Abstract:
Aim: Hypertension is a major health problem worldwide resulting in high death rates due to its consequences and complications. Therefore, searching for new vasorelaxants is a must to find new vasodilators efficient for the treatment of different cardiovascular diseases. Methodology: Different 6-phenyl-3-pyridazinone based derivatives were synthesized and screened for their vasorelaxant activity according to the reported method using hydralazine as a standard. Results: The tested compounds revealed potent to mild activity with EC50 values 0.339–114.300 μM compared with hydralazine EC50 = 18.210

Abstract:
To investigate vasorelaxant effect of ethanol extracts from M. vulgare, it is part of a group of plants subjected to pharmacological and phytochemical study with the purpose of offering it as an ideal source for obtaining lead compounds for designing new therapeutic agents with potential vasorelaxant and antihypertensive effects. In this context, all extracts caused concentration-dependent relaxation in -precontracted aortic rings with and without endothelium; the most active extract was EERMv. These results suggest that secondary metabolites responsible for the vasorelaxant activity belong to

Abstract:
Silymarin is a traditional drug and food supplement employed for numerous liver disorders. The available studies indicate that its activities may be broader, in particular due to claimed benefits in some cardiovascular diseases, but the contributions of individual silymarin components are unclear. Therefore, we tested silymarin flavonolignans as pure diastereomers as well as their sulfated metabolites for potential vasorelaxant and antiplatelet effects in isolated rat aorta and in human blood, respectively. Eleven compounds from a panel of 17 tested exhibited a vasorelaxant effect, with half m

The inclusion complexes were prepared by lyophilization and the nanocapsules by the preformed polymer interfacial deposition method. The solubility isotherms determined for NDIBP showed Al-type profiles (K1:1 = 33.0 M-1). The formation of the inclusion complex provided a 12.5-fold increase in the solubility of NDIBP.

Abstract:
Terpenes are a class of chemical compounds with carbon and hydrogen atoms in their structure. They can be classified into several classes according to the quantity of isoprene units present in its structure. Terpenes can have their structure modified by the addition of various chemical radicals. When these molecules are modified by the addition of atoms other than carbon and hydrogen, they become terpenoids. Terpenes and terpenoids come from the secondary metabolism of several plants. They can be found in the leaves, fruits, stem, flowers, and roots. The concentration of terpenes and terpenoid
