Replacement of the 1,3,4-oxadiazole with other heterocycles or replacement of the sulfoxide group of 1,3,4-oxadiazole with a carbonyl or a sulfone resulted in compounds that were inactive in the HUVEC assay. 7.

    • 8. (a) The ELISA for the determination of presence's of ELAM-1 and VCAM-1 is as follows: 96-well plates were coated with 2% gelatin (1 h). The excess gelatin was aspirated from the wells. HUVE cells were seeded at 20,000 cells/well in a 200 μL volume. The test compounds were dissolved in DMSO at a stock concentration of 50 mM. When the monolayer reached confluence (24-28h after seeding), the test compounds were added to the wells at a final concentrations of 30 μM, 10 μM, 3 μM, and 1 μM. Each compound was added in duplicate. The plates were incubated for 4 h at 37 °C. Then, IL-1 β was added at a final concentration of 2 ng/mL and the plates were incubated for 4 h at 37 °C. The supernatant was removed from the plates by decanting and the wells were washed 3X with 1% BSA-Dulbecco's PBS. Primary antibody [7A9 for ELAM-1 (Otsuka Pharm.) and 2G7 for VCAM-1 (Otsuka Pharm.)] at a concentration of 2.5 μg/mL in a 50 μL volume was added to each well. The plates were incubated at 4 °C for 45 min to 1 h. The wells were washed 3X with 1% BSA Dulbecco's PBS. Secondary antibody (F (Ab')2 fragment biotinylated goat antimouse IgG-IgM (Jackson ImmunoResearch) at 50 μL/well at a final dilution of 1:1,000 was added and incubated for 45 min to 1 h at 4 °C. The wells were washed 3X with 1% BSA-Dulbecco's PBS. Streptavidin-peroxidase (Sigma) at 50 μL/well with a final dilution of 1:30,000 was added to each well and the plates were incubated at 4°C for 30 min. Substrate solution (OPD tablets, citric acid buffer and hydrogen peroxide solution) was added at a concentration of 100 μL/well. The plates were incubated for 15 min at room temperature on plate shaker and the reaction was stopped with 12.5% sulfuric acid. Plates were read for absorbance at 492 nm and the reading for the duplicate averaged.

    • note
    • 11. A selective alkylation (nucleophilic attack on the C-2 of the 1,3,4-oxadiazole) of a receptor or an enzyme in the signal transduction pathway is suspected. This may explain the decrease in activity for those compounds that appear to be more stable to attack at C-2 of the oxadiazole.

This was followed immediately by an ID 25 μL injection of anti-BSA (0.5 mg/mL solution) along with the test compound or vehicle on a predetermined site on the backside of the mice. Four hours post injection, the animals were sacrificed and the skins removed and assayed for myeloperoxidase (MPO) activity as a measure of neutrophils, according to the procedure of Mulligan, M. S.; Ward, P. A. J. Imm. 1992, 149, 331. Each compound was tested on a group of seven mice.
