Nitrogen mustards (NM) with 2-chloroethylamino fragment are used as antineoplastic agents in therapy of cancer as nonspecific DNA alkylating agents. The antitumor activity of nitrogen mustards has been connected with their ability to cross-link the twin strands of DNA which if not repaired, can inhibit DNA replication and transcription, eventually leading to cell cycle arrest, apoptosis, and the inhibition of tumor growth. Classical NM drugs don’t operate selectivity, causing high levels of inadvertent DNA damage in normal cells, toxic and mutagenic side effects, and in some cases, leading to secondary malignancies Therefore, the search for the new analogues is continued expecting improvement of therapeutic index by modification of NM structure. In our previous report [1] we presented results of synthesis of triazines substituted with one, two or three 2-chloroethylamine moiety 1-3 and studies on the determination of apoptotic index and cell vialibility on the standard cell line of mammalian tumor MCF-7 by the compounds obtained.

The studies shown that triazine derivatives 1-3 inhibits 50% of colony formation at the concentration in the range 13,88 µM to 146,79 µM, while the IC50 of chlorambucil is 24,6 µM. Herein, we present the studies on alkylation of broad range of nucleophiles with triazine NM 1-3.
