Muvalaplin tetrahydrochloride
Based on 1 Customer Validation
Muvalaplin tetrahydrochloride (LY3473329 tetrahydrochloride) is an orally active small molecule apolipoprotein a (apolipoprotein a) inhibitor that binds to the KIV8 domain (Kd = 22 nM) and kringle IV domains 7 and 8, blocks the non-covalent interaction between apo (a) and apoB-100, and prevents Lp (a) assembly, thereby lowering circulating Lp (a) levels. Muvalaplin tetrahydrochloride can be used in research on atherosclerotic cardiovascular disease.

In Vitro
Muvalaplin tetrahydrochloride selectively binds to the apo (a) KIV8 domain with a Kd of 22 nM, demonstrating selectivity over the KIV2 domain[3].
Muvalaplin tetrahydrochloride (0.001-1000 µM; 15 h) does not directly modulate plasminogen activation or plasmin activity in human platelet-poor plasma[3].

In Vivo
Muvalaplin tetrahydrochloride (1-100 mg/kg; p.o.; twice daily; 5 days) reduces Lp (a) levels in Lp (a) transgenic mice with an ED50 of 3 mg/kg and a maximum reduction of 92%[3].
Muvalaplin tetrahydrochloride (1-100 mg/kg; p.o.; q.d.; 14 days) reduces median Lp (a) levels by up to 71% in cynomolgus monkeys[3].
