摘要:
Novel acetylamino benzoic acid compounds, methods of using and pharmaceutical compositions comprising an acetylamino benzoic acid derivative are disclosed. The methods include methods of treating or preventing a disease ameliorated by modulation of premature translation termination or nonsense-mediated mRNA decay, or ameliorating one or more symptoms associated therewith.
摘要:
Provided is a method for characterising a polypeptide or a population of polypeptides, which method comprises the steps of: (a) contacting a sample comprising one or more polypeptides with a lysine reactive agent to cap ε-amino groups; (b) optionally reacting the sample of polypeptides with an amine reactive reagent to block α-amino groups; (c) digesting the sample of polypeptides with a cleavage reagent to produce peptide fragments; (d) optionally deactivating the cleavage reagent; (e) removing those peptides having uncapped or unblocked amino groups; and (f) recovering the N-terminal peptides.
摘要:
The invention provides a chemical construct for use in solid phase synthesis comprising a solid support Q having linked thereto via a connecting group Y a substrate R; the connecting group Y having first and second cleavage sites which are orthogonally and selectively cleavable; the second cleavage site being selectively cleavable to release the substrate; and the first cleavage site being located at a position between the second cleavage site and the solid support and being selectively cleavable to release a fragment Fr comprising the substrate and at least a portion of the connecting group Y; characterised in that cleavage at the first cleavage site forms or introduces on the chemical fragment Fr at the first cleavage site a moiety comprising a sensitising group G (such as an amino group) which sensitises the chemical fragment Fr to instrumental, e.g. mass spectroscopic, analysis. Also provided are methods of analysis employing the constructs, as well as intermediate constructs.

摘要:
Phenylalanine derivatives of the following formula and analogues thereof have an antagonistic activity to α 4 β 7 integrin and a selectivity toward α 4 β 1 integrin. They are used as therapeutic agents for various diseases to which α 4 β 7 integrin relates.
摘要:
Disclosed are compounds which are inhibitors of metalloproteases and which are effective in treating conditions characterized by excess activity of these enzymes. In particular, the compounds have a structure according to formula (I): where J, M, Q, T, W, X, Z, R?1, R2, R3, R4, R4', R5, R6, R6', R7¿, m, and n have the meanings described in the specification. This invention also includes optical isomers, diastereomers and enantiomers of the formula above, and pharmaceutically-acceptable salts, biohydrolyzable amides, esters, and imides thereof. Also disclosed are pharmaceutical compositions comprising these compounds, and methods of treating or preventing metalloprotease-related maladies using the compounds or the pharmaceutical compositions.
摘要:
Facile methods for preparing diketide and triketide thioesters are disclosed. The resulting thioesters may be used as intermediates in the synthesis of desired polyketides, and may contain functional groups which ultimately reside in side chains on the resulting polyketide and thus can be used further to manipulate the polyketide so as to form derivatives. The polyketides produced may also be tailored by glycosylation, hydroxylation and the like. New polyketides and their derivatives and tailored forms are thereby produced.
摘要:
