Using Selenium-enriched Mutated Probiotics as Enhancer for Fertility Parameters in Mice.

Increasing fertility rates have become one of the factors that concern all people in the world. Therefore, the study aims to use two mutated strains of probiotics enriched with selenium (PSe40/60/1 and BSe50/20/1) to improve fertility. Thirty Swiss albino male mice were divided into three groups; control, LP + S was given Lactobacillus plantarum PSe40/60/1 plus selenium, and BL + S was given Bifidobacterium longum BSe50/20/1 plus selenium.

Synthesis, Characterization, and Anti-diabetic Activity of Some Novel Vanadium-Folate-Amino Acid Materials.

A new six intraperitoneal injections insulin-mimetic vanadyl(IV) compounds [(VO)(FA)(AA)] (where n = 1-6: AA = isoleucine, AA = threonine, AA = proline, AA = phenylalanine, AA = lysine, and AA = glutamine) were synthesized by the chemical reactions between folic acid (FA), VOSO, and amino acids (AA) with equal molar ratio 1:1:1 in neutralized media. These complexes were characterized by elemental analysis and estimation of vanadyl(IV) metal ions. The thermal stability behavior of these complexes was studied by TG-DTG-DTA analyses.

Synthesis, characterization and antidiabetic effects of vanadyl(II) adenosine monophosphate amino acid mixed-ligand complexes.

This research paper is aimed at designing a novel insulin alternative for the treatment of diabetes. Six novel vanadyl(II) compounds, [(AMP)(VO)(AA )]·NH , were synthesized from an equimolar ratio of adenosine monophosphate, VOSO and amino acids (AA ). The magnetic moments and electronic spectra revealed the square pyramidal geometrical structure of the complexes.

Synthesis, antibacterial properties and 2D-QSAR studies of quinolone-triazole conjugates.

A set of 1,2,3-triazole incorporated quinolone antibiotic conjugates 10-15, 17-19 were synthesized via microwave assisted click chemistry technique. Some of the aryl-substituted conjugates 17-19 show promising antibacterial properties against the tested Gram-positive (S. aureus and S.

New Inducible Nitric Oxide Synthase and Cyclooxygenase-2 Inhibitors, Nalidixic Acid Linked to Isatin Schiff Bases via Certain l-Amino Acid Bridges.

A series of new Schiff bases were synthesized by condensation of isatins with the nalidixic acid-l-amino acid hydrazides. Prior to hydrazide formation, a peptide linkage has been prepared via coupling of nalidixic acid with appropriate l-amino acid methyl esters to yield 3a-c. The chemical structures of the new Schiff bases (5b and 5d-h) were confirmed by means of IR, NMR, mass spectroscopic, and elemental analyses.

Synthesis of novel vasodilatory active nicotinate esters with amino acid function.

A variety of N-[(ethyl-4,6-diaryl-3-pyridinecarboxylate)-2-yl]amino acid esters 6a-h were synthesized through the reaction of 2-bromonicotinates 4 with a number of primary amino acid ester hydrochlorides 5 in refluxing tetrahydrofuran in the presence of triethylamine as dehydrohalogenating agent. Similarly, reaction of 4 with N-glycylglycine ethyl ester hydrochloride 7 'as a representative example of dipeptide derivative' afforded smoothly the corresponding N-[(ethyl-4,6-diaryl-3-pyridinecarboxylate)-2-yl]-N'-glycylglycine ethyl ester analogues 8. However, reaction of 4 with 5 in refluxing pyridine yielded the unexpected 2-aminonicotinate esters 9.
