Quercetin derivative and its preparation method and application

The invention discloses a quercetin derivative and a preparation method and application thereof. The preparation method comprises the following steps: firstly using dichlorodiphenylmethane to protect quercetin o-diphenol hydroxyl, combining a benzyl protection group to obtain the selectively protected quercetin derivative, and then independently reacting with dimethyl sulfate, diethyl sulfate, allyl bromide, paratoluensulfonyl chloride and acetic anhydride respectively to generate corresponding quercetin derivatives. All of the prepared derivative compounds have NRK-49F proliferation activity inhibition superior to that of quercetin. The quercetin derivatives 20a-1, 14a-1 and 23d-1 compositely replaced by methyl and p-tosyl have higher inhibition NRK-49F proliferation activity, and the inhibition ratio respectively reaches 86.33%, 78.04% and 75.91%. Thus, the currently obtained quercetin derivative compounds have obvious inhibition effect on kidney fibroblast NRK-49F proliferation.

Metabolism-based synthesis, biologic evaluation and SARs analysis of O-methylated analogs of quercetin as thrombin inhibitors

In blood, quercetin is mainly found in metabolized forms. In order to study the activities of these quercetin metabolites in cardiovascular disease, 17 methylquercetin derivatives were synthesized based on metabolism in vivo, their thrombin inhibition activity were evaluated through the analyzation of prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT) and fibrinogen (FIB). The results showed that 6 methylquercetin derivatives had stronger inhibitory activities than that of quercetin. Preliminary SARs analysis showed that hydroxyl groups at C-3′ and C-4′ position in the B-ring and hydroxyl group at C-3 position in the C-ring played key roles in the thrombin inhibitory activity. The findings of this study would provide information for the exploitation and utilization of quercetin as thrombin inhibitor for thrombotic disease treatment.
