Myocardial infarction (MI) is defined as the deprivation of the myocardial tissue of oxygen and nutrients, resulting in the induction of inflammation and apoptosis of the cardiomyocytes. Poly (ADP‑ribose) polymerase 1 (PARP1) is a nuclear enzyme closely associated with MI, that can be activated by DNA damage. Inducible nitric oxide synthase (iNOS) is a critical enzyme among the inflammatory cyt...

At present ethylenediamine is one of the more studied nitrogen— —ligands. The main physico—chemical properties of this diamine are reported in this survey. The fundamental techniques for its purification and storage and its acid—base characteristics in aqueous solution are described. The formation constants of the complexes with various metal ion, the thermodyna mic values relative to the react...

A novel, mixed-valent copper(I)-copper(II) complex, {[bis(ethylene-diamine)copper(II)] bis[diiodocuprate(I)]} (1), has been prepared by electrochemical dissolution of a sacrificial copper anode in a solution of ethylenediamine (en), I2 and tetraethylammoniumperchlorate (TEAP) as supporting electrolyte in acetonitrile (AcN)and characterized by single-crystal X-ray structure determination. The cr...

Trimetazidine dihydrochloride, a cellular antiischemic agent indicated in the management and prophylaxis of angina pectoris is given as 20 mg thrice daily in the conventional dosage regimen. The purpose of the present study was to formulate and evaluate twice a day extended release tablets containing 30 mg trimetazidine dihydrochloride. The method developed to formulate these extended release t...

We have previously demonstrated that metal oxide ultrathin films, by themselves, can produce imprinted cavities for organic molecules. In the present study, memorization of the coordination environments of metal ions was achieved by incorporation of diamine chelating ligands in thin films of metal oxides. The films imprinted with Cu2+ or Zn2 + showed selective binding to the template over the c...

The reaction of 1-oxo-1,2,3,4-tetrahydrocarbazoles (1a-e) with paraformaldehyde and ethylenediamine yielded N,N'-bis(1,2,3,4-tetrahydrocarbazol-1-ylidene)ethane-1,2-diamines (2a-e). Here, like in another similar attempt of replacing ethylenediamine by ethanolamine, ended up in formation of 2-{[1-(2-(2-aminoethoxy)ethylimino)-1,2,3,4-tetrahydrocarbazol-2-yl-methyl]amino}ethanols (3a-e). These pr...

Sapropterin dihydrochloride is used to lower blood phenylalanine levels in tetrahydrobiopterin-responsive phenylketonuria in conjunction with a phenylalanine-restricted diet. This study investigated the solubility and stability of sapropterin tablets and a sapropterin powder formulation when mixed in selected beverages and foods. Solubility was partial for the tablets and complete for the powde...

Treatment-related Myelodysplastic Syndrome (t-MDS) is well known and serious complication of cancer treatment. However, MDS cases caused by therapy of common nonmalignant diseases are unusual and represent diagnosic and therapeutic challenge. We experienced a case of secondary MDS, possibly induced by trimetazidine dihydrochloride, which was spontaneously resolved by discontinuance of the drug....
