The Significance of Chirality in Drug Design and Synthesis of Bitopic Ligands as D3 Receptor (D3R) Selective Agonists

Because of the large degree of homology among dopamine D2-like receptors, discovering ligands capable of discriminating between the D2, D3, and D4 receptor subtypes remains a significant challenge. Previous work has exemplified the use of bitopic ligands as a powerful strategy in achieving subtype selectivity for agonists and antagonists alike. Inspired by the potential for chemical modification of the D3 preferential agonists (+)-PD128,907 (1) and PF592,379 (2), we synthesized bitopic structures to further improve their D3R selectivity. We found that the (2S,5S) conformation of scaffold 2 resulted in a privileged architecture with increased affinity and selectivity for the D3R. In addition, a cyclopropyl moiety incorporated into the linker and full resolution of the chiral centers resulted in lead compound 53 and eutomer 53a that demonstrate significantly higher D3R binding selectivities than the reference compounds. Moreover, the favorable metabolic stability in rat liver microsomes supports future studies in in vivo models of dopamine system dysregulation.

Substituted 2-[(4-aminomethyl)phenoxy]-2-methylpropionic acid PPARalpha agonists. 1. Discovery of a novel series of potent HDLc raising agents

The peroxisome proliferator activated receptors PPARalpha, PPARgamma, and PPARdelta are ligand-activated transcription factors that play a key role in lipid homeostasis. The fibrates raise circulating levels of high-density lipoprotein cholesterol and lower levels of triglycerides in part through their activity as PPARalpha agonists; however, the low potency and restricted selectivity of the fibrates may limit their efficacy, and it would be desirable to develop more potent and selective PPARalpha agonists. Modification of the selective PPARdelta agonist 1 (GW501516) so as to incorporate the 2-aryl-2-methylpropionic acid group of the fibrates led to a marked shift in potency and selectivity toward PPARalpha agonism. Optimization of the series gave 25a, which shows EC50 = 4 nM on PPARalpha and at least 500-fold selectivity versus PPARgamma and PPARgamma. Compound 25a (GW590735) has been progressed to clinical trials for the treatment of diseases of lipid imbalance.

A Mechanistic Study on the Reaction of Iminothiadiazolidines with Activated Acetylenes: Competitive Pathway through Hypervalent Sulfurane and Zwitterion

The reaction of 3-aryl-5-benzoyl-2-imino-2,3-dihydro-1,3,4-thiadiazoles (6) with dimethyl acetylenedicarboxylate (4b) gave the correspinding thiazole (8) and benzoyl cyanide through sulfurane (B) by 1,3-dipolar cycloaddition and cis-(9) and trans-vinyl (10) compounds through zwitterion (C) by simple addition.Two types of addition reactions competed each other and the ratio of the two depended solely on the solvent polarity (Rtau).Dibenoylacetylene behaved similarly.Several iminothiazolines iminithiadiazolidines reacted with activated acetylenes and the selectivity for the two types of addition reactions for each system was shown to be affected by quite subtle balance of electron-withdrawing ability of each heterocycle.

Synthesis, physicochemical characterization, cytotoxicity, antimicrobial, anti-inflammatory and psychotropic activity of new N-[1,3-(benzo)thiazol-2-yl]- omega-[3,4-dihydroisoquinolin-2(1H)-yl]alkanamides

A series of new N-[(benzo)thiazol-2-yl]-2/3-[3,4-dihydroisoquinolin-2(1H)- yl]ethan/propanamide derivatives was synthesized and characterized by 1H, 13C NMR and IR spectroscopy and mass-spectrometry. A single crystal X-ray study of N-(1,3-benzothiazol-2-yl)-2-[3,4- dihydroisoquinolin-2(1H)-yl]ethanamide is reported to determine its conformational feature. The investigated compounds were found to be active in psychotropic in vivo, anti-inflammatory in vivo and cytotoxicity in vitro screening. They possess marked sedative action, reveal high anti-inflammatory activity, have selective cytotoxic effects and NO-induction ability concerning tumour cell lines. Some of the compounds synthesized demonstrate antimicrobial action. An attempt was made to correlate the biological results with their structural characteristics and physicochemical parameters. Some specific combinations of types of activities for the synthesized compounds have been revealed.

Combination of bioactive moieties with different heteroatom(s): Application of the Suzuki cross-coupling reaction

Two series of thiophene/benzothiophene-linked quinolinyl oxadiazoles condensed to the substituted N-benzothiazolyl acetamides have been synthesized via the Suzuki cross-coupling reaction. The ester derivative of 6-bromo-substituted quinoline was reacted via the Suzuki cross-coupling reaction with commercially available (benzo)thiophen-2-ylboronic acid at optimized temperature in 1,2-dimethoxy ethane and water in the presence of potassium carbonate and palladium tetrakis. The resulting derivatives were then hydrazinolized using 99% hydrazine hydrate followed by cyclization using carbon disulfide in ethanolic KOH to furnish the corresponding oxadiazoles, which were then condensed with various substituted 2-chloro-N-benzothiazolyl acetamides to produce the final scaffolds involving a unique combination of four heterocycles to be examined for their antimicrobial activity against two Gram-positive bacteria (Staphylococcus aureus and Bacillus cereus), three Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa, and Klebsiella pneumoniae), and two fungal species (Aspergillus niger and Candida albicans). The investigation of biological screening data revealed that the majority of the compounds tested have demonstrated excellent activity (minimum inhibitory concentrations; 6.25-50 mug/mL) against most of the microorganisms as compared with the standard and hence they warrant more consideration as prospective antimicrobial agents. New products (9a-10i) were characterized by physicochemical, elemental, and spectral (IR, 1H NMR, and 13C NMR) data.

Copper-mediated fluorination of aryl iodides

The synthesis of aryl fluorides has been studied intensively because of the importance of aryl fluorides in pharmaceuticals, agrochemicals, and materials. The stability, reactivity, and biological properties of aryl fluorides can be distinct from those of the corresponding arenes. Methods for the synthesis of aryl fluorides, however, are limited. We report the conversion of a diverse set of aryl iodides to the corresponding aryl fluorides. This reaction occurs with a cationic copper reagent and silver fluoride. Preliminary results suggest this reaction is enabled by a facile reductive elimination from a cationic arylcopper(III) fluoride.
