- KP 1019 indazolium frans- [tetrachlorobis (1H-indazole) ruthenate (III)]
- KP 1019 sodium chloride
- composition obtained according to Example 1 were carried out.
- the composition was obtained by reacting the sodium salt KP 1339, which is more than thirty times more soluble in water than KP 1019, with indazolium hydrochloride in the infusion solution immediately before administration.
- KP 1339 has a significantly weaker antiproliferative activity in vitro than KP 1019, further experiments were carried out to determine to what extent the stronger activity of KP 1019 can be restored by adding indazole to solutions of KP 1339.
- the tumor-inhibiting activity of the equimolar mixture of KP 1339 and indazole was found to be identical to that of the original KP 1019 (see Figures 1 and 2), while pure KP 1339 was three to four times less effective than KP 1019. This was demonstrated on two tumor cell lines ( SW480, CH1) confirmed and reproduced four times. The lower effectiveness of KP 1339 compared to KP 1019 was confirmed in these experiments.
- the tumor-inhibiting activity can be increased further by adding an excess of indazole.
- a mixture of KP 1339 and indazole in a molar ratio of 1: 5 resulted in a two to five-fold increase in cytotoxicity compared to KP 1019 (see FIGS. 3 and 4).
- a molar ratio of 1: 2 is already sufficient to exceed the effectiveness of the original KP 1019.
- Indazole itself only exerts a cytotoxic effect in a much higher concentration (> 1 mM).
