    摘要: A composition comprising an aqueous solution of: a wet-etch formulation that is proven to etch copper; and a wetting agent. Exemplary wet-etch formulations include a mixture of a strong inorganic acid, such as sulfuric acid or hydrofluoric acid, and an oxidizing agent such as hydrogen peroxide, and further include ammonium persulfate. Exemplary wetting agents include organic acids such as citric acid, acetic acid, oxalic acid, or formic acid. Processes of using the compositions for wet-etching, or chemical mechanical polishing, or fabricating thick copper inductors, are further provided.

    摘要: The invention provides a composition of matter of formula I V-L-R   (I) where V is an organic group having binding affinity for an angiotensin II receptor site, L is a linker moiety or a bond, and R is a moiety detectable in in vivo imaging of a human or animal body, with the provisos that where V is angiotensin or a peptidic angiotensin derivative or analog then V-L-R is other than a non-metal radionuclide substituted peptide (eg 125I substituted angiotensin II) and L-V is other than simply a peptide with a chelating agent amide bonded to a side chain thereof. This composition of matter may be used to image cardiovascular diseases and disorders.

    摘要: The present invention relates to methods and reagents for [18F]-fluorination, particularly of peptides. The resultant 18F-labelled compounds are useful as radiopharmaceuticals, specifically for use in Positron Emission Tomography (PET). Thus, a compound of formula 18F-(Linker)-SH, such as a compound of formula (IV), (V), or (VI): 18F—(CH2CH2O)n—(CH2)m—SH   (IV) 18F—(CH2)p—SH   (V) may be reacted with an activated peptide as a means for 18F-labelling.

    摘要: The synthesis of peptides comprising disulphide bridges is challenging since it is difficult to ensure that the correct cysteine residues combine to form the desired disulphide bridges. The present invention describes novel protection techniques useful in the preparation of peptides. Described is a process for the deprotection of an Acm-, MBzl- and/or tBu-protected thiol which comprises reacting said protected thiol with an acid in the presence of an oxidising agent at a temperature sufficient to effect deprotection and generation of disulphide bonds.
