Synthesis and Evaluation of Novel 3-Allylseleno-6-Alkylsulfonylpyridazine Derivatives with Potential Anticancer Properties

A new series of 3-allylseleno-6-alkylsulfonylpyridazines and 3-allylseleno-6-alkylsulfinylpyridazines were synthesized from 3,6-dichloropyridazine for anticancer agent development. The inhibitory effects of 3-allylseleno-6-alkylsulfonylpyridazines on human cancer cell lines were investigated. The synthesis involved thiolation, oxidation, selenylation, and Se-allylation of alkylthiols. That is, sodium methanethiolate, ethanethiol, propanethiol, butanethiol, pentanethiol, and hexanethiol were inserted into the 6-position of the pyridazine nucleus. These new synthetic compounds exhibited antiproliferative activity against human breast cancer (MCF-7), hepatocarcinoma (Hep3B), and human colon carcinoma (RKO) cells in CCK-8 assays, and are potential candidates for cancer chemotherapy.

Challenges in the development of an M-4 PAM preclinical candidate: The discovery, SAR, and biological characterization of a series of azetidine-derived tertiary amides

Herein we describe the continued optimization of M-4 positive allosteric modulators (PAMs) within the 5-amino-thieno[2,3-c] pyridazine series of compounds. In this letter, we disclose our studies on tertiary amides derived from substituted azetidines. This series provided excellent CNS penetration, which had been challenging to consistently achieve in other amide series. Efforts to mitigate high clearance, aided by metabolic softspot analysis, were unsuccessful and precluded this series from further consideration as a preclinical candidate. In the course of this study, we found that potassium tetrafluoroborate salts could be engaged in a tosyl hydrazone reductive cross coupling reaction, a previously unreported transformation, which expands the synthetic utility of the methodology.

Synthesis and Biological Evaluation of Novel Neuroprotective Pyridazine Derivatives as Excitatory Amino Acid Transporter 2 (EAAT2) Activators

LDN-212320 (3) was found to be a potent EAAT2 activator at a translational level, restoring the normal clearance of glutamate and providing neuronal protection. Since the pharmacologic activation of EAAT2 represents a valuable strategy to relieve neuropathic pain, we synthesized novel activators (4a-f) of EAAT2. Among them 4f, analyzed in comparison with 3 by different paradigms in a rat model of oxaliplatin-induced neuropathic pain, showed the better antihypersensitive profile being able to fully counteract the oxaliplatin-induced neuropathy.

BF3 center dot SMe2 for Thiomethylation, Nitro Reduction and Tandem Reduction/SMe Insertion of Nitrogen Heterocycles

Herein, a general, solvent-free and straightforward thiomethylation of electron deficient heterocycles using BF3 center dot SMe2 as a dual thiomethyl source and Lewis acidic activator is presented. A range of heterocycles including pyrimidine, pyrazine, pyridazine, thiazole and purine derivatives were successfully substituted using this method. An unexpected reductive property of BF3 center dot SMe2 towards nitropyridines was also discovered including an intriguing tandem reduction/SMe insertion process in certain substrates. Notable features of the present work include its convenience and use of a non-malodorous reagent while the discovery of novel chemical transformations using BF3 center dot SMe2 provides fundamental new insights into the reactivity of this commonly employed reagent.

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 920-66-1 help many people in the next few years. SDS of cas: 920-66-1.

Delivering strong H-1 nuclear hyperpolarization levels and long magnetic lifetimes through signal amplification by reversible exchange

Hyperpolarization turns typically weak NMR and MRI responses into strong signals so that ordinarily impractical measurements become possible. The potential to revolutionize analytical NMR and clinical diagnosis through this approach reflect this area’s most compelling outcomes. Methods to optimize the low-cost parahydrogen-based approach signal amplification by reversible exchange with studies on a series of biologically relevant nicotin-amides and methyl nicotinates are detailed. These procedures involve specific H-2 labeling in both the agent and catalyst and achieve polarization lifetimes of ca. 2 min with 50% polarization in the case of methyl-4,6-d(2)-nicotinate. Because a 1.5-T hospital scanner has an effective H-1 polarization level of just 0.0005% this strategy should result in compressed detection times for chemically discerning measurements that probe disease. To demonstrate this technique’s generality, we exemplify further studies on a range of pyridazine, pyrimidine, pyrazine, and isonicotinamide analogs that feature as building blocks in biochemistry and many disease-treating drugs.

