摘要:
The present invention concerns new thiolysine and selenolysine compounds that can be used as building blocks for peptides and proteins, providing ligation handles for site- and chemoselective modification of said peptides and proteins. In particular, the invention provides. In particular, the invention provides (the use of) the compounds 5-thiolysine (also referred to as δ-thiolysine); 4-thiolysine (also referred to as γ-thiolysine); 5-selenolysine (also referred to as δ-selenolysine) and 4-selenolysine (also referred to as γ-selenolysine). The positioning of the thiol or selenol group at the respective carbon atom allows for a very efficient intramolecular transfer reaction to take place after conjugation with a selected ligand, and the thiol or selenol group may subsequently be removed using reported procedures, thereby restoring the native lysine structure, or be used as an additional conjugation handle. The methodology is fast and gives well-defined material.
摘要:
There is provided a compound or the like which can become a material in which many functions are controllable. A first aspect of the present invention lies in an organic semiconductor compound, characterized in that an organic molecule which becomes a donor is formed by being salt-formed with an inorganic acid or an inorganic base and self assembly is accomplished. According to this configuration, there can be obtained an organic semiconductor compound by a simple technique. A second aspect of the present invention lies in an organic compound, characterized in that a compound containing a tetrathiafulvalene affinity region in a framework thereof and having a protic acid functional group is formed by being induced to a salt with ammonia or a salt with hydroxyamine. According to this configuration, there can be obtained an organic compound in which many functions are controllable.
摘要:
Anti-cancer compositions and methods are described including one or more isothiocyanates and/or isoselenocyanates. Methods of treating a subject are provided according to embodiments of the present invention which include administering a therapeutically effective amount of a composition including an isothiocyanate and/or isoselenocyanate to a subject having a condition characterized by Akt dysregulation. Administering a therapeutically effective amount of a composition including an isothiocyanate and/or isoselenocyanate to a subject detectably increases apoptosis and/or decreases proliferation of cancer cells, particularly cancer cells characterized by Akt dysregulation.
摘要:
Provided herein are processes for the production of methionine or selenomethionine from homoserine. In particular, the processes proceed via the production of carbamate intermediates.
