摘要:
[Problem] Provided is a non-peptide compound which can be used as a GAPDH aggregation inhibitor. [Solution] Provided is a GAPDH aggregation inhibitor including as an active ingredient a compound represented by the chemical formula 1 wherein R1, R2, and R3 are each independently a hydrogen atom, a halogen atom, or an aliphatic hydrocarbon group having a carbon number of from 1 to 10, a polysulfurized derivative thereof, or a pharmaceutically acceptable salt thereof. The present compound has a GAPDH aggregation inhibitory activity to suppress intracerebral aggregation of various proteins involved in cerebral neurodegenerative diseases, thereby contributing to improvement in various brain neurological diseases associated with aggregation of these proteins such as Alzheimer's disease, Parkinson's disease, and cerebral infarction, and prevention of advanced seriousness of these diseases.

摘要:
The present invention comprises analogs of the CAAX motif of the protein Ras that is modified by farnesylation in vivo. These CAAX analogs inhibit the farnesylation of Ras. Furthermore, these CAAX analogues differ from those previously described as inhibitors of Ras farnesyl transferase in that they do not have a thiol moiety. The lack of the thiol offers unique advantages in terms of improved pharmacokinetic behavior in animals, prevention of thiol-dependent chemical reactions, such as rapid autoxidation and disulfide formation with endogenous thiols, and reduced systemic toxicity. Further contained in this invention are chemotherapeutic compositions containing these farnesyl transferase inhibitors and methods for their production.
