New Amino-steroid-anthracenone with Biological Activity Against Ischemia-reperfusion Injury in a Wistar Rat Model

Abstract

Objective: The main objective of this study was to evaluate the biological activity of an ASA (Amino-Steroid-Anthracenone derivative) against heart failure caused by the ischemia- reperfusion injury (translated as infarct area). Methods: Biological activity exerted by ASA (0.001-100 nM) on infarct area was determined using an ischemia-reperfusion injury model. In addition, to characterize the molecular mechanism involved in the effect exerted by ASA on left ventricular pressure, some drugs such as estrone (0.001-100 nM), tamoxifen (1 nM), butoxamine (1 nM) and ZM-241385 (1 nM) were used. Results: The experimental data showed that ASA decreased the infarction area significantly (p = 0.05) compared to estrone. Other results indicated that ASA decreased left ventricular pressure and this effect was inhibited by ZM-241385. In addition, ASA increased cAMP levels in a time-dependent manner compared to control conditions. Conclusion: The results showed that ASA decreases ischemia-reperfusion injury (translated as infarct area) via A2 adenosine receptor activation and these phenomena involve changes in cAMP levels.

Preparation of a steroid-oxazole-1,2′-[1,3]oxazete] derivative: biological and theoretical evaluation of its interaction with a kinase protein (CK2)

“…There are some reports which indicate that some steroid derivatives can exert changes in the perfusion pressure in vitro [46]. To evaluate this data, the biological activity induced by the compounds 2-4 on perfusion pressure (translated as changes in on blood vessel capacity and coronary resistance) was evaluated using an isolated rat heart model.…”
