生物活性

MK-28 is a potent and selective PERK activator. MK-28 exhibits remarkable pharmacokinetic properties and high BBB penetration in mice.

体外研究

MK-28 (0-100 μM) shows PERK selectivity in vitro on a 391-kinase panel and rescues cells (but not PERK cells) from ER stress-induced apoptosis.
ATF4 protein levels are increased signifcantly, up to 2.5-fold, in STHdhQ cells at high MK-28 concentration. CHOP and GADD34 mRNA levels show a signifcant increase in both cell types, up to 10- and 5-fold respectively.
MK-28 has little or no efect on EIF2AK1 (HRI) or EIF2AK2 (PKR), but it activats EIF2AK4 (GCN2).

Apoptosis Analysis.

Cell Line: STHdhQ cells.
Concentration: 0-100 μM.
Incubation Time: 48 h.
Result: Rescued cells from ER stress-induced apoptosis.
体内研究

MK-28 (10 mg/kg, IP, single dose) shows a maximum concentration (Cmax) of 105ng/ml and 30min half-life in plasma, 40 min afer the IP injection.
MK-28 (1 mg/kg, IP, daily for 28 days) improves systemic function and survival in R6/2 mice and induces increased levels of eIF2α-P in the mouse brain striatum.
MK-28 (Transient subcutaneous delivery) significantly improves motor and executive functions and delayed death onset in R6/2 mice, showing no toxicity.

Animal Model: R6/2 mice.
Dosage: 1 mg/kg.
Administration: IP, daily for 28 days.
Result: Incerased the survival.

请根据产品在不同溶剂中的溶解度选择合适的溶剂配制储备液;一旦配成溶液,请分装保存,避免反复冻融造成的产品失效。
储备液的保存方式和期限:-80°C, 6 months; -20°C, 1 month。-80°C 储存时,请在 6 个月内使用,-20°C 储存时,请在 1 个月内使用。

In Vivo:

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

  • 1.

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

    Solubility: 1.25 mg/mL (3.15 mM); Suspended solution; Need ultrasonic

    此方案可获得 1.25 mg/mL (3.15 mM) 的均匀悬浊液,悬浊液可用于口服和腹腔注射。

    以 1 mL 工作液为例,取 100 μL 12.5 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;向上述体系中加入50 μL Tween-80,混合均匀;然后继续加入 450 μL生理盐水定容至 1 mL。

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
