-Lyophilized Fruit Extract Attenuated Acute Redox-Homeostatic Imbalance via Mutagenic and Oxidative Stress Modulation in Mice Model on Gentamicin-Induced Nephrotoxicity.

Gentamicin (GM) administration is associated with decreased metabolism, increased oxidative stress, and induction of nephrotoxicity. L., containing flavonoids, anthocyanins, and phytosterols, possesses antioxidant and anti-inflammatory potential.

Self-Assembled Molecular Complexes of 1,10-Phenanthroline and 2-Aminobenzimidazoles: Synthesis, Structure Investigations, and Cytotoxic Properties.

Three new molecular complexes (phen)(2-amino-Bz)(H)(BF)·3HO , (phen)(2-amino-5(6)-methyl-Bz)(H)(BF)·HO , and (phen)(1-methyl-2-amino-Bz)(H)(BF) , were prepared by self-assembly of 1,10-phenanthroline (phen) and various substituted 2-aminobenzimidazoles. Confirmation of their structures was established through spectroscopic methods and elemental analysis. The X-ray diffraction analysis revealed that the crystal structure of is stabilized by the formation of hydrogen bonds and short contacts.

Neuroprotection in non-transgenic and transgenic mouse models of Alzheimer's disease by positive modulation of σ receptors.

The sigma-1 (σ) receptor is an endoplasmic reticulum (ER) chaperone protein, enriched in mitochondria-associated membranes. Its activation triggers physiological responses to ER stress and modulate Ca mobilization in mitochondria. Small σ agonist molecules activate the protein and act behaviorally as antidepressant, anti-amnesic and neuroprotective agents.

Self-assembly of novel molecular complexes of 1,10-phenanthroline and 5-amino-1,10-phenanthroline and evaluation of their in vitro antitumour activity.

Novel molecular complexes of 1,10-phenanthroline (phen) and 5-amino-1,10-phenanthroline (5-NH2-phen) [(5-NH2-phen)2(phen) (H2O)3 (1), (phen)2(imidazole) (H+) (BF4-) (2), (phen)2(benzimidazole) (H+) (BF4-) (3), (5-NH2-phen)4(H2O)3 (4), and (phen)3 (indole) (H+) (BF4-) (5)] were synthesized via self-assembly processes and their in vitro anticancer activity was investigated. The structures of the compounds were confirmed by UV, FTIR, CIMS(CH4) and elemental analysis. The crystal structure of 2 was determined by X-ray diffraction.

Drug discovery: phosphinolactone, in vivo bioisostere of the lactol group.

In drug discovery, structural modifications over the lead molecule are often crucial for the development of a drug. Herein, we reported the first in vivo bioisosteric effect of phosphinolactone function in relation to the lactol group constituting the bioactive molecule: Hydroxybupropion. The preparation of phosphinolactone analogues and their antidepressant evaluation towards forced swimming test in mice showed that biological activity was regained and even strengthen.

Cytotoxicity and effects of 1,10-phenanthroline and 5-amino-1,10-phenanthroline derivatives on some immunocompetent cells.

The biological activity of previously synthesized compounds [(phen)(3)(H(+))(2)(NO(3)(-))(2) (1), Pd(5-NH(2)-phen)(2)(NO(3))(2) (2) and Pd(phen)(2)(NO(3))(2)(H(2)O) (3)] was investigated in vivo. The three compounds did not show any histological alterations in the observed lung, liver, spleen and lymph nodes of White Wistar rats. The propidium iodine staining did not discover any cytotoxic effect of the tested derivatives.

Antitumour activity of novel 1,10-phenanthroline and 5-amino-1,10-phenanthroline derivatives.

Synthesis and impact on the tumour growth of palladium(II) complex of 5-amino-1,10-phenanthroline Pd(5-NH(2)-phen)(2)(NO(3))(2) and the protonated dimer (phen)(2)(H(+))(BF(4)(-)) have been described. In the reported experiments a cancerous (100% lethality) myeloid subcutaneous tumour (with Graffi-tumour origin) in hamsters was used. The animals were injected i.
