One novel triterpene cycloartane-type, named hirtinone (1), six protolimonoids - nilocitin (2), dihydronilocitin B (3), melianone epimers (4) and (5), piscidinol A (6) and melianone lactone (7), one tertranortriterpenoid, hirtin (8), and one sesquiterpene, spathulenol (9), were identified in the fruits of Trichilia hirta. The structures were established by 1D and 2D NMR (1H and 13C-NMR, DEPTQ, ...

a copolymer of styrene and methyl styrene was synthesized by nitroxide - mediated “living” free radical polymerization )nmp). n-bromosuccinimide was used as a brominating agent to obtain a copolymer with bromine as its end group. this brominated copolymer was used as macro initiators for atom transfer  radical  polymerization  (atrp).  chemical  modifcation  of  the  clay  and transformation of...

Synthesis of 2’,4’-dihydroxy-3,4-dimethoxychalcone and in vitro test its sunscreen activity have been carried out. Chalcone was synthesized from 3,4-dimethoxybenzaldehyde 2,4-dihydroxyacetophenone through Claisen-Schmidt condensation. The synthesis performed by using KOH 40% under stirring at room temperature for 48 h. compounds characterized FTIR, GC-MS 1H NMR spectrometers. Further, the chalc...

An anti-tumor compound as N3-{phenyl [(4-pyridylcarbonyl) amino] methyl} weresynthesized and identified (NPPA). Fe (III), Co(II) and Pd(II) metal complexes of this ligand preparedby reaction of chloride salt of Fe (III), Co(II) and Pd(II) with NPPA in dry acetonitrile. Identification andCharacterization of the ligand was performed by FT-IR, 1H-NMR spectroscopy and elemental an...

Two Cd complexes have been prepared by reaction of Cd (II) with 4-(1H-Tetrazol-5yloxy) – phenylamine (HTY) and 2-(1H-Tetrazol) pyridine (HTP) ligands. These new complexes were characterized by IR, UV-Visible, 1H-NMR and 13C-NMR spectroscopies. The changes observed between the FT-IR, H-NMR and UV-Vis spectra of the ligands and complexes allowed to establish the coordination mode of the metal in ...
