The present invention relates to analogs of cortistatin A, J, K, and L, having the general formula: I and salts thereof, wherein R 1 , R 2 , R 3 , R 4 , n, and m are as defined herein; processes for preparing such compounds and intermediates thereto; pharmaceutical compositions comprising such compounds; methods for treating a proliferative disease; methods for treating a disease associated with aberrant angiogenesis; methods for inhibiting angiogenesis; and processes for preparing cortistatin A, J, K, and L, and analogs thereof.
摘要:
The present invention provides a novel 11-step enantioselective approach to the natural product hyperforin, which enables access to a wide variety of hyperforin analogs. The present invention also provides pharmaceutical compositions comprising inventive hyperforin analogs. Hyperforin analogs synthesized using the present synthetic method are envisionsed useful in the treatment of various conditions, including, but not limited to, depression and conditions characterized by depression, inflammatory skin conditions, diabetes, asthma, chronic obstructive pulmonary disease (COPD), kidney disorders, and ischemic brain damage.
摘要:
The invention relates in part to the discovery that certain CRAMs, such as schweinfurthin A, target OSBPs (a family of oxysterol binding proteins). Because OSBPs have been shown to be integral to atherosclerosis and Alzheimer's disease (AD), one aspect of the invention relates to the use of CRAMs, or a pharmaceutically acceptable salt, biologically active metabolite, solvate, hydrate, prodrug, enantiomer or stereoisomer thereof, in the treatment and/or prevention of atherosclerosis, Alzheimer's disease and related disorders. Another aspect of the invention relates to novel derivatives of CRAMs, or a pharmaceutically acceptable salt, biologically active metabolite, solvate, hydrate, prodrug, enantiomer or stereoisomer thereof, for the treatment and/or prevention of atherosclerosis, Alzheimer's disease and related disorders. Another aspect of the invention relates to the use of an immobilized CRAMs, such as OSW-I, to aid in screening of compounds to identify additional OSBP binders. Other aspects of the invention relate to the use of CRAMs to treat cancer, such as p21-deficient cancers.
