According to the pharmacophore combination principle, a set of new 3′,4′,5′-trimethoxy flavonoid salicylate derivatives were designed, synthesized, and evaluated for biological activity. The cytotoxicity evaluation revealed that compound 10v exhibited higher potency than 5-Fu against HCT-116 cells. Preliminary biological activity studies showed that compound 10v could inhibit the colony formation and migration of HCT-116 cells. Besides, the Hoechst 33258 staining assay and flow cytometry revealed that treatment with compound 10v induced the apoptosis of HCT-116 cells in a concentration-dependent manner, while it had no effect on their cell cycle. The WB analysis suggested that HIF-1α, tubulin, HK-2, and PFK might be the potential pharmacophore targets of compound 10v. Tubulin was a potential drug target for compound 10v, which was explained by analyzing the crystal structure of compound 10v complexed with tubulin. These results indicated that compound 10v might be a promising anti-tumor agent candidate, deserving further optimization and evaluation.

The invention relates to the technical field of medicines, and designs and synthesizes a novel A cyclotrimethoxy 4'-hydroxyflavone compound and an A cyclotrimethoxone-substituted salicylate compound. The figure 1 is a general formula of the A cyclotrimethoxone-substituted salicylate compound, wherein in the formula, R1, R2 and R3 are equal to OCH3 or R2, R3 and R4 are equal to OCH3; R5- is equal to OCH3, CH3, F, Cl, Br, I or the like. The novel A cyclotrimethoxy 4'-hydroxyflavone compound and the A cyclotrimethoxone-substituted salicylate compound can have an obvious inhibiting effect on MGC-803 (human gastric carcinoma cells), HepG2 (human hepatoma carcinoma cells), MCF-7 (human breast cancer cells) and hopefully become anti-tumor drugs. The invention discloses a preparation method of the novel A cyclotrimethoxy 4'-hydroxyflavone compound and the A cyclotrimethoxone-substituted salicylate compound.

Anacardic acid derivatives exhibit a broad range of biological activities. In this report, an efficient method for the synthesis of anacardic acid derivatives was explored, and a small set of salicylic acid variants synthesised retaining a constant hydrophobic element (a naphthyl tail). The naphthyl side chain was introduced via Wittig reaction and the aldehyde installed using directed ortho-metalation reaction of the substituted o-anisic acids. The failure of ortho-metalation using unprotected carboxylic acid group compelled us to use directed ortho-metalation in which a tertiary amide was used as a strong ortho-directing group. In the initial route, tertiary amide cleavage during final step was challenging, but cleaving the tertiary amide before Wittig reaction was beneficial. The Wittig reaction with protected carboxylic group (methyl ester) resulted in side-products whereas using sodium salt resulted in higher yields. The novel compounds were screened for antibacterial activity and cytotoxicity. Although substitution on the salicylic head group enhanced antibacterial activities they also enhanced cytotoxicity.
