    • A crystal structure of compound 19 was obtained, which allowed assignment of the absolute stereochemistry of this compound. The stereochemistry of other compounds was assigned by analogy using characteristic NMR shifts. The chemical shifts for the protons on the methylene group adjacent to the pyrazole ring were particularly diagnostic. The signals for these protons were generally observed close to 2 ppm for the diastereomers with an R configuration at the hydroxyl center and close to 3 ppm for compounds with an S configuration at the hydroxyl center.

    • Preliminary experiments showed that dissociation in mouse cell lines generally correlated well with dissociation in human cell lines; rat cell lines did not correlate as well.

    • The barrier to rotation was calculated by rotating the pendant aromatic 420° about the dihedral torsion already described and determining the energy of the rotamer at each 10° increment using MMFF with a distance-dependent dielectric of 2r.

    • Incubation of compound 18 (10 μM) with mouse liver microsomes (1 mg/mL) in the presence of NADPH showed no parent and primarily a metabolite of MW = parent + 32 after 30 min. In contrast, compound 19 showed primarily the parent compound and very little metabolism under the same conditions.
