AZD5582

Research use only, not for human use.

AZD5582 is a dimeric Smac mimetic, potent IAP antagonist.

AZD5582 is a dimeric Smac mimetic, potent IAP antagonist that binds potently to the BIR3 domains of cIAP1, cIAP2 and XIAP with IC50 of 15, 21and 15 nM, respectively; causes cIAP1 degradation and induces apoptosis in the MDA-MB-231 breast cancer cell line at subnanomolar concentrations in vitro; induces cIAP1 degradation and caspase-3 cleavage within tumor cells and causes substantial tumor regressions in MDA-MB-231 xenograft-bearing mice.

AZD5582 (20 nM; 48 hours) inhibits cell viability by cooperation with IFNγ or viral double-stranded RNA (dsRNA) in H1975 NSCLC cells.AZD5582 (20 nM; 17 or 25 hours) downregulates cIAP-1, activates RIPK1 (upstream regulator of caspase-8), and triggers the activation of extrinsic (caspase-8) and intrinsic (caspase-9) apoptosis pathways, causing the cleavage of caspase-3 and caspase-7.AZD5582 (20 nM; 48 hours) involves in apoptosis due to induction of cell death and active caspase-3/8 activities by AZD5582 and IFNγ co-treatment in HCC827 NSCLC cells. Cell Viability Assay Cell Line:H1975 NSCLC cell line Concentration:20 nM Incubation Time:48 hours Result:Cooperated with IFNγ or viral double-stranded RNA (dsRNA) to inhibit cell viability even cell death.Apoptosis Analysis Cell Line:HCC827 NSCLC cell line Concentration:20 nM Incubation Time:48 hoursResult:Had an inhibitory effect on cell viability by cooperating with IFNγ.Western Blot Analysis Cell Line:H1975 NSCLC cell line Concentration:20 nM Incubation Time:17 or 25 hours Result:Down-regulated cIAP-1, activated RIPK1 (upstream regulator of caspase-8), triggered the cleavage (activation) of caspase-3,7,8 and 9.

AZD5582 (intravenous injection; 0.1-3.0 mg/kg; once a week; 2 weeks) causes degradation of cIAP1 and caspase 3 cleavage in tumor cells, and after a two-week treatment, the tumors largely resolved; when the mice are given a medium dose (0.5 mg/kg) of AZD5582, cIAP1 degrades after administration, but it takes a while time to reach apoptosis-inducing effect. Animal Model:MDA-MB-231 xenograft-bearing mice Dosage:0.1 mg/kg, 0.5 mg/kg, 3.0 mg/kg Administration:Intravenous injection; once a week; 2 weeks Result:Resulted in cIAP1 degradation and caspase-3 cleavage within tumor cells and causes substantial tumor regressions following two weekly doses of 3.0 mg/kg
