产品介绍
Diazoxide (Sch-6783) 是一种 ATP 敏感性钾通道激活剂,具有治疗高胰岛素血症的潜力。

Cell experiment:

Diazoxide is dissolved in DMSO to prepare 50 mM stock solution. NSC-34 cells are allowed to differentiate for 8 weeks under reduced serum conditions and then seeded in 24-well plates. Glutamate is dissolved in culture medium and added to cultures at concentration of 10 μM for 24 h. Cell treatment with 100 μM diazoxide starts 2 h before glutamate exposure. Cell viability is measured by the MTT assay[2].

Animal experiment:

Rats: Adult male Sprague-Dawley rats with induced cerebral ischemia (n=10 per group) receive an intraperitoneal injection of 0.1% DMSO (1 mL; vehicle group), diazoxide (10 mg/kg; DZ group), or diazoxide (10 mg/kg) plus 5-hydroxydecanoate (5 mg/kg; DZ + 5-HD group) 30 min after CPR. The control group (sham group, n=5) undergoes sham operation, without cardiac arrest. Mitochondrial respiratory control rate (RCR) is determined. Brain cell apoptosis is assessed using TUNEL staining. Expression of Bcl-2, Bax, and protein kinase C epsilon (PKCε) in the cerebral cortex is determined by Western blotting and immunohistochemistry[3]. Mouse: Diazoxide is prepared by diluting a 100 mM stock solution in 10% polyethoxylated castor oil in PBS. In C57BL/6 wild-type and Kir6.2(–/–) mice, a 5 μL drop of 5 mM diazoxide is topically administered to one eye of each mouse while the fellow control eye received vehicle (DMSO and 10% polyethoxylated castor oil in the same proportion as the treated eye). IOP is measured daily at 1 hour, 4 hours, and 23 hours following treatment. Treatment with diazoxide and vehicle is continued daily for 14 consecutive days[4].

产品描述

3-Methyl-7-chloro-1,2,4-benzothiadiazine 1,1-dioxide (Sch-6783) is an ATP-sensitive potassium channel activator, can be used to treat hyperinsulinism.
3-Methyl-7-chloro-1,2,4-benzothiadiazine 1,1-dioxide (Sch-6783) has a number of physiological effects, including lowering the blood pressure and rectifying hypoglycemia. Diazoxide has powerful protective properties against cardiac ischemia[1].
3-Methyl-7-chloro-1,2,4-benzothiadiazine 1,1-dioxide (Sch-6783) could protect NSC-34 neurons against the main sources of neurodegenerative damage. Diazoxide increases Nrf2 nuclear translocation in NSC-34 motoneurons and prevents endogenous oxidative damage[2].
3-Methyl-7-chloro-1,2,4-benzothiadiazine 1,1-dioxide (Sch-6783) attenuates postresuscitation brain injury, protects mitochondrial function, inhibits brain cell apoptosis, and activates the PKC pathway by opening mitoKATP channels[3]. Treatment with 3-Methyl-7-chloro-1,2,4-benzothiadiazine 1,1-dioxide (Sch-6783) in wild-type mice decreases intraocular pressure (IOP) by 21.5±3.2% with an absolute IOP reduction of 3.9 ± 0.6 mm Hg[4].
