| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

| About Packaging | 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial. 2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial. 3. Try to avoid loss or contamination during the experiment. |

Non-peptide bombesin receptor antagonists, kuwanon G and H, isolated from mulberry.[Pubmed:7646517]
Biochem Biophys Res Commun. 1995 Aug 15;213(2):594-9.
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. Thus, Kuwanon H, and possibly kuwanon G also, are specific antagonists for the GRP-preferring receptor and can be useful for studying the physiological and pathological role of GRP.
Kuwanon H is a flavonoid isolated from Morus bombycis, which acts as a potent non-peptide bombesin receptor antagonist. Kuwanon H selectively inhibits binding of gastrin releasing peptide CRP to GRP-preferring recepotr, with a Ki value of 290 nM in cells.
