Abstract
Achillea schischkinii Sosn. is an endemic plant species and it belongs to Asteraceae family. It is distributed widely in the Central and East Anatolia. This study was carried out for evaluation of the antioxidant activity, enzyme inhibition effect, elemental and phenolic content of A. schischkinii. Briefly, acetylcholinesterase (AChE), butyrylcholinesterase (BChE), α-glycosidase (α-Gly), and glutathione S-transferase (GST) enzymes were strongly inhibited by A. schischkinii. IC50 values for AChE, BChE, α-Gly, and GST enzymes were found as 19.3 mg/mL, 15.4 mg/mL, 69.3 mg/mL, and 34.7 mg/mL respectively. The antioxidant activity of the sample was evaluated by four different in vitro bioanalytical methods. Besides, the concentrations of twelve elements in A. schischkinii were analyzed by ICP-MS technique. Zn (50.6 ppm), Mn (23.0 ppm), and Cu (12.7 ppm) were found as major elements. Furthermore, catechin (20.8 µg/mg extract), trans-ferulic acid (18.3 µg/mg extract), and gallic acid (11.2 µg/mg extract) were characterized as major phenolic compounds by using HPLC. PRACTICAL APPLICATIONS: Acetylcholinesterase, butyrylcholinesterase, α-glycosidase, and glutathione s-transferase enzymes have crucial functions on metabolism. Enzyme inhibition or activation mostly attributed to some health disorders such as Alzheimer's disease, Diabetes mellitus, cancer and hyperglycemia. Phenolic contents are responsible for effective biological activity. This study evaluated the phenolic content and antioxidant activity of Achillea schischkinii as well as the inhibition effect against four metabolic enzymes. The results would be beneficial for using the plant in the food industry and pharmacological process.

Abstract
Recently, inhibition effects of enzymes such as acetylcholinesterase (AChE) and carbonic anhydrase (CA) has appeared as a promising approach for pharmacological intervention in a variety of disorders such as epilepsy, Alzheimer's disease and obesity. For this purpose, novel N-substituted rhodanine derivatives (RhAs) were synthesized by a green synthetic approach over one-pot reaction. Following synthesis the novel compounds, RhAs derivatives were tested against AChE and cytosolic carbonic anhydrase I, and II (hCAs I, and II) isoforms. As a result of this study, inhibition constant (Ki) were found in the range of 66.35 ± 8.35 to 141.92 ± 12.63 nM for AChE, 43.55 ± 14.20 to 89.44 ± 24.77 nM for hCA I, and 16.97 ± 1.42 to 64.57 ± 13.27 nM for hCA II, respectively. Binding energies were calculated with docking studies as -5.969, -5.981, and -9.121 kcal/mol for hCA I, hCA II, and AChE, respectively.

Abstract
Enantioselective synthesis of functionalized cyclic allylic alcohols via kinetic resolution in transesterifcation with different lipase enzymes has been developed. The influence of the enzymes and temperature activity was studied. By determination of ideal reaction conditions, byproduct formation is minimized; this made it possible to prepare enantiomerically enriched allylic alcohols in high ee's and good yields. Enantiomerically enriched allylic alcohols were used for enantiomerically enriched oxazolidinone synthesis. Using benzoate as a leaving group means that 1 mol % of potassium osmate is necessary and can be obtained high yields 98%. Inhibitory activities of enantiomerically enriched oxazolidinones (8, 10 and 12) were tested against human carbonic anhydrase I and II isoenzymes (hCA I and hCA II), acetylcholinesterase (AChE), and α-glycosidase (α-Gly) enzymes. These enantiomerically enriched oxazolidinones derivatives had Ki values in the range of 11.6 ± 2.1-66.4 ± 22.7 nM for hCA I, 34.1 ± 6.7-45.2 ± 12.9 nM for hCA II, 16.5 ± 2.9 to 35.6 ± 13.9 for AChE, and 22.3 ± 6.0-70.9 ± 9.9 nM for α-glycosidase enzyme. Moreover, they had high binding affinity with -5.767, -6.568, -9.014, and -8.563 kcal/mol for hCA I, hCA II, AChE and α-glycosidase enzyme, respectively. These results strongly supported the promising nature of the enantiomerically enriched oxazolidinones as selective hCA, AChE, and α-glycosidase inhibitors. Overall, due to these derivatives' inhibitory potential on the tested enzymes, they are promising drug candidates for the treatment of diseases like glaucoma, leukemia, epilepsy; Alzheimer's disease; type-2 diabetes mellitus that are associated with high enzymatic activity of CA, AChE, and α-glycosidase.
