This method for producing an aromatic astatine compound comprises reacting an aromatic iodonium ylide with astatine to produce an aromatic astatine compound.

Provided herein are isotopologues of Compound A, which are enriched with isotopes such as, for example, deuterium. Pharmaceutical compositions comprising the isotope-enriched compounds, and methods of using such compounds are also provided.

In a method (100 to 208) in which hyperpolarizable tracer molecules (20, 88 to 98) are hydrogenated and then optionally also hyperpolarized for magnetic resonance imaging, it is provided that, in a first method step (104, 202), a hydrogen solution (10, 12, 4) having a saturation factor of at least 50% be prepared and that the hydrogenation reaction (186 to 190, 206) not be triggered until a subsequent, second method step (106, 204). An apparatus (1) with which the method of the invention (100 to 208) is executable is also provided.

wherein R is a C.sub.6-C.sub.12 substituted or unsubstituted aryl, a C.sub.6-C.sub.12 substituted or unsubstituted heteroaryl, a C.sub.1-C.sub.6 substituted or unsubstituted alkyl or —NR′R′, Q is C(O), O, NR′, S, S(O).sub.2, C(O).sub.2 (CH2)p Y is C(O), O, NR′, S, S(O).sub.2, C(O).sub.2, (CH2)p Z is H or C.sub.1-C.sub.4 alkyl, R′ is H, C(O), S(O).sub.2, C(O).sub.2, a C.sub.6-C.sub.12 substituted or unsubstituted aryl, a C.sub.6-C.sub.12 substituted or unsubstituted heteroaryl or a C.sub.1-C.sub.6 substituted of unsubstituted when substituted, aryl, heteroaryl and alkyl are substituted with halogen, C.sub.6-C.sub.12 heteroaryl, —NR′R′ or COOZ, which have diagnostic and therapeutic properties, such as the treatment and management of prostate cancer and other diseases related to NAALADase inhibition, Radiolabels can be incorporated into the structure through a variety of prosthetic, groups attached at the X amino acid side chain via a carbon or hetero atom linkage.

The present invention provides a set of novel isobaric chemical tags, also referred herein as SUGAR (Isobaric Multiplex Reagents for Carbonyl Containing Compound). These labeling tags are compact and easy to synthesize at high yield and purity in just a few steps using commercially available starting materials. The tagging reagents of the present invention comprise: a) a reporter group, having at least one atom that is optionally isotopically labeled; b) a balancing group, also having at least one atom that is optionally isotopically labeled, and c) an aldehyde, ketone, or carboxylic acid reactive group. The multiplex SUGAR tags are able to react with an aldehyde, ketone, or carboxylic acid group of the molecule to be tagged, which offers the capability for labeling and quantitation of glycans, proteins/peptides, and fatty acids.

The present invention provides a compound of Formula I: wherein R.sup.1 is hydrogen, F, or .sup.18F; and R.sup.2 is hydrogen, F, or .sup.18F; or a pharmaceutically acceptable salt thereof, provided that when R.sup.1 is .sup.18F then R.sup.2 is not .sup.18F, useful as a CGRP receptor antagonist for PET imaging.
