The pseudoglycosyltransferase (PsGT) VldE is a glycosyltransferase-like protein that is similar to trehalose 6-phosphate synthase (OtsA). However, in contrast to OtsA, which catalyzes condensation between UDP-glucose and glucose 6-phosphate, VldE...
The title compound, C18H20N4O2S2, is a new 1,3,4-oxa­diazole and a key pharmacophore of several biologically active agents. It is composed of a meth­yl(thio­phen-2-yl)-1,3,4-oxa­diazole-2(3H)-thione moiety linked to a 2-meth­oxy­phenyl unit via a...

Background The persistent appearance of viral strains that causes a resistant viral infection has led to continuous trials for the design and development of novel antiviral compounds. Benzoquinazoline compounds have been reported to exhibit an...
The main objective was to determine the elemental profile of the lung lining fluid of rats which are used as model animals in various experiments. Lung lining fluid elemental constitution obtained after bronchoalveolar lavage fluid (BALF) was...
Background: The antimicrobial activity of a synthesized series of 28 2-thioxobenzo[ g]quinazolin-4(3H)-one derivatives was evaluated in vitro against five Gram-positive bacteria, including Bacillus subtilis, Enterococcus faecalis, Staphylococcus...
In this study, a new series of quinazoline derivatives (3–26) was synthesized and characterized via physicochemical and spectral means. Treatment of 2-amino-5-methylbenzoic acid with butyl isothiocyanate resulted in the new 2-thioxoquinazolin-4-one...
A new series of quinazoline-4(3H)-ones are evaluated for anticonvulsant activity. After intraperitoneal (ip) injection to albino mice at a dose of 100 mg/kg body weight, synthesized quinazolin-4(3H)-ones (1–24) were examined in the maximal...
Low-quality medicines deliver sub-optimal clinical outcomes and waste precious health resources. It is important to ensure that public funds are spent on healthcare technologies that meet national regulatory bodies such as the Saudi Food and Drug...
Aim: 16 thioxoquinazolines were evaluated in vivo for anti-inflammatory activity using carrageenan-induced paw edema assay. Results: In particular, out of the targets (1–16), compounds 4 and 6 displayed the highest anti-inflammatory activity (≥80%)...
Aim: The present study was carried out to assess a new series of triazoloquinazolines 1–40 for their antioxidant activities using 1,1-diphenyl-2-picryl hydrazyl radical scavenging, ferric reduction antioxidant power and reducing power capability...
The main objective of this work was to synthesize novel compounds with a benzo[de][1,2,4]triazolo[5,1-a]isoquinoline scaffold by employing (dioxo-benzo[de]isoquinolin-2-yl) thiourea as a building block. Molecular docking was conducted in the COX-2...
A new series of 4,6-disubstituted 2-(4-(dimethylamino)styryl)quinoline 4a,b–9a,b was synthesized by the reaction of 2-(4-(dimethylamino)styryl)-6-substituted quinoline-4-carboxylic acids 3a,b with thiosemicarbazide, p-hydroxybenzaldehyde,...
