Abstract
Dihydroazolopyrimidines are an important class of heterocycles that are isosteric to natural purines and are therefore of great interest primarily as drug-like molecules. In contrast to the heteroaromatic analogs, synthetic approaches to these compounds were developed much later, and their chemical properties and biological activity have not been studied in detail until recently. In the review, different ways to build dihydroazolopyrimidine systems from different building blocks are described - via the initial formation of a partially hydrogenated pyrimidine ring or an azole ring, as well as a one-pot assembly of azole and azine fragments. Special attention is given to modern approaches: multicomponent reactions, green chemistry, and the use of non-classical activation methods. Information on the chemical properties of dihydroazolopyrimidines and the prospects for their use in the design of drugs of various profiles are also summarized in this review.

Abstract
OBJECTIVE Novel bis(1,4-dihydropyridine-3,5-dicarbonitrile) derivatives linked to aliphatic or aromatic cores via amide or ester-amide linkages were prepared and their structures were confirmed by several spectral tools. METHODS The synthesis of novel N,N'-(alkanediyl)bis(2-(2-(3,5-dicyano-2,6-dimethyl-1,4-dihydropyridin- 4-yl)phenoxy)acetamide) by acid-catalyzed condensation of the bis-aldehydes with four equivalents of 3-aminocrotononitrile was reported. RESULTS The structures of the synthesized compounds were confirmed by different spectral tools. The molecular docking stimulation studies indicated that the prepared compounds bind to the active site of cellular inhibitor apoptotic protein (cIAP1-BIR3). MTT assay for the novel bis(1,4-dihydropyridines) was performed on two different human cell lines (A549 and HCT116). CONCLUSION Compound 5a showed higher cytotoxic activity against A549. Compound 5d showed moderate activity against HCT116. The rest of compounds indicated lower or no activity against both cell lines.
