Niche for acridine derivatives in anticancer therapy.

During the last 4 decades, intensive research has focussed on the effect of small organic molecules with antitumour activity that are able to intercalate into DNA and inhibit topoisomerase and telomerase enzymes. In this review, we describe some of the chemical and biological properties of acridine, which is a chemotherapeutic agent that has been used for cancer treatment since 1970. In addition, we summarise the progress that has been made in the development of anticancer agents based on the clinical in vivo/in vitro studies that have been conducted for 13 classes of natural and synthetic acridines.

Substituted thiazolidinediones and thio-imidazolidinones: synthesis, structural study and pharmacological activity.

Synthesis and physico-chemical properties of six 3-(4-bromophenacyl)-5-arylidene-thiazolidine-2,4-diones and eight 3-(4-chlorobenzyl)-5-arylidene-4-thio-imidazolidine-2-ones are described. These products were synthesized by an aldolisation-crotonisation reaction from aromatic aldehydes and 3-substituted thiazolidine-2,4-diones or 4-thio-imidazolidine-2-ones. Hypoglycemic and peripheral antinociceptive activities were investigated for these compounds.
