Discovery of a Selective TRPM8 Antagonist with Clinical Efficacy in Cold-Related Pain
摘要:
The transient receptor potential (TRP) family of ion channels comprises nonselective cation channels that respond to a wide range of chemical and thermal stimuli. TRPM8, a member of the melastatin subfamily, is activated by cold temperatures (<28 degrees C), and antagonists of this channel have the potential to treat cold induced allodynia and hyperalgesia. However, TRPM8 has also been implicated in mammalian thermoregulation and antagonists have the potential to induce hypothermia in patients. We report herein the identification and optimization of a series of TRPM8 antagonists that ultimately led to the discovery of PF-05105679. The clinical finding with this compound will be discussed, including both efficacy and its ability to affect thermoregulation processes in humans.
Substituted benzamide compounds are provided along with methods for the use of those compounds for treating cancer.

[Problems] To provide an efficient process for producing an optically active chromene oxide compound which is an important intermediate for a benzopyran compound effective in the treatment of arrhythmia.
[Means For Solving Problems] The process for producing an optically active chromene oxide compound comprises using an optically active titanium complex represented by, e.g., the formula (1) or (2)
as a catalyst to asymmetrically oxidize an optically active chromene compound with high enantioselectivity in high chemical yield.
