Delanzomib is an orally active inhibitor of the chymotrypsin-like activity of proteasome with IC50 of 3.8 nM, with only marginal inhibition of the tryptic and peptidylglutamyl activities of the proteosome.

描述 | The ubiquitin-proteasome pathway plays a key role in protein processing and degradation, regulating crucial transduction pathways for cell growth and survival, including cell-cycle control, transcriptional regulation, cellular stress responses, and antigen presentation. Delanzomib (CEP-18770) is an orally active proteasome inhibitor that has potency against chymotrypsin-like proteasome activity with IC50 value of 3.8 nM[2]. In vitro, treatment with 20 nM delanzomib suppressed nuclesar factor-κB (NF-κB) mediated transcription and induced apotosis in multiple myeloma cell lines CMA-03, H929, KMM1, KMS11, KMS18, KMS27, SKMM1, U266 and RPMI-8226. Delanzomib can inhibit cell proliferation, including A2780, PC3, H460 SC, LoVo, RPMI8226 and HS-Sultan cell lines, with IC50 values of 13.7 nM, 22.2 nM, 34.2 nM, 11.3 nM, 5.6 nM and 8.2 nM, respectively. These data indicated that delanzomib exhibits a favorable cytotoxicity profile toward normal human epithelial cells, bone marrow progenitors, and bone marrow–derived stromal cells[2]. In vivo, delanzomib demonstrated dose-related inhibition of tumor proteasome activity in RPMI-8266 tumor-bearing SCID mice. Oral administration of delanzomib at 10 mg/kg twice a week resulted in a significant reduction of tumor weight and oral administration of delanzomib at 13 mg/kg resulted in complete tumor regression in RPMI-8226 subcutaneous xenograft SCID mice modelPiva R, Ruggeri B, Williams M, et al.

Treatment with delanzomib either 3 mg/kg once or twice weekly intravenously or orally at 10 mg/kg suppressed the development and gression of renal tissue renal tissue damage and extended the survival of the NZBWF1 mice with fatal lupus nephritis{{Seavey M M, Lu L D, Stump K L, et al.
