Kuwanon H
Based on 1 Customer Validation
Kuwanon H is a selective non-peptide bombesin receptor antagonist and platelet activation inhibitor. Kuwanon H also acts as a specific antagonist of GRP-preferring receptors, with a Ki value of 290 nM for mouse GRP-R and 6500 nM for rat NMB-R. Kuwanon H inhibits the phosphorylation of AKT, mTOR, ERK, cPLA2 and p38, and upregulates TRIB3. It induces endoplasmic reticulum stress, apoptosis and autophagosome formation. Kuwanon H blocks calcium mobilization, mitogenic signaling, DNA synthesis, dense granule secretion, thromboxane A2 generation and integrin αIIb/β3 activity. It inhibits collagen-induced platelet aggregation and fibronectin adhesion, and delays clot retraction. Kuwanon H inhibits melanoma cell growth in vitro and in vivo, and enhances the sensitivity of melanoma cells to CDDP. It can be used in research related to melanoma, small cell lung cancer and thrombosis.

In Vitro
Kuwanon H (75-200 μM; 5 min) inhibits collagen-induced intracellular calcium mobilization in platelets by regulating InsP3R and ERK phosphorylation[3].
Kuwanon H (75-200 μM; 2 min pre-incubation, 7 min aggregation monitoring) inhibits collagen-induced secretion of 5-hydroxytryptamine and ATP from dense granules in platelets[3].
Kuwanon H (75-200 μM; 2 min pre-incubation, 7 min aggregation monitoring) inhibits collagen-induced TXA2 production in platelets by reducing the phosphorylation levels of cPLA2 and p38[3].
Kuwanon H (75-200 μM; 2 min incubation, 20 min adhesion incubation) inhibits Collagen-induced fibronectin adhesion in human platelets[3].
Kuwanon H (75-200 μM; 1 min incubation, 25 min clot retraction monitoring) inhibits integrin αIIb/β3 activity by regulating the phosphorylation of Akt and VASP, thereby delaying thrombin-induced fibrin clot retraction in human platelet-rich plasma (PRP)[3].
Kuwanon H inhibits the binding of [125I]bombesin to NMB-preferring receptors in rat esophageal membranes, with a Ki value of 6500 nM, indicating that its potency against NMB-Rs is 22.4-fold lower than that against GRP-Rs[2].
Kuwanon H (500 nM; administered 1 min prior to agonist stimulation) reduces the bradykinin-induced elevation of cytosolic free calcium by 60% in mouse Swiss 3T3 fibroblasts, without altering basal calcium levels or cellular responses to endothelin-1 and bradykinin[2].
