CB-5083,1542705-92-9,IC-0228686
IC50: 15.4 nM CB-5083 is an orally bioavailable inhibitor of p97. P97 is an AAA-ATPase involved in multiple cellular functions such as organelle membrane homotypic fusion and sorting of endosomal cargo. P97 is also known as valosin-containing protein which plays important roles in regulating protein homeostasis [1]. In vitro: CB-5083 is a selective potent inhibitor of p97’s second ATPase domain. CB-5083 might compete with ATP for the same binding site but may adopt a different orientation[2]. The IC50 of CB-5083 against wild-type (WT) p97 was 15.4 nM. CB-5083 could dose-dependently increase the cytosolic protein degradation in HEK293T, A549 and HCT116 cell lines [1]. CB-5083 treatment (2.5 μM) of A549 cells for 24h could induce cancer cell death [1]. In vivo: In female nude mice bearing HCT116, A549 lung carcinoma, and AMO-1 multiple myeloma xenograft tumors, oral administration of CB-5083 (100 mg/kg) for 6 h showed a significant antitumor response in tumors (TGI = 63%, p < 0.0001) [1,2]. Clinical trial: CB-5083 has entered phase 1 clinical trials in patients with multiple myeloma and solid tumors.
