INTRODUCTION: Mangiferin and its derivatives possess diverse biological activities and desirable drug like properties. In continuation with the authors' previous publication, the present study reviews recently published patents in correlation with efforts of drug development using mangiferin.
AREAS COVERED: Patents published after the year 2013 were analyzed for therapeutic and cosmetic applications of mangiferin, its salts, derivatives, and preparations. Patent information pertaining to improving solubility and bioavailability of mangiferin and related bioactives has also been presented. Methods of extraction of mangiferin and poly herbal preparations have not been included. Biological testing data has been put forth to understand the clinical trial status of products comprising mangiferin and/or its derivatives.
EXPERT OPINION: Mangiferin has been highlighted as a multitarget bioactive with therapeutic potential. Research efforts in the recent years have contributed to development of new mangiferin derivatives as well as mangiferin formulations with enhanced solubility and bioavailability. Improvements in drug delivery systems for mangiferin might contribute to designing clinical trials to validate its therapeutic potential in humans. Majority of the recent patents have been filed by Chinese inventors claiming second medical use of mangiferin or its related compounds. However, a number of these patents remain in the prosecution stage.
