Hepatocellular carcinoma is one of the most common kind of cancers in clinical, and its clinical treatment is quite difficult. The latest research suggests that pyridazinone with a novel molecular skeleton shows excellent activity against hepatocellular carcinoma in vitro and in vivo. Considering YHHU-759 as the leading compound for reasonable structure modification, a series of 3,3?-bipyridazine derivatives including 8 novel compounds in this study were designed, synthesized and screened for their anti-hepatoma activities against liver cancer cell lines SMMC-7721, BEL-7402 and QGY-7703 in vitro. The result shows that all of the 3,3?-bipyridazine derivatives have good anti-hepatoma activities.

Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.Read on for other articles about 141-30-0Application In Synthesis of 3,6-Dichloropyridazine

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Electric Literature of 141-30-0. Introducing a new discovery about 141-30-0, Name is 3,6-Dichloropyridazine

A wide range of alkyl-, aryl- and heteroarylzinc halides were aminated with highly functionalized alkyl, aryl, and heterocyclic azides. The reaction proceeds smoothly at 50 C within 1 h in the presence of FeCl3 (0.5 equiv) to furnish the corresponding secondary amines in good yields. This method was extended to peptidic azides and provided the arylated substrates with full retention of configuration. To demonstrate the utility of this reaction, we prepared two amine derivatives of pharmaceutical relevance using this iron-mediated electrophilic amination as the key step.

Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. A catalyst does not appear in the overall stoichiometry of the reaction it catalyzes. “Electric Literature of 141-30-0

category: pyridazine, The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic and theoretical assessments of solvent structures and their interactions with reaction intermediates and transition states.

A family of 12 triazolo-pyridazine-6-yl-substituted piperazines (5a-l) was synthesized and evaluated for their Dipeptidyl peptidase-4 (DPP-4) inhibition potentials in order to develop them as anti-diabetic medications. In the two-step synthesis process, 6-chloro-3-(m-tolyl)-[1,2,4]triazolo[4,3-b]pyridazine was synthesized with one-pot mode using pyridine, 3,6-dichloropyridazine 5-(3-methyl-phenyl)tetrazole in toluene. Conjugating corresponding 2 amines with 6-chloro-3-(m-tolyl)-[1,2,4]triazolo[4,3-b]pyridazine afforded the target triazolo-pyridazine-6-yl-substituted piperazines (5a-l). DPP-4 inhibition potential of these compounds was testified in silico and in nitro along with their insulinotropic activities in 832/13 INS-1 cells. H2O2 radical scavenging assay and MTT assay were conducted to assess the antioxidant and cytotoxicity of these compounds respectively. Molecular docking and ELISA based enzyme inhibition assay results revealed the strong inhibition potential of the target compounds. MTT assay results indicated a maximum dose of 2.5 nM (IC50 1.25 nM) could be used and above this level vital for the cells. Compounds 5a, 5c, 5g and 5i were found with excellent antioxidant and insulinotropic activity up to 99%.
