DS68591889
Based on 1 Customer Validation
DS68591889 is a selective and orally active phosphatidylserine synthase 1 (PTDSS1) inhibitor. DS68591889 has no inhibitory activity against PTDSS2. DS68591889 induces the phospholipid imbalance in a wide range of cancer cells. DS68591889 negatively regulates B cell receptor (BCR)-induced Ca2+ signaling and subsequent apoptotic cell death. DS68591889 can be used for the cancer research, such as B cell lymphoma.

Biological Activity
PTDSS1[1]
DS68591889 (0.1-1000 nM; 4-6 days) strongly suppresses the growth of malignant B cell lymphoma-derived lines[1].
DS68591889 (100 nM; 3 days) enhances BCR-induced Ca2+ signaling and cell apoptosis in Ramos cells1.
DS68591889 (100 nM; 3 days) increases IP1 production, changes the levels of PI4P and PI(4,5)P2, and affects the subcellular localization of related proteins in Ramos cells1.
DS68591889 (100 nM; 24 hours) increases the PIP level, and alters the phospholipid metabolism related to ORP5/8 and Nir2/3 and the BCR-induced Ca2+ response in Ramos cells1.
In HeLa cells, DS68591889 (10-1000 nM; 2 days) causes a substantial loss of phosphatidylserine (PS) and phosphatidylethanolamine (PE), along with a slight decrease in phosphatidylglycerol (PG) and sphingomyelin (SM) and an increase in phosphatidic acid (PA)[1].
In a panel of 47 human cancer cell lines, DS68591889 causes a reduction of PS levels in a wide range of cell lines. DS68591889 reduces the levels of major PS acyl-chain species such as C36:1-PS and C34:1-PS, whereas it slightly increased the level of C40:6-PS, which is mainly produced by PTDSS2. DS68591889 also causes a profound reduction of C36:1-PE and C34:1-PE, indicating substantial PE production from PS species by PS decarboxylase in mitochondria[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: 5 mg/mL (8.33 mM); Clear solution; Need ultrasonic
This protocol yields a clear solution of 5 mg/mL.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
