Pyridazines were allowed to react with allyltributyltin in the presence of chloroformate to give 1-alkoxycarbonyl-6-allyl- and 1-alkoxycarbonyl-4-allyldihydro-pyridazines as major and minor products respectively.The reaction was applied to other diazines, and tetrahydro-adducts were obtained in the case of pyrimidine and pyrazine.Benzo-fused diazines also reacted in the same manner to afford the allyl-adducts in good yields.

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%.

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 141-30-0category: pyridazine

Chemical engineers work across a number of sectors, processes differ within each of these areas, but chemistry and chemical engineering roles are directly involved in the design, creation and manufacturing process of chemical products and materials. Application In Synthesis of 3-Phenyl-6-chloropyridazine

Herein, we describe in full our investigations into the synthesis of grassypeptolide A (1) in 17 linear steps with an overall yield of 11.3 %. In particular, this work features the late-stage introduction of sensitive bis(thiazoline) heterocycles and 31-membered macrocyclization conducted at the sterically congested secondary amide site in superb conversion (72 % yield). Biological evaluation indicated that grassypeptolide A significantly inhibited cancer cell proliferation in a dose-dependent manner. It induced cancer cell apoptosis, which was associated with increased cleavage of poly(ADP-ribose) polymerase (PARP) and decreased expression of bcl-2 and bcl-xL. Furthermore, grassypeptolide A also caused cell cycle redistribution by increasing cells in the G1 phase and decreasing cells in the S and G2 phases. In addition, cell cycle arrest was correlated with downregulation of cyclin D and upregulation of p27 and p21. Cytotoxic activity: Synthesis of grassypeptolide A, an anticancer marine cyclodepsipeptide, in 17 linear steps with an overall yield of 11.3 % is described (see figure). Subsequent biological evaluation indicated that grassypeptolide A significantly inhibited cancer-cell proliferation in a dose-dependent manner. Copyright
