Androgens play a crucial role in prostate cancer progression, and trans-1-amino-3-[(18)F]fluorocyclobutanecarboxylic acid (anti-[(18) F]FACBC) are used for visualization of prostate cancer. We examined the effect of androgen on the expression of amino acid transporters related to anti-[(18)F]FACBC transport and uptake of trans-1-amino-3-fluoro-[1-(14)C]cyclobutanecarboxylic acid (anti-[(14)C]FACBC). Expression of amino acid transporters and uptake ...

Amorphous silica and crystalline silicalite (MFI structure) are demonstrated to be active and environmentally benign catalysts for propionic acid ketonisation at 450-500 °C to form 3-pentanone. The silicalite is particularly efficient, and its ketonisation selectivity is increased by base modification probably through generation of silanol nests.

Suzuki-Miyaura cross-coupling has been used to couple novel carbohydrate-based boronic acids, site-selectively, to the surface of E. coli at an unnatural amino acid. In this way, benign metal-catalyzed cellular switching allowed modulation of interactions with biomolecular partners via prokaryotic O-glycosylation mimics.

Disproportionation of TEMPO in acids leads to the formation of an N-oxoammonium salt, which can further decompose under thermal conditions, yielding the corresponding hydroxylamine, N(2)O, CO(2) and a series of dimerisation products. Overall, acid-catalysed thermal decay of TEMPO leads to ca. 80% yield of hydroxylamine.
