SU4312 is the racemate of (Z)-SU4312 and (E)-SU4312. (Z)-SU4312 inhibits PDGFR and FLK-1 with IC₅₀s of 19.4 and 0.8 μM, respectively. (E)-SU4312 inhibits PDGFR, FLK-1, EGFR, HER-2, and IGF-1R with IC₅₀s of 24.2, 5.2, 18.5, 16.9 and 10.0 μM, respectively^[1].

Receptor tyrosine kinases (RTKs) have been shown to be important mediators of cellular signal transduction in cells. Many RTKs have been shown to be oncogene products implicating their role in the transformation process associated with human cancers^[1].

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；该产品在溶液状态不稳定，建议您现用现配，即刻使用。

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    40% PEG300    5% Tween-80    45% saline

  Solubility: 2.08 mg/mL (7.87 mM); Suspended solution; Need ultrasonic

  此方案可获得 2.08 mg/mL (7.87 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
