    • 2 at 37 °C, prior to incubation with test compounds. Dilutions of test compounds in DMSO (0.1% DMSO final concentration in assay) are added to the cells. Following a 60-min incubation LPS is added (final LPS concentration 10 μg/mL). Following a 60 min incubation cells are harvested and lysed for the measurement of total and phosphorylated Hsp27 (pHsp27). Total Hsp27 and pHsp27 are quantified using the Multi-Spot assay from Meso Scale according to protocol.

    • 2 at 37 °C in humidified atmosphere, culture medium is collected for the measurement of TNFα. The amount of TNFα in the culture medium is quantified by ELISA using HuTNFα assay from Cytoset according to protocol.

    • Separation of enantiomers was effected at the chloropyrimidine stage on a Chiralpack AD-H column (20 x 250 mm, particle size 5 μm), eluting with heptane/IPA (80/20 v/v). Stereoisomer 1 eluted at 15.8 min, and stereoisomer 2 at 27.8 min. Ee's were >99% as determined with analytical chiral chromatography.

    • -1 resolution. Calculations: A model of the (S)-configuration was built and a conformational search was carried out with Hyperchem (Hypercube, Inc., Gainesville, FL, USA) for the entire structure at the molecular mechanics level. Geometry optimization, frequency, IR and VCD intensity calculations of 47 conformers, which resulted from the conformational search, were carried out at the DFT level (B3LYP functional/6-31G(d) basis set) with GAUSSIAN 09 (Gaussian Inc., Wallingford, CT). The four lowest-energy conformers were used for calculating the averaged VCD and IR spectra. The configurations were assigned by spectral comparison of experimental and calculated spectra.
