Abstract:
The present invention relates to novel compounds of formula (I) and pharmaceutically acceptable salts thereof, a process for the preparation thereof, as well as pharmaceutical compositions containing them and the use thereof as drugs, particularly for the treatment of infectious diseases.
Abstract:
The present disclosure provides methods for assessing (e.g., measuring, analyzing, detecting, determining, evaluating, and/or estimating) the secondary structure of Glatiramer Acetate (GA) and, in some instances polymeric precursors of GA. The methods entail assessing the fraction of a sample of GA that is in alpha-helical conformation and/or assessing the fraction of a sample of GA that is in random coil conformation.
Abstract:
The invention relates to a method for the synthesis of a compound of the formula (I) in which: n is an integer higher than or equal to 1; Rb and each Rn are independently a hydrogen atom, a C1-C6 arylalkyl group or a C1-C6 alkyl group substituted or not by an aryl group, -COOH, C1-C6 -COO-(alkyl), -CONH2, - SH, heteroaryl, -NH2, -NHC(NH)(NH2), C1-C6 -S-(alkyl), -OH or phenol; Ra is a N-protective group; Rc is a ORd group in which Rd is a C1-C6 alkyl group or a NReRf group in which Re and Rf Re independently an N-protective group.
Abstract:
Novel compounds are provided which are useful as linking groups in chemical synthesis, preferably in the solid phase synthesis of oligonucleotides and polypeptides. These compounds are generally photolabile and comprise protecting groups which can be removed by photolysis to unmask a reactive group. The protecting group has the general formula: Ar-C(R1)(R2)-O-C(O)- wherein: Ar is an optionally substituted fused polycyclic aryl or heteraromatic group or a vinylogous derivative thereof; R1 and R2 are independently H, optionally substituted alkyl, alkenyl or alkynyl, optionally substituted aryl or optionally substituted heteroaromatic, or a vinylogous derivative of the foregoing; and X is a leaving group, a chemical fragment linked to Ar-C(R1)(R2)-O-C(O)- via a heteroatom, or a solid support; provided that when Ar is 1-pyrenyl and R1 and R2 are H, X is not linked to Ar-C(R1)(R2)-O-C(O)- via a nitrogen atom. Preferred embodiments are those in which Ar is a fused polycyclic aromatic hydrocarbon and in which the substituents on Ar, R1 and R2 are electron donating groups. A particularly preferred protecting group is the "PYMOC" protecting group, pyrenylmethyloxycarbonyl, where Ar is pyrenyl and R1 and R2 are H. Also provided is a method of forming, from component molecules, a plurality of compounds on a support, each compound occupying a separate predefined region of the support, using the protected compounds described above.
Abstract:
The present invention is related to a novel and improved process for the manufacture of compounds of formula (I) or salts thereof herein designated as benzylsulfonyl-Ser-X-4-amidinobenzylamide, wherein R is a C 1 to C 6 linear or branched aliphatic hydrocarbon chain optionally substituted with a C 6 to C 10 aromatic group.
Abstract:
Systems and processes for performing solid phase peptide synthesis are generally described. Solid phase peptide synthesis is a known process in which amino acid residues are added to peptides that have been immobilized on a solid support. In certain embodiments, the inventive systems and methods can be used to perform solid phase peptide synthesis quickly while maintaining high yields. Certain embodiments relate to processes and systems that may be used to heat, transport, and/or mix reagents in ways that reduce the amount of time required to perform solid phase peptide synthesis.
