Chowdhury, Sultan,Georghiou, Paris E.
, p. 6808 - 6811 (2002)
The synthesis of a new endo-calix[4]naphthalene is described. The reaction sequence involves the cyclocondensation of a key bisnaphthylmethane intermediate (8) with formaldehyde. This key intermediate (8) is formed using a modified Suzuki-Miyaura Pd-catalyzed crosscoupling reaction between bromomethylnaphthyl (6) and naphthylboronic acid (7), both of which can be derived from 2-hydroxynaphthoic acid.

An anthracene derivative represented by the following formula (1): wherein in the formula (1), L1 is selected from a single bond and a linking group, and the linking group is selected from a divalent arylene group, a divalent heterocyclic group, and a group formed by linking of 2 to 4 of divalent arylene groups and/or divalent heterocyclic groups. Ar1 is selected from the following formulas (2) and (3). In the formulas (2) and (3), X is selected from an oxygen atom and a sulfur atom. In the formula (2), any one of R11 to R14 is used for bonding to L1. In the formula (3), any one of R21 to R24 is used for bonding to L1. Ar2 is selected from a substituted or unsubstituted aryl group including 6 to 50 ring carbon atoms and a substituted or unsubstituted heterocyclic group including 5 to 50 ring atoms.

Pharmacophore modeling of a series of aldosterone synthase (CYP11B2) inhibitors triggered the design of compounds 11 and 12 by extending a previously established naphthalene molecular scaffold (e.g., present in molecules 1 and 2) via introduction of a phenyl or benzyl residue in 3-position. These additional aromatic moieties have been hypothesized to fit into the newly identified hydrophobic pharmacophore feature HY3. Subsequent docking studies in our refined CYP11B2 protein model have been performed prior to synthesis to estimate the inhibitory properties of the proposed molecules. While phenyl-substituted compound 11 (IC50 > 500 nM) did not dock under the given pharmacophore constraint (i.e., the Fe(heme)-N(ligand) interaction), benzyl-substituted compound 12 (IC50 = 154 nM) was found to exploit a previously unexplored subpocket of the inhibitor binding site. By structural optimization based on the pharmacophore hypothesis, 25 novel compounds were synthesized, among them highly potent CYP11B2 inhibitors (e.g., 17, IC 50 = 2.7 nM) with pronounced selectivity toward the most important steroidogenic and hepatic CYP enzymes.
