The purpose of the present study was to determine the acute effects of the anticraving compound acamprosate (calcium acetylhomotaurinate) and the closely related compound homotaurine on ethanol intake and ethanol-stimulated dopamine release in the nucleus accumbens. Male rats were treated with acamprosate (200 or 400 mg/kg intraperitoneally, i.p.) or homotaurine (10, 50, or 100 mg/kg i.p.) 15 m...

Citicoline and homotaurine are renowned compounds that exhibit potent neuroprotective activities through distinct molecular mechanisms. The present study was undertaken to demonstrate whether cotreatment with citicoline and homotaurine affects cell survival in primary retinal cultures under experimental conditions simulating retinal neurodegeneration. Primary cultures were obtained from the ret...

Homotaurine (3-aminopropanesulfonate), a natural product and an analogue of GABA (4-aminobutyrate), was found to be a sole source of nitrogen for Cupriavidus necator (Ralstonia eutropha) H16, whose genome sequence is known. Homotaurine nitrogen was assimilated into cell material, and the quantitative fate of the organosulfonate was sulfopropanoate, which was recovered in the growth medium. The ...

Current treatment options for patients with Alzheimer's disease (AD) are limited at providing symptomatic relief, with no effects on the underlying pathophysiology. Recently, advances in the understanding of the AD pathogenesis highlighted the role of ABeta (Aβ) oligomers particularly interfering with mechanisms of cortical plasticity such as long-term potentiation (LTP) and long-term depressio...

Due to the progressive aging of the population and to the age-associated increase in its incidence, Alzheimer's disease (AD) will become in near future one of the major challenges that healthcare systems will have to face with in developed countries. Since the pathophysiological process of AD is thought to begin many years before the clinical diagnosis of dementia, in theory there is an opportu...

Homotaurine (3-aminopropanesulfonate), free or derivatized, is in widespread pharmaceutical and laboratory use. Studies with enrichment cultures indicated that the compound is degradable as a sole source of carbon or as a sole source of nitrogen for bacterial growth. A pure culture of Burkholderia sp. was isolated which assimilated the amino group from homotaurine in a glucose-salts medium, and...

PURPOSE Retinal ganglion cell (RGC) death is the final event leading to visual impairment in glaucoma; therefore, identification of neuroprotective strategies able to slow down or prevent the process is one of the main challenges for glaucoma research. The purpose of this study was to evaluate the neuroprotective potential of RGC death induced by the in vivo transient increase in intraocular pr...

Background and objectives: According to recent studies, homotaurine may be an Alzheimer's active ingredient. The goal of this project was to extract and detect homotaurine in algae collected from Persian Gulf shores. Methods: Extraction was done with etanol 80% for 30 min in ambient temperature. The HPLC elution solvent required a mixture of two solvents. Solve...

CAMPRAL (acamprosate calcium) is supplied in an enteric-coated tablet for oral administration. Acamprosate calcium is a synthetic compound with a chemical structure similar to that of the endogenous amino acid homotaurine, which is a structural analogue of the amino acid neurotransmitter γ-aminobutyric acid and the amino acid neuromodulator taurine. Its chemical name is calcium acetylaminopropa...
