A study on in vitro enzyme inhibitory properties of Asphodeline anatolica: New sources of natural inhibitors for public health problems
Scopus
Toplam 133 atıf DOI
Asphodeline species are traditionally used as food and medicines. The different extracts (acetone, methanol and water) from different parts (stem, root, seed and leaf) of Asphodeline anatolica were screened for inhibitory potentials on cholinesterase, tyrosinase, α-amylase and α-glucosidase. Enzyme inhibitory effects were investigated by using microplate reader. All studied extracts exhibited remarkable inhibitory effects on the tested enzymes. Generally, acetone and methanol extracts have higher potentials than water extracts. Also, the enzyme inhibitory activities of the extracts varied significantly according to the plant parts as well as the solvent used. R-Met (7.42. mgGALAEs/g extract) and St-Ac (10.74. mgGALAEs/g extract) had the highest acetylcholinesterase and butrylcholinesterase inhibitory activity, respectively. R-Met (22.48. mgKAEs/g extract) exhibited the strongest tyrosinase inhibitory effects, while Se-Ac had the most potent activity on both α-amylase (2.53. mmolACAEs/g extract) and α-glucosidase (6.70. mmolACAEs/g extract). The results suggested that the A. anatolica extract may be useful for food and medicinal applications.

The antioxidant and enzyme inhibitory potential of fifteen cycloartane-type triterpenes’ potentials were investigated using different assays. In the phosphomolybdenum method, cycloalpio-side D (6) (4.05 mmol TEs/g) showed the highest activity. In 1,1-diphenyl-2-picrylhydrazyl (DPPH*) radical and 2,2′-azino-bis(3-ethylbenzothiazoline)-6-sulfonic acid (ABTS) cation radical scavenging as-says, cycloorbicoside A-7-monoacetate (2) (5.03 mg TE/g) and cycloorbicoside B (10) (10.60 mg TE/g) displayed the highest activities, respectively. Oleanolic acid (14) (51.45 mg TE/g) and 3-O-β-D-xylopyranoside-(23R,24S)-16β,23;16α,24-diepoxycycloart-25(26)-en-3β,7β-diol 7-monoacetate (4) (13.25 mg TE/g) revealed the highest reducing power in cupric ion-reducing activity (CUPRAC) and ferric-reducing antioxidant power (FRAP) assays, respectively. In metal-chelating activity on ferrous ions, compound 2 displayed the highest activity estimated by 41.00 mg EDTAE/g (EDTA equiva-lents/g). The tested triterpenes showed promising AChE and BChE inhibitory potential with 3-O-β-D-xylopyranoside-(23R,24S)-16β,23;16α,24-diepoxycycloart-25(26)-en-3β,7β-diol 2′,3′,4′,7-tetraacetate (3), exhibiting the highest inhibitory activity as estimated from 5.64 and 5.19 mg GALAE/g (galan-tamine equivalent/g), respectively. Compound 2 displayed the most potent tyrosinase inhibitory activity (113.24 mg KAE/g (mg kojic acid equivalent/g)). Regarding α-amylase and α-glucosidase inhibition, 3-O-β-D-xylopyranoside-(23R,24S)-16β,23;16α,24-diepoxycycloart-25(26)-en-3β,7β-diol (5) (0.55 mmol ACAE/g) and compound 3 (25.18 mmol ACAE/g) exerted the highest activities, respectively. In silico studies focused on compounds 2, 6, and 7 as inhibitors of tyrosinase revealed that compound 2 displayed a good ranking score (−7.069 kcal/mole) and also that the ∆G free-binding energy was the highest among the three selected compounds. From the ADMET/TOPKAT prediction, it can be concluded that compounds 4 and 5 displayed the best pharmacokinetic and pharmacodynamic behavior, with considerable activity in most of the examined assays.
