产品介绍
W-7 hydrochloride 是一种选择性的钙调蛋白 (calmodulin) 拮抗剂。W-7 hydrochloride 抑制Ca2+-钙调蛋白依赖性磷酸二酯酶 (phosphodiesterase) 和肌球蛋白轻链激酶 (myosin light chain kinase),IC50值分别为 28 μM 和 51 μM。W-7 hydrochloride 可诱导细胞凋亡 (apoptosis),并具有抗癌活性。
生物活性

W-7 hydrochloride is a selectivecalmodulinantagonist. W-7 hydrochloride inhibits theCa2+-calmodulin-dependentphosphodiesteraseandmyosinlight chain kinasewithIC50values of 28 μM and 51 μM, respectively[1][2]. W-7 hydrochloride inducesapoptosisand has antitumor activity[3].

IC50& Target

IC50: 28 μM (Phosphodiesterase) and 51 μM (Myosin light chain kinase)[1]

体外研究
(In Vitro)

W-7 is distributed mainly in the cytoplasm, and inhibits proliferation of Chinese hamster ovary K1 (CHO-K1) cells. W-7 selectively blocks the phase of the cell cycle (G1/S boundary phase) in a manner. 25 μM W-7 arrests the growth of the cells at the G1/S boundary phase of the cell cycle[1].
W-7 (100 μM) exhibits a similar extent of antagonism between the contractile responses to carbachol and KCl. The increase in myosin light chain (P-LC) phosphate content in response to 1-min stimulation with 10 μM carbachol is inhibited by W-7. W-7 antagonizes the smooth muscle contraction through the inhibition of the initial increase in the P-LC phosphorylation[2].
Treatment with W-7 results in the dose-dependent inhibition of cell proliferation in various human multiple myeloma cell lines. W-7 induces G1 phase cell cycle arrest by downregulating cyclins and upregulating p21cip1. W-7 induces apoptosis via caspase activation; this occurred partly through the elevation of intracellular calcium levels and mitochondrial membrane potential depolarization and through inhibition of the STAT3 phosphorylation and subsequent downregulation of Mcl-1 protein[3].
W-7 competitively inhibits Ca2+/calmodulin-dependent phosphodiesterase with a Kivalue of 300 μM[4].
