摘要:The invention provides an amphiphilic coating for the direct and rapid synthesis of an array of peptides and small molecular compounds on a planar surface of a solid support, comprising a hydrophilic chemical structure and a lipophilic group, wherein said peptides and small molecular compounds differ from spot to spot from each other in the chemical structure, characterized in that said amphiphilic coating possesses low wettability to polar aprotic solvents used in the array synthesis; said amphiphilic coating possessing low wettability is designed that it can be converted to a coating possessing high wettability by hydrolysis of the lipophilic group; and said amphiphilic coating comprises an amino group for the reaction with an electrophilic reagent. The invention further provides a solid support comprising said amphiphilic coating and a method for method for the direct and rapid synthesis of an array of peptides and small molecular compounds on a planar surface of a solid support, wherein said planar surface of a solid support comprises said amphiphilic coating. Said method includes the enhancing of the wettability of a glass surface to organic solvents to realize automated on-demand biomolecular array synthesis comprising both, peptides and small molecular compounds. The amphiphilic surface can be switched to a hydrophilic surface, resulting in high density arrays suitable for protein- and cell-based screening.

摘要:A synthetic resin based on a polystyrene that can be used as a support for solid phase peptide synthesis and that has been cross-linked with from 0 to 5 mol % of divinyl benzene, characterized in that it has been substituted at benzene rings of its skeletal structure by groups of the formula ##STR1## in which X represents --O-- or --NH-- and R represents C 1 -C 4 -alkyl, as a support renders possible the solid phase synthesis of peptides and peptide amides that are, if desired, protected at the N-terminal and/or at other functional groups. The resin is manufactured by reaction of a customary chloromethylated polystyrene resin with an alkali metal salt of the corresponding 4-hydroxybenzophenone and subsequent reduction of the carbonyl group and, optionally, amination.

摘要:The compound DMX-5804, IUPAC name 5-(4-(2-methoxyethoxy)phenyl)-7-phenyl-3,4a,7,7a-tetrahydro-4H-pyrrolo[2,3-d]pyrimidin-4-one, is a potent and selective inhibitor of mitogen-activated protein kinase kinase kinase kinase-4 (MAP4K4). The present disclosure describes a scalable and practical synthesis process for making DMX-5804. The process (1) doesn't rely on transition metals, (2) has reduced duration of reactions, (3) is streamlined with significantly improved yields using low cost raw materials, (4) includes no microwave-assisted reactions, (5) does not require column purification, and (6) generally results in crystalized products having over a 95% purity in each step. The present disclosure also describes DMX-5804 analogs and derivatives for use in inhibiting MAP4K4, and scalable and practical processes for making such DMX-5804 analogs.

摘要:α-Azido Esters By Mitsunobu Reaction With Hn3. Optimization Of This Reaction Was Shown To Proceed At Room Temperature With High Chemical Yield Using 1,1-(Azodicarbonyl)Dipiperidine (Addp) And Trimethylphosphine (Pme3). Complete Inversion Of Configuration Was Observed At The α-Carbon. Several α,α-Disubstituted Amino Acids Were Synthesized In High Overall Chemical Yield And Optical Purity.
