Synthesis and monkey-PET study of (R)- and (S)-18F-labeled 2-arylbenzoheterocyclic derivatives as amyloid probes with distinctive in vivo kinetics

This study describes an effective strategy to improve pharmacokinetics of Abeta imaging agents, offering a novel class of (R)- and (S)-18F-labeled 2-arylbenzoheterocyclic derivatives which bear an additional chiral hydroxyl group on the side chain. These ligands displayed binding abilities toward Abeta aggregates with Ki values ranging from 3.2 to 195.6 nM. Chirality-related discrepancy was observed in biodistribution, and (S)-2-phenylbenzoxazole enantiomers exhibited vastly improved brain clearance with washout ratios higher than 20. Notably, (S)-[18F]28 possessed high binding potency (Ki = 7.6 nM) and exceptional brain kinetics (9.46% ID/g at 2 min, brain2min/brain60min = 27.8) that is superior to well-established [18F]AV45. The excellent pharmacokinetics and low nonspecific binding of (S)-[18F]28 were testified by dynamic PET/CT scans in monkey brains. In addition, (S)-[18F]28 clearly labeled Abeta plaques both in vitro and ex vivo. These results might qualify (S)-[18F]28 to detect Abeta plaques with high signal-to-noise ratio.

Optimization of GPR40 agonists for type 2 diabetes

GPR40 (FFA1 and FFAR1) has gained significant interest as a target for the treatment of type 2 diabetes. TAK-875 (1), a GPR40 agonist, lowered hemoglobin A1c (HbA1c) and lowered both postprandial and fasting blood glucose levels in type 2 diabetic patients in phase II clinical trials. We optimized phenylpropanoic acid derivatives as GPR40 agonists and identified AMG 837 (2) as a clinical candidate. Here we report our efforts in searching for structurally distinct back-ups for AMG 837. These efforts led to the identification of more polar GPR40 agonists, such as AM-4668 (10), that have improved potency, excellent pharmacokinetic properties across species, and minimum central nervous system (CNS) penetration.

Synthesis of 2-Arylbenzothiazole and 2-Arylthiazole Derivatives via a Ru-Catalyzed meta-Selective C-H Nitration Reaction

A Ru-catalyzed meta-selective C-H nitration of 2-arylbenzothiazoles and 2-arylthiazoles has been developed. A wide range of functional groups are tolerated, providing the meta-nitrated products in good to excellent yields using Cu(NO3)2·3H2O as the nitro source. The nitration could be carried out on a gram scale and used for the synthesis of promising therapeutic leads for human African trypanosomiasis.

Synthesis and pharmacological screening of novel (2-(4-Methyl-2-oxo-2H- chromen-7-yloxy)-N-(benzo[d]thiazol-2-yl))acetamide derivatives

A new series of 2-(4-methyl-2-oxo-2H-chromen-7-yloxy)-N-(benzo[d]thiazol-2- yl)acetamide derivatives (4a-k) was synthesized and evaluated for their D 2 and 5HT2 antagonistic activity as a measure of atypical antipsychotic property. Compounds (4a-k) were synthesized by refluxing various N-(benzothiazol-2-yl)-2-chloroacetamides substituted derivatives (3a-k) with 7-hydroxy-4 methyl-2H-chromen-2-one (1) in acetonitrile and anhydrous K 2CO3. N-(Benzothiazol-2-yl)-2-chloroacetamides substituted derivatives (3a-k) were prepared from the chloroacetyl chloride with various 2-amino benzothiazole substituted derivatives (2a-k). The synthesized compounds were characterized with the help of spectral and analytical data. Most of these compounds showed dopamine D2 receptor antagonistic activity from moderate to high affinity along with serotonin 5-HT2 receptor blockage activity: a property that has been suggested as necessary for atypicality. The D 2 and 5-HT2 receptor blockage activity was evaluated by inhibition of apomorphine-induced climbing behaviour and 5HTP induced head twitches in mice, respectively.

Amino acid derivatives in organic synthesis, Part 4 [1]: Facile synthesis of heterocycles containing a glycine residue

Pyridines, thiazolopyridines and pyrazolopyrans containing glycinate residue were prepared by reacting N-cyanoacryloglycinate ylidenes with active methylene compounds via a Michael addition – intracyclization synthetic pathway. Simple routes for the synthesis of heterocycles with an amino acid residue were previously reported [1-3] as the incorportation of these residues improves the pharmacokinetics and toxicity of active compounds [4,5]. However, trials to deesterify these residues for coupling purposes were unsuccessful. So, we tried herein new approaches for synthesizing heterocyles carrying one or two glycine moieties with free carboxylic acid group to facilitate further peptide linkage [6] on one hand and on the other one could be able to form metal chelates, a property having a significant output on the toxicological behaviour [7].

Pharmacological profile of 6,12-dihydro-3-methoxy-1-benzopyrano[3,4-b] [1,4]benzothiazin-6-one, a novel human estrogen receptor agonist

Pharmacological studies were carried out to characterize further the endocrinological profile and the binding mode to the estrogen receptor (ER) of 6,12-dihydro-3-methoxy-l-benzopyrano[3,4-b][1,4]benzothiazin-6-one (1). Binding experiments were conducted with highly purified recombinant human estrogen receptors hERalpha and beta. Potent estrogenic activity of compound 1 was assessed by testing its ability to down-regulate ERs and to enhance estrogen receptor element (ERE)-dependent transcription. The latest step of our work dealt with the synthesis of the 9-fluorinated derivative 15 for ionic microscopy experiments to determine the intracellular localization of compound 1. Although 1 failed to compete with [3H]E2 for binding to both ER isoforms, evidence was reported that it interacted with hERalpha in MCF-7 cells (ER down-regulation/ERE-dependent luciferase induction). Hence, an appropriate conformation of the hormone binding domain, most probably conferred by co-regulators of ER, is required for the onset of an activity of the compound 1. Estrogenic activity was weak but on the order of magnitude of that of coumestrol (slightly weaker). The synthesis of the 9-methoxylated derivative 16 and its pharmacological evaluation led us to propose a binding mode of 1 on hERalpha. Compound 1 appears to interact with ERalpha mainly through interactions of its 3-methoxy substituent with the residue His-524 of the hormone binding domain.

2-amino-4-arylthiazole derivatives as anti-giardial agents: Synthesis, biological evaluation and QSAR studies

A series of seven 2-amino-4-arylthiazoles were prepared following Hantzsch’s modified method under microwave irradiation. A set of 50 derivatives was obtained and the in vitro activity against Giardia intestinalis was evaluated. The results on the biological activity revealed that, in general, the N-(5-bromo-4-aryl-thiazol-2-yl)-acetamide scaffold showed high bioactivity. In particular, compounds 6e (IC50= 0.39 muM) and 6b (IC50= 0.87 muM) were found to be more potent than the positive control metronidazole. Citoxicity and acute toxicity tests performed showed low toxicity and high selectivity of the most active compounds (6e SI = 139, 6b SI = 52.3). A QSAR analysis was applied to a data set of 37 obtained 2-amino-4-arylthiazoles derivatives and the best model described a strongly correlation between the anti-giardiasic activity and molecular descriptors as E2M, RDF115m, F10, MATS6v, and Hypnotic-80, with high statistical quality. This finding indicates that N-substituted aminothiazole scaffold should be investigated for the development of highly selective anti-giardial agent.
