We evaluated the pharmacological profile of ritobegron [KUC-7483; (-)-ethyl 2-[4-(2-{[(1S,2R)-2-hydroxy-2-(4-hydroxyphenyl)-1-methylethyl]amino}ethyl)-2,5-dimethylphenyloxy]acetate monohydrochloride] and its effects on the bladder in cynomolgus monkeys by in vitro and in vivo experiments. In vitro, ritobegron decreased the resting tension of the isolated(More)
We performed in vitro and in vivo experiments to evaluate the pharmacological profile of ritobegron and its effects on the bladder in rats. β3-AR selectivity was assessed using CHO cells expressing various subtypes of the human β-adrenoceptor (AR). Effects on isolated organs were evaluated using the organ-bath method. Effects on intravesical pressure, heart(More)
Restenosis after percutaneous transluminal coronary angioplasty (PTCA) occurs due to vascular smooth muscle cell proliferation and migration. Recently, tranilast, an anti-allergic drug, has been used for the prevention of restenosis after PTCA. To determine the molecular mechanism involved, the effect of tranilast on the proliferation of human coronary(More)
The low-affinity sodium glucose cotransporter (SGLT2) is responsible for most of the glucose reabsorption in the kidney and has been highlighted as a novel therapeutic target for the treatment of diabetes. We discovered sergliflozin etabonate, a novel selective SGLT2 inhibitor, and found that selective inhibition of SGLT2 increased urinary glucose excretion(More)
In this study, we used a coactivator-dependent receptor-ligand interaction assay (CARLA), which is a semifunctional in vitro assay, to determine whether hypolipidemic drugs are ligands for the three peroxisome proliferator-activated receptor isotypes (PPARalpha, delta, and gamma). We also evaluated the transcriptional activities of the three PPAR isotypes(More)
AIM The aim of this study was to investigate the preventive actions of bezafibrate against non-alcoholic steatohepatitis (NASH), the activation of hepatic stellate cells (HSC), and fibrogenesis by using a model of NASH and an in vitro model. METHODS Male KK-A(y)/TaJcl (KK-A(y)) mice were fed a methionine and choline-deficient (MCD) diet or a MCD diet(More)
Mitiglinide (KAD-1229), a new anti-diabetic drug, is thought to stimulate insulin secretion by closing the ATP-sensitive K+ (K(ATP)) channels in pancreatic beta-cells. However, its selectivity for the various K(ATP) channels is not known. In this study, we examined the effects of mitiglinide on various cloned K(ATP) channels (Kir6.2/SUR1, Kir6.2/SUR2A, and(More)
MAGP-36 was discovered in porcine aorta in 1989 and is thought to be one of the microfibril-associated proteins. MAGP-36 has been localized on the surface of elastic fibers or laminae in immunohistochemical studies. However, its functional role in the aorta is obscure. Herein, we report on the binding activity of MAGP-36 to components of the aortic wall and(More)
We investigated the direct effects of various bisphosphonates on osteoblasts. At 10(-5) M, clodronate increased alkaline phosphatase activity in cultured MC3T3-E1 (osteoblast-like line) and ST2 (pluripotent mesenchymal line) cells. Etidronate significantly increased alkaline phosphatase activity at 10(-5) M only in MC3T3-E1 cells. These effects were due to(More)
This study was performed to characterize the α1-adrenoceptor subtypes in mouse ureters as regards gene expressions and contractile functions. The mRNAs for these subtypes were quantified by the real-time quantitative reverse transcription polymerase chain reaction. In a functional study, α1-adrenoceptor antagonists were evaluated against the(More)
