Novel Synthesis and Characterization of Irbesartan Derivative an Anti‐Hypertensive Active Pharmaceutical Ingredient (API)

Abstract

AbstractThe current research focuses on the design, method development, characterization, and clinical assessment of novel irbesartan medication compounds. The objective of synthetic modification of a drug molecule is to achieve the desired properties such as enhancing the pharmacological properties and minimizing the side effects. It is a biphenyl tetrazole and an aza‐spiro compound, a highly selective, potent nonpeptide compound that belongs to the sartan group, an authorized type‐1 angiotensin II receptor (AT1), dilates the blood vessels and is used in curing of to treat high blood pressure, cardiac arrest, and renal disease in diabetics. To achieve the structural modification of the irbesartan drug, the researcher prepared the FeCl3/SiO2 catalyst and successfully used it for the acetylation, chloro acetylation reaction of irbesartan with acetyl chloride and chloroacetyl chloride. Further, the reaction is performed in presence of the catalyst and without a catalyst to elucidate the role of the catalyst. With the aid of TLC, FT‐IR, and UV–visible spectral methods, the structural interpretation of synthesized derivatives is completed. The present work illustrates a novel method of synthesis of irbesartan derivatives through safe and convenient procedures. The pharmacological evaluation of synthetic derivatives and green chemistry protocol of synthesis is under progress.
