34231-77-1, Name is Methyl pyridazine-4-carboxylate, belongs to pyridazine compound, is a common compound. Quality Control of Methyl pyridazine-4-carboxylateIn an article, once mentioned the new application about 34231-77-1.

Various novel thiosemicarbazones (TSCs) 15b-e, 16b-e, 17b-e, 18b-e, and 19b-e derived from 4-pyridazinecarbaldehyde, 3-pyridazinecarbaldehyde, 4-acetylpyridazine, 3-acetylpyridazine, and 3-propionylpyridazine were prepared and their cytotoxic and antiherpetic potentials were evaluated. It was found that the replacement of the 2-pyridyl-moiety in aldehyde derived compounds 20a-c by a 4-pyridazinyl group (compounds 15b-d) abolishes biological activity. However, in TSCs derived from 3-pyridazinecarbaldehyde (16b-d) the cytotoxic potency was considerably reduced (factor ~300), while the antiviral activity was largely retained. A total loss of biological activity occurred when the pyridyl group in TSC 20d, derived from 2-acetylpyridine, was replaced by the 4-pyridazinyl system (17d). By employment of the 3-pyridazinyl unit for isosteric modification, however, the cell toxicity could be reduced significantly (factor 100) without impairing the antiherpetic potential also in the series of TSCs derived from N-heteroaromatic ketones. It was observed that there is no obvious influence of the size of the cycloamino substituent on the biological activities in compounds 20a-d, 15b-d, 16b-d, 17b-d, and 18b-d. While the pyridine derived TSCs in our experiments proved clearly cytotoxic at lower concentrations than those being antivirally active, the aza-analogous compounds derived from 3-acetyl-pyridazine (18b-e) inhibited plaque formation at concentrations equal to those causing cytotoxic effects. The TSCs 16b-e derived from 3-pyridazinecarbaldehyde were found to show selective antiviral activity against HSV-1. In addition, a significant improvement of the water solubility of heteroaromatic TSCs could be achieved by the replacement of the CH-moiety in position 6 of the pyridine derivatives 20a-c by a nitrogen atom (compounds 16b-d).

Rate constants for the reaction of six possible diazine monocarboxylates with diazodiphenylmethane (DDM) in ethanol, and also for the hydrolysis of the corresponding methyl carboxylate esters, have been determined at four selected temperatures.Correlations with sums of the Hammett ? constants for ring nitrogens treated as substituents, which are fairly satisfactory for the reaction with DDM at 30 deg C (rhoDDM = 0.64, log k0 = -1.54, r = 0.92, s = 0.12) and for ester hydrolysis (rhoEH = 2.28, log k0 = -3.36, r = 0.94, s = 0.36) are, however, excellent for the intercorrelation of the two reaction series (rhoDDM/rhoEH = 0.34, r = 0.99, s = 0.12).The reactivity of ortho- and para-diazine dicarboxylates in the reaction with DDM, in ethanol and dimethylformamide, has been investigated and compared with the corresponding reactions of ortho- and para-benzene- and pyridine-dicarboxylates.

New dinuclear hydrido-carbonyl rhenium complexes designed as photosensitizers in dye-sensitized solar cells

The possible use of some dinuclear rhenium complexes as sensitizers for dye sensitized solar cells (DSSCs) has been investigated. They have general formula [Re2(mu-X)(mu-Y)(CO)6(mu-pyridazine-4-COOH)], with X = Y = Cl (1), X = H, Y = benzoato (2), and X = H, Y = 4-diphenylaminobenzoato (3). An original synthetic strategy has been set for preparing the hydrido-carboxylato derivatives 2 and 3. They have been indicated by DFT and TD-DFT computations as the most promising dyes, endowed with good light harvesting capability. The complexes have absorption maxima in the range of 405-443 nm, on TiO2 films, arising from metal-to-ligand-charge transfer transitions. Cyclic voltammetry experiments have been performed on the derivatives containing the methyl ester of the pyridazine-4-COOH acid, showing electrochemical band gaps in the range of 2.25-1.63 eV. The best DSSC results have been obtained using complex 3, with an overall solar-to-electric conversion efficiency of 1.0%. Noteworthy the presence of a hydrido ligand did not show any detrimental effect on the stability of the sensitizers under the operating conditions.

An anthrone-based Kv7.2/7.3 channel blocker with improved properties for the investigation of psychiatric and neurodegenerative disorders

A set of novel Kv7.2/7.3 (KCNQ2/3) channel blockers was synthesized to address several liabilities of the known compounds XE991 (metabolic instability and CYP inhibition) and the clinical compound DMP 543 (acid instability, insolubility, and lipophilicity). Using the anthrone scaffold of the prior channel blockers, alternative heteroarylmethyl substituents were installed via enolate alkylation reactions. Incorporation of a pyridazine and a fluorinated pyridine gave an analog (compound 18, JDP-107) with a promising combination of potency (IC50 = 0.16 muM in a Kv7.2 thallium flux assay), efficacy in a Kv7.2/7.3 patch clamp assay, and drug-like properties.

Aroylhydrazone iron chelators: Tuning antioxidant and antiproliferative properties by hydrazide modifications

Aroylhydrazones such as salicylaldehyde isonicotinoyl hydrazone (SIH) are tridentate iron chelators that may possess antioxidant and/or antineoplastic activities. Their main drawback, their low stability in plasma, has recently been partially overcome by exchanging the aldimine hydrogen for an unbranched alkyl group. In this study, ten analogs of methyl- and ethyl-substituted SIH derivatives with modified hydrazide scaffolds were synthesized to further explore their structure-activity relationships. Their iron-chelation efficiencies, anti- or pro-oxidant potentials, abilities to induce protection against model oxidative injury on the H9c2 cell line derived from rat embryonic cardiac tissue, cytotoxicities on the same H9c2 cells and antiproliferative activities on MCF-7 human breast adenocarcinoma and HL-60 human promyelotic leukemia cell lines were evaluated. Compounds derived from lipophilic naphthyl and biphenyl hydrazides displayed highly selective antiproliferative activities against both MCF-7 and HL-60 cell lines, and they showed markedly improved stabilities in plasma compared to SIH. Of particular interest is a hydrazone prepared from 2-hydroxypropiophenone and pyridazin-4-carbohydrazide that showed a considerable antiproliferative effect and protected cardiomyoblasts against oxidative stress with a five-fold higher selectivity compared to the parent compound SIH. Thus, this work highlighted new structure-activity relationships among antiproliferative and antioxidant aroylhydrazones and identified new lead compounds for further development.
