3,5-Diiodothyropropionic acid (DITPA) is an inotropic thyroid hormone analogue of L-thyroxine (Item No. 14116) that binds to the thyroid hormone receptors TR? and TR? (Kas = 2.4 and 4.06 x 107 M-1, respectively, for human recombinant receptors).{40907} DITPA increases mRNA expression of ?-myosin heavy chain (?-MHC) in primary rat cardiomyocytes (EC50 = ~0.5 ?M). Ex vivo, DITPA prevents myocardial infarction-induced loss of contractility in rabbit cardiomyocytes when administered at a dose of 3.75 mg/kg per day.{40908} DITPA (3.75 mg/kg per day) increases expression of VEGF, basic fibroblast growth factor (bFGF), angiopoietin-1, and angiopoietin-1 receptor (Tie-2) as well as angiogenesis in non-infarcted cardiac tissue in rats.{40909} It also decreases infarct size expansion, stimulates arteriolar growth, and inhibits ventricular remodeling post-myocardial infarction in rats when administered at a dose of 3.5 mg/kg per day.{40910}
