FIELD: organic chemistry.
SUBSTANCE: invention relates to the compounds containing five-membered rings with three nitrogen atoms as a heteroatom, namely 3-(4-(3-oxo-3-(2-((Z)-5-oxo- 5-(((S)-1,2,3,10-tetramethoxy-9-oxo-5,6,7,9-tetrahydrobenzo[a]heptalen-7-yl)amino)pentan-2-ylidene)hydrazienyl) propyl)-1H-1,2,3-triazol-1-yl)propan-1,2-diyl dipalmitate formula
, where
X= 
. The invention can be used as a prodrug form of an antitumor drug for the treatment of cancer.
EFFECT: reduction of nonspecific toxic effects from the use of the active substance and enhance of its accumulation in the tumor due to the effect of increased permeability and retention characteristic of the vessels of solid tumors.
