Synthesis, crystal structure and biological activity screening of novel N-(α-bromoacyl)-α-amino esters containing valyl moiety

Abstract

Three novel N-(α-bromoacyl)-α-amino esters: methyl 2-(2-bromo-3-methylbutanamido)pentanoate (1), methyl 2-(2-bromo-3-methylbutanamido)-2-phenylacetate (2) and methyl 2-(2-bromo-3-methylbutanamido)-3-phenylpropanoate (3) were synthesized. Single crystal X-ray diffraction data are reported for compounds 1 and 2. The cytotoxicity, antiinflammatory and antibacterial activity of compounds 1-3 were investigated. Additionally, the physico-chemical properties of studied compounds were calculated and an in silico toxicological study of compounds 1-3 was performed. The low level of cytotoxicity and absence of antibacterial and anti-inflammatory activity of 1-3 in tested concentrations might be a beneficial prerequisite for their incorporation in prodrugs.

Synthesis, Antimicrobial Activity and in silico Studies on Thymol Esters

“…Taking in consideration predicted in silico properties and estimated drug likeness score, pharmacological and toxicological profile, thymyl esters might be used as prodrugs. Among the chemical bonds used to link parental drug and carrier, esters have already proven to be promising due to their amenability to hydrolysis in vivo and are most frequently used in order to enhance the lipophilicity 52 and passive membrane transport.…”

Synthesis, Antimicrobial Activity and in silico Studies on Eugenol Eters

“…Taking in consideration predicted in silico properties and estimated drug likeness score, pharmacological and toxicological profile, eugenyl esters might be used as prodrugs of eugenol due to an expected enhanced lipophilicity 53 and passive membrane transport.…”
