Amino acid derivatives are molecules of interest for medicinal chemistry and drug design studies due to their important chemical properties. In this study, the inhibition effects of some non-proteinogenic amino acid derivatives (hippuric acid (A), N-(9-Fluorenylmethoxycarbonyl)-D-valine (B), N-Z-(1-Benzotriazolylcarbonyl) methylamine (C), (S)-N-Z-1-Benzotriazolylcarbonyl-2-phenylethylamine (D)) on carbonic anhydrase I (hCA-I), II (hCA-II) isoenzymes and acetylcholinesterase (AChE) activity, whose inhibitors are of vital pharmacological importance, were examined. While carbonic anhydrase (CA) inhibitors are effective molecule candidates for the treatment of many diseases from glaucoma to cancer, acetylcholinesterase inhibitors are target molecules for the treatment of Alzheimer's disease. According to the results of this study, compound D had a strong inhibitory effect on hCA-I (IC50: 0.840 microM) and hCA-II (IC50: 0.661 microM), while compound B (IC50: 100 microM) showed a strong inhibitory effect on AChE activity. In addition, inhibition results were supported by molecular modeling studies. We hope that the obtained results will contribute to the synthesis of new and effective amino acid derivative inhibitors for CA and AChE.
