  Deleterious effect of 7-methyl group on glycosylation of 2-naphthols

  摘要：

  C-Glycosylations of several 2-naphthols with different glycosyl donors have been investigated in the pursuit of the total synthesis of mayamycin (I). While glycosylations of the parent 2-naphthol are readily achievable, those of 5-methoxy-7-methyl-2-naphthol (6) embodying the target are ineffective under different Lewis acidic conditions. The inefficiency of the glycosylation of 6 has been attributed to the steric effect exerted by C7 methyl group, which was corroborated by glycosylation studies of different 2-naphthols.

  Identification of Fused-Ring Alkanoic Acids with Improved Pharmacokinetic Profiles that Act as G Protein-Coupled Receptor 40/Free Fatty Acid Receptor 1 Agonists

  摘要：

  The G protein-coupled receptor 40 (GPR40)/free fatty acid receptor 1 (FFA1) has emerged as an attractive target for a novel insulin secretagogue with glucose dependency. We previously identified phenylpropanoic acid derivative 1 (3-{4-[(2',6'-dimethylbiphenyl-3-yl)methoxy]-2-fluorophenyl}propanoic acid) as a potent and orally available GPR40/FFA1 agonist; however, 1 exhibited high clearance and low oral bioavailability, which was likely due to its susceptibility to beta-oxidation at the phenylpropanoic acid moiety. To identify long-acting compounds, we attempted to block the metabolically labile sites at the phenylpropanoic acid moiety by introducing a fused-ring structure. Various fused-ring alkanoic acids with potent GPR40/FFA1 activities and good PK profiles were produced. Further optimizations of the lipophilic portion and the acidic moiety led to the discovery of dihydrobenzofuran derivative 53 ((6-{[4'-(2-ethoxyethoxy)-2',6'-dimethylbiphenyl-3-yl]methoxy}-2,3-dihydro-1-benzofuran-3-yl)acetic acid), which acted as a GPR40/FFA1 agonist with in vivo efficacy during an oral glucose tolerance test (OGTT) in rats with impaired glucose tolerance.

  cofactor. The generated systems catalyze the insertion of carbenes into the C-H bonds of a range of phthalan derivatives containing substituents that render the two methylene positions in each phthalan inequivalent. These reactions occur with site-selectivity ratios of up to 17.8:1 and, in most cases, with pairs of enzyme mutants that preferentially form each of the two constitutional isomers. This
