The invenetion relates to a preparation method of a ternary surface active agent adopting 1,1,1-tri(hydroxymethyl) ethane as a link group. A structural formula of the ternary surface active agent is as follows (described in specifications). The synthesis method includes a synthesis step of alpha-bromo-carboxylic acid, an esterification reaction step of the link group 1,1,1-tri(hydroxymethyl) ethane and an esterolysis reaction step. The synthesis process condition of the ternary surface active agent is as follows: 30% NaOH and tetrahydrofuran are used as a solvent to be subjected to reflux reaction for 5 to 7 hours.

Phosphonocarboxylate (PC) analogs of the anti-osteoporotic drugs, bisphosphonates, represent the first class of selective inhibitors of Rab geranylgeranyl transferase (RabGGTase, RGGT), an enzyme implicated in several diseases including ovarian, breast and skin cancer. Here we present the synthesis and biological characterization of an extended set of this class of compounds, including lipophilic derivatives of the known RGGT inhibitors. From this new panel of PCs, we have identified an inhibitor of RGGT that is of similar potency as the most active published phosphonocarboxylate, but of higher selectivity towards prenyl pyrophosphate synthases. New insights into structural requirements are also presented, showing that only PC analogs of the most potent 3rd generation bisphosphonates inhibit RGGT. In addition, the first phosphonocarboxylate-derived GGPPS weak inhibitor is reported.
