Natural and synthetic benzophenones: interaction with the cytosolic binding domain of P-glycoprotein
摘要:
A benzophenone glycoside has been isolated from Davallia solida. Its: structure was elucidated by chemical and spectral means as 4-0-beta -D-glucopyranosyl-2,6,4'-trihydroxybenzophenone. It bound with moderate affinity to the purified C-terminal cytosolic domain of P-glycoprotein. but the binding affinity was 6- to 10-fold increased for its aglycone derivative and other related benzophenones.

An efficient and concise syntheticroute for biologically interesting polycycles bearing citran and chalcone nuclei was developed starting from a variety of trihydroxybenzenes with substituents on the ring. The key strategies involved an ethylenediamine diacetate-catalyzed cyclization by a domino aldol-type/electrocyclization/H-shift/hetero Diels–Alder reaction of trihydroxybenzenes and citral or trans
