Synthetic Models Related to Furanocoumarin — CYP3A4 Interactions. Synthesis of Furanocoumarin Dimers that Have Inhibitory Effects on Activity of Human CYP3A4
Synthesis of a series of furanocoumarin dimers that have inhibitory effects on the activity of human cytochrome P450 (CYP) 3A4 is described. The reported furanocoumarin dimers paradisins A and B from grapefruit juice showed potent CYP3A4 inhibition with an IC50, value of 0.07 mu M. Synthetic furanocoumarin dimer (10), which is more stable and accessible than paradisins, exhibited comparable activity against CYP 3A4 (IC50 = 0.02 mu M).

A new approach to highly enantioenrichedcycliccompounds (up to 98 % ee) has been developed by using ω-ethylenic allylic substrates in a one-pot asymmetricallylicalkylation and ring-closingmetathesis sequence. The starting compounds are synthetic equivalents of cyclicallylic substrates. The method is exemplified with both Cu and Ir catalysts, and chiral phosphoramidite ligands.
