    摘要: A synthetic nucleus pulposus is provided that is useful in treatment of degenerative disc disease, augmentation of a degenerate disc, and alleviation of back pain. In an embodiment the synthetic nucleus pulposus comprises hyaluronan macromolecules that have been cross-linked via dihydroxyphenyl linkages. The synthetic nucleus pulposus restores or improves the water-retention capability of the disc. A method of treating an intervertebral disc with the cross-linked hyaluronan macromolecules is also provided. A method of regenerative therapy to address loss of cells of nucleus pulposus of an intervertebral disc based on treatment with the cross-linked hyaluronan macromolecules and mesenchymal stem cells is also provided.

    摘要: Method for the synthesis of a compound of formula H(OCH[CH3]CH2C[O])3—O-A-O—R wherein A is the residue of 1,3-butandiol and R is H or H(OCH[CH3]CH2C[O]3—. The method comprises reacting a cyclic oligomer of (R)-3-hydroxybutyrate consisting of (R)-3-hydroxybutyrate moieties with a 1,3-butandiol in an organic solvent in the presence of Candida antarctica lipase type B in a furan or pyran solvent.
