Screening of natural products atlas for identification of lead molecule to treat angina pectoris using bioinformatics approaches

Angina pectoris is amongst the most common diseases. There is a scarcity of effective treatments for this disease. As a result, there is a significant clinical and social interest in predicting and developing novel compounds to treat cardiovascular disorders. So, specific natural products have been screened in this study because they have protective effects against angiotensin-converting enzymes. When taken orally, natural products can help protect against or lessen the severity of angina and heart damage. Natural compounds inhibit regulatory enzymes for controlling Angina. For this, we used computational methods such as drug design to identify novel natural compounds against cardiovascular diseases. Drug design via computational methods is gaining popularity as a quick and effective method to identify lead compounds in a shorter time at a low cost. This research work aims to predict novel lead inhibitor compounds against ACE to treat angina pectoris. This would ensure that, in early preclinical studies, there will be lower failure rates due to the demonstrated safety profiles of the predicted compounds.

Study on development and tissue permeation of different formulations of Fasudil

OBJECTIVE

The study is intended to formulate Fasudil loaded vesicular system for application in the management of angina.

MATERIALS AND METHODS

Fasudil was made into a complex with phospholipid, and other different formulations were made, including Fasudil solution, liposomal form, and Fasudil loaded into the gel. A drug characterization study was conducted and noted. Drug release was quantified and analyzed and, finally, inoculated in Sprague-Dawley rats. These rats underwent anginal induction, and each formulation's effect on angina was evaluated.

RESULTS

Drug solution (F-Phos) and F-Phos-Lipo (liposomal dispersion form of the drug) have shown that more than half percent of them have been released within 1.5 hours, and the rapid release occurred from liposomal dispersion in the first hour. The study determined the viscosity of the different formulations, which was significantly (p<0.05) higher than the theoretical sum of the viscosity of each formulation. The study found that the F-Phos-Lipo+P-407HMS formulation is the most effective as its application has the minimum infarct area percentage compared to the other formulations and can also reduce creatine kinase levels significantly as compared to the different formulations (p<0.05).

CONCLUSIONS

The study concluded that the typical gel formulation (liposomal Fasudil dispersed in hydroxypropyl methylcellulose solution, which is added to blank poloxamer 407) had been shown to have significantly anti-anginal properties, including easy administration, its application on the infarct area percentage and subsequently its pharmacological effect on the cardiac tissue.
