An Eco-Friendly Stereoselective Synthesis of Novel Derivatives of Indeno[1,2-b]Pyrrole and Indeno[1,2-c]Pyridazine

A highly efficient and simple synthesis of a number of pharmaceutically interesting functionalized indenopirrole derivatives has been developed via the reaction of ninhydrin and acetoacetic acid amides in ethanol at the absence of catalyst at room temperature. In the case, then N,N-dialkylacetoacetamides were used as the methylene components, novel N,N-dialkyl-3-oxobutanamide derivatives were received. The novel indenopyridazine derivatives were first obtained via the reaction of indenopirroles with hydrazine.

Design and Synthesis of Novel 3-(2-Aminopyridin-3-yl)-1,2,4-Triazolo [4,3-b]Pyridazine Derivatives as a Reversible Bruton’s Tyrosine Kinase Inhibitors

Bruton’s tyrosine kinase, a non-receptor TEC family kinase, plays key role in B cell differentiation, proliferation, and survival. B cell receptor regulates the B cell’s fate and cytokine release of B-lineage lymphoid leukemia cells which are deeply related with the pathogenesis of B-cell lineage of lymphoma and leukemia and autoimmune diseases. Thus, BTK protein regulation emerged as a promising therapeutic target for both various cancers and autoimmune diseases.

Effective and Transition-Metal-Free Construction of Disubstituted, Trisubstituted 1,2,3-NH-Triazoles and Triazolo Pyridazine via Intermolecular 1,3-Dipolar Cycloaddition Reaction

An interesting approach for synthesis of disubstituted-1,2,3-(NH) triazoles from easily available raw materials and reagents like substituted acetophenones, iodine, DMSO and NaN3 via intermolecular 1,3-dipolar cycloaddition reaction. Trisubstituted triazoles and its corresponding triazolo pyridazine could be made easily using this method. These are key intermediates for poly benzodithiophene triazole (PBnDT-TAZ) for solar cells and 1-benzyl-1H-4,5-dibenzoyl-1,2,3-triazole (BDBT) for corrosion inhibition.

Acid-Induced Multicolor Fluorescence of Pyridazine Derivative

Smart luminescent materials that are responsive to external stimuli have received considerable attention. Here, we report a new D-A type 1,2-pyridiazine derivative (3,4,5,6tetrakis(4-methoxyphenyl)pyridazine (TPP)) exhibiting turn on fluorescence upon acid exposure both in solution and in the solid state. The protonation of the 1,2-pyridiazine ring caused a variation in the emission colors of the acidification species from blue (406 nm) to orange-red (630 nm) with a huge Ailem (224 nm). As a result, a synthetic rainbow of emission in solution could be achieved from one single molecule, and white photoluminescence was readily tuned by controlled protonation. A trifluoroacetic acid (TFA)-sensor film made from TPP was demonstrated as a TFA-sensitive surface with high sensitivity and reversibility. On the basis of these findings, we constructed a solid-state TPP film with a photoacid generator and demonstrated data encryption and decryption via a cascade protonation reaction that was well controlled by UV light.

Diffuse electron of alkali metals (Li, Na, K) or diffuse electron pair of alkaline earth metals (Be, Mg, Ca) which predict larger second hyperpolarizability? A comprehensive study of M center dot center dot center dot NH3 model compounds

In the present work, model M center dot center dot center dot NH3 complexes of alkali and alkaline earth metals are considered to calculate second hyperpolarizability using HF, MP2, CCSD and DFT methods. The diffuse electrons of alkali metals are more efficient than diffuse electron pair of alkaline earth metals in enhancing the magnitude of second hyperpolarizability. The radiation frequency has a dramatic effect on gamma(av). Although MP2 gamma(zzzz) is overestimated by a smaller margin the corresponding gamma(av) fairly agrees with the CCSD result. The large second hyperpolarizability of alkali metal (versus alkaline earth metal) complexes arises from the lower energy intense transition. (C) 2017 Elsevier B.V. All rights reserved.

Synthesis and Structure Activity Relationship of Pyridazine-Based Inhibitors for Elucidating the Mechanism of Amyloid Inhibition

Conformational diseases, constituting a large number of diseases, have been connected with protein misfolding, leading to aggregation known as amyloid fibrils. Mainly due to the lack of detailed molecular mechanisms, there has not been an effective drug to combat amyloid-associated diseases. Recently, a small organic pyridazine-based molecule (RS-0406) has shown significant reductions in amyloid fibrils in both in vitro and in vivo animal studies. However, no information on molecular details of inhibition for the small molecule has been reported. In this work, we have decided to explore structure activity relationship of pyridazine-based compounds to investigate structural parameters for amyloid inhibition. A number of closely related derivatives of RS-0406 were designed and synthesized to delineate the roles of structural properties, including bulkiness and halogen bonding, hydrogen-bonding ability, and the position of substituents on the flanking aromatic rings of the synthetic molecules. To examine the effectiveness of the synthesized compounds, amyloid fibril formation of hen egg white lysozyme was measured in the presence of each synthetic molecule. Our results indicated that in addition to the type of the aryl substituent, their positions on the ring were also important for their inhibitory roles in amyloid fibrils formation. Moreover, a fluorinated compound turned out to be a more effective kinetic inhibitor, displaying a delayed fibril nucleation than the original lead compound. Furthermore, biochemical structural analyses and molecular dynamics simulation revealed that the pyridazine-based compounds may mediate the inhibition of amyloid fibrils through stabilization of the protein monomer during partially unfolded state. The cytotoxicity assay revealed that the amounts of amyloid intermediates were reduced in the presence of the synthetic compounds. Eventually, IC50 values were obtained for the synthetic compounds, and quantitative structure activity relationship method was employed to suggest more effective amyloid inhibitors.

Development of an LC-MS method for determination of nitrogen-containing heterocycles using mixed-mode liquid chromatography

N-containing heterocycles (NCHs) are largely used as precursors for pharmaceuticals and can enter the environment. Some NCHs have been shown to be toxic, persistent, and very mobile in the environment. Thus, they have received increasing attention in the past years. However, the analysis of these polar compounds in environmental samples is still a challenge for liquid chromatography. This paper investigates the use of mixed-mode liquid chromatography (MMLC), which has reversed-phase and ion exchange characteristics for measurements of NCHs in water. NCHs with low pK(a) (i.e., < 2.5) display mainly reversed-phase interactions (neutral species) with the stationary phase and those with higher pK(a) (i.e., > 5) interact by a mixture of reversed-phase/ion exchange/HILIC mechanism. It was also shown that the presented method performs well in the quantification of the majority of the selected NCHs in surface water with MDLs between 3 and 6 mu g/L, a low matrix effect and recoveries in the range of 77-96% except for pyridazine exhibiting 32% were achieved. The method was successfully employed to follow the degradation of NCHs in ozonation.
