生物活性

GP531 is a potent, second-generation adenosine regulating agent, is pharmacologically silent under basal conditions but increases localized endogenous adenosine during ischemia.

IC50 & Target

Adenosine Receptor[1]

体内研究
(In Vivo)

Low-dose GP531 reduces infarct size by 34% compared with vehicle and reduces the extent of the anatomic no-reflow zone by 31% compared with vehicle. Infarct size and zone of no-reflow in the high dose are reduced by 22% and 16%, respectively. GP531 does not affect hemodynamics or blood flow. GP531 is effective at the lower dose in reducing the severity of ischemic/reperfusion injury, without inducing the adverse hemodynamic effects associated with adenosine administration such as bradycardia and hypotension[1]. GP531 infusion has no effect on heart rate or mean aortic pressure but significantly decreases left ventricular end-diastolic pressure, end-diastolic volume, end-systolic volume and end-diastolic wall stress. GP531 significantly increases left ventricular EF, deceleration time of early mitral inflow velocity and the slope of end-systolic PVR without increasing MVO2[2].

请根据您的 实验动物和给药方式 选择适当的溶解方案。

以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液,再依次添加助溶剂:
——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议您现用现配,当天使用
以下溶剂前显示的百分比是指该溶剂在您配制终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶

  • 方案 一

    请依序添加每种溶剂: 10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.08 mg/mL (5.99 mM); 澄清溶液

    此方案可获得 ≥ 2.08 mg/mL(饱和度未知)的澄清溶液。

    1 mL 工作液为例,取 100 μL 20.8 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;再向上述体系中加入 50 μL Tween-80,混合均匀;然后再继续加入 450 μL 生理盐水 定容至 1 mL

    生理盐水的配制:将 0.9 g 氯化钠,溶解于 ddH₂O 并定容至 100 mL,可以得到澄清透明的生理盐水溶液。
  • 方案 二

    请依序添加每种溶剂: 10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.08 mg/mL (5.99 mM); 澄清溶液

    此方案可获得 ≥ 2.08 mg/mL(饱和度未知)的澄清溶液。

    1 mL 工作液为例,取 100 μL 20.8 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD 生理盐水水溶液 中,混合均匀。

    20% SBE-β-CD in Saline 的配制(4°C,储存一周):2 g SBE-β-CD(磺丁基醚 β-环糊精)粉末定容于 10 mL 的生理盐水中,完全溶解至澄清透明。

Rabbits: Baseline hemodynamic parameters and temperature are obtained. The rabbits are randomized to 1 of 3 groups: a low dose of GP531, a high dose of GP 531, or vehicle (10% sodium metabisulfite). The low dose consists of a loading dose of 700 mg/kg given over 10 minutes starting at 12 minutes before coronary artery occlusion, followed by an infusion of 10 mg/kg per minute for the duration of the study. The high dose consists of a loading dose of 2100 mg/kg given over 10 minutes starting at 12 minutes before CAO followed by an infusion of 30 mg/kg per min for the duration of the study. All rabbits receive the same volume (12 mL over the duration of the study), so the concentrations are adjusted for body weight. The rabbits are then subjected to 30 minutes of coronary artery occlusion. The coronary artery is occluded by tightening the snare. Regional myocardial blood flow is measured during the ischemic period at 25 minutes of CAO[1].

Dog: Six dogs with intracoronary microembolizationinduced HF receive a constant intravenous infusion of GP531 (10 μg/kg/min) or vehicle (normal saline) for 6 h in random order 1 week apart. Hemodynamic measurements are made at baseline and at 1, 2, 3, 4, 5 and 6 h after initiating drug infusion. Myocardial oxygen consumption (MVO2) is measured at baseline and 4 and 6 h. LV pressure-volume relationship (PVR) is measured at baseline and 6 h[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
