18F-labeling of 5-(trifluoromethyl)-dibenzothiophenium trifluoromethanesulfonate, commonly referred to as the Umemoto reagent, has been accomplished applying a halogen exchange 18F-fluorination with 18F-fluoride, followed by oxidative cyclization with Oxone and trifluoromethanesulfonic anhydride. This new 18F-reagent allows for the direct chemoselective 18F-labeling of unmodified peptides at the thiol cysteine

The present invention relates to process for identifying a compound which induces the mitochondrial permeability transition (MPT) in proliferating cells, wherein said process comprises contacting a cell or cell extract with a compound, determining whether compound binds to adenine nucleotide translocator (ANT), and determining whether the compound selectively induces the MPT in proliferating cells.
A PSMA-specific imaging agent comprising a compound according to formula I:
are described, wherein S1 is an organic spacer group having from 5 to 30 carbons, A is an amino acid forming a portion of a negatively charged peptide oligomer, n is from 3 to 6, S2 is an organic spacer group having from 5 to 15 carbons, and I is an imaging group, and pharmaceutically acceptable salts thereof. The PSMA-specific imaging agents can be used to image PSMA within a tissue region to guide the treatment of diseases such as prostate cancer.
