Basis on molecular docking and pharmacophore analysis of naphthoquinone moiety, a total of 23 compounds were designed and synthesised. With the help of reverse targets searching, anti-cancer activity was preliminarily evaluated, most of them are effective against some tumour cells, especially compound 12: 1-(5,8-dihydroxy-1,4-dioxo-1,4-dihydronaphthalen-2-yl)-4-methylpent-3-en-1-yl-4-oxo-4-((4-phenoxyphenyl)amino) butanoate whose IC50 against SGC-7901 was 4.1 ± 2.6 muM. Meanwhile the anticancer mechanism of compound 12 had been investigated by AnnexinV/PI staining, immunofluorescence, Western blot assay and molecular docking. The results indicated that this compound might induce cell apoptosis and cell autophagy through regulating the PI3K signal pathway.

The magnetic and decay properties of the short-lived triplet ( T1) states of pyridazine and 3, 6-dichloropyridazine ( DCP ) were studied by means of time-resolved EPR with laser excitation.The zfs of DCP in the p-dibromobenzene ( DBB ) host are X = 0.094 cm-1, – Y = – 0.164 cm-1, and Z = 0.070 cm-1, and the nitrogen hfcc are Ax = 27 G, Ay =18 G, and Az = 25 G, which confirms the n?* character of the T1 state.Similar zfs were obtained for DCP and pyridazine in other environments.The sublevel decay rate constants and the relative populating rates were determined from the analysis of the transient EPR signals measured at 3.0 K where the effect of the spin lattice relaxation can be neglected.It was found in both systems that ky is much greater than kx , kz as predicted by a simple group theoretical consideration. ky of DCP and pyridazine were determined to be on the order of 106 s-1, being larger than that of pyrimidine by a factor of ca. 104.The reasons for the large ky are discussed, particularly, in terms of the distorted potential of the T1 state.

Electric Literature of 141-30-0, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 141-30-0, Name is 3,6-Dichloropyridazine, molecular formula is C4H2Cl2N2. In a Article，once mentioned of 141-30-0

Reaction of 2-benzyl-5-halopyridazin-3(2H)-ones (3) with Grignard reagents followed by quenching with electrophiles unexpectedly yielded 4,5-disubstituted pyridazin-3(2H)-ones instead of 5-substituted pyridazin-3(2H)-ones. These reactions represent the first examples of cine substitution in which the anionic sigmaH-adduct is quenched by electrophiles (other than a proton) before elimination takes place. Insight into the reaction mechanism led to the direct transformation of 2-benzylpyridazin-3(2H)-one (7) and 2-benzyl-6-chloropyridazin-3(2H)-one (9) into the corresponding C-4 alkyl and aryl derivatives (when Br2 was used as the electrophile).

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, name: 6-Chloropyridazine-3-carbonitrile, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 35857-89-7, Name is 6-Chloropyridazine-3-carbonitrile, molecular formula is C5H2ClN3

The first catalytic enantioselective aminolysis of trans-2,3-epoxy alcohols has been accomplished. This stereo-specific ring-opening process was efficiently promoted by a tungsten/bis(hydroxamic acid) catalytic system, furnishing various anti-3-amino-1,2-diols with excellent regiocontrol and high enantioselectivities (up to 95% ee). Moreover, virtually enantiopure 3-amino-1,2-diols could be obtained by the sequential combination of two reactions that both involve the use of a chiral catalyst.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. name: 6-Chloropyridazine-3-carbonitrile, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 35857-89-7, in my other articles.
