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 ...
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.
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 ...
It is a very stable group in most molecules. While the methyl group is usually part of a larger molecule, bonded to the rest of the molecule by a single covalent bond (−CH 3), it can be found on its own in any of three forms: methanide anion (CH − 3), methylium cation (CH + 3) or methyl radical (CH • 3).
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]
Methoxyacrylates hold significant importance in the field of agricultural fungicides, with a substantial market share. In 1999, this group of active ingredients accounted for over 10% of the fungicide market, with sales totaling US$620 million, led by azoxystrobin, which alone generated approximately US$415 million in sales.

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.
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).
