Cayman Dsr 6434; Qty- 5; Size-5 Mg

Zotarolimus is a macrocyclic lactone immunosuppressant and a derivative of rapamycin (Item No. ).^, It binds to FKBP prolyl isomerase 1A (FKBP12; IC₅₀ = 2.57 nM) and inhibits proliferation of human peripheral blood mononuclear cells (PBMCs), rat splenocytes, and human coronary artery smooth muscle cells (IC₅₀s = 7, 1,337, and 0.8 nM, respectively). Zotarolimus has immunosuppressive activity in a one-way mixed lymphocyte reaction using human or rat lymphocytes (IC₅₀s = 1.2 and 1,465 nM, respectively). It also reduces symptom severity in a rat model of experimental autoimmune encephalomyelitis (EAE; ED₅₀ = 1.17 mg/kg per day) and delays cardiac allograft rejection in rats (ED₅₀ = 3.71 mg/kg per day). Zotarolimus inhibits neointimal formation and reduces stenosis in pig coronary arteries when applied at 10 µg/mm to stainless steel balloon expandable stents with phosphorylcholine in a model of restenosis. Formulations containing zotarolimus have been used in drug-eluting stents in the prevention of restenosis following stent placement.
