MT-228 (BPN-0026709) 是一种选择性且具有血脑屏障通透性的非肌肉肌球蛋白 II (non-muscle myosin II) 抑制剂。 MT-228 通过选择性靶向非肌肉肌球蛋白 II (non-muscle myosin II) (KI = 1.5 μM) 而非心脏肌球蛋白 II (CMII) (Ki = 17 μM) 显著改善了耐受性,并且 SmMll MD 的序列与 NMllB 的序列有 83.6% 的一致性。MT-228 在精神活性物质使用障碍的动物模型中显示出持久的效果。

生物活性

MT-228 (BPN-0026709) is a selective and blood-brain barrier permeable non-muscle myosin II inhibitor. MT-228 markedly improves tolerability by selectively targeting NMIIB (KI = 1.5 μM) over CMII (KI = 17 μM), and the sequence of SmMll MD is 83.6% identical to that of NMllB. MT-228 shows long-lasting efficacy in animal models of stimulant use disorder[1].

体外研究
(In Vitro)

MT-228 (10-3-100 μM) 在 ATPase 实验中显示出比 Blebbistatin (HY-13813) 更高的心脏安全性和选择性,其 KINMIIB 值为 1.5 μM[1]
MT-228 在细胞分裂抑制方面表现出优异的效果 (EC50 = 1.0 μM)[1]

体内研究
(In Vivo)

MT 228 (5-10 mg/kg,腹腔注射,单次给药) 在小鼠中至少高达 10 mg/kg 时耐受性良好[1]
MT-228 (0.5-5 mg/kg,腹腔注射或静脉注射,单次给药) 在小鼠和大鼠中破坏对兴奋活性物质的动机依赖[1]

Animal Model: 8-10-week-old male C57BL/6 mice (25-30 g)[1]
Dosage: i.p. for a single dose
Administration: 5, 7.5, 10 mg/kg
Result: Showed no significant effects on distance travelled over the first 10 minutes or entire 40 minutes test period post-injection.
Showed no effect on velocity and no difference between time spent in the center versus the sides of the open field.
Animal Model: 8-10-week-old male C57BL/6 mice (25-30 g)[1]
Dosage: i.p. for a single dose
Administration: 0.5, 1, 2.5, 5 mg/kg
Result: Disrupted the motivation for METH at doses as low as 0.5 mg/kg.
Had no effect on a strong preference for the COC-paired chamber (5 mg/kg).
Had no effect on any measure in elevated plus maze, including the total distance travelled in the maze, latency to enter the open (unprotected) arm, or time spent in the open arm(5 mg/kg).
Animal Model: Adult male 250-300 g rats[1]
Dosage: i.v. for a single dose 30 minutes before testing
Administration: 1 mg/kg
Result: Reduced the robust lever pressing displayed by rats.
Removed the motivation to seek METH for at least one month.

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.
