Latest Patents
One of Haider's latest patents is focused on nucleophilic catalysts for oxime linkage. This invention relates to materials and methods for conjugating a water-soluble polymer to an oxidized carbohydrate moiety of a therapeutic protein. The process involves contacting the oxidized carbohydrate moiety with an activated water-soluble polymer under conditions that facilitate conjugation. Specifically, the water-soluble polymer contains an active aminooxy group, allowing for the formation of an oxime or hydrazone linkage. The conjugation is carried out in the presence of a nucleophilic catalyst, enhancing the efficiency of the process.
Another significant patent by Haider involves blood coagulation protein conjugates. This invention also focuses on the conjugation of a water-soluble polymer to an oxidized carbohydrate moiety, specifically within blood coagulation proteins. Similar to his previous patent, this method utilizes an active aminooxy group to form an oxime linkage. In one embodiment, the conjugation is performed in the presence of the nucleophilic catalyst aniline, and the generated oxime linkage can be stabilized by reduction with NaCNBH to form an alkoxyamine linkage.
