"Indeed, pazopanib was shown to induce cathepsin-B activation and cell death by autophagy while sunitinib was shown to impair cathepsin-B activation and stimulate lysosomaldependent necrosis, suggesting a rationale for sequential use of these, and possibly other, tyrosine kinase inhibitors [68].4.3.2 Pazopanib in Phase II trials 4.3.2.1 Pazopanib as a first-line therapy in patients with metastatic urothelial carcinoma A Phase II trial is currently ongoing investigating the use of pazopanib in association with cisplatin in patients with advanced solid tumors including metastatic bladder cancer [69]."

"In 786-O cells, sunitinib accumulated in lysosomes and disrupted autophagic degradation by inhibiting the activity of the lysosomal protease cathepsin B, which promotes to sunitinib resistance of ccRCC ."

reach
"We found that sunitinib treatment for 24h triggers incomplete autophagy, impairs cathepsin B activation and stimulates a lysosomal dependent necrosis."

reach
"Sunitinib accumulates continuously in lysosomes, inhibiting CTSB activity and resulting in incomplete autophagic flux."
