Mild and practical method for the alpha-arylation of nitriles with heteroaryl halides

A mild and transition-metal-free method for thealpha-arylation of a liphatic nitriles with activated heteroaryl halides was developed using NaHMDS o r KHMDS as base at ambient temperature. The key to the success of this method is generation of the nitrile anion in the presence of the heteroaryl halide. The method is applicable to both primary and secondary carbonitriles and a wide range of heteroaryl halides. Selective monoarylation was observed with primary carbonitriles. The operational simplicity and the mild reaction conditions add to the value of this methodas a practical alternative to the preparation of alpha-heteroaryl carbonitriles.

Novel broad-spectrum and long-acting parenteral cephalosporins having an acyl cyanamide moiety at the C-3 terminal: Synthesis and structure-activity relationships

A series of novel 7beta-[2-(2-aminothiazole-4-yl)-2-(Z)-(alkoxyimino)acetamido]-cephalosporins having pyridinium-linked acyl cyanamide at the C-3 position were prepared and their antibacterial activities and pharmacokinetics profiles were evaluated. Most of the compounds exhibited potent antibacterial activities against penicillin-resistant Streptococcus pneumoniae (PRSP) and beta-lactamase non-producing penicillin-resistant Haemophilus influenzae (BLNAR). Introduction of a propenyl group between the cephalospoin core and the side chains at the C-3 position improved the pharmacokinetics profile. Among these compounds, 7beta-[2-(2-aminothiazole-4-yl)-2-(Z)- (alkoxyimino)acetamido]-3-(pyridin-1-ium-1-yl)prop-1-en-1-yl)cephalosporins (32j) showed well-balanced antibacterial activity against S.?pneumoniae and H.?influenzae which included resistant strains and also other Gram-positive or Gram-negative pathogens. Furthermore, 32j showed a long half-life comparable to that of Ceftriaxone in mice and monkeys.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of C10H7NO2, you can also check out more blogs about106778-43-2

An amide probe as a selective Al3+ and Fe3+ sensor inside the HeLa and a549 cell lines: Pictet-Spengler reaction for the rapid detection of tryptophan amino acid

In the present study, an amide-based chemosensor L is reported for the selective determination of tri-positive Al3+ and Fe3+ metal ions via the fluorescence (FL) “turn-on” state. L can be further used as an Al3+ ion sensor in live cells with a significant emission at 430 nm. The receptor showed high binding affinities of 1.045 ¡Á 105 and 6.234 ¡Á 105 M-1 for Al3+ and Fe3+, respectively. Furthermore, the chemosensor L also specifically senses tryptophan (Trp) upon the introduction of various amino acids. ESI-MS data and spectroscopic studies indicate a probable intermediate formation through the Pictet-Spengler reaction between amide L and Trp. Trp can be also recognized as a FL quencher in the presence of L + Al3+ in an aqueous solution. A PET-based mechanism is proposed for the FL enhancement upon complexation, which is further supported by DFT calculations. Tryptophan, which is the main counterpart of BSA, can be introduced as a real sample to verify the selective PL quenching response. The receptor provides an LOD response of 2.43 ¡Á 10-7 M for the Trp amino acid, suggesting the practical application of tryptophan detection in an aqueous medium for any biological sample.

Virtual Screening Approach and Investigation of Structure-Activity Relationships to Discover Novel Bacterial Topoisomerase Inhibitors Targeting Gram-Positive and Gram-Negative Pathogens

Bacterial resistance is increasing rapidly, requiring urgent identification of new antibacterial drugs that are effective against multidrug-resistant pathogens. Novel bacterial topoisomerase inhibitors (NBTIs) provide a new strategy for investigating the well-validated DNA gyrase and topoisomerase IV targets while preventing cross-resistance issues. On this basis, starting from a virtual screening campaign and subsequent structure-based hit optimization guided by X-ray studies, a novel class of piperazine-like NBTIs with outstanding enzymatic activity against Staphylococcus aureus and Escherichia coli DNA gyrase and topoisomerase IV was identified. Notably, compounds (¡À)-33, (¡À)-35, and (¡À)-36 with potent and balanced multitarget enzymatic profiles exhibited excellent efficacy against selected Gram-positive and Gram-negative pathogens, as well as clinically relevant resistant strains. Overall, the new NBTI chemotype described herein, owing to the broad-spectrum antibacterial activity and favorable in vitro safety profile, might serve as a basis for the development of novel treatments against serious infections.

Diastereoselective synthesis of epoxide-fused benzoquinolizidine derivatives using intramolecular domino aza-Michael addition/Darzens reaction

An efficient and diastereoselective strategy based on an intramolecular domino aza-Michael/Darzens reaction to synthesize epoxide-fused benzoquinolizidines has been described. Three bonds (1 C-C, 1 C-N and 1 C-O), three rings and three chiral centers can be constructed in a single pot under very mild conditions. All the products were isolated in only one diastereomer with 40-80% yields.

Structure-activity study of 2,3-benzodiazepin-4-ones noncompetitive AMPAR antagonists: Identification of the 1-(4-amino-3-methylphenyl)-3,5-dihydro-7,8-ethylenedioxy-4H-2,3-benzodiazepin-4-one as neuroprotective agent

In the search for AMPA receptor (AMPAR) antagonists, 2,3-benzodiazepines represent a family of specific noncompetitive antagonists with anticonvulsant and neuroprotective properties. We have previously shown that 2,3-benzodiazepin-4-ones possess marked anticonvulsant properties and high affinity for the noncompetitive binding site of the AMPAR complex. In this paper, we report the synthesis and pharmacological characterization of a full set of 2,3-benzodiazepin-4-ones in order to better define the structure-activity relationship (SAR) of this class of compounds. Binding assays and functional tests were performed to evaluate the antagonistic activity at the AMPARs. Through these results we have identified a potent AMPAR antagonist, 1-(4-amino-3-methylphenyl)-3,5-dihydro-7,8-ethylenedioxy-4H-2,3-benzodiazepin-4-one (5c). This compound noncompetitively inhibited AMPAR-mediated toxicity in primary mouse hippocampal cultures with an IC50 of 1.6 muM and blocked kainate-induced calcium influx in rat cerebellar granule cells with an IC50 of 6.4 muM. Thus, 5c has the in vitro potential as therapeutic drug in the treatment of various neurological disorders.

Applications of Palladium-Catalyzed C-N Cross-Coupling Reactions

Pd-catalyzed cross-coupling reactions that form C-N bonds have become useful methods to synthesize anilines and aniline derivatives, an important class of compounds throughout chemical research. A key factor in the widespread adoption of these methods has been the continued development of reliable and versatile catalysts that function under operationally simple, user-friendly conditions. This review provides an overview of Pd-catalyzed N-arylation reactions found in both basic and applied chemical research from 2008 to the present. Selected examples of C-N cross-coupling reactions between nine classes of nitrogen-based coupling partners and (pseudo)aryl halides are described for the synthesis of heterocycles, medicinally relevant compounds, natural products, organic materials, and catalysts.
