WSB1 Degrader 1 is a poten and orally active WSB1 (WD repeat and SOCS box-containing 1) degrader. WSB1 Degrader 1 has anticancer metastatic effects^[1].

WSB1 Degrader 1 (compound 4; 0.25-2500 nM; 2-24 hours; H1299-WSB1 cells) treatment indues WSB1 degradation in time-dependent and dose-dependent manners^[1].
WSB1 Degrader 1 (compound 4) exhibits potent antimigration efficacy in both KHOS and H460 cell lines with IC₅₀ values of 39.1 μM and 24.47 μM, respectively^[1].
WSB1 Degrader 1 (compound 4) significantly inhibits cancer cell migration under normoxia and hypoxia in KHOS cells. WSB1 Degrader 1 (5 μM) treatment elevates the levels of the RhoGDI2 protein in KHOS cells under hypoxia^[1].
The wound-healing of H1299-WSB1 cells is significantly inhibited by treating with WSB1 Degrader 1. WSB1 Degrader 1 can only block the wound-healing capability of wild-type A2780 (A2780-WT) cells but not the A2780-WSB1/KO cells^[1].

WSB1 Degrader 1 (compound 4; 100 mg/kg; p.o.; daily; for 28 days) treatment can effectively inhibit the pulmonary metastasis of cancer cells^[1].
In rats, after 100 mg/kg oral dosing or 160 mg/kg intraperitoneal dosing of WSB1 Degrader 1 (compound 4), the two ways of administration are observed with quick absorption (Tmax), but the former dosing displayed a fast clearance (T_1/2). Moreover, C_max and AUC_0-t values of WSB1 Degrader 1 in oral or intraperitoneal dosing groups showed acceptable blood exposure^[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；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    40% PEG300    5% Tween-80    45% saline

  Solubility: ≥ 2.08 mg/mL (6.22 mM); Clear solution

  此方案可获得 ≥ 2.08 mg/mL (6.22 mM，饱和度未知) 的澄清溶液。

  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
