| Description | Ethyl orsellinate is a lichen metabolite and a derivative of lecanoric acid (Item No. 22710) that has antiproliferative activities.1,2 It inhibits the proliferation of human Hep-2 larynx carcinoma, MCF-7 breast cancer, and 786-0 kidney carcinoma cells, as well as B16-F10 murine melanoma and non-cancerous Vero cells (IC50s = 31.2, 70.3, 47.5, 64.8, and 28.1 µg/ml, respectively).2 Ethyl orsellinate is toxic to brine shrimp (A. salina) with an LC50 value of 495 µM.3WARNING This product is not for human or veterinary use. | | Definition | ChEBI: 2,4-dihydroxy-6-methylbenzoic acid ethyl ester is a 4-hydroxybenzoate ester. | | General Description | Ethyl 2,4-dihydroxy-6-methylbenzoate is also referred as ethyl orsellinate. It was isolated from chloroform extract of Peltigera aphthosa. It is one of the product formed during alcoholyses of lecanoric acid. | | Synthesis | The stem bark of Illicium difengpi (5.0kg) was powdered and extracted three times with aqueous ethanol (ethanol/water 8:2) under reflux. The solvent was then evaporated under reduced pressure to obtain a dry residue (150g). The residue was suspended in water (2L) and extracted successively with petroleum ether (3 × 2L), EtOAc (3 × 2L) and BuOH (3 × 2L), affording 5g, 70g, and 40g, respectively, of each dried fraction. The EtOAc fraction was subjected to silica gel column chromatography using gradient elution (CH2Cl2/CH3OH, 200:1 to 2:1, v/v) to give four main fractions, of which was purified by successive silica gel column chromatography (CH2Cl2/CH3OH, 100:1→20:1); 2,4-dihy-droxy-6-methyl-benzoic acid ethyl ester (Ethyl 2,4-dihydroxy-6-methylbenzoate) was obtained from the fraction eluted by CH2Cl2/CH3OH (40:1)[1]. | | Structure and conformation | The mol-ecular structure of Ethyl 2,4-dihydroxy-6-methylbenzoate contains a methyl group, two hydroxyl groups, and a carboeth-oxy group, which are attached to C2, C4, C6 and C7 of the central benzene ring, respectively. An intra-molecular O3—H3···O1 hydrogen bond stabilizes the mol-ecular conformation. In the crystal, O4—H4···O3i and C3—H3A···O4ii hydrogen bonds link the mol-ecules into double strands parallel to the direction. In the solid state, the compound also forms offset slanted stacks of alternating inversion-related mol-ecules along the a-axis direction[1]. | | References | [1] Xiong, Huiping , et al.
