- PYRAZOLE DERIVATIVE, OR PHARMACEUTICALLY ACCEPTABLE SALT THEREOF
-
[Problem] The present invention is to provide a novel pyrazole derivative, or a pharmaceutically acceptable salt thereof, a pharmaceutical composition comprising the same, and a pharmaceutical use thereof. [Solution] The present invention provides a compound represented by the formula (I) or a pharmaceutically acceptable salt thereof, which has TRPM8 inhibitory effects: wherein ring A is C6-10 aryl or the like; X is CR4a or the like; R1 and R2 are a hydrogen atom or the like; R3 is a hydrogen atom or the like; R4 is a hydrogen atom or the like; ring B is C6-10 aryl or the like; R5 is a hydrogen atom or the like; R6a is a hydrogen atom or the like; R7a is a hydrogen atom or the like; R7b is a hydrogen atom or the like; R6b is a hydrogen atom or the like; R8 is a hydrogen atom or the like; n is 0, 1 or 2. Therefore, the compound represented by the formula (I) of the present invention or a pharmaceutically acceptable salt thereof is useful as an agent for treating or preventing diseases or symptoms caused by hyperexcitability or disorder of afferent neurons.

- Discovery and development of an efficient, scalable, and robust route to the novel CENP-E inhibitor GSK923295A
-
The discovery and development of an efficient manufacturing route to the CENP-E inhibitor 3-chloro-N-{(1S)-2-[(N,N-dimethylglycyl)amino]-1-[(4-{8-[(1S)- 1-hydroxyethyl]imidazo[1,2-a]pyridin-2-yl}phenyl)methyl]ethyl} -4-[(1-methylethyl)oxy]benzamide (GSK923295A) is described. The existing route to GSK923295A was expensive, nonrobust, used nonideal reagents, and consistently struggled to deliver the API needed for clinical studies. The new synthesis commences from the readily available l-phenylalaninol, which is smoothly converted through to GSK923295A using key Friedel-Crafts acylation as well as selective acylation chemistries. Downstream chemistry to GSK923295A is both high yielding and robust, and the resulting process has been demonstrated first on the kilo scale and subsequently in the pilot plant where 55 kg was successfully prepared. The resulting process is simple, uses cheaper raw materials, is greener in that it avoids using aluminum, tin, and bromination chemistries, and obviates the need for chromatographic purification. Also discussed are the route derived impurities, how they were unambiguously prepared to confirm structure and processing amendments to control their formation, and enhancements to the new process to facilitate future processing.
