ML162 is a covalent glutathione peroxidase 4 (GPX4) inhibitor. ML162 has a selective lethal effect on mutant RAS oncogene-expressing cell lines^[1][2]

ML162 (compound 1a) shows nanomolar potencies against two HRAS^G12V expressing cell lines, with IC₅₀ values of 25 nM and 578 nM for HRASG12V-expressing and wild-type BJ fibroblasts, respectively^[1].
ML162 (8 μM; 24 hours) treatment increases the expression of p62 and Nrf2 in chemoresistant HN3R and HN3-rslR cells, inactivates Keap1, and increases expression of the phospho-PERK-ATF4-SESN2 pathway^[2].
ML162 induces the head and neck cancer (HNC) cell death to varying degrees, with parental HN3 cells more sensitive and cisplatin-resistant (HN3R) and acquired RSL3-resistant (HN3-rslR) cells less sensitive^[2].

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
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    90% corn oil

  Solubility: ≥ 2.5 mg/mL (5.24 mM); Clear solution

  此方案可获得 ≥ 2.5 mg/mL (5.24 mM，饱和度未知) 的澄清溶液，此方案不适用于实验周期在半个月以上的实验。

  以 1 mL 工作液为例，取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL玉米油中，混合均匀。
