Antischistosomal properties of aurone derivatives against juvenile and adult worms of Schistosoma mansoni

Schistosomiasis is a neglected disease caused by helminth flatworms of the genus Schistosoma, affecting over 240 million people in more than 70 countries. The treatment relies on a single drug, praziquantel, making urgent the discovery of new compounds. A

Synthesis of structurally diverse biflavonoids

Synthetic biflavonoids are associated with interesting biological activities, yet they remain poorly explored within drug discovery. Recent years have witnessed a growing interest in synthetic approaches that can provide access to structurally novel biflavonoids so that the biological usefulness of this compound class can be more fully investigated. Herein, we report upon the exploration of strategies based around Suzuki-Miyaura cross-coupling and alcohol methylenation for the synthesis of two classes of biflavonoids: (i) rare ‘hybrid’ derivatives containing flavonoid monomers belonging to different subclasses, and (ii) homodimeric compounds in which the two flavonoid monomers are linked by a methylenedioxy group. Application of these strategies enabled the preparation of a structurally diverse collection of novel biflavonoids from readily-available starting materials, thereby facilitating the probing of uncharted regions of biologically interesting chemical space.

1-Azaaurones derived from the naturally occurring aurones as potential antimalarial drugs

We report the synthesis and in vitro antiplasmodial activity of 35 compounds, designed as analogues of the naturally occurring aurones. Several of these analogues showed submicromolar antimalarial activity against a chloroquine-resistant strain of Plasmodium falciparum (FcB1-Columbia strain) cultured on human erythrocytes. Substitution of the intracyclic oxygen in aurones by a nitrogen atom and systematic variation of the substituent at the B-ring revealed promising leads showing good activity on the CQ-resistant strain. In particular, 4,6-dimethoxy-4′-ethylazaaurone 22 showed antiplasmodial potency without noticeable toxicity. The easy synthesis of this family of compounds and the relevant antiplasmodial activity are in favor of promising candidates for further development.

4-Hydroxy-6-methoxyaurones with high-affinity binding to cytosolic domain of P-glycoprotein

A series of 4-hydroxy-6-methoxyaurones and 4,6-dimethoxyaurones has been synthesised and tested for their binding affinity toward the nucleotide-binding domain of P-glycoprotein, an ABC (ATP-Binding Cassette) transporter which mediates the resistance of cancer cells to chemotherapy. These compounds differ from each other by the nature of the substituent on the aurone B-ring. The binding affinity seems to be linked to the nature of the substituent, as well as to the presence or the absence of a hydroxy group at position 4. The most active compounds were 4′-bromo-4-hydroxy-6-methoxyaurone and 4-hydroxy-4′-iodo-6-methoxyaurone.

An efficient synthesis of 4,6 dimethoxyaurones

4,6-Dimethoxybenzofuran-3(2H)-one was synthesized in two steps starting from phloroglucinol and used as a useful starting block for the synthesis of aurones by condensation with benzaldehyde derivatives.
