Muvalaplin
Based on 1 Customer Validation
Muvalaplin (LY3473329) 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 can be used in research on atherosclerotic cardiovascular disease.

In Vitro
Muvalaplin (LY3473329 ) (2 h) effectively inhibits the formation of Lp (a) particles with an IC50 of 0.09 nM[3].
Muvalaplin does not affect plasmin activity and reduces Lp (a) formation in a cell-free in vitro assembly assay[1].
Muvalaplin selectively binds to the apo (a) KIV8 domain with a Kd of 22 nM, demonstrating selectivity over the KIV2 domain[3].
Muvalaplin (0.001-1000 µM; 15 h) does not directly modulate plasminogen activation or plasmin activity in human platelet-poor plasma[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only. Further protocols information, click here.
In Vivo
Muvalaplin (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 (1-100 mg/kg; p.o.; q.d.; 14 days) reduces median Lp (a) levels by up to 71% in cynomolgus monkeys[3].
Muvalaplin (3.2-31.6 mg/kg; p.o.; QD; 4 days) reduces plasma plasmin activity and plasminogen protein levels in rats in a dose-dependent manner[3].

Protocols

Research Protocol for Cardiovascular Diseases
Cardiovascular disease can be modeled as maladaptive cardiac remodeling, where ischemic injury or pressure overload activates inflammatory signaling, fibroblast activation, extracellular-matrix deposition, cardiomyocyte hypertrophy, vascular remodeling, and progressive ventricular dysfunction. The TGF-β/SMAD axis is a central profibrotic pathway after myocardial injury and pressure overload, while innate immune and cytokine pathways regulate leukocyte recruitment, scar formation, and adverse remodeling. Key unresolved questions include which inflammatory signals are reparative versus harmful, when fibrosis is protective versus maladaptive, and whether pathway inhibition improves function without weakening necessary infarct healing or compensatory remodeling.
