A series of 2-(5-(6-Bromo-2-methyl-4-oxoquinazolin-3(4H)-yl)-4H-1,2,4-triazole-3-ylthio)-N-(substituted benzylidene) acetohydrazides (5a-5l) have been synthesized via condensation of 2-(5-(6-Bromo-2-methyl-4-oxaquinazolin-3 (4H)-yl)-4H-1,2,4-triazole-3-ylthio)acetohydrazide (4) with different aromatic aldehydes. Cycloaddition of thioglycolic acid with 5a-5l yielded 2-[5-(6-Bromo-2-methyl-4-oxoq...

The addition of 7-chloro-4-nitrobenzofurazan (NBD) to isolated CF1 at pH 7.5 leads to one tyrosine-bound NBD molecule per CF1 in one of the three beta-subunits, concomitantly with the inhibition of the ATPase activity. Addition of ADP prior to NBD-incubation protected the ATPase activity and reduced binding of NBD to beta-subunits. The addition of MgATP prior to modification did not result in p...

In the title thio-ether dihydrate, C(18)H(10)Cl(2)N(2)S·2H(2)O, the S-bound quinolinyl residues are almost orthogonal, forming a dihedral angle of 72.36 (4)°. In the crystal, the four water mol-ecules are connected via an eight-membered {⋯OH}(4) synthon with each of the four pendent water H atoms hydrogen bonded to a pyridine N atom to stabilize a three-dimensional architecture.

Two new sensors for the detection of reactive oxygen species have been synthesized and characterized; they contain the 4-amino-7-nitrobenzofurazan (ABF) moiety covalently tethered to a phenol. Comparison of sensors ABFhd and dABFhd (the latter containing two ortho-methyl groups) shows that introduction of steric bulk leads to an improvement of fluorescent sensor performance, thus confirming our...

Abstract Green analytical chemistry is one of the newest trends in nowadays targeting concept green laboratory practices on chemists and environment. In this text, are proposed work for determination sofosbuvir (SF) velpatasvir (VP) their pharmaceutical formulation. The analysis SF a binary mixture with VP represents an challenge due to complete overlapping UV spectrum by that VP. Therefore, di...

BACKGROUND A recent study showed that methylphenidate induces emergence from isoflurane anesthesia. Methylphenidate inhibits dopamine and norepinephrine reuptake transporters. The objective of this study was to test the hypothesis that selective dopamine receptor activation induces emergence from isoflurane anesthesia. METHODS In adult rats, we tested the effects of chloro-APB (D1 agonist) an...
