Latest Patents

S M Kumar's latest patents showcase his expertise in the lactonization process of statins, specifically focusing on the HMG-CoA reductase inhibitors lovastatin and simvastatin. One of his notable inventions details a novel method that involves very mild reaction conditions. This improved process dissolves the open ring hydroxy acid form of the statins in an organic solvent through gentle heating. By treating this solution with a mild catalyst at controlled temperatures, he successfully promotes the crystallization of statins in lactone form. The catalyst utilized is a salt of an organic base with an organic or inorganic acid, such as pyridine hydrobromide or pyridine hydrochloride. His inventive techniques significantly enhance the efficiency and safety of statin production.

Another patent from Kumar details a different approach to the lactonization process, using an excess of acetic acid under mild heating conditions. This technique eliminates the need for strong acid catalysts and employs an anti-solvent to further aid in the crystallization of statins. The dual role of acetic acid as both a solvent and a catalyst illustrates the depth of innovation that Kumar brings to pharmaceutical processes.
