Abstract

Chromene derivatives with manifold structural framework and pharmacological properties were ubiquitous in the mollusks of marine origin. A previously undescribed 1H-benzochromenone was isolated through bioassay-guided chromatographic purification of the organic extract of the marine gastropod mollusk Chicoreus ramosus. The compound was characterised as 6-(20,20- dimethyl)-30-en-10-yl-10-oxy)-3-hydroxy-1H-benzo[c]chromene- 2(10aH)-one based on integrated spectroscopic analysis. The antioxidant studies by employing the stable free radicals reported that the antioxidant activity (IC50 1.4–1.6 mM) was comparable to a-tocopherol (IC50 1.4–1.7 mM). The attenuating potential of the studied compound against pro-inflammatory 5-lipoxygenase (IC50 2.12 mM) was significantly greater than that exhibited by antiinflammatory drug ibuprofen (IC50 4.4 mM), whereas its inhibitory properties against carbolytic a-amylase (IC50 �0.72 mM) was comparable with that displayed by acarbose (IC50 0.43 mM). The present study recognised the potential of 1H-benzochromenone derivative isolated from C. ramosus as important pharmaceutical lead with anti-diabetic and anti-inflammatory potentials to reduce the risk of hyperglycaemia and inflammatory pathologies.
