Duplex molecular strands based on the 3,6-diaminopyridazine hydrogen bonding motif: Amplifying small-molecule self-assembly preferences through preorganization and iterative arrangement of binding residues

Structural parameters obtained through single-crystal X-ray diffraction analysis of the one-dimensional H-bonding motif expressed by 3,6-diaminopyridazine are applied to the design of related monomeric, dimeric, and trimeric duplex molecular strands. The mode of assembly and the interstrand affinity of the oligomers are established in solution by 1H NMR dilution experiments, isothermal titration calorimetry (ITC), and vapor pressure osmometry. Single-crystal X-ray crystallographic analysis of the dimeric diaminopyridazine 2a corroborates the intended duplex mode of assembly. Binding free energy per unimer (-DeltaG/n) increases upon extension from monomer to dimer to trimer, signifying a positive cooperative effect. Micromolar binding affinity (Kd = 1.25 ¡À 0.1 muM) was determined for the duplex trimer by ITC in 1,2-dichloroethane at 20C. These data provide further insight into the structural and interactional features of synthetic duplex oligomers required for high-affinity, high-specificity binding and define new recognition elements for use in nanoscale assembly.

Piperazinyl oxazolidinone antibacterial agents containing a pyridine, diazene, or triazene heteroaromatic ring

Oxazolidinones are a novel class of synthetic antibacterial agents active against gram-positive organisms including methicillin-resistant Staphylococcus aureus as well as selected anaerobic organisms. Important representatives of this class include the morpholine derivative linezolid 2, which is currently in phase III clinical trials, and the piperazine derivative eperezolid 3. As part of an investigation of the structure- activity relationships of structurally related oxazolidinones, we have prepared and evaluated the antibacterial properties of a series of piperazinyl oxazolidinones in which the distal nitrogen of the piperazinyl ring is substituted with a six-membered heteroaromatic ring. Compounds having MIC values ? 2 mug/mL vs selected gram-positive pathogens were discovered among each of the pyridine, pyridazine, and pyrimidine structural classes. Among these the cyanopyridine 17, the pyridazines 25 and 26, and the pyrimidine 31 exhibited in vivo potency vs S. aureus comparable to that of linezolid.

Multiple Multicomponent Reactions: Unexplored Substrates, Selective Processes, and Versatile Chemotypes in Biomedicine

Multiple multicomponent reactions rapidly assemble complex structures. Despite being very productive, the lack of selectivity and the reduced number of viable transformations restrict their general application in synthesis. Hereby, we describe a rationale for a selective version of these processes based in the preferential generation of intermediates which are less reactive than the initial substrates. In this way, applying the Groebke?Blackburn?Bienayme reaction on a range of alpha-polyamino-polyazines, we prepared a family compact heterocyclic scaffolds with relevant applications in medicinal and biological chemistry (live cell imaging probes, selective binders for DNA quadruplexes, and antiviral agents against human adenoviruses). The approach has general character and yields complex molecular targets in a selective, tunable and direct manner.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 61070-99-3 is helpful to your research. Reference of 61070-99-3

The present article describes the synthesis, characterization, and antidiabetic activity of 6-methoxyimidazo[1,2-b]pyridazine derivatives 7a-l. The synthetic sequence for the preparation of these derivatives involves the following prominent reactions: (a) Step 1: involves the high-pressure amination reaction; (b) Step 2: involves the Zinc oxide nanoparticle-catalyzed cyclization reaction; (c) Step 3: involves the methoxylation; (d) Step 4: involves the bromination reaction; (e) Step 5: involves the Suzuki coupling reaction; (f) Step 6: involves the reduction of the ?NO2 group; (g) Step 7: involves Boc protection of the 1o amino group (h) Step 8: involves diazotization of the amine group and finally the last of the synthesis (i) Step 9: involves the saponification of the ethyl ester group. Furthermore, the structures of the newly synthesized 6-methoxyimidazo[1,2-b]pyridazine derivatives 7a?l were determined using 1H NMR, 13C NMR, and Mass and IR spectroscopic analyses. These derivatives were evaluated for their antidiabetic property and the results revealed that most of the compounds exhibited significant potency. It is worth mentioning that compounds 7b (69.87%), 7f (69.0%), 7h (68.79%), and 7l (68.61%) with substitution R = para-NH2, para-COOH, meta-NH2, and meta-COOH, respectively, showed significant (good) hypoglycemic activity when compared to the standard drug insulin (50 mg/kg b.w) in reducing the blood glucose level.
