SW-106

SW-106 (incubated for 3 h) competes with the PPR probe peptide DPC-AJ1951 for binding to PPR in B28 cells, with an IC₅₀ of 0.99 μM, and does not act as an agonist to induce cAMP production in these cells^[1].
SW-106 acts as a competitive antagonist of PPR-mediated cAMP production in B28, SaOS-2 and UMR106 cells, with an IC₅₀ of 5.78 μM against DPC-AJ1951 and 68 μM against PTH-(1-34) in B28 cells^[1].
SW-106 exhibits more selective activity toward PPR than toward the GLP-1 receptor and most tested class A GPCRs, showing only weak binding to a small subset of class A receptors at concentrations ≥10 μM^[1].
SW-106 (3 × 10^-5 M; up to 90 min) exhibits weak intrinsic agonist activity toward wild-type hPTHR1 expressed in GS-22A cells, increasing cAMP levels by ~5-fold at a concentration of 3 × 10^-5 M^[2].
SW-106 (1 × 10^-6 M-1 × 10^-5 M; up to 30 min) effectively inhibits the cAMP signaling pathway mediated by the tethered PTH (1-9) sequence on PTHR-Tether (1-9) expressed in GS-22A cells^[2].
