摘要:
The invention relates to a novel agent in the form of rhodanine derivatives, which has prophylactic, antiproliferative and antimetastatic activity. Said agent can find use in medicine and pharmacology for the prophylaxis and/or treatment of neoplastic diseases of variable localisation.
摘要:
Isothiocyanates are formed by oxidizing, with gaseous oxygen or air, in the presence of a metal oxidation catalyst a dithiocarbamate with appropriate control of the pH of the reaction medium to suppress the formation of by-products. Optionally a quaternary ammonium halide catalyst can be used to increase product yield.

摘要:
The present invention relates to modification of isotope ratios in peptides and polypeptides as an alternative to full isotopic exchange for coding in proteomics. Subtle modification of isotope ratio does not compromise protein identification experiments and can thus provide elemental composition data for accurate isotope ratio decoding. Application of subtle modification of isotope ratio proteomics (SMIRP) offers a convenient approach to in vivo isotope coding.
摘要:
The present invention provides methods and reagents for sequencing amino acids. One embodiment of the method for determining the terminal amino acid of a substantially pure polypeptide comprises the steps of (a) attaching the polypeptide to a solid support, (b) reacting the polypeptide with a compound described below, under conditions and for a time sufficient for coupling to occur between the terminal amino acid of the polypeptide and the compound, thereby yielding a polypeptide with a derivatized terminal amino acid, (c) washing the solid support to remove unbound material, (d) cleaving the derivatized terminal amino acid from the polypeptide with a cleaving agent, (e) ionizing the cleaved derivatized terminal amino acid, and (f) determining the molecular weight of the derivatized terminal amino acid, such that the terminal amino acid is determined. Within one embodiment, the compound is p-isothiocyanato phenethyl trimethylammonium and counterion salts thereof.
