  • Publication number: 20210395463
    Abstract: In an aspect, a method of synthesizing a graft copolymer comprises the steps of: copolymerizing a first macromonomer and a first reactive diluent; wherein said first macromonomer comprises a first backbone precursor directly or indirectly covalently linked to a first polymer side chain group; wherein said reactive diluent is provided in the presence of the first macromonomer at an amount selected so as to result in formation said graft copolymer having a first backbone incorporating said diluent and said first macromonomer in a first polymer block characterized by a preselected first graft density or a preselected first graft distribution of said first macromonomer. In some embodiments of this aspect, said preselected first graft density is any value selected from the range of 0.05 to 0.75. In some methods, the composition and amount of said diluent is selected to provide both a first preselected first graft density and a first preselected first graft distribution.

  • Publication number: 20210340504
    Abstract: Genetically-modified cell capable of producing UD CA, cholic acid, and/or another UDCA precursor comprising at least one heterologous polynucleotide encoding an enzyme involved in a metabolic pathway that converts sugar to UDCA, cholic acid, and/or another UDCA precursor. Method of making UDCA, cholic acid, and/or another UDCA precursor using such a cell. Use of UDCA or UDCA precursor produced using such a method for the manufacture of a medicament for the treatment of a disease or symptom of a disease. Medicament comprising UDCA or UDCA precursor made using such a method. Method of treating a disease or symptom of a disease comprising administering UDCA or a UDCA precursor made using such a method. Isolated nucleic acid encoding at least one enzyme involved in a metabolic pathway that converts sugar to UDCA, cholic acid, and/or another UDCA precursor.
