Author is Schuster, Daniela; Laggner, Christian; Steindl, Theodora M.; Langer, Thierry.

In today’s drug discovery process, the very early consideration of ADME properties is aimed at a reduction of drug candidate drop out rate in later development stages. A part from in vitro testing, in silico methods are evaluated as complementary screening tools for compounds with unfavorable ADME attributes. Especially members of the cytochrome P 450 (P 450) enzyme superfamily. e.g. P 450 1A2, P 450 2C9, P 450 2C19, P 450 2D6, and P 450 3A4, contribute to xenobiotic metabolism, and compound interaction with one of these enzymes is therefore critically evaluated. Pharmacophore models are widely used to identify common features amongst ligands for any target. In this study, both structure-based and ligand-based models for prominent drug-metabolizing members of the P 450 family were generated employing the software packages LigandScout and Catalyst. Essential chem. ligand features for substrate and inhibitor activity for all five P 450 enzymes investigated were determined and analyzed. Finally, a collection of 11 pharmacophores for substrates and inhibitors was evaluated as an in silico P 450 profiling tool that could be used for early ADME estimation of new chem. entities.

A new and effective method for the preparation of (S)-3-amino-1,2-propanediol was established starting from (R)-epichlorohydrin. The synthetic approach involves the reaction of (R)-epichlorohydrin with acetone catalyzed by BF3·OEt2 to give (R)-4-(chloromethyl)-2,2-dimethyl-1,3-dioxolane. Subsequent replacement of the Cl with NH2 group by azidation followed by reduction gave ((S)-2,2-dimethyl-1,3-dioxolan-4-yl)methanamine, which was converted into (S)-3-aminopropane-1,2-diol·HCl by acetal deprotection with MeOH·HCl.

Interest in replacing palladium catalysts with base metals resulted in the development of a 24-reaction screening platform for identifying nickel-catalyzed Suzuki-Miyaura reaction conditions. This method was designed to be directly applicable to process scale-up by employing homogeneous reaction conditions alongside stable and inexpensive nickel(II) precatalysts and has proven to be broadly suitable for complex heterocyclic substrates relevant to bioactive mols. These advances were enabled by the key discovery that a methanol additive greatly improves the reaction performance and enables the use of organic-soluble amine bases. The screening platform and scale-up workflow were applied to a representative cross-coupling using the antipsychotic perphenazine and enabled the rapid development of a gram-scale synthesis that highlighted the utility of this method and the advantages of nickel catalysis for metal remediation.
