摘要:
Contrast agents comprising microbubble-generating carbohydrate microparticles having a surfactant admixed within the microparticulate structure, with the proviso that the surfactant is not a C10-20 fatty acid, are disclosed. Processes for preparing contrast agents also are disclosed.
摘要:
This invention relates to a set of aqueous marker compositions, each composition having a selected 1/Ti value which is substantially invariant over an at least 10null C. temperature range between 15 and 40null C. and preferably over an at least null2% magnetic field strength range about a selected field strength value between 0.01 and 5T and comprising an aqueous matrix material having a non-zero 1/Ti temperature dependence within said temperature range with distributed therein a first paramagnetic material having a Ti relaxivity which is substantially invariant within said range(s) and/or a second paramagnetic material having within said ranges(s) and T1 relaxivity which has a non-zero temperature dependence of opposite polarity to the temperature dependence of 1/Ti of said matrix material, said set containing a plurality of said compositions with different selected 1/Ti values preferably encompassing at least the range 1.0 to 2.5 snull1, said set preferably comprising at least one said composition containing said second paramagnetic material and at least one said composition containing said first paramagnetic material, where i in Ti is 1 or 2.
摘要:
The invention provides a composition of matter of the formula (I): VnullLnullR 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 VnullLnullR is other than a non-metal radionuclide substituted peptide (e.g. 125I substituted angiotensin II) and LnullV 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 provides a method of contrast enhanced ultrasonic diagnostic imaging comprising administering to a subject a contrast enhancing amount of spheres or particles comprising a matrix enclosing a contrast agent which reflects sound waves, and generating an ultrasonic image of said subject wherein the matrix comprises a polymer held together by chemical bonds and wherein the polymer is selected from the group consisting of acrylates, polystyrene and derivatives thereof.
摘要:
The invention relates to the use of certain chelating agents and their metal chelates and to the use of certain manganese containing compounds, in particular manganese chelates, in the manufacture of a therapeutic agent for use in reducing the cardiotoxicity of an antitumor agent. Such compounds are particularly effective in reducing the side-effects of anthracycline drugs and/or paclitaxel.
摘要:
The invention provides a process by which ultra low salt content triiodinated aromatic compounds may be isolated from a highly acidic hot triiodination raction medium in a straightforward fashion. The process involves increasing the pH to above 5 with sodium hydroxide, addition of sodium bisulphite and/or sodium dithionite, addition of seed crystals, cooling slowly, and washing the collected precipitate with water.
摘要:
This invention relates to a method of electron spin resonance enhanced magnetic resonance imaging which relies on ex vivo dynamic nuclear polarisation of an MR imaging agent.
摘要:
The present invention relates to disulphide-cyclo-�H-Cys-Glu-Gln-Tyr-Cys-OH! and salts thereof which are useful in the treatment of blood clotting disorders.
摘要:
The invention provides iodinated bis phenyl compounds, useful as X-ray contrast agents, of formula (I) (wherein each C.sub.6 R.sub.5 moiety may be the same or different; each denotes a hydrogen or iodine atom or a group M, two or three non-adjacent R groups on each C.sub.6 R.sub.5 moiety denoting iodine atoms and one, two or three R groups on each C.sub.6 R.sub.5 moiety denoting M groups; X denotes a group providing a 1, 2 or 3 atom chain linking the two C.sub.6 R.sub.5 groups, preferably where X is or contains in the bridging chain a carbonyloxy group each C.sub.6 R.sub.5 group being a triodophenyl group or a group in which each R is other than hydrogen; and each M is independently a non-ionic hydrophilic moiety, M preferably being a non-ionic hydrophilic moiety comprising a monohydroxy- or polyhydroxy-alkyl group) and isomers, especially stereoisomers and rotamers, thereof. ##STR1##
