KW-5617 (zaldaride maleate), 1,3-dihydro-1-[1-[(4-methyl-4H,6H-pyrrolo[1,2-a][4,1]-benzoxazepin -4-yl)methyl]-4-piperidinyl]-2H-benzimidazol-2-one maleate, is a selective calmodulin inhibitor. We studied the effects of KW-5617 on secretory diarrhea and gastrointestinal propulsion in rats, as compared with those of loperamide, a conventional anti-diarrheal drug. Diarrhea was induced in rats

The signal transduction that mediates CCK-induced contraction of gallbladder muscle was investigated in the cat. Contraction was measured by scanning micrometry in single muscle cells isolated enzymatically with collagenase. Production of D-myo-inositol 1,4, 5-trisphosphate (IP3) and sn-1,2-diacylglycerol (DAG) was quantitated

The estrogen receptor mediates breast cell proliferation and is the principal target for chemotherapy of breast carcinoma. Previous studies have demonstrated that the estrogen receptor binds to calmodulin-Sepharose in vitro. However, the association of endogenous calmodulin with endogenous estrogen receptors
