This article describe the applicability of 1,4-disulfopiperazine-1,4-diium chloride ([Piper-(SO3H)2].2Cl) as a green, versatile and Brönsted acidic ionic catalyst in the promotion of the synthesis of phthalazine derivatives via one-pot three component reaction between aromatic aldehydes, 1,3-diketone derivatives and phthalhydrazide under solvent-free reaction cond...

A series of novel 1, 8-dioxo-octahydroxanthene derivatives containing 4-thiazolidinone framework (4a-f) were synthesized through a four-step reaction starting from the reduction of nitro derivatives of 1, 8-dioxo-octahydroxanthenes. The resulting aminoxanthenes converted to thiourea derivatives via their reaction with methyl isothiocyanate. The final products were synthesized through the re...

Antimalarial drugs with the 4-aminoquinoline scaffold such as the important drugs, chloroquine (CQ) and amodiaquine (AQ), have been used to prevent and treat malaria for many years. The importance of these drugs is related to their simple usage, high efficacy, affordability, and cost-effectiveness of their synthesis. In recent years, with the spread of parasite resistance to CQ and cross-resist...

Novel liquid crystal (LC) dendrimers have been synthesised by hydrogen bonding between an s-triazine as the central core and three peripheral dendrons derived from bis(hydroxymethyl)propionic acid. Symmetric acid dendrons bearing achiral promesogenic units have been synthesised to obtain 3:1 complexes with triazine that exhibit LC properties. Asymmetric dendrons that combine the achiral promeso...

Benzodiazepines are an important class of heterocyclic compounds in organic chemistry. They known for their diverse physicochemical and biological properties. Some benzodiazepine derivates well-known drugs with strong pharmacophoric moiety. An immense number pharmacological research on heterocycles derivatives have recently been conducted to explore its numerous potentials as better therapeutic...

cancer is a major global problem and is the second leading cause of mortality in the developed countries.resistance to current chemotherapeutics and high incidence of adverse effects are the two principal reasons for developing new anticancer agents. phenylacetamide derivatives can act as potential anticancer agents. synthesis and screening of 2-(4-fluorophenyl)-n-phenylacetamide derivatives in...
