Abstract
As part of a medicinal chemistry program aimed at discovering a mineralocorticoid receptor modulator for treatment of kidney and cardiovascular indications, multiple labeled versions of the lead compound, balcinrenone (AZD9977), were prepared. Four stable isotope labeled versions of the compound were prepared for clinical bioanalysis and biological investigations. Three of these stable isotope labeled compounds were tritiated as well as the parent for biology applications and DMPK investigations. They were prepared using a standard iodination-tritiodehalogentation approach. Finally, AZD9977 was prepared in carbon-14 labeled form for preclinical and clinical applications.

Abstract
Antibody drug conjugates (ADCs) are one of the most promising technologies to treat cancer as they combine the specificity of an antibody with the high potency of a cytotoxic molecule such as tomaymycin derivatives, which are DNA-interactive antitumor antibiotics previously isolated from bacterial broth. The multistep chemical synthesis of some tomaymycin derivatives is complicated because their structures contain a reactive imine bond. Therefore, we turned to biosynthesis to obtain 14 C radiolabelled tomaymycin derivative to support ADME studies. Following Hurley's work (J. Antibiotics 1977, 30, 349-370; Antimicrob. Agents Chemother. 1979, 15, 42-45; Acc. Chem. Res. 1980, 13, 263-269), the 14 C radiolabel was incorporated efficiently in one step from radiolabelled tyrosine using the strain Streptomyces sp. FH6421. This process has been further optimized by using anthranilic acid as radiolabelled precursor, leading to one of the highest incorporation levels of radiochemical precursors published to date. This biosynthetic strategy is the fastest way to access such radiolabelled precursors.

Preparation of Carbon-14 Labeled 2-(2-mercaptoacetamido)-3-phenylpropanoic Acid as Metallo-beta-lactamases Inhibitor (MBLI), for Coadministration with Beta-lactam Antibiotics. Curr Org Synth 2019; 16:765-771. [DOI: 10.2174/1570179416666190423114704] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2018] [Revised: 02/08/2019] [Accepted: 03/11/2019] [Indexed: 01/21/2023]
Abstract
Aim and Objective:
Bacteria could become resistant to β-lactam antibiotics through production of β-
lactamase enzymes like metallo-β-lactamase. 2-(2-mercaptoacetamido)-3-phenylpropanoic acid was reported
as a model inhibitor for this enzyme. In order to elucidate the mechanism of action in the body’s internal
environment, preparation of a labeled version of 2-(2-mercaptoacetamido)-3-phenylpropanoic acid finds
importance. In this regard, we report a convenient synthetic pathway for preparation of carbon-14 labeled 2-(2-
mercaptoacetamido)-3-phenylpropanoic acid.
Materials and Methods:
This study was initiated by using non-radioactive materials. Then, necessary
characterization was performed after each of the reactions. Finally, the synthesis steps were continued to
produce the target labeled product. For labeled products, the process was started from benzoic acid-[carboxyl-
14C] which has been prepared from barium 14C-carbonate. Chromatography column and NMR spectroscopy
were used for purifications and identification of desired products, respectively. Barium [14C]carbonate was
purchased from Amersham Pharmacia Biotech and was converted to [14C]benzyl bromide. Radioactivity was
determined using liquid scintillation spectrometer.
Results:
We used [14C]PhCH2Br which was previously prepared from [14C]BaCO3, H2SO4, PhMgI, LAH and
HBr, respectively. To neutralize the [14C]phenylalanine in acidic condition and to reach an isoelectric point of
phenylalanine (pH = 5.48), Pb(OH)2 was used. Next, thioacetic acid and bromo acetic acid were used to
prepare (acetylthio) acetic acid. A peptide coupling reagent was used in this stage to facilitating amide bond
formation reaction between [14C]methyl-2-amino-3-phenyl propanoate hydrochloride and (acetylthio) acetic
acid.
Conclusion:
Carbon-14 labeled 2-(2-mercaptoacetamido)-3-phenylpropanoic acid via radioactive
phenylalanine was obtained with overall chemical yield 73% and radioactivity 65.3 nCi. The labeled target
product will be used for in vivo pharmacological studies.

Abstract
In this review, newly developed cyanation methods are evaluated in regards to their usefulness in synthetic isotope chemistry. In combination with already established protocols in 13/14 C- or 11 C-isotope chemistry, this manuscript should help isotope scientists to choose the best possible method for their scientific cyanation problem, but with the main focus on 14 C-applications. Perhaps, most promising of the described novel cyanation reaction is the decarboxylation-cyanation-hydrolysis approach which makes a 1-step late-stage functionalization procedure possible.

Abstract
The palladium-catalyzed cyanation of Ar-X (X = I, Br, Cl, OTf, and H) allows for an efficient access towards benzonitriles. After its discovery in 1973 and following significant improvements in recent decades, this methodology has become nowadays the most popular for preparation of substituted aromatic nitriles. In this critical review, we summarize the important developments in this area from 2000 until 2010 (151 references).

Abstract
Epidermal growth factor receptors (EGFR), upregulated in many tumor types, have been a target for therapeutic development and molecular imaging. The objective of this study was to evaluate the distribution and metabolic characteristics of fluorine-18 labeled anilinoquinazolines as potential imaging agents for EGFR tyrosine kinase expression. Fluorine-18 labeled fluoronitrobenzenes were prepared by reaction of potassium cryptand [(18)F]fluoride with 1,2- and 1,4-dinitrobenzenes, and 3-nitro-N,N,N-trimethylanilinium triflate in 5min. Decay-corrected radiochemical yields of [(18)F]fluoride incorporation into the nitro-aromatic compounds were 81±2%, 44±4% and 77±5% (n=3-5) for the 2-, 3- and 4-fluoro isomers, respectively. Sodium borohydride reduction to the corresponding [(18)F]fluoroanilines was achieved with greater than 80% conversion in 5min. Coupling of [(18)F]fluoroaniline-hydrochlorides to 6,7-dimethoxy-4-chloro-quinazoline gave the corresponding 6,7-dimethoxy-4-(2-, 3- and 4-[(18)F]fluoroanilino)quinazolines in 31±5%, 17±2% and 55±2% radiochemical yield, respectively, while coupling to the 6,7-diethoxy-4-chloro-quinazoline produced 6,7-diethoxy-4-(2-, 3- and 4-[(18)F]fluoroanilino)quinazolines in 19±6%, 9±3% and 36±6% radiochemical yield, respectively, in 90min to end of synthesis from [(18)F]fluoride. Biodistribution of 2- and 4-[(18)F]fluoroanilinoquinazolines was conducted in tumor-bearing mice (MDA-MB-435 and MDA-MB-468 xenografts). Low tumor uptake (<1% injected dose per gram (ID/g) of tissue up to 3h postinjection of the radiotracers) was observed. High bone uptake (5-15% ID/g) was noted with the 4-[(18)F]fluoroanilinoquinazolines. The metabolic stabilities of radiolabeled quinazolines were further evaluated by incubation with human female cryopreserved isolated hepatocytes. Rapid degeneration of the 4-fluoro-substituted compounds to baseline polar metabolites was observed by radio-TLC, whereas, the 2- and 3-[(18)F]fluoroaniline derivatives were significantly more stable, up to 2h, corroborating the in vivo biodistribution studies. para-Substituted [(18)F]fluoroanilines, a common structural motif in radiopharmaceuticals, are highly susceptible to metabolic degradation.
