Phosphonate, phosphinate, and phosphate groups carry one or two negative charges at physio-logical pH values making them very polar (Figure 1). This high polarity is the basis for many deficiencies in terms of drug ...
WebDimethyl phosphonate (DMP) is rapidly absorbed via the oral and dermal routes. The main metabolic pathway in rodents is demethylation to monomethyl hydrogen phosphite (MMP) and further oxidation to CO 2. DMP was mainly eliminated via urine and expired air. Over the studied dose range between 10 and 200 mg/kg bw and 5 x WebMar 1, 2002 · Phosphonate compounds have a direct C-P bond and can strongly bind to clay minerals.
