Abdel-Ghani, N. T., M. S. Rizk, and M. Mostafa, " Extractive determination of ephedrine hydrochloride and bromhexine hydrochloride in pure solutions, pharmaceutical dosage form and urine samples", Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy, vol. 111, pp. 131-141, 2013. Abstract

Simple, rapid, sensitive, precise and accurate spectrophotometric methods for the detn. of ephedrine hydrochloride (E- HCl) and bromhexine hydrochloride (Br-HCl) in bulk samples, dosage form and in spiked urine samples were investigated. The methods are based on the formation of a yellow colored ion-assocs. due to the interaction between the examd. drugs with picric acid (PA), chlorophyllin coppered trisodium salt (CLPH), alizarin red (AR) and ammonium reineckate (Rk) reagents. A buffer soln. had been used and the extn. was carried out using org. solvent, the ion assocs. exhibit absorption maxima at 410, 410, 430 and 530 nm of (Br-HCl)with PA, CLPH, AR and Rk resp.; 410, 410, 435 and 530 of (E-HCl) with PA, CLPH, AR and Rk resp. (E-HCl) and (Br-HCl) could be detd. up to 13, 121, 120 and 160; 25, 200, 92 and 206 µg mL-1, using PA, CLPH, AR and Rk resp. The optimum reaction conditions for quant. anal. were investigated. In addn., the molar absorptivity, Sandell sensitivity were detd. for the investigated drug. The correlation coeff. was ≥0.995 (n = 6) with a relative std. deviation (RSD) ≤1.15 for five selected concns. of the reagents. Therefore the concn. of Br-HCl and E-HCl drugs in their pharmaceutical formulations and spiked urine samples had been detd. successfully.

Comprehensive theor. and exptl. structural studies on N-(4,6-dimethyl-pyrimidin-2-yl)-4-[(2-hydroxy-benzylidene)- amino]benzenesulfonamide (SMS) have been carried out by elemental anal., FT IR, 1H NMR, UV-Vis. and MS. Optimized mol. structure and harmonic vibrational frequencies have been investigated by DFT/B3LYP and HF methods combined with 6-31G(d) basis set. Stability of the mol. arises from hyperconjugative interactions, charge delocalization and intramol. hydrogen bond has been analyzed using natural bond orbital (NBO) anal. Electronic structures were discussed by TD-DFT method and the descriptions of frontier MOs and the relocation of the electron d. were detd. 1H NMR chem. shifts were computed by Gauge-invariant AO (GIAO) method in both gas and DMSO media, using the polarizable continuum model (PCM). Structure-activity relationship has been used to correlate biol. activity with some appropriate quantum descriptors such as EHOMO, ELUMO, energy gap, dipole moment (µ), global hardness (η), softness (S), electrophilicity index (ω), mol. polarizability (α), Mulliken electronegativity (χ), Mulliken charge (Qi) and mol. electrostatic potential (MEP).

Abstract

This study targets to develop curcumin-loaded polyvinyl alcohol/cellulose nanocrystals (PVA/CNCs) membrane as localized delivery system for breast/liver cancer. A novel strategy was developed for enhancing encapsulation capacity and maximizing therapeutic efficiency of curcumin-loaded PVA/CNCs membranes. Membranes were prepared by solution-casting method using citric acid as crosslinker. SEM revealed that PVA/CNCs ratio (80:20) was chosen as the optimum for loading curcumin. FT-IR indicated that, curcumin was incorporated into PVA/CNCs in amorphous-phase via intermolecular hydrogen bond between curcumin and membrane components. Curcumin showed biphasic-release through burst-release of 41% of curcumin during the first hour, followed by sustained-release of 70% and 94% during 24 h and 48 h, respectively. In vitro cytotoxicity of PVA/CNCs/Curcumin membrane exhibited a selective inhibition proliferation of breast and liver cancer cells in a concentration-dependent without any toxic effect on normal cells. At high concentration (8 mg/ml) of PVA/CNCs/Curcumin, reduced viability to 35% and 7% of MCF-7 and Huh-7 cells, respectively; meanwhile high HFB-4 normal cell viability ≥80% was investigated. Antimicrobial activity of PVA/CNCs/Curcumin was investigated by multi-drug-resistant strains, and MIC values. PVA/CNCs/Curcumin membranes with concentration (40 mg/ml) showed broad-spectrum antimicrobial activities, thus inhibited ~96-99% of microbial growth. PVA/CNCs/Curcumin membranes could be as promised anti-infective biomaterials for breast and liver cancer wound healing.
