摘要:
A method for identifying a compound that inhibits the NAD+-dependent deacetylase activity of a SIR2 protein is disclosed. These compounds are useful for the treatment of cancers and other diseases, through the activation of silenced genes, through the promotion of apoptosis in cancerous cells, and through the inhibition of transcriptional repressor activity in oncogenes.
摘要:
Compounds are described that are useful for treating an apoptosis-associated disease, which are specifically cytotoxic to tumor cells that are overexpressing Bcl-xL, and are much less cytotoxic in isogenic cells that are not overexpressing Bcl-xL. Also described is a method for treating an apoptosis-associated disease in a subject in need thereof, comprising administering to the subject a therapeutically effective amount of an active compound that is specifically cytotoxic to tumor cells that are overexpressing Bcl-xL, and are much less cytotoxic in isogenic cells that are not overexpressing Bcl-xL. Several scaffolds of active compounds are described.
摘要:
Methods for the treatment of a proliferative disorder are provided in which a subject in need of such treatment is administered an effective amount of a compound selected from: compounds of formula (I) or a pharmaceutically acceptable salt thereof, wherein X1 and X2 are independently H, Cl, F, Br, I, CN, CF3 or NO2, and Ar1 is a substituted or unsubstituted aryl or a substituted or unsubstituted heteroaryl; and compounds of formula (II) wherein X3 and X4 are each independently H, Cl, F, Br, I, CN, CF3 or NO2; Y is (C2–C6)alkylene or (C2–C6)heteroalkylene; and Z is Cl, F, Br, I, CN, CF3 or NO2.
摘要:
Disclosed are 2-methoxy antimycin derivatives or analogs that modulate apoptosis by binding to the hydrophobic groove of a Bcl-2 family member protein (e.g., Bcl-2 or BCl-xL). The 2-methoxy antimycin derivatives or analogs are used in disclosed methods for treating apoptosis-associated diseases such as, for example, neoplastic disease (e.g., cancer) or other proliferative diseases associated with the over-expression of a Bcl-2 family member protein.

摘要:
The present invention provides methods of identifying compounds that protect against ototoxicity induced by one or more noxious stimuli, and methods of treating an individual with compounds identified using the present screening methods. Also provided are compounds demonstrated to have otoprotective effects.
