What's the difference between dimethyl and veratrol?

Dimethyl


Definition:

  • (n.) Ethane; -- sometimes so called because regarded as consisting of two methyl radicals. See Ethane.

Example Sentences:

  • (3) Glyceryl p-aminobenzoate and amyl p-dimethyl-aminobenzoate were labeled on 1 and 3 sunscreens, respectively, but glyceryl p-aminobenzoate was not found in any of them and only traces of amyl p-dimethylaminobenzoate were found in 1 sunscreen.
  • (4) Furthermore, it is insufficient to fully account for the transmembrane chemical shift differences observed for dimethyl methylphosphonate and hypophosphite.
  • (5) Radiation inactivation and simple target theory were employed to determine the molecular weight of an insect CNS alpha-bungarotoxin binding component in the presence and absence of a cross-linking reagent, dimethyl suberimate.
  • (6) The current study used the restraint model of stress ulceration to compare the effects of a more potent prostaglandin analogue, 16,16-dimethyl prostaglandin E2, with hyperosmolar glucose and antacids.
  • (7) However, when cells were grown in medium containing 2% dimethyl sulfoxide, as many as 50% of the cells had cilia with a 9+0 microtubular pattern.
  • (8) Finally, fosinopril had no effect on the pressor or chronotropic effects of norepinephrine (NE) or 1,1-dimethyl-4-phenylpiperinium (DMPP) or electrical stimulation of the sympathetic ganglia of pithed rats.
  • (9) BAY 19139, 1-(4-chlorophenoxy)-1-(1-imidazolyl)-3,3-dimethyl-2-butanol is a new imidazolyl derivative of antifungal agent.
  • (10) The continuous presence of 180 mM dimethyl sulfoxide (DMSO) during the culture specifically inhibited synthesis of type X collagen and accumulation of its mRNA.
  • (11) Dimethyl sulfoxide inhibits horse liver alcohol dehydrogenase.
  • (12) The NMR spectra of the two tRNA species in the region between 0 and 4 ppm below 4,4-dimethyl-4-silapentane-1-sulfonic acid (DSS) (methyl and methylene region) were the same except for the absence of the lowest field peak at 3.8 ppm in tRNAMet f3, thus unequivocally identifying this resonance at the methyl group of m7G47 of tRNAMet f1.
  • (13) Manoalide, manoalogue, and 7,7-dimethyl-5,8-eicosadienoic acid, effective inhibitors of the isolated PLA2, inhibited PGE2 production in intact P388D1 cells 40-85% in the concentration range studied.
  • (14) Equilibrium-partitioning measurements indicate that the relative affinities of different probes for PC-rich vesicles, in competition with HODMA or DOTAP vesicles, increase with increasing hydrogen-bonding capacity of the probe headgroup in the order PC less than N,N-dimethyl PE less than N-methyl PE less than PE approximately phosphatidyl-2-amino-1-propanol.
  • (15) The effect of vinpocetine was compared to other antioxidants, to mannitol, vitamin E and dimethyl sulfoxide.
  • (16) In order to identify the specific carboxyl groups labeled by ETC, a purified cytochrome c1 preparation containing both the heme peptide and the hinge peptide was dimethylated at all the lysines to prevent internal cross-linking.
  • (17) Since it is known that the enzyme has two binding sites per subunit for the substrate 6,7-dimethyl-8-ribityllumazine, it appears likely that each of the homologous protein domains provides one binding site.
  • (18) 6,8-O-Dimethyl-versicolorins A, B and 6-deoxyversicolorin A were found to be strongly mutagenic and genotoxic.
  • (19) We studied the effects of 16,16-dimethyl prostaglandin E2 (dm-PGE2) and sofalcone, a new antiulcer agent developed in Japan, on ethanol damage to isolated surface epithelial cells (SEC) in vitro and gastric mucosa of rats in vivo.
  • (20) Mice were exposed to hypoxia by enclosure in cages covered with dimethyl-silicone rubber membranes for 1-14 days.

Veratrol


Definition:

  • (n.) A liquid hydrocarbon obtained by the decomposition of veratric acid, and constituting the dimethyl ether of pyrocatechin.

Example Sentences:

  • (1) Veratrole (2-8 mM) was effective similarly to anisole on the A-current, but proved less potent.
  • (2) The effects of anisole (methoxybenzene) and veratrole (1,2-dimethoxybenzene) on the resting membrane potential (RMP), action potential (AP) and membrane potassium currents were investigated in snail neurons under current- and voltage-clamp conditions.
  • (3) 4,5-Dimethoxykynuramine was synthesized in a three-step sequence originating with veratrole.
