包装规格:100mg in glass bottle
产品简介:一种细胞内Ca2+调节剂,通过反向模式抑制Na+/Ca2+交换作用。
溶解性:DMSO :4.81 mg/mL (18.77 mM; 超声助溶 (<60 ℃);酸性条件溶解 (HCL 调节,pH=3)
储备液保存:-80°C, 6 months -20°C, 1 month (protect from light)
靶点:Na+/Ca2+ exchanger
体外研究:Caldaret (MCC-135) is demonstrated to restore Ca2+-ATPase activity of the sarcoplasmic reticulum (SR) isolated from the myocardium acutely exposed to ischemia and reperfusion in vitro.
体内研究:Caldaret, an intracellular Ca2+ handling modulator, limits infarct size of reperfused canine heart. The cardioprotective effect of Caldaret, a novel intracellular Ca2+ handling modulator that acts through reverse-mode Na+/Ca2+ exchanger inhibition and potential sarcoplasmic reticulum (SR) Ca2+ uptake enhancement, against reperfusion injury is investigated. Intravenously infused Caldaret (3 or 30 microg/kg per hour) for 30 min at left circumflex (LCX)-reperfusion markedly reduces infarct size (by 51.3% or 71.9%, respectively). The amelioration of intracellular Ca2+ handling dysfunction achieved by Caldaret leads to cardioprotective effects against reperfusion injury following prolonged ischemia. Caldaret (MCC-135) is a new potent compound with beneficial effects in heart failure. In diabetic rats, Caldaret decreases TR80 significantly without significant effect on developed tension (DT). Caldaret has minimal effects on SR Ca2+ uptake in normal rats, that is observed as increased SR Ca2+ uptake at uptake time of 20 and 30 s at the highest concentration of 10 μM. In diabetic rats, Caldaret increases SR Ca2+ uptake all over the range of uptake time. Both initial rate of SR Ca2+ uptake and the amount of Ca2+ accumulated in the SR with longer uptake time are increased by Caldaret.
