Synthetic and Immunological Studies of sTn Derivatives Carrying 5-N-(p-Substituted Phenylacetyl)Sialic Acid for the Development of Effective Cancer Vaccines.

abstract：:The self-assembly of amyloid proteins into β-sheet rich assemblies is associated with human amyloidoses including Alzheimer's disease, Parkinson's disease, and type 2 diabetes. An attractive therapeutic strategy therefore is to develop small molecules that would inhibit protein self-assembly. Natural polyphenols are p...
