Prediction of Activity Spectra and Synthesis of Some Substituted Coumarins

Abstract

Coumarin nucleus containing drugs have its own importance in drug chemistry. Coumarins and its substituted compounds possess various pharmacological activities and can be used in the treatment of cancer. Compounds of coumarins and substituted coumarins are prepared from phenol and malonic acid by cyclization with POCl₃ and fused ZnCl₂ and their activity were examined by computer based programmed called PASS (prediction of activity spectra for substances). The result of PASS studies shows that the substituted coumarins and unsubstituted coumarins show many important biological activities. Among that the unsubstituted coumarins shows properties such as phosphatase inhibitors, CYP2A3 substrate, antianemic, nitrate reductase inhibitor, histamine release inhibitor, etc. Predicted result shows that unsubstituted coumarins show strong activities than substituted coumarins.
