Indisulam
Based on 15 publication(s) in Google Scholar
Indisulam (E 7070) is a carbonic anhydrase inhibitor with anticancer activity. Indisulam (E 7070) is a sulfonamide agent that targets the G1 phase of the cell cycle. Indisulam (E 7070) causes a blockade in the G1/S transition through inhibition of the activation of both CDK2 and cyclin E. Indisulam (E 7070) targets splicing by inducing RBM39 degradation via recruitment to DCAF15.

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
