, p. 6281 - 6284 (2007/10/03)
A mild and rapid protocol for cleavage of phosphate, phosphonate and phosphoramide esters. The scope and limitations of this microwave-assisted reaction is explored here.
Materials comprising organic groups containing sulphur and phosphorous bonded to a mineral oxide via oxygen atoms
-
Page/Page column 2, (2008/06/13)
The invention describes materials comprising organic groups containing sulphur and phosphorous bonded together by a hydrocarbon chain and bonded via phosphorous and oxygen atoms to a mineral oxide of an element M, said materials being characterized in that they comprise M-O-M′ bonds, M′representing an element of a mineral oxide identical to or different from M, in that the ratio of the element M to the phosphorous is about 0.5: 1 to about 500:1 and in that each phosphorous atom of the phosphorous-containing groups forms at least one P—O-M bond and/or P—O-M′ bond. The invention also describes a process for preparing such materials.
Diaryl ester prodrugs of FR900098 with improved in vivo antimalarial activity
Reichenberg, Armin,Wiesner, Jochen,Weidemeyer, Claus,Dreiseidler, Erhard,Sanderbrand, Silke,Altincicek, Boran,Beck, Ewald,Schlitzer, Martin,Jomaa, Hassan

The fosmidomycin derivative FR900098 represents an inhibitor of the 1-deoxy-D-xylulose 5-phosphate (DOXP) reductoisomerase with potent antimalarial activity. Prodrugs of FR900098 with increased activity after oral administration were obtained by chemical modification of the phosphonate moiety to yield phosphodiaryl esters. One diaryl ester prodrug demonstrated efficacy in mice infected with the rodent malaria parasite Plasmodium vinckei comparable to ip drug administration.
