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.

2-Octylsuccinic acid and its copolyanhydrides with sebacic acid have been synthesized by melt polycondensation, and were characterized by Fourier transform infrared spectroscopy, 1H NMR, gel permeation chromatography, differential scanning calorimetry, and thermal gravimetric analysis. In vitro studies showed that all copolymers are degradable in phosphate buffer at 37°C. The release profiles of the hydrophilic model drug ciprofloxacin hydrochloride follow first-order release kinetics. CSIRO 2008.

A simple and efficient method has been developed for the synthesis of α-bromoesters and ketones from β-ketoesters and diketones in one pot using a supported reagents system, CuBr2/Al2O 3-Na2CO3/Al2O3, in which β-ketoester reacts first with CuBr2/Al2O3 and the product, α-bromo-β-ketoester, reacts with Na 2CO3/Al2O3 to give the final product, α-bromoesters in good yields.
Unnatural nucleosides and nucleotides. III. Preparation of 2-14C and 4-14C labelled 5-alkyluracils and 5-alkyl-2'-deoxyuridines

2-14C Labelled 5-alkyluracils were prepared by condensation of the diethylacetals of α-formyl-carbonic acid esters with 14C-thiourea. Compounds labelled at 4-C were synthesized by condensation of the labelled carboxylic acid derivatives with thiourea. β-Anomers of 5-alkyl-2'-deoxyuridines were obtained in a fairly good radiochemical yield. Alkyl substituents ranged from methyl to tetradecyl, isopropyl and tert-butyl.