Identification of novel scaffolds to inhibit human mitotic kinesin Eg5 targeting the second allosteric binding site using in silico methods

Human mitotic kinesins are potential anticancer drug targets because of their essential role in mitotic cell division. The kinesin Eg5 (Kinesin-5, kif11) has gained much attention in this regard and has many inhibitors in different phases of clinical trials. All drug candidates considered for Eg5 so far binds to the binding site (Site 1) formed by the loop L5, helices alpha 2 and alpha 3 and are uncompetitive to ATP/ADP. Recently, it has been reported that Eg5 also has a second binding site (Site 2) formed by helices alpha 4 and alpha 6. In the current work, we have screened the compounds in the diversity set-III from National Cancer Institute (NCI) and Zinc database to identify potential inhibitors for Eg5 that specifically binds to the site 2. The compounds were ranked based on the glide extra precision docking scores and the top ranked compounds were found to have pyridazine scaffold. The top five compounds were further evaluated for other drug like properties. Stability of protein-ligand complexes were analyzed using molecular dynamic simulations. Our studies suggest that pyridazine analogs have good MDCK, permeability properties and high binding affinity to the human Eg5.

Transforming Polybutadiene with Tetrazine Click Chemistry into Antioxidant Foams That Fluoresce with Oxidation

The extent to which oxidative degradation of macromolecules can be delayed is generally limited by the low solubility of antioxidants in most polymers. This can be surmounted by synthesizing macromolecule? with covalently attached antioxidant functionalities, but these are frequently expensive. Here, we demonstrate a simple click modification of polybutadienes (PDB) with 3,6-dichloro-1,2,4,5-tetrazine (DCT) that, in addition to modifying and stiffening the polymer chains, releases nitrogen gas to foam the solidifying polymers and generates dihydropyridazine groups that transform them into macromolecular antioxidants. Tetrazines react by a cycloaddition/cycloreversion reaction (Carboni Lindsey reaction) with the C=C bonds to install 1,4-dihydropyridazine groups that increase the mass and rigidity of the butadiene macromolecules. The 1,4-dihydropyridazine group is an effective antioxidant that donates two hydrogen atoms per ring to combine with radicals and forms an aromatic pyridazine ring whose white fluorescence under UV permits visual monitoring of oxidation. Foams made by reacting liquid hydroxyl-terminated polybutadienes with DCT stabilize with thermoset formation through substitution reactions between the hydroxyl and dichlorodihydropyridazine groups.

Preparation of an oxetan-phenyltetrahydropyridazine-3,6-dione derivative using some chemistry tools

The aim of this study was to synthesize a new oxetan-phenyltetrahydropyridazine-3,6-dione derivative (compound 6) using different techniques. The first method was achieved by the preparation of a phenylhydrazine derivative (2) using three-components system (3,17-aldol-estradiol, phenylhydrazine, 5-hexyn-3-ol) in the presence of Copper(II). Then, 2 was reacted with tert-butyldimethylsilyl chloride to form the compound 3 (trimethylbutan-silyloxy-steroid-hydrazine). Following, a pyridazine derivative (4) was prepared by the reaction of 3 with succinic acid using boric as catalyst. The compound 4 was reacted with hydrofluoric acid to form the tetrahydropyridazine-3,6-dione (5). Finally, the preparation of 6 was carried out by the reaction of 5 with CopperII. Spectroscopy analyses NMR was used to confirm the chemical structure of compounds. In conclusion, a facile method to synthesize an oxetan-phenyltetrahydropyridazine-3,6-dione is reported.

Experimental and theoretical investigation of the inhibitory effect of new pyridazine derivatives for the corrosion of mild steel in 1 M HCl

The effects of four pyridazine derivatives namely, 2-(6-chloropyridazin-3-yl)-2-phenylacetonitrile (P1), 3-(6-chloro-3-pyridazinyl)-1H-indole (P2), 4-(6-chloropyridazin-3-yl)benzoic acid (P3) and 3-(6chloropyridazin-3-yl)benzoic acid (P4) on electrochemical dissolution of mild steel in 1 M HCl were studied using electrochemical, spectroscopic, and theoretical computational chemistry techniques. The inhibition efficiency increases with increasing concentration of the inhibitors and the shift in corrosion potentials obtained revealed that the compounds are mixed-type inhibitors and steel dissolution was found to be a charge transfer process with the steel/electrolyte interface showed pseudo-capacitive behaviour. P1 and P2 showed the best protection performances for mild steel in the studied medium, attributable to the presence of more nitrogen atoms and unsaturated groups in their molecules compared to P3 and P4. The experimental adsorption data obeyed the Langmuir and Temkin isotherm models and was found to involve both physisorption and chemisorption. Spectroscopic studies revealed that the inhibitor molecules interact chemically with mild steel and the pyridazine ring is actively involved in these interactions. Quantum chemical calculations also showed that pyridazine ring has the tendency of interacting with metallic atoms via both forward and backward donations. Molecular dynamic simulation revealed that the molecules can adsorb strongly onto the surface of iron in a near flat orientation. (C) 2017 Elsevier B.V. All rights reserved.
