Page/Page column 35; 36, (2019/10/01)
The present invention relates in part protective groups that can be used to reversibly protect benzoxaboroles and/or oxaboroles and yield the corresponding protected complexes. The invention further relates to the use of these protective groups to protect benzoxaboroles and/or oxaboroles.

The synthesis and utility of three benzoxaborole protecting groups are reported. These protecting groups improve organic solubility and allow otherwise incompatible reactions (oxidations, substitutions, and mild reductions) to be achieved in the presence of the benzoxaborole moiety. 3-(N,N-Dimethylamino)-1-propanol was determined to be useful in one-step sequences and is readily cleaved upon workup. Two other groups, N-methylsalicylidenimine and 2-[1-(methylimino)ethyl]phenol, are suitable for multistep syntheses. Deprotection with mild aqueous acid allows for chromatography-free isolation of the benzoxaborole in high yields.

Molecular recognition of carbohydrates plays vital roles in biology but has been difficult to achieve with synthetic receptors. Through covalent imprinting of carbohydrates in boroxole-functionalized cross-linked micelles, we prepared nanoparticle receptors for a wide variety of mono- and oligosaccharides. The boroxole functional monomer bound the sugar templates through cis-1,2-diol, cis-3,4-diol, and trans-4,6-diol. The protein-sized nanoparticles showed excellent selectivity for daldohexoses in water with submillimolar binding affinities and completely distinguished the three biologically important hexoses (glucose, mannose, and galactose). Glycosides with nonpolar aglycon showed stronger binding due to enhanced hydrophobic interactions. Oligosaccharides were distinguished on the basis of their monosaccharide building blocks, glycosidic linkages, chain length, as well as additional functional groups that could interact with the nanoparticles.

Paragraph 0081; 0082, (2016/08/29)
The present invention provides a compound represented by formula I, wherein R is a halogen element or a C1-C6 alkyl group. The compound has S1 P1 receptor agonist activity and selective specificity and has obviously-shortened half-life in-vivo, and therefore the compound is a high-quality second-generation S1P1 receptor agonist. The present invention also provides a use of the compound in preparing medicine for treating diseases or symptoms mediated by an S1P1 receptor, a pharmaceutical composition comprising the compound, and uses of the compound and the pharmaceutical composition in treating diseases or symptoms mediated by the S1 P1 receptor.

We disclose here a series of P4-benzoxaborole-substituted macrocyclic HCV protease inhibitors. These inhibitors are potent against HCV NS3 protease, their anti-HCV replicon potencies are largely impacted by substitutions on benzoxaborole ring system and P2 groups. P2 2-thiazole-isoquinoline provides best replicon potency. The in vitro SAR studies and in vivo PK evaluations of selected compounds are described herein.
