Discovery of a Novel Co-crystal of Chrysin and Oroxylin A with Anticancer Properties from Leaves of Oroxylum indicum

This study presents the first report on the discovery of a naturally occurring co-crystal of chrysin and oroxylin A and the involvement of ERKs and p38 of MAPK pathways in the induction of apoptosis in HeLa cells by the co-crystal. Our study sheds light on the development of a co-crystal of chrysin and oroxylin A in a specific ratio of 1:1 for combination therapy of the two APIs. The purified co-crystal was found to be more efficient compared to the compounds present individually. Further analysis of the physiochemical properties and molecular mechanisms of the isolated co-crystal in different cancer cells is warranted for its application in therapeutics.
