Activity Assays: Measurement of forskolin stimulated inhibition of cAMP was performed via time-resolved fluorescence resonance energy transfer (TR-FRET) LANCE assay (AD0262, PerkinElmer Life Science, Inc., Boston Mass.). Recombinant Chinese hamster ovary (CHO-K1) cells expressing human somatostatin SSTR4 cells (ES-524-CF, PerkinElmer Life Science, Inc., Boston Mass.) were thawed (37° C.), resuspended in 10 mL Hanks' balanced salt solution no phenol red (HBSS, Invitrogen, Carlsbad Calif.), and then centrifuged (150×g, 5 minutes). Cellular pellet resuspended in stimulation buffer containing HBSS 1×, HEPES 5 mM, Protease free BSA 0.1% (PerkinElmer), and 3-Isobutyl-1-methylxanthine 0.5 mM (pH 7.4) and seeded in 96-well plates at 4000 cells/well. LANCE cAMP assay was performed per manufacture instruction with assessment of respective compound, somatostatin-28 (Sigma-Aldrich Co., St. Louis, Mo.) as control agonist, against 5 μM forskolin, performed in triplicate across concentration curve. Fluorescence signal was measured at 20 hours (excitation 340 nm and emission 665 nm, 400-μs delay) via TR-FRET (FLUOSTAR Omega-F, BMG Labtech, Inc., Cary, N.C.). Data was calculated via GraphPad PRISM-5 software.
