Dryopteris fragrans phloroglucinol compound flavaspidic acid BB and antibacterial application thereof

The invention relates to the technical field of medicine and discloses an antibacterial application of a Dryopteris fragrans phloroglucinol compound flavaspidic acid BB. The invention provides the flavaspidic acid BB obtained by the chemical synthesis method. The flavaspidic acid BB has good antibacterial effects, effectively fills in the application deficiency of the antibacterial natural compound and provides an effective antibacterial solution for drug-resistant bacteria. The experimental results show that the compound has a strong antibacterial effect and good curative effects especially on drug-resistant bacteria.

A natural product yellow filicic acid BB of full-synthesis method

The invention relates to a natural product yellow filicic acid BB of full-synthesis method, which belongs to the technical field of organic chemistry. The invention from the economic and easy to synthesize the phloroglucinol proceed double-acylated phloroglucinol, then after iodine methane-to-carbon double methylation, removing monomolecular acyl got the midbody 3; to phloroglucinol as raw materials, acetate acylation to obtain the aldehyde phloroglucinol, reduction of the aldehyde is methyl, then acylated to obtain intermediate 6; the two fragments obtained through the Eschenmoser's salt combined yellow filicic acid BB. In the method 42% overall yield of yellow filicic acid improves the BB fully synthetic yield, raw material economy are easy, simple operation, high yield, and suitable for production, may be its biological activity study provide a large number of raw materials.
