Five potential therapeutic targets in the contractile apparatus for small molecules. Original figure was made by using BioRender.com. The availability of myosin heads for interaction can be ameliorated via myosin activators or alleviated by myosin inhibitors. Similarly, affinity of troponin C towards Ca²⁺ ions can be increased (Ca²⁺-sensitisers) or decreased (Ca²⁺-desensitisers). Protein kinase A (PKA)-dependent phosphorylation of TnI was found to be lost in some forms of hypertrophic cardiomyopathy (HCM) and dilated cardiomyopathy (DCM), but it can be restored via Recouplers. Figure was created by using Biorender.com.
