Continuing our research in the field of new heterocyclic compounds, herein we report on the synthesis and antitumor activity of new amino derivatives of pyrido[3’,2’:4,5](furo)thieno[3,2-d]pyrimidines as well as of two new heterocyclic systems: furo[2–e]imidazo[1,2-c]pyrimidine and furo[2,3-e]pyrimido[1,2-c]pyrimidine. Thus, by refluxing the 8-chloro derivatives of pyrido[3’,2’:4,5]thieno(furo)[3,2-d]pyrimidines with various amines, the relevant pyrido[3’,2’:4,5]thieno(furo)[3,2-d]pyrimidin-8-amines were obtained. Further, the cyclization of some amines under the action of phosphorus oxychloride led to the formation of new heterorings: imidazo[1,2-c]pyrimidine and pyrimido[1,2-c]pyrimidine. The possible antitumor activity of the newly synthesized compounds was evaluated in vitro. The biological tests evidenced that some of them showed pronounced antitumor activity. A study of the structure–activity relationships revealed that the compound activity depended mostly on the nature of the amine fragments. A docking analysis was also performed for the most active compounds.

Background. The addition of active metabolites (in particular, amino acids) to the molecule affects the physicochemical and prodrug properties of derivatives of indolocarbazoles. Using computed chemoinformatics, probability antitumor activity of amino-acid derivatives of glycosides of indolocarbazol (AADGI) is predicted with low probability of their cytotoxic activity in vitro. Based on these data, a study of these compounds in vivo is conducted. Objective: the assessment of AADGI as potential antitumor medications. Materials and methods. Research antitumor activity of AADGI was done using murine tumor models - cervical cancer CC-5. Investigated compounds were injected to mice СВА abdominally 5-times daily with interval of 24 h. Observation of animals were continued till their death. Antitumor effect of compounds was assessed by criteria of tumor growth inhibition and increase in life expectancy of mice comparing to control animals. Results. The optimal dose for these series of compounds was titrated and this dose is 100 mg/kg. Antitumor activity of AADGI was assessed on CC-5. Conclusions. Based on data received we suggest an extended study in vivo of antitumor qualities of selected 5 leader AADGI.

The synthesis of a variety of nucleoside analogs involving modifications in the carbohydrate ring is described. In particular, 6-substituted purin-9-yl derivatives of 1-oxa-4-thiacyclohexane and 1,4-dioxacyclohexane have been synthesized. A number of 6-chloropurin-9-yl derivatives of substituted 1-oxa-4-thiacyclohexane have also been derived from the parent compounds by way of a Pummerer rearrangement. A route to nucleoside analogs of 1-oxa-4-thiacyclohexane from naturally occurring nucleosides is illustrated for the case of inosine. A route to nucleoside analogs in which the carbohydrate moiety is replaced by an acyclic moiety bearing α,β-unsaturated esters is also illustrated for the case of uridine. The results of biological screening of these analogs and others previously synthesized in our program against leukemia L-1210 cells in vitro are presented; some of these compounds showed marginal antitumor activity. The screening results of selected compounds against the human HeLa cell line in vitro are also presented; none of the compounds that were tested showed significant inhibitory activity of cell growth.
