Abstract Present manuscript describes the synthesis and molecular structure features of novel condensed pyrido[1,2-a]quinazolines. The above-mentioned compounds were synthesized via condensation of 2-[azolyl-(аzinyl-)]anilines with 5-oxohexanoic acid. The tandem condensation intermediates were isolated and cyclized under various conditions. The structures of synthesized compounds were confirmed by

Reactions of 3-(2-aminophenyl)-6-R-1,2,4-triazin-5(2H)-ones with aryl isocyanates and aryl isothiocyanates were studied by using solvents of various nature, as well as varying the temperature regime and process duration. The series of synthesized compounds was shown to exhibit pronounced cytostatic activity with respect to specific cell lines of melanoma, non-small cell lung cancer, kidney cancer,

Previously unknown 3′-R1-spiro[(aza/oxa/thia)cycloalkyl-1(3, 4),6′-[1,2,4]triazino[2,3-c]quinazolin]-2′(7′H)-ones were obtained on the basis of (5+1) cyclocondensation reaction of substituted 6-R1-3-(2-aminophenyl)-1,2,4-triazin-5(2Н)-ones with cyclic ketones. It was established that the steric and electronic factors of cyclic ketones did not affect the reaction duration and product yields. The structure
