Sažetak
Statement of the Problem: Due to the structural similarity of imidazo-pyridine heterocyclic system with naturally occurring purines and great therapeutic potential and significance, suchlike derivatives nowadays play an important role in medicinal chemistry and drug discovery. Imidazo- pyridine derivatives foregrounded their importance in the prevention of proper functioning of cancerous cells, diseases related to the central nervous system, inflammation, etc. Methodology & Theoretical Orientation: Taking into account a great biological potential and the fact that imidazo[4, 5-b]pyridine scaffold is among the most privileged and important building blocks in medicinal chemistry as well as our previously published significant biological results of imidazo[4, 5-b]pyridine derivatives, we have designed and synthesized novel tetracyclic derivatives as novel and potent antiproliferative agents. Findings: The synthesis of all newly prepared compounds was conducted using conventional methods of organic synthesis and microwave assisted synthesis. Tetracyclic derivatives were substituted with chosen amino side chains which have significantly enhanced the antiproliferative activity of tetracyclic derivatives and are placed at the different position of skeleton. Additionally, the impact of the N atom position in pyridine nuclei on biological activity was studied. Conclusion & Significance: The antiproliferative activity of regioisomers was studied against human cancer cells and non-tumour cells. As a standard drug etoposide was used and interestingly, the majority of compounds showed improvement of antiproliferative activity on HCT116 and MCF-7 cancer cells when compared to etoposide. From the obtained results it could be noticed that the position of N nitrogen in pyridine ring has strong impact on the antiproliferative activity while the type of amino substituent did not influence activity signifcantly. Thus, regioisomers 6, 7 and 9 substituted with amino substistuents at position 2 showed noticeable enhancement of activity in comparison to their counterparts 10, 11 and 13 having IC50 values from 0.3 M to 0.9 M against all three cancer cells.
