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.

Pyridazine-bridged cationic diiridium complexes as potential dual-mode bioimaging probes

A novel diiridium complex [(N^C^N)2Ir(bis-N^C)Ir(N^C^N)2Cl]PF6 (N^C^N = 2-[3-tert-butyl-5-(pyridin-2-yl)phenyl]pyridine; bis-N^C = 3,6-bis(4-tert-butylphenyl)pyridazine) was designed, synthesised and characterised. The key feature of the complex is the bridging pyridazine ligand which brings two cyclometallated Ir(iii) metal centres close together so that Cl also acts as a bridging ligand leading to a cationic complex. The ionic nature of the complex offers a possibility of improving solubility in water. The complex displays broad emission in the red region (lambdaem = 520-720 nm, tau = 1.89 mus, Phiem = 62% in degassed acetonitrile). Cellular assays by multiphoton (lambdaex = 800 nm) and confocal (lambdaex = 405 nm) microscopy demonstrate that the complex enters cells and localises to the mitochondria, demonstrating cell permeability. Further, an appreciable yield of singlet oxygen generation (PhiDelta = 0.45, direct method, by 1O2 NIR emission in air equilibrated acetonitrile) suggests a possible future use in photodynamic therapy. However, the complex has relatively high dark toxicity (LD50 = 4.46 muM), which will likely hinder its clinical application. Despite this toxicity, the broad emission spectrum of the complex and high emission yield observed suggest a possible future use of this class of compound in emission bioimaging. The presence of two heavy atoms also increases the scattering of electrons, supporting potential future applications as a dual fluorescence and electron microscopy probe.

Synthesis of alkyl or aryl pyridazinyl ethers

This paper presents the synthesis of some alkyl or aryl pyridazinyl ethers from 2-alkyl-4-halo-5-hydroxy-and 2-alkyl-4,5-dichloropyridazin-3(2H)-ones or 3,6-dichloropyridazine. Reaction of 2-alkyl-4-halo-5-hydroxypyridazin-3(2H)-ones 1 with 1,2-dibromoethane or 1,3-dibromopropane gave the corresponding monopyridazin-5-yl ethers 2 and alpha,omega-[di(pyridazin-5-oxy)]alkanes 3. Treatment of 4 with 4-substituted-phenol afforded 5-(4-substituted-phenoxy)-2- (4-substituted-phenoxymethyl) derivatives 5. Reaction of 2-alkyl-4,5-dichloro derivatives 7 with 1 gave the corresponding di(pyridazin-5-yl) ethers 8 in good yields. Compound 10 was reacted with catechol to give monopyridazin-3-yl ether 11 and/or di(pyridazin-3-yl) ether 12. Also we described the results for the reaction of 2-alkyl-4-chloro-5-(4-substituted-phenoxy)pyridazin-3(2H)-ones with nucleophiles.

Synthesis, characterization, and antidiabetic activity of 6-methoxyimidazo[1,2-b]pyridazine derivatives

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.

Heteroatom-substituted analogues of orphan nuclear receptor small heterodimer partner ligand and apoptosis inducer (E)-4-[3-(1-adamantyl)-4- hydroxyphenyl]-3-chlorocinnamic acid

(E)-4-[3′-(1-Adamantyl)-4′-hydroxyphenyl]-3-chlorocinnamic acid (3-Cl-AHPC) induces the cell cycle arrest and apoptosis of cancer cells. Because its pharmacologic properties-solubility, bioavailability, and toxicity-required improvement for translation, structural modifications were made by introducing nitrogen atoms into the cinnamyl ring and replacing its E-double bond with XCH2 (X = O, N, and S) with the objective of enhancing these properties without impacting apoptosis-inducing activity. Analogues having nitrogen atoms in heterocyclic rings corresponding to the cinnamyl phenyl ring displayed equal or higher biological activities. The pyrimidine and pyridine analogues were more soluble in both phosphate-buffered saline and water. While the 2,5-disubstituted pyridine analogue was the most potent inducer of KG-1 acute myeloid leukemia cell apoptosis, on the basis of apoptotic activity in KG-1 cells and solubility, the 2,5-disubstituted pyrimidine proved to be the more promising candidate for treatment of acute myeloid leukemia.
