Hydrophilic/hydrophobic patterning is a well-established design strategy to guide secondary structure formation of both natural as well as non-natural oligomers and polymers. This contribution explores the feasibility of a new approach for the synthesis of ...
Water-soluble organic carbon (WSOC) is a ubiquitous and significant fraction of fine particulate matter. Despite advances in aerosol thermodynamic equilibrium models, there is limited understanding on the comprehensive impacts of WSOC on aerosol acidity (p ...
Our reliance on fossil fuels, which is unsustainable due to dwindling reserves, has led to various environmental issues. Lignocellulosic biomass could serve as a renewable source of carbon and energy for the production of fuels and chemicals. While several ...
The G protein-coupled receptor TGR5 has been identified as an important component of the bile acid signaling network, and its activation has been linked to enhanced energy expenditure and improved glycemic control. Here, we demonstrate that activation of T ...
N-(Fluoro-3-methoxyacryloyl)anilines [2-fluoro-3-methoxy-2-propenanilides] can be prepd. by condensation between lithium anilides and Me 2-fluoro-3-methoxy-2-propenoate. For example, the reaction of (E)- and (Z)-2-fluoro-3-methoxy-2-propenoic acid Me ester ...
Serine, threonine-derived (4S)-oxazolidine-4-carboxylic acid, and cysteine-derived (4R)-thiazolidinecarboxylic acid, denoted pseudo-proline (Xaa[Psi(R1,R2)pro]), serve as structure disrupting, solubilizing building blocks in peptide synthesis. Variation of ...
Hapalosin I (R1 = Me, R2 = OH), a 12-membered cyclic depsipeptide possessing MDR-reversing activity, and its analogs, N-desmethylhapalosin I (R1 = H, R2 = OH) and 8-deoxyhapalosin I (R1 = Me, R2 = H), have been synthesized using macrolactamization as an im ...
The preparation of synthetic polymers with exact control over chain length and monomer sequence is one of the long-standing challenges in polymer science. Nature perfectly masters the synthesis of high molecular weight, perfectly monodisperse polypeptides ...
In the framework of the design and development of TGR5 agonists, we reported that the introduction of a C(23)(S)-methyl group in the side chain of bile acids such as chenodeoxycholic acid (CDCA) and 6-ethylchenodeoxycholic acid (6-ECDCA, INT-747) affords s ...
The basic aqueous coordination chemistry of Ru-II has been studied using the catalytically important TPPTS phosphine (TPPTS = trisodium salt of 3,3 ',3 ''-phosphinetriylbenzenesulfonic acid) and small gas molecules (H-2, CO, N-2) as ligands. As a result, n ...
