Pharmacotherapy of prostate cancer is an important part in combating oncologic diseases. This is very relevant, because prostate cancer is a cause of 10 % of deaths from all cancerous diseases in males. The aim of the study – to synthesize novel derivatives of 1-(41-isopropylphenyl)-4-(42-chlorophenyl)5,6,7,8-tetrahydro-2,4а-diazacyclopenta[cd]azulene-2-carboxylic acid arylamides and to evaluate their antitumor activity against PC-3 prostate cancer cells. By reaction of equimolar amounts of 2-methoxy-3,4,5,6-tetrahydro-7H-azepine with a-amino-4-chloroacetophenone chlorohydrate, 3-(4-chlorophenyl)-6,7,8,9- tetrahydro-5Н-imidazo[1,2-a]azepine was synthesized. By alkylation of a-bromo-4-іsopropylacetophenone in ethylacetate and following treatment of the obtained intermediary quaternary salt with excess of 5 % NaOH solution,1-(41-isopropylphenyl)-4-(42chlorophenyl)-5,6,7,8-tetrahydro-2,4а-diazacyclopenta[cd] azulene was synthesized. By boiling it with equimolar amounts of correspondding arylisocyanates in dried benzol, an array of 1-(41-iso propylphenyl)-4(42-chlorophenyl)-5,6,7,8-tetrahydro-2,4а-diazacyclopenta[cd]azulene-2-carboxylic acid arylamides were synthesized. Structure and purity of all compounds obtained were confirmed by data of MR1Н spectroscopy. Lipophilicity (LogP) of compounds 6 and 8 a-i was calculated with the ACD LogP program. Antitumor activity of 1-(41-isopropylphenyl)-4-(42-chlorophenyl)-5,6,7,8-tetrahydro-2,4а-diazacyclopenta[cd]azulene-2-carboxylic acid (3-methylphenyl) and (3-methoxyphenyl)-amides was evaluated at in vitro test on prostate cancer PC-3 cell lines. It is indicated, that at concentration of 10–5 M these compounds exceed 5-fluorouracil as comparison drug in inhibiting PC-3 prostate cancer cells growth by 52.32 % and 3.93 % correspondingly. The data obtained substantiate feasibility of further studies of 1-(41-isopro pylphenyl)-4-(42-chlorophenyl)-5,6,7,8-tetrahydro-2,4а-diazacyclopenta[cd] azulene-2-carboxylic acid arylamides as new, potential antitumor medicines for prostate cancer treatment.
