoic, pivalic, or iso-pentanoic acids as the R group induced lower activity (Scheme 19).
The most frequent categories of compounds presented are secretagogues and anti-inflammatory drugs.
The second most frequent reason for compounds not progressing beyond Phase I trials is that the agent was superseded by an improved analogue or derivative.
The most frequent types of these compound groups in mammalian tissues are alpha-tocopherol and ubiquinone-10 in humans.
Among these compounds the most frequent copper phosphate found as a corrosion product is libethenite (Cu2(often4) often associated with cremation sites.
The most frequent assay targets for these compounds were CYPs (CYP2C19 and CYP1A2) and TSPO (human and rat).

The di-valent chlorine atom showcased in the eighth most frequent environment exclusively found in Compound was deposited without charge and is modified to erroneously standardize to this atom type.
The top-10 most frequent environments (r = 3) in Compound are almost identical to those in Substance.
Similarly to the protein-organic compound complexes, the most frequent hydrogen bond incorporates the NH- group of a residue that serves as the donor and the oxygen atom of a ligand.
