- a pharmaceutical product comprising a compound of formula I, a compound having vitamin A activity and a pharmaceutically acceptable carrier, diluent or excipient therefor.
- a preferred compound with vitamin A activity is all-trans retinoic acid (ATRA).
- the individual proliferation-inhibiting effects of the compounds can be increased by combining a compound of the formula I with a compound having vitamin A activity.
- the pharmaceutical product according to the invention enables increased proliferation-inhibiting effects to be achieved without it being necessary to increase the dose of the compound of the formula I to a level where toxicity-related side effects are no longer tolerable.
- ceramide has been shown to be a potential intracellular mediator of various substances that can control cell growth differentiation and survival. It is produced by hydrolysis of sphingomyelin. The main activities include induction of cell differentiation, inhibition of the cell cycle and apoptosis.
- a pharmaceutical product comprising a compound of formula I or a compound of formula II (dFdU), ceramide and a pharmaceutically acceptable carrier, diluent or excipient therefor.
- the individual anti-proliferative effects of the compounds can be increased.
- the pharmaceutical product according to the invention thus enables increased proliferation-inhibiting effects to be achieved without it being necessary to raise the dose of compound of the formula I or dFdU to a level where toxicity-related side effects are no longer tolerable.
- a pharmaceutical product which comprises a compound of the formula I or a compound of the formula II (dFdU), a compound belonging to the class of interleukins and a pharmaceutically acceptable carrier, diluent or excipient therefor. It is preferred that the compound belonging to the class of interleukins is interleukin- ⁇ .
- the individual anti-proliferative effects of the compounds can be increased.
- the pharmaceutical product according to the invention enables increased proliferation-inhibiting effects to be achieved without it being necessary to increase the dose of compound of the formula I or dFdU to a level where toxicity-related side effects are no longer tolerable.

As can be seen from FIG. 2, a dose-dependent proliferation-inhibiting effect of ATRA, which reached its maximum at 1000 nM / ml, was found.
- Example 3 Effect of ceramide on the proliferation-inhibiting activity of dFdU and dFdC
- the cells (1 ⁇ 10 5 / ml) were changed with varying doses of ceramide (N-acetyl-D-sphingosine, A-7191, Sigma) incubated in the range of 0.1 to 20 ⁇ M / ml for 7 days.
- ceramide N-acetyl-D-sphingosine, A-7191, Sigma
- the results were determined using an MTT assay and are shown in FIG. 5.
- a dose-dependent growth-inhibiting effect was found at a ceramide concentration in the range from 0.1 to 20 ⁇ M.
