Heart failure is a health problem worldwide. There are some drugs for it, including digoxin, spironolactone, captopril, and valsartan, but some of these drugs can produce secondary effects, such as arrhythmia, cough, hyperkalemia, hyponatremia and hypotension. The aim of this research was to evaluate the biological activity of coumarin (2H-chromen-2-one) and its derivatives (3BrAcet-C, 3-4Br-Ph-C, 4-CN-7D-C, 4-Me-7-Ph-C and 6Br-3-D-C) against ischemia/reperfusion injury as a therapeutic alternative for heart failure.

However, some studies indicate that this phenomenon could also occur in cancer cells. It is important to mention that some amino derivatives have been prepared as VEGF-R1 inhibitors; however, their interaction with VEGF-R1 is not clear, perhaps due to different experimental approaches or differences in their chemical structure.

Objective: The objective of this investigation was to evaluate the inotropic activity of ten Dibenzo derivatives (compounds 1 to 10) on either perfusion pressure or left ventricular pressure.
Methods: Biological activity produced by the Dibenzo derivatives on either perfusion pressure or coronary resistance was evaluated using an isolated rat heart.
Background: There are studies that suggest that some benzamide derivatives may exert effects on heart failure; however, their molecular mechanism is not very clear.
Objective: The aim of this research was to evaluate the biological activity of a 4-hydroxy-furanyl-benzamide derivative against heart failure translated as area infarct.
Methods: Biological activity produced by 4-hydroxy-furanyl-benzamide derivative against heart failure was determinate using an ischemia-reperfusion injury model.
Background: There are reports which indicate that some cyclooctyne derivatives may exert changes in cardiovascular system; however, its molecular mechanism is not very clear.
Objective: The aim of this study was to evaluate the biological activity of four cyclooctyne derivatives (compounds 1: to 4: ) produced on infarct area and left ventricular pressure.
Methods: Biological activity produced by cyclooctyne derivatives on infarct area was determinate using an ischemia/reperfusion injury model.
Background: There are studies, which suggest that some diazocine derivatives can exert effects on the cardiovascular system; however, these effects are not very clear.
Objective: The aim of this research was to evaluate the biological activity of a diazocine derivative against heart failure translated as area infarct.
Methods: Biological activity produced by diazocine derivatives against heart failure was determinate using an ischemia/reperfusion injury model.
Background: Several drugs with inotropic activity have been synthesized; however, there is very little information on biological activity exerted by steroid derivatives in the cardiovascular system.
Objective: The aim of this research was to prepare a steroid-pyridine derivative to evaluate the effect it exerts on left ventricular pressure and characterize its molecular interaction.
Methods: The first stage was carried out through the synthesis of a steroid-pyridine derivative using some chemical strategies.
