Latest Patents

One of her latest patents is titled "Process for bioreduction of bisaryl ketone to bisaryl alcohol." This invention focuses on an improved method for creating PDE IV inhibitors. Specifically, it describes a process for making and purifying a chiral bisaryl alcohol, which is an essential intermediate for the preparation of PDE IV inhibitors like CDP 840. The process utilizes a microorganism's ability to reduce a pro-chiral bisaryl ketone to the chiral bisaryl alcohol, which can then be isolated through various purification methods. This innovation enhances the production of each enantiomer of the bisaryl alcohol at elevated optical purity.

Another significant patent is the "Method of purifying recombinant pres-1/S-2/S/S hepatitis B antigen." This invention outlines a rapid purification method for recombinant hepatitis B antigen that is bound to yeast membranes in yeast expression systems. The method involves using agents that release undesired proteins, followed by agents that specifically release the recombinant hepatitis B antigen.
