  2. Methoxy group - Wikipedia

    en.wikipedia.org/wiki/Methoxy_group

    The structure of a typical methoxy group. In organic chemistry, a methoxy group is the functional group consisting of a methyl group bound to oxygen. This alkoxy group has the formula R−O−CH 3. On a benzene ring, the Hammett equation classifies a methoxy substituent at the para position as an electron-donating group, but as an electron ...

  3. Melatonin receptor agonist - Wikipedia

    en.wikipedia.org/wiki/Melatonin_receptor_agonist

    The general structure of melatonin is the indole ring with methoxy group in position 5 (5-methoxy group) and acylaminoethyl side-chain in position 3. [1] The two side-chains are important for binding to and activating the receptors. [3] The indole ring has been evaluated at all positions by the effect of substitutions as seen in Figure 1. [1]

  4. 2'-O-methylation - Wikipedia

    en.wikipedia.org/wiki/2'-O-methylation

    The resulting protein would normally be solely dependent on the gene it was translated from, but the methylation of the RNA would influence the outcome of the protein as well. [1] This modification to the rRNA is done via ribonucleoprotein (snoRNP) [ 2 ] where a methyl group is added to the 2' hydroxyl of the ribose moiety of any nucleotide (Nm ...

  5. Alkoxy group - Wikipedia

    en.wikipedia.org/wiki/Alkoxy_group

    In chemistry, the alkoxy group is an alkyl group which is singularly bonded to oxygen; thus R−O. Denoted usually with apostrophe('). The range of alkoxy groups is vast, the simplest being methoxy (CH 3 O−). [1] An ethoxy group (CH 3 CH 2 O−) is found in the organic compound ethyl phenyl ether (C 6 H 5 OCH 2 CH 3, also known as ethoxybenzene).

  6. Discovery and development of proton pump inhibitors - Wikipedia

    en.wikipedia.org/wiki/Discovery_and_development...

    Omeprazole was the first PPI on the market, in 1988. It is a 1:1 racemate drug with a backbone structure of timoprazole, but substituted with two methoxy and two methyl groups. One of the methoxy group is at position 6 of the bensoimidazole and the other at position 4 of the pyridine and the methyl groups are at position 3 and 5 of the pyridine.

  7. Methoxyacetic acid - Wikipedia

    en.wikipedia.org/wiki/Methoxyacetic_acid

    Methoxyacetic acid is a colorless, viscous, and corrosive liquid with a pungent odor which, at 7 °C, freezes to a mass similar to glacial acetic acid. Due to the low solvation energy of its methoxy group, methoxyacetic acid, with a pKa value of 3.57, is more acidic than acetic acid (pKa 4.757) and glycolic acid (pKa 3.832). [3]

  8. Methyl group - Wikipedia

    en.wikipedia.org/wiki/Methyl_group

    In organic chemistry, a methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms, having chemical formula CH 3 (whereas normal methane has the formula CH 4). In formulas, the group is often abbreviated as Me. This hydrocarbon group occurs in many organic compounds. It is a very stable group in ...

  9. Protecting group - Wikipedia

    en.wikipedia.org/wiki/Protecting_group

    Orthogonal protection is a strategy allowing the specific deprotection of one protective group in a multiply-protected structure. For example, the amino acid tyrosine could be protected as a benzyl ester on the carboxyl group, a fluorenylmethylenoxy carbamate on the amine group, and a tert -butyl ether on the phenol group.
