Efficacy of N-sulfoniypyrimidine derivatives and hyperthermia on the mouse tumour growth
Background: New compounds have been firstly tasted on different mouse tumour models and evaluated as potential anticancer drugs. Among many anticancer compounds, heterocyclic organic compounds have been recently more tested by us in order to find antitumour activity. Pyrimidine is one of heterocyclins, which showed interesting cytotoxic effect. Newly synthesizes N-sulfonyl derivatives of pyrimidine have shown potential anticancer activity in our study. Therefore, in this study we wanted to investigate antitumour activity of newly N-sulfonyl derivatives of pyrimidine nucleobases and local hyperthermia on the growth of anaplastic mammary carcinoma. Material and methods: In this study we used a transplantable mouse mammary carcinoma (TMMCa). Tumour cells (106) were injected into the footpad of the right hind leg (intrasolearly) of CBA mice. Tumour bearing mice have been treated with N-sulfonylpyrimidine derivatives or with 5-fluorouracil (positive control) with and without hyperthermia (43, 0oC/60 min). The end point was tumour growth time (TGT). N-sulfonylpyrimidine derivatives have been synthesized in Rudjer Boskovic Institute. Antitumor activity was examined for: 1-(p-toluenesulfonyl)cytosine (4H) and 1-(p-toluenesulfonyl)cytosine hydrochloride (4HxHCl). Results: The presented results show that both examined N-sulfonylpyrimidine derivatives (4H and 4HxHCl) had strong antitumour activity. Local hyperthermia alone had statistically significant antitumour activity. But hyperthermia in combination with these derivatives enhanced the antitumour activity of 1-(p-toluenesulfonyl)cytosine hydrochloride (4HxHCl). All new compounds showed similar or slightly better antitumour effects comparing to 5-fluorouracil.
