| Description | Kuwanon H is a specific antagonist for the gastrin-releasing peptide (GRP) -preferring receptor with Ki values of 290 nM and can be useful for studying the physiological and pathological role of GRP. Kuwanon H is a potent non-peptide bombesin receptor antagonist. |

| In vitro | Kuwanon G and H, isolated from the methanol extract of Morus bombycis, inhibited specific binding of [125I]gastrin-releasing peptide (GRP) to GRP-preferring receptors in murine Swiss 3T3 fibroblasts with Ki values of 470 and 290 nM, respectively. Kuwanon H was one order of magnitude less potent for inhibiting [125I]bombesin binding to neuromedin B (NMB)-preferring receptors in rat esophagus membranes. This compound antagonized bombesin-induced increases in the cytosolic free calcium concentration and GRP-induced DNA synthesis in Swiss 3T3 cells. |
