Abstract:
Recently we described a group of purine derivatives based on theophylline structure with acetic acid moiety. Studies in a group of these compounds demonstrated their analgesic and anti-inflammatory properties. Taking into account wide spectrum of theophylline derivatives activity and searching for their new properties. the aim of the study was to evaluate safety of newly synthesized derivatives in human keratinocytes model. The effect of new purine derivatives with acetic acid moiety: 2-(8-methoxy-1,3-dimethyl-2,6-dioxo-purin-7-yl) acetic acid and 2-(1,3-dimethyl-2,6,8-trioxo-9H-purin-7-yl) acetic acid on proliferation rate and the ability of keratinocytes to migration was carried out. The results clearly demonstrate that purine derivatives with acetic acid moiety did not affect basic keratinocytes functions. Our compounds do not inhibit cells proliferation rate as well as their ability to migration. It can be therefore concluded that new purine derivatives with acetic acid moiety are safe versus normal cells. This observation opens up additional prospects in searching for their new applications.

Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the unhybridized p...

DNA and RNA
The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is in the nucleus of eukaryotes and in the organelles, chloroplasts, and mitochondria. In prokaryotes,...
Nomenclature of Carboxylic Acid Derivatives: Acid Halides, Esters, and Acid Anhydrides
The IUPAC and common names of acid halides are derived from the corresponding carboxylic acids, by changing “ic acid” to “yl halide.” For example, as shown below, the IUPAC name ethanoyl chloride is derived from ethanoic acid, and the common name, acetyl chloride, is obtained from acetic acid.
