Synthetic Route of 236406-39-6, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.236406-39-6, Name is 8-Boc-2,8-Diazaspiro[4.5]decane, molecular formula is C13H24N2O2. In a article，once mentioned of 236406-39-6

4-Fluoro-N-{2-[4-(6-trifluoromethylpyridin-2-yl)piperazin-1-yl]ethyl} benzamide is a full 5-HT1A agonist with high affinity (pK i=9.3), selectivity and a clog P of 3.045. The corresponding PET radioligand 4-[18F]fluoro-N-{2-[4-(6-trifluoromethylpyridin-2-yl) piperazin-1-yl]ethyl}benzamide was synthesized by nucleophilic aromatic substitution on the nitro precursor. The fluorinating agent K[ 18F]F/Kryptofix 2.2.2 was both dried (9 min, 700 W) and incorporated in the precursor (5 min, 700 W) using a commercially available microwave oven. In a total synthesis time of 60 min, an overall radiochemical yield of 18% (SD=5, n=7, EOS) was obtained. Radiochemical purity was always higher than 99% and specific activity always higher than 81.4 GBq/mumol (2.2 Ci/mumol). Initial brain uptake in mice was 2.19% ID (5.47% ID/g, 2 min) but decreased rapidly (0.17% ID, 0.45% ID/g (60 min)). During the first 20 min p.i., radioactivity concentration of the brain was significantly higher than that of blood demonstrating good brain entry of the tracer. Copyright

Analysis of the structural requirements of compound 1 (SR48968), a potent NK2 receptor antagonist, revealed that the 4-phenyl group of the piperidine is essential for binding with the NK2 receptor and occupies an equatorial position. Energy calculation of a variety of substituted 4-phenyl piperidines revealed that spiro[isobenzofuran-1(3H), 4′-piperidine] possesses a conformationally restricted equatorial phenyl group. Our compound 12 (YM- 35375) possessing this spiro-substituted piperidine bound to the NK2 receptor with an IC50 value of 84nM and to the NK1 receptor with an IC50 value of 710nM. It showed more potent inhibitory activity (ID50 41mug/kg (i.v.)) against [beta-Ala8]-NKA(4-10)-induced bronchoconstriction in guinea pigs than (±)-SR48968 (ID50 68mug/kg (i.v.)). YM-35375 may be a new lead compound for novel NK2 receptor antagonists or NK1-NK2 dual antagonists.
