DESCRIPTION:

BRIEF SUMMARY
FIELD OF THE INVENTION

The present invention relates to a new method of treatment using compounds which are dual non-selective .beta.-adrenoceptor and .alpha..sub.1 -adrenoceptor antagonists, in particular the carbazolyl-(4)-oxypropanolamine compounds of Formula I, preferably carvedilol, for inhibiting the expression of Fas, a cell surface protein.


BACKGROUND OF THE INVENTION

Cell proliferation, differentiation, and survival are often regulated by growth, differentiation, and survival factors, respectively, which are collectively called cytokines. Cytokines bind to their complementary receptors, which transduce the extracellular signal into an intracellular signaling cascade. Fas ligand (FasL) is a cytokine. It is one of the few known cytokines that is a death factor. This ligand binds to its receptor, Fas, a cell-surface protein, and induces apoptosis (cell death). Many tissues and cell lines weakly express Fas, but abundant expression has been found in mouse heart, liver, lung, kidney, ovary and thymus (R. Watanabe-Fukunaga, et al., J. Immunol., 148, 1274-1279 (1992)). In the immune system, Fas and FasL are involved in down-regulation of immune reactions as well as in T cell-mediated cytotoxicity. Malfunction of the Fas system causes lymphoproliferative disorders and accelerates autoimmune diseases, whereas its exacerbation may cause tissue destruction (S. Nagata, et al., Science, 267, 1449-1456 (1995)).
Surprisingly, it has been found that carvedilol, a dual non-selective .beta.-adrenoceptor and .alpha..sub.1 -adrenoceptor antagonist, inhibits the expression of Fas. This inhibition may mean that carvedilol and related Formula I compounds are useful for diseases wherein inhibition of Fas-mediated apoptosis is indicated. Particularly, this inhibition may mean that carvedilol and related Formula I compounds are useful for blocking ischemia-induced apoptosis in cardiac cells, for preventing or inhibiting tissue remodeling, in particular in cardiac tissue and blood vessels, for treating autoimmune diseases, and for inhibiting tumor growth and metastasis.


SUMMARY OF THE INVENTION

The present invention relates to a new method of treatment using compounds which are dual non-selective .beta.-adrenoceptor and .alpha..sub.1 -adrenoceptor antagonists, in particular the carbazoiyl-(4)-oxypropanolamine compounds of Formula I, preferably carvedilol, for inhibiting the expression of Fas. The invention also relates to a method of treatment using compounds which are dual non-selective .beta.-adrenoceptor and .alpha..sub.1 -adrenoceptor antagonists, in particular the carbazolyl-(4)-oxypropanolamine compounds of Formula I, preferably carvedilol, for inhibiting apoptosis. Furthermore, this invention relates to a method of treatment using compounds which are dual non-selective .beta.-adrenoceptor and .alpha..sub.1 -adrenoceptor antagonists, in particular the carbazolyl-(4)-oxypropanolamine compounds of Formula I, preferably carvedilol, for diseases wherein inhibition of Fas-mediated apoptosis is indicated. In particular, this invention is directed to the use of Formula I compounds, preferably carvedilol, to specifically induce Fas-mediated apoptosis of undesirable cells, such as cancer or autoreactive immune cells. Additionally, when control of aberrant forms of Fas activation is desired, the Formula I compounds, preferably carvedilol, are used to prevent cell depletion in AIDS or neurodegenerative diseases.
This invention also relates to a method of treatment using compounds which are dual non-selective .beta.-adrenoceptor and .alpha..sub.1 -adrenoceptor antagonists, in particular the carbazolyl-(4)-oxypropanolamine compounds of Formula I, preferably carvedilol, for preventing or inhibiting tissue remodeling, in particular in cardiac tissue and blood vessels. The present method includes the use of compounds which are dual non-selective .beta.-adrenoceptor and .alpha..sub.1 -adrenoceptor antagonists, in particular the carbazolyl-(4)-oxypropanolarnine compounds of Formula I, preferably carvedilol, to block ischemia-ind
