High impact information on N-methylmethanamine

• The hydrolysis of methyl 8-dimethylamino-1-naphthyl phosphate 4 and its reactions with a representative range of nucleophiles are catalyzed by the dimethylammonium group at acidic pH with rate accelerations of the order of 106 [1].
• For the voltage-independent action of highly permeant dimethylammonium, a more appropriate model might be a superficial binding site that did not prevent the flow of other ions, but depressed it [2].
• These [x,y]-ionenes are polyelectrolytic molecules consisting of dimethylammonium charge centers interconnected by alternating alkyl chain segments containing x and y methylene groups, some of which can form aggregate species whose properties mimic those of conventional surfactant micelles [3].
• The fluorescence of the p-nitrophenyl phosphonate and the inhibited enzyme varied with pH in a very similar fashion, reflecting dissociation of the dimethylammonium ion in the ground state at low pH and of the sulfonamide in the excited state above pH 6 [4].
• Similarly, incubation of ganglia with the specific antiacetylcholinesterase, BW 284 (1-5-bis[4-allyl dimethylammonium phenyl]pentan-3 one dibromide), increased the concentration of AF-DX 116 that was required to produce a comparable suppression of the s-IPSP [5].

Biological context of N-methylmethanamine

• Synergistic effects of U46 D fluid (dimethylammonium salt of 2,4-D) and CuCl2 on cytotoxicity and DNA repair in human fibroblasts [6].
• Synergistic effects of Cu(II) and dimethylammonium 2,4-dichlorophenoxyacetate (U46 D fluid) on PM2 DNA and mechanism of DNA damage [7].

Associations of N-methylmethanamine with other chemical compounds

• When two different anion-exchange resins having trimethylammonium and dimethylammonium groups as anion-exchange groups are employed for ion-exchange experiments, slightly higher Br- selectivity has been obtained with the former [8].
• The larger methylated and ethylated ammonium ions studied included: DMA (dimethylammonium), TMA (tetramethylammonium) and TEA (tetraethylammonium) and they all had permeability ratios larger than 0.09 [9].
• Spectroscopic evidence for pi-pi interaction between poly(diallyl dimethylammonium) chloride and multiwalled carbon nanotubes [10].

Gene context of N-methylmethanamine

• Thus, the mode of binding of PAV to HPS is defined by the cationic dimethylammonium headgroup fragment, whereas the negative fragment attenuates the effective charge of HPS headgroup [11].
• Study of local anaesthetics. Part 139. Preformulation study of N-[2-(2-heptyloxyphenylcarbamoyloxy)-ethyl] dimethylammonium chloride [12].
