专利号:US-11034664-B1 优先权日:2020-05-11 标题 :Synthesis of cyclic carbonate monomers 发明人:PARK NATHANIEL H; HEDRICK JAMES L; PIUNOVA VICTORIA A; ARRECHEA PEDRO; ERDMANN TIM 权利人:IBM 摘要:Techniques regarding the synthesis of cyclic carbonate monomers are provided. For example, one or more embodiments described herein can comprise a method, which can include cyclizing a functionalized diol monomer with N,N′-carbonyldiimidazole, wherein the cyclizing produces a cyclic carbonate monomer and an imidazole carbamate. The method can also include activating the imidazole carbamate with an acid, wherein the activating promotes cyclization of the imidazole carbamate into the cyclic carbonate monomer.

专利号:US-2008125354-A1 优先权日:2005-11-21 标题 :Selective inhibition of matrix metalloproteinases 发明人:FIELDS GREGG B; HAMMER ROBERT 权利人:UNIV FLORIDA ATLANTIC; UNIV LOUISIANA STATE 摘要:Synthetic triple-helical peptides (THPs) are used for the design and synthesis of triple-helical transition state analog inhibitors. These inhibitors feature a phosphonate ester or phosphinic moiety in place of the scissle bond. These groups inhibit MMPs, and methods been developed for their convenient incorporation within a peptide sequence by solid-phase methods.
