Bicycloalkanes are well-known isosteres of alkynes and aromatic rings and their use in the field of medicinal chemistry and drug discovery has been on the rise in the past ten years. Herein, we report the modular and practical synthesis of bicycloalkane-containing fragments using nickel-photoredox catalysis. The comparison of their relevant physical-chemical properties with their aromatic counterparts
A series of 3-benzyloxy-1-aza-9-oxafluorenes has been synthesized and biologically evaluated as novel MDR modulators. The concentration dependent inhibition of the efflux pump ABCB1 (P-glycoprotein) has been characterized and is discussed in relation to calculated lipophilicity data. Instead of the molecular lipophilicity the exact positioning of functional groups was found decisive for the biological activities.
