Design and synthesis of non-hydrolyzable homoisoprenoid α-monofluorophosphonate inhibitors of PPAPDC family integral membrane lipid phosphatases

An efficient, diversity oriented synthesis of homoisoprenoid α-monofluorophosphonates utilizing electrophilic fluorination is presented along with their activity as inhibitors of PPAPDC2 family integral membrane lipid phosphatases. These novel phosphatase-resistant analogues of isoprenoid monophosphates are a platform for further structure–activity relationship studies and provide access to other isoprenoid family members where the phosphate ester oxygen is replaced by a α-monofluoromethylene moiety.
