quinazolinone derivatives are essential units in a wide range of relevant pharmacophores with a broad spectrum of abilities. due to their wide range of pharmacological and therapeutic activities including anticonvulsant, anti-inflammatory, hypolipidemic, anticancer, and anti-ulcer, the synthesis of quinazolinone moieties as a privileged class of fused heterocyclic compounds, have received much ...

BACKGROUND AND OBJECTIVES Multiple chromosome rearrangements (MCRs) are found in 5-10% of newly diagnosed patients with acute myeloid leukemia (AML) and 15-30% of patients with myelodysplastic syndromes (MDS). However, the initial causes of MCRs and the molecular mechanisms involved are largely unresolved. Nor are the karyotypic patterns well studied, mainly because of the difficulties of obtai...

This paper investigates prices of consumer electronics sold on the Web by both onlineonly retailers (Dotcoms) and the online branches of multi-channel retailers (MCRs). Surprisingly, we find that Dotcoms charge higher price than MCRs, a conclusion contradictory to the results of most of empirical studies. We also find that the electronics prices decreased over the period of study in general, dr...

The rapid development of science and technology has brought urgent demand for diversity in polymer structures functionalities, the pursuit new polymerizations is constant goal chemistry. Multicomponent reactions (MCRs)—reactions three or more starting materials able to generate a single product one-pot manner—feature series advantages such as simple reactants, easy operation, mild conditions, h...
