- Novel potential pyrazolopyrimidine based translocator protein ligands for the evaluation of neuroinflammation with PET
-
Translocator protein (TSPO) is an interesting biological target because TSPO overexpression is associated with microglial activation caused by neuronal damage or neuroinflammation, and these activated microglia are involved in several central nervous syst

- Synthesis and evaluation of novel potent TSPO PET ligands with 2-phenylpyrazolo[1,5-a]pyrimidin-3-yl acetamide
-
Translocator protein (TSPO) expression is closely related with neuroinflammation and neuronal damage which might cause several central nervous system diseases. Herein, a series of TSPO ligands (11a–c and 13a–d) with a 2-phenylpyrazolo[1,5-a]pyrimidin-3-yl acetamide structure were prepared and evaluated via an in vitro binding assay. Most of the novel ligands exhibited a nano-molar affinity for TSPO, which was better than that of DPA-714. Particularly, 11a exhibited a subnano-molar TSPO binding affinity with suitable lipophilicity for in vivo brain studies. After radiolabeling with fluorine-18, [18F]11a was used for a dynamic positron emission tomography (PET) study in a rat LPS-induced neuroinflammation model; the inflammatory lesion was clearly visualized with a superior target-to-background ratio compared to [18F]DPA-714. An immunohistochemical examination of the dissected brains confirmed that the uptake location of [18F]11a in the PET study was consistent with a positively activated microglia region. This study proved that [18F]11a could be employed as a potential PET tracer for detecting neuroinflammation and could give possibility for diagnosis of other diseases, such as cancers related with TSPO expression.

- 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.

- Synthesis and antirhinovirus activity of 6-(dimethylamino)-2-(trifluoromethyl)-9-(substituted benzyl)-9H-purines
-
A series of 6-(dimethylamino)-2-(trifluoromethyl)-9-(substituted benzyl)purines was synthesized and tested for antirhinovirus activity. Most of the compounds were synthesized by alkylation of 6-chloro-2-(trifluoromethyl)-9H-purine with the appropriate benzyl halide followed by displacement of the chloro group with dimethylamine. Alternatively, 6-(dimethylamino)-2-(trifluoromethyl)purine was alkylated with the appropriate benzyl halide. Although several different aryl substituents provided compounds with IC50's = 0.03 μM against rhinovirus serotype 1B, no congener was significantly more active than the parent 2. Twenty-three compounds were tested against 18 other serotypes, but none exhibited a uniform profile of activity.
