From ketones to esters by a Cu-catalyzed highly selective C(CO)-C(alkyl) bond cleavage: Aerobic oxidation and oxygenation with air

The Cu-catalyzed aerobic oxidative esterification of simple ketones via C-C bond cleavage has been developed. Varieties of common ketones, even inactive aryl long-chain alkyl ketones, are selectively converted into esters. The reaction tolerates a wide range of alcohols, including primary and secondary alcohols, chiral alcohols with retention of the configuration, electron-deficient phenols, as well as various natural alcohols. The usage of inexpensive copper catalyst, broad substrate scope, and neutral and open air conditions make this protocol very practical. 18O labeling experiments reveal that oxygenation occurs during this transformation. Preliminary mechanism studies indicate that two novel pathways are mainly involved in this process. (Chemical Equation Presented)

Quinazoline-based multi-tyrosine kinase inhibitors: Synthesis, modeling, antitumor and antiangiogenic properties

In this work the synthesis and the biological evaluation of some novel anilinoquinazoline derivatives carrying modifications in the quinazoline scaffold and in the aniline moiety were reported. Preliminary cytotoxicity studies identified three derivatives, carrying dioxygenated rings fused on the quinazoline portion and the biphenylamino substituent as aniline portion, as the most effective compounds. Further investigations revealed that these compounds exhibited antiproliferative activity on a wide panel of human tumor cell lines through the inhibition of both receptor and nonreceptor TKs. Furthermore, the compound bearing the dioxolane nucleus was also able to inhibit in vivo tumor growth. Molecular modeling of these compounds into kinase domain suggested that the phenyl group allows favorable interaction energies with the target proteins: this feature is favored by fused dioxygenated ring at the 6,7 positions, whereas free rotating functions do not allow the correct placement of the molecule, thus impairing the inhibitory potency. Finally, the biphenylamino derivatives, at noncytotoxic concentrations, acted as antiangiogenic agents both in in vitro and in vivo assays.

Synthesis and structure-activity relationships of novel phenoxyacetamide inhibitors of the Pseudomonas aeruginosa type III secretion system (T3SS)

The increasing prevalence of drug-resistant bacterial infections is driving the discovery and development not only of new antibiotics, but also of inhibitors of virulence factors that are crucial for in vivo pathogenicity. One such virulence factor is the type III secretion system (T3SS), which plays a critical role in the establishment and dissemination of Pseudomonas aeruginosa infections. We have recently described the discovery and characterization of a series of inhibitors of P. aeruginosa T3SS based on a phenoxyacetamide scaffold. To better characterize the factors involved in potent T3SS inhibition, we have conducted a systematic exploration of this structure, revealing several highly responsive structure-activity relationships indicative of interaction with a specific target. Most of the structural features contributing to potency were additive, and combination of those features produced optimized inhibitors with IC50 values <1 muM.

Labeling of benzodioxin piperazines with fluorine-18 as prospective radioligands for selective imaging of dopamine D4 receptors

The D4 receptor is of high interest for research and clinical application but puts high demands on appropriate radioligands to be useful tools for investigation. Search for adequate radioligands suitable for in vivo imaging is therefore still in progress. The potential neuroleptic drug 6-(4-[4-fluorobenzyl]piperazin-1-yl)benzodioxin shows high affinity and selectivity to the D4 receptor. Derivatization of this lead structure by adding hydrophilic moieties was carried out in order to lower its lipophilicity what led to three new putative dopamine receptor D4 ligands. A comprehensive description of the syntheses of standard compounds and corresponding labeling precursors is given which were obtained in satisfactory yields. Furthermore, the radiosyntheses by direct 18F-labeling and build-up synthesis were compared. All derivatives of 6-(4-[4-fluorobenzyl]- piperazin-1-yl)benzodioxin were successfully synthesized in 18F- labeled form with radiochemical yields of 9-35% and molar activities of 30-60 GBq/mumol using one-pot procedures. 2013 John Wiley & Sons, Ltd. Derivatives of the lead structure 6-(4-[4-fluorobenzyl]-piperazine-1-yl) benzodioxin were successfully synthesized, labeled via direct 18F-substitution or build-up synthesis leading to new putative radioligands for imaging of the dopamine D4 receptor. Reductive amination proved as the method of choice for preparation of substituted benzyl-derivatives of piperazine as precursors and standards, and also superior for build-up radiofluorination (RCY = 9 – 35;%) in comparison to direct 18F- labeling (RCY = 1 – 5;%).

Salicylanilide inhibitors of Toxoplasma gondii

Toxoplasma gondii (T. gondii) is an apicomplexan parasite that can cause eye disease, brain disease, and death, especially in congenitally infected and immune-compromised people. Novel medicines effective against both active and latent forms of the parasite are greatly needed. The current study focused on the discovery of such medicines by exploring a family of potential inhibitors whose antiapicomplexan activity has not been previously reported. Initial screening efforts revealed that niclosamide, a drug approved for anthelmintic use, possessed promising activity in vitro against T. gondii. This observation inspired the evaluation of the activity of a series of salicylanilides and derivatives. Several inhibitors with activities in the nanomolar range with no appreciable in vitro toxicity to human cells were identified. An initial structure-activity relationship was explored. Four compounds were selected for evaluation in an in vivo model of infection, and two derivatives with potentially enhanced pharmacological parameters demonstrated the best activity profiles.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 22013-33-8, help many people in the next few years.Safety of 2,3-Dihydrobenzo[b][1,4]dioxin-6-amine
