GW406108X is a specific Kif15 (Kinesin-12) inhibitor with an IC₅₀ of 0.82 uM in ATPase assays. GW406108X, a potent autophagy inhibitor, shows ATP competitive inhibition against ULK1 with a pIC₅₀ of 6.37 (427 nM). GW406108X inhibits ULK1 kinase activity and blocks autophagic flux, without affecting the upstream signaling kinases mTORC1 and AMPK^[1][2].

GW406108X acts upon ULK1 and autophagy without affecting mTOR or AMPK activity as shown by monitoring ULK1 pS758 (mTOR site) or pS556 (AMPK site) levels. GW406108X inhibits VPS34 and AMPK with pIC₅₀ of 6.34 (457 nM) and 6.38 (417 nM), respectively. In the presence of 5 µΜ GW406108X, the starvation-induced increase in ATG13 phosphorylation is significantly reduced^[1].
GW406108X inhibits Kif15-N420 ATPase activity by 76%^[2].

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
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

• 1.

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

  Solubility: 2.08 mg/mL (5.20 mM); Suspended solution; Need ultrasonic

  此方案可获得 2.08 mg/mL (5.20 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 20.8 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。

  将 0.9 g 氯化钠，完全溶解于 100 mL ddH₂O 中，得到澄清透明的生理盐水溶液
