Here, we found a natural compound, embonic acid (EA), that can specifically inhibit the enzymatic activity of mitochondrial NAD(P)+-dependent malic enzyme (m-NAD(P)-ME, ME2) either in vitro or in vivo. The in vitro IC50 value of EA for m-NAD(P)-ME was 1.4

In a search for an infarct avid tracer agent with improved properties, we have observed that bis-DTPA derivatives of pamoic acid have a high avidity for necrotic tissue. Here, we report the synthesis, radiolabeling, and preliminary evaluation in normal mice

The dissolution behaviour of slightly water-soluble embonic acid salts of ampicillin and amoxycillin was studied quantitatively as a function of solution pH (1.15-8.00) using the rotating disk method combined with reversed-phase high-performance liquid chromatography. The dissolution rate of ampicillin embonate

Pamoic acid is used as a counter ion to obtain long-acting pharmaceutical formulations of certain basic drugs. In order to investigate the pharmacokinetics of pamoic acid, a simple, sensitive and reliable method has been established for the quantitative determination of

In this study, we labeled N,N'-bis(diethylenetriamine pentaacetic acid)-pamoic acid bis-hydrazide (bis-DTPA-PA) with the generator produced PET radionuclide gallium-68 and evaluated 68Ga-bis-DTPA-PA as a potential tracer for in vivo visualization of necrosis by positron emission tomography (PET). Radiolabeling was achieved with
