Farnesyltransferase Inhibitors for Treatment of Laminopathies, Cellular Aging and Atherosclerosis

Hutchinson-Gilford Progeria Syndrome (HGPS) is a very rare progressive childhood disorder characterized by premature aging (progeria). Recently, the gene responsible for HGPS was identified (Eriksson M, et al. Nature 2003), and HGPS joined a group of syndromes — the laminopathies — all of which are caused by various mutations in the lamin A/C gene (LMNA). Lamin A is one of the family of proteins that is modified post-translationally by the addition of a farnesyl group. In progeria, the abnormal protein (progerin) can still be farnesylated, however, a subsequent cleavage is blocked.

The present invention describes a possible treatment of laminopathies, cellular aging and aging-related conditions such as HGPS through the use of farnesyltransferase inhibitors (FTIs) and other related compounds. This treatment should lead to a decrease in the accumulation of abnormal proteins such as progerin in case of HGPS patients and therefore reduce or eliminate many of the devastating clinical symptoms of the underlying biological defect of nuclear membrane instability (Goldman R, et al. PNAS 2004).
