RSM-932A has a potent anti-proliferative activity against most tumor-derived cell lines tested, including those derived from breast, lung, colon, bladder, liver, ovary, bone, cervix, kidney, pancreas, melanoma, and brain tumors, with IC50s of 1.3-7.1 μM for 72 hours[1].
RSM-932A (TCD-717; 2-4 μM; for 24 hours) promotes cell death of colon cancer cells[2].
RSM-932A (2-10 μM) exhibits a dosage-dependent decrease in the levels of thymidylate synthase (TS) and thymidine kinase (TK1) proteins proteins[2].
RSM-932A inhibits Streptococcus pneumoniae choline kinase (sChoK) with IC50 of 0.5 μM in LDH/PK and colorimetric enzymatic assays[3].
The minimum inhibitory concentration (MIC) of RSM-932A for S. pneumoniae is 0.4 μM, and the minimum lethal concentration (MLC) is 1.6 μM[3].
RSM-932A is a comparatively potent inhibitor with the IC50 of 1.75 μM in a steady-state reaction in which the concentration of Choline is equivalent to its Km[4].

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 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 1.67 mg/mL (1.90 mM); Clear solution
This protocol yields a clear solution of ≥ 1.67 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (16.7 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
