structures in the region surrounding C312. It was found that treatment of 250 nM THZ1 was sufficient to inhibit global transcription and that cancer cell lines were sensitive to much lower concentrations, opening up further research into the efficacy of using THZ1 as a component of cancer therapy, as described above. In renal cell carcinoma (RCC), the expression of CDK7 was significantly higher in the advanced stage tumors. Besides, the overall survival was significantly shorter in patients with higher CDK7 expression in the tumors. These results suggest that CDK7 may be a potential target for overcoming RCC. Based on molecular docking results, Ligands-3, 5, 14, and 16 were screened among 17 different Pyrrolone-fused benzosuberene compounds as potent and specific inhibitors without any cross-reactivity against different CDK isoforms. Analysis of MD simulations and MM-PBSA studies, revealed the binding energy profiles of all the selected complexes. Selected ligands performed better than the experimental drug candidate (Roscovitine). Ligands-3 and 14 show specificity for CDK7. These ligands are expected to possess lower risk of side effects due to their natural origin. In urothelial carcinoma (UC), CDK7 expression is increased in bladder cancer tissues, especially in patients with chemoresistance. CDK7 inhibition-related cancer stemness suppression is a potential therapeutic strategy for both chemonaïve and chemoresistant UC. Interactions Cyclin-dependent kinase 7 has been shown to interact with: Androgen receptor, Cyclin H, GTF2H1, MNAT1, P53, SUPT5H, and XPB.
