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

Known agonists of the orphan receptor GPR35 are kynurenic acid, zaprinast, 5-nitro-2-(3-phenylproplyamino) benzoic acid, and lysophosphatidic acids. Their relatively low affinities for GPR35 and prominent off-target effects at other pathways, however, diminish their utility for understanding GPR35 signaling and for
A series of four-connected entangled metal-organic frameworks assembled from pamoic acid and pyridine-containing ligands: interpenetrating, self-penetrating, and supramolecular isomerism.

DNA polymerase beta (beta-pol) plays a central role in repair of damaged DNA bases by base excision repair (BER) pathways. A predominant phenotype of beta-pol null mouse fibroblasts is hypersensitivity to the DNA-methylating agent methyl methanesulfonate. Residues in the 8-kDa

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

Many pharmacological agents include "inactive" constituents that are used to alter the solubility, stability, or pharmaceutical properties of a drug. These "salts" are often ignored, and the "active ingredient" gets all of the attention. Pamoic acid (4-[(3-carboxy-2-hydroxynaphthalen-1-yl)methyl]-3-hydroxynaphthalene-2-carboxylic acid) has been

Long-acting injectables (LAIs) are increasingly recognized as an effective therapeutic approach for treating chronic conditions. Many LAIs are formulated to create a poorly soluble depot from which the active agent is delivered over time. This long residing depot can cause

We present an in situ hydrophobic salt forming technique for the encapsulation of weakly hydrophobic, ionizable active pharmaceutical ingredients (API) into stable nanocarriers (NCs) formed via a rapid precipitation process. Traditionally, NC formation via rapid precipitation has been difficult with

Human IGR1 cells are a model for malignant melanoma. Since progression through the cell cycle is accompanied by transient cell hyperpolarization, we studied the properties of potassium and chloride ion channels and their impact on cell growth. The major potassium

The ever-expanding knowledge of the role of p53 in cellular metabolism, apoptosis, and cell cycle control has led to increasing interest in defining the stress response pathways that regulate Mdm2. In an effort to identify novel Mdm2 binding partners, we

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
