Developing effective antimicrobial agents: synthesis and molecular docking study of ciprofloxacin-benzimidazole hybrids
(Wiley, 2024)
In this study, we designed and synthesized some new ciprofloxacin-benzimidazole hybrid compounds and evaluated them for their antimicrobial activity against four Gram-positive (B. subtilis, B. megaterium, E. faecalis and ...
Synthesis and spectroscopic studies of homo-binuclear, alkoxo bridged homo- and hetero-tetranuclear metal complexes of a bis-N 2O 4 Schiff base ligand derived from ethanolamine and macroacyclic tetranaphthaldehyde
(Elsevier, 2011)
Three new homo-binuclear Ni(II), Cu(II), Zn(II) complexes (2-4), homo-tetranuclear Cu(II) complex (5), and hetero-tetranuclear Cu(II)-Ni(II) complex (6) of a macroacyclic potentially bis-hexadentate N 2O 4 Schiff base have ...
Experimental and theoretical study on the structure and vibrational spectra of β-2-aminopyridinium dihydrogenphosphate
(Elsevier, 2011)
Experimental and theoretical vibrational spectra of ?-2- aminopyridinium dihydrogenphosphate (?-2APDP) have been investigated. The FT-IR spectrum of ?-2APDP was recorded in the region 4000-400 cm -1. The optimized molecular ...
Structural analysis of naproxen-intercalated bentonite (Unye)
(Elsevier, 2011)
The difference in the basal spacing (8.79Å) and a higher mass loss (6.2%) in the temperature range of 200-750°C of naproxen-bentonite (N-bentonite) comparing to that of Unye bentonite (UB) signified the existence of thermally ...
Silorane-based composite: Depth of cure, surface hardness, degree of conversion, and cervical microleakage in class II cavities
(Wiley, 2011)
Objective: The purpose of this study was to determine the depth of cure, degree of conversion (DC), hardness, and cervical sealing ability of silorane-based composite (Filtek Silorane [FS; 3M, Seefeld, Germany]) and to ...
Synthesis of novel triazol compounds containing isatin as potential antibacterial and antifungal agents by microwave and conventional methods
(Sage Publishing, 2011)
Microwave irradiation has been used to accelerate the conversion of isatin (1a) and 5-nitroisatin (1b) into their Schiff bases 3-[5?-aryl(alkyl)- 2?,4?-dihydro-1?,2?,4?-triazol-3?-on- 4?-yl]iminoisatin (3a-g) and ...
New olefinic centred binuclear clamshell type phthalocyanines: Design, synthesis, structural characterisation, the stability and the change in the electron cloud at olefine-based symmetrical diphthalonitrile fragment by the combined application of UV-Vis electronic structure and theoretical methods
(Elsevier, 2011)
The olefinic centred Schiff base (3) was obtained from the condensation of substituted dialdehyde (1) with 2-amino-4-methylphenol (2) in a 1:2 ratio. The diphthalonitrile derivative (5) was prepared by the reaction of ...
Structural characterization of aniline-bentonite composite by FTIR, DTA/TG, and PXRD analyses and BET measurement
(Taylor & Francis, 2011)
The aniline species incorporated into the acid-activated bentonite matrices leads to the decay of the skeletal stretches centered at 1041 cm-1 and the rise of new features in the phenyl ring frequency region, 1700-1400 ...
Novel coordination polymers of metal(II) succinates with 4-aminopyridine: Synthesis, spectroscopic, thermal, and fluorescent properties
(Wiley, 2011)
Four novel divalent transitional metal succinates (suc) with 4-aminopyridine (apy), [M(apy)2(H2O)2(?-suc) ]n [M = Ni (1), Co (2)] and [M(apy)2(H2O)(suc)] [M = Cu (3), Zn (4)] were synthesized and characterized by elemental ...
Syntheses, crystal structures, fluorescent, and thermal properties of nickel(II) 5,5-diethylbarbiturate complexes with (2-aminomethyl), (2-aminoethyl), and (2-hydroxyethyl)pyridines
(Taylor & Francis, 2011)
Three nickel(II) complexes of 5,5-diethlybarbiturate (barb) with (2-aminomethyl)pyridine (ampy), (2-aminoethyl)pyridine (aepy), and (2-hydroxyethyl)pyridine (hepy), [Ni(barb-N)2(ampy)2] (1), [Ni(barb-N,O)(aepy)2](barb)·H2O ...
