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

Reference of 29976-53-2, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 29976-53-2, Name is N-Carbethoxy-4-piperidone, molecular formula is C8H13NO3. In a Article，once mentioned of 29976-53-2

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.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Reference of 29976-53-2, you can also check out more blogs about29976-53-2

Reference of 1484-84-0, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.1484-84-0, Name is 2-Piperidineethanol, molecular formula is C7H15NO. In a Article，once mentioned of 1484-84-0

Aqueous piperazine (PZ) blended with a tertiary or hindered amine combines the high CO2capacity of the tertiary or hindered amine with the fast rate of PZ. For flue gas CO2capture, the optimum pKa(that which offers the highest CO2cyclic capacity) of a mono-tertiary amine blended with PZ is 9.1. A generic Aspen Plus model for PZ/tertiary amine was developed to predict the CO2vapor-liquid-equilibrium (VLE) from the pKaof the tertiary amine. The polarity of the tertiary amine also affects the CO2solubility of the PZ/tertiary amine. Hindered amines that form little carbamate show similar CO2VLE to tertiary amines with the same pKa, when blended with PZ. The CO2absorption rate of most 2.5 m PZ/2.5 m tertiary amines was slightly slower than 2.5 m PZ, probably due to the higher viscosity of the blends.

A new series of monocyclic pseudopeptide tachykinin NK-2 receptor antagonists has been derived from the lead compound MEN11558. A synthesis for these molecules sharing the same intermediate was designed and performed. The replacement of the succinic moiety with an aspartic acid and the functionalization of its amino group with a wide variety of substituents led to very potent and selective NK-2 antagonists. Best results were obtained through the insertion in position 12 of an amino group with R configuration, linked by a short spacer to a saturated nitrogen heterocycle (morpholine, piperidine, or piperazine). The study led to compounds 54 and 57, endowed with high in vivo potency at very low doses and long duration of action in animal models of bronchoconstriction. In particular 54 and 57 completely inhibited NK-2 agonist induced bronchoconstriction in guinea pig after intratracheal administration at subnanomolar doses (ED50 = 0.27 nmol/kg and 0.15 nmol/kg, respectively).
