Bis[(para-methoxy)benzyl] phosphonate prodrugs with improved stability and enhanced cell penetration
摘要:
A series of substituted bis[(para-methoxy)benzyl] (bisPMB) esters of 1-naphthalenemethylphosphonate (NMPA) were synthesized and evaluated as phosphonate prodrugs. BisPMB NMPA esters (4b and 4c) with significantly improved aqueous stability were identified that also resulted in increased intracellular levels of NMPA following prodrug incubation with primary rat hepatocytes.

Inhibition of purple acid phosphatase with α-alkoxynaphthylmethylphosphonic acids
摘要:
Purple acid phosphatases (PAPs) are binuclear hydrolases that catalyse the hydrolysis of a range of phosphorylated substrates. Human PAP is a major histochemical marker for the diagnosis of osteoporosis. In patients suffering from this disorder, PAP activity contributes to increased bone resorption and, therefore, human PAP is a key target for the development of anti-osteoporotic drugs. This manuscript describes the design and synthesis of derivatives of 1-naphthylmethylphosphonic acids as inhibitors of PAP. The K(i) values of these compounds are as low as 4 mu M, the lowest reported to date for a PAP inhibitor. (C) 2008 Elsevier Ltd. All rights reserved.

Luminescent lanthanide complexes have been prepared by exploiting the interaction between lanthanide DO3A complexes and chromophore bearing carboxylates or phosphonates. This interaction can be utilised to probe the choice of sensitising chromophore suited to a given lanthanide. Furthermore, ternary complexes obtained from chromophore appended carboxylates dissociate in the presence of phosphate, while those obtained from phosphonates do not.

Reaction of cobalt salts with phosphonic acids in the presence of 6-chloro-2-hydroxypyridine as a co-ligand, normally in its deprotonated form, leads to a series of new polymetallic cobalt cages. The most common structural type is a Co(14)} cage which resembles a fragment of cobalt hydroxide. Variation of the phosphonate present and the cobalt salt leads to Co(6)}, Co(8)}, Co(10)}, Co(11)}, Co(12)}

The present invention relates to mononucleoside phosphate compounds that have the benefits of a dinucleotide pharmaceutical. These mononucleoside phosphates can be made from a mononucleotide that has been modified by attaching a degradation resistant substituent on the terminal phosphate of a polyphosphate mononucleotide. By attaching this degradation resistant substituent, the stability from degradation matches or exceeds those of certain dinucleotides.
