Synthesis of Cis-Diammine (1,1-cyclobutane dicarboxylate) Platinum(II)

Platinum-based anticancer drugs are chemotherapeutic agents to treat cancer. Carboplatin (cis diammine cyclobutane dicarboxylate platinum (II)) is a second generation drug that has less toxic than cisplatin, allowing for high dosages. In the first stage, 1,3-Cyclobutane dicarboxylic acid, a key intermediate for the preparation of carboplatin, have been synthesized in good yields using diffe...

Nanomagnetic organic-inorganic hybrid (CuFe2O4@Si-Imid-PMo): an efficient green catalyst for the synthesis of 2,4,5-trisubstituted imidazoles

In this research, a new magnetic nanocatalyst CuFe2O4@Si-Imid-PMo containing acidic ionic liquid based on imidazolium cation and phosphomolybdic acid anion immobilized on CuFe2O4@SiO2 magnetic nanoparticles was prepared and characterized using FT-IR, EDX, SEM, and VSM techniques. Then, the catalytic activity of CuFe2O4@Si-Imid-PMo was evaluated in the synthesis of 2,4,5-trisubstituted imidazole...

Immobilization of Phosphomolybdate Anions on the Surface of Magnetite Nanoparticles Modified with Quaternary Phosphonium Cations

A new hybrid nanomaterial was developed by immobilization of phosphomolybdate anions on the surface of modified magnetite nanoparticles with quaternary phosphonium cations. Silica coated magnetic nanoparticles supported phosphonium cations, Ph3P+-SCMNPs, were prepared by covalent attachment of chloropropylsilyl groups on the surface of silica coated magnetite nanoparticles...

Terbium Sensitized Chemiluminescence Method for the Determination of Rabeprazole -Application to Pharmaceutical Analysis and Dissolution Studies

A simple and sensitive chemiluminescence-based method was established for the determination of rabeprazole.The proposed method was based on the enhancing effect of rabeprazole on Ce(IV)-Na2SO3 -Tb(III) chemiluminescence reaction. A possible mechanism was discussed for chemiluminescence system by studying UV-Vis, fluorescence and chemiluminescence spectra. The effects of va...
