Abstract: A dental care product comprises an orally acceptable carrier or excipient, and a bacterial resistance copolymer, which comprises a zwitterionic block and a charged anchoring block, wherein the anchoring block binds to tooth surfaces by electrostatic attraction, and the zwitterionic block extends outwardly to reduce the attachment of bacteria to tooth surfaces.

Abstract: A precursor used for labeling hepatocyte receptors and applied to radiotracers for imaging or pharmaceutical compositions for liver cancers is revealed. The precursor is a bifunctional compound. The bifunctional group includes a trisaccharide structure and a diamide dimercaptide (N2S2) ligand. The trisaccharide has high affinity to asialoglycoprotein receptors (ASGPR) on surfaces of hepatocytes while N2S2 ligand reacts with radioisotopes to form neutral complexes. Thus the precursor stays on surfaces of hepatocytes to provide radioisotope labeling or treatment effect of liver cancers.

Abstract: A precursor SnBZM for a dopamine receptor radiotracer and a method for preparing the same are revealed. The precursor includes a tributyltin group (Bu3Sn) that is easy to be replaced. Thus a dopamine receptor radiotracer 123I-IBZM can be produced at high yield rate by a substitution reaction of the precursor. At the same time, both the method for preparing the precursor SnBZM and a method for preparing a reference standard IBZM are simplified. Moreover, stability of each product is improved.
