methyl brevifolincarboxylate Usage And Synthesis

Uses

Methyl brevifolincarboxylate (Brevifolincarboxylic acid methyl ester) is a potent influenza virus PB2 cap-binding inhibitor. Methyl brevifolincarboxylate has anti-oxidant activity. Methyl brevifolincarboxylate also inhibits platelet aggregation, lipid metabolism and inflammation[1][2][4][5][6].

Definition

ChEBI: An organic heterotricyclic compound that is 1,2,3,5-tetrahydrocyclopenta[c]isochromene substituted by hydroxy groups at positions 7, 8 and 9, oxo groups at positions 3 and 5 and a methoxycarbonyl group at position 1. Isolated from Phyll nthus urinaria and Phyllanthus niruri, it exhibits vasorelaxant activity.

Synthesis

Extraction method of short-leaf hematoxylin methyl ester: take dry leaves under the beads of the whole grass, beaten into coarse powder, placed into the Sojitz extractor, first add petroleum ether degreasing, the dregs of the drug cool dry, and then fully extracted with methanol. Separate the methanol extract, concentrated methanol extract with reduced pressure distillation, to get methanol extract. This extract was mixed with appropriate amount of water, and then sequentially distributed with chloroform and n-butanol, n-butanol was taken out and concentrated under reduced pressure, and then mixed with silica gel and diatomaceous earth, silica gel low-pressure column chromatography, and then chloroform-methanol-water was used as the gradient elution, and the eluates were collected separately, and each portion of 250 ml was obtained as the 36th portion of the crude product of short-leafed Succinum sativum phenolic acid methyl ester. The crude product was then purified by silica gel column for the second time, and recrystallized with methanol-chloroform to obtain pure methyl short-leaf thujaplichenate.
