DRB18（Cat No.:I043839）is a selective small molecule inhibitor that targets specific proteins involved in cellular processes such as transcription regulation and DNA repair. It is often utilized in research focusing on the modulation of RNA polymerase II activity and its role in gene expression. DRB18 has shown potential in studies related to cancer, neurodegenerative diseases, and other conditions where dysregulation of transcriptional mechanisms is involved. By inhibiting key steps in RNA processing and transcription, DRB18 is a valuable tool for understanding gene regulation and exploring therapeutic strategies for various diseases.
