Latest Patents

One of his latest patents is an automated system for polynucleotide synthesis and purification. This innovative method employs solid phase synthesis on a nonswellable porous polystyrene support using phosphoramidite or hydrogen phosphonate chemistries. The polystyrene support minimizes tritylated failure sequences caused by chain growth from extraneous support sites. It also allows for the use of lower amounts of monomer reactants while achieving equal or better coupling efficiencies compared to conventional methods. Additionally, the system utilizes nucleoside intermediates with exocyclic amines protected by base-labile groups. This feature enables simultaneous cleavage and deprotection of the completed polynucleotide chain in the presence of the solid phase support, facilitating practical automation of both synthesis and purification processes.
