cytotoxicity

Benzoquinone and its reduced form hydroquinone belong to phenolic compounds and are found in living organisms in free form or in glycosides. They are active substances of some medicinal plants and have a pharmacological effect on the human body. Accordingly, their derivatives are important objects for chemical synthesis and development of new drugs. This article presents the findings of the structural design of substances with benzoquinone or hydroquinone fragment and sulfur-containing compound.

Quinoid derivatives are attractive not only as interesting synthons for synthesis, but also as potential biologically active substances, so it is important to modify the compounds of the quinone series with different pharmacoform fragments.

Pyrimidine and its derivatives are important objects for chemical synthesis and development of new drugs based on them. There is a practical application of a number of substances with a pyrimidine heterocycle in medical practice. We performed a predicted screening of biological activity, cytotoxicity and toxicity in rats of some synthesized pyrimidine thiosulfonates using appropriate on-line programs.

Quinoline and its derivatives are important compounds for the chemical synthesis and development of novel drugs. Practical application of a number of substances with quinoline heterocycle is already known in medical practice.
