Kinase experiment: | KD values are measured by fluorescence polarization measurements. For direct titrations, increasing amounts of PDEδ are added to a solution containing 50-100 nM labelled small molecule in 200 µL PBS buffer. For displacement titrations, increasing amounts of the small molecules in DMSO are directly added to fluorescein-labelled atorvastatin (24 nM) and His6-tagged PDEδ (40 nM) in 200 µL PBS-buffer (containing 0.05% CHAPS, 1% DMSO), keeping the concentration of fluorescein-labelled atorvastatin, PDEδ and DMSO constant. For KD measurements using isothermal titration calorimetry, PDEδ protein (280 µM) is titrated to small molecule (30 µM) in Tris/HCl buffer (temperature 25°C). In the Tm shift assays, protein melting points are detected by circular dichroism spectroscopy in the presence of small molecules. |

Deltarasin hydrochloride is a selective inhibitor of KRAS-PDEδ interaction with IC50 value of 41±12 nM [1].
KRAS, also known as V-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog, is a protein and works as a molecular on/off switch whose mutant is an essential step in the development of many cancers. PDEδ (prenyl binding protein) controls the spatial organization of K-Ras, which enhances Ras diffusion in the cytosol. Inhibition of the Ras-PDEδ interaction by small molecules impairs Ras localization and signaling has becoming a promising strategy to treat cancers in clinic [1, 2].
Deltarasin hydrochloride is a potent KRAS-PDEδ interaction inhibitor. When tested with human pancreatic ductal adenocarcinoma cells Deltarasin hydrochloride showed inhibition on KRAS-PDEδ interaction to inhibit oncogenic RAS signaling and suppressed cell proliferation by binding to PDEδ with Kd value of 41 nM [1].
In nude mice model with Panc-Tu-I xenograft, administration of Deltarasin hydrochloride (10, 15 mg/kg) impaired cells growth and decreased tumor volume after 9 days in a dose-dependent manner [1].

计算结果:
工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
