  Discovery of SARxxxx92, a pan-PIM kinase inhibitor, efficacious in a KG1 tumor model

  摘要：

  N-substituted azaindoles were discovered as potent pan-PIM inhibitors. Lead optimization, guided by structure and focused on physico-chemical properties allowed us to solve inherent hERG and permeability liabilities, and provided compound 27, which subsequently impacted KG-1 tumor growth in a mouse model.

• Radiolabelling of 1,4-disubstituted 3-[18F]fluoropiperidines and its application to new radiotracers for NR2B NMDA receptor visualization

  In order to develop a novel and useful building block for the development of radiotracers for positron emission tomography (PET), we studied the radiolabelling of 1,4-disubstituted 3-[18F]fluoropiperidines. Indeed, 3-fluoropiperidine became a useful building block in medicinal chemistry for the pharmacomodulation of piperidine-containing compounds. The radiofluorination was studied on substituted piperidines with electron-donating and electron-withdrawing N-substituents. In the instance of electron-donating N-substituents such as benzyl or butyl, configuration retention and satisfactory fluoride-18 incorporation yields up to 80% were observed. In the case of electron-withdrawing N-substituents leading to carbamate or amide functions, the incorporation yields depend on the 4-susbtitutent (2 to 63%). The radiolabelling of this building block was applied to the automated radiosynthesis of NR2B NMDA receptor antagonists and effected by a commercially available radiochemistry module. The in vivo evaluation of three radiotracers demonstrated minimal brain uptakes incompatible with the imaging of NR2B NMDA receptors in the living brain. Nevertheless, moderate radiometabolism was observed and, in particular, no radiodefluorination was observed which demonstrates the stability of the 3-position of the fluorine-18 atom. In conclusion, the 1,4-disubstituted 3-[18F]fluoropiperidine moiety could be of value in the development of other radiotracers for PET even if the evaluation of the NR2B NMDA receptor antagonists failed to demonstrate satisfactory properties for PET imaging of this receptor.

  为了开发用于正电子发射断层扫描（PET）示踪剂的新颖且有用的构建模块，我们研究了1,4-二取代的3-[18F]氟哌啶的放射性标记。实际上，3-氟哌啶已成为药物化学中含哌啶化合物的药效调控的有用构建模块。我们在具有供电子和吸电子N-取代基的取代哌啶上研究了放射性氟化。对于具有供电子N-取代基（如苄基或丁基）的情况，观察到了构型保持和令人满意的氟-18掺入产率，高达80％。在导致形成氨基甲酸酯或酰胺功能的吸电子N-取代基的情况下，掺入产率取决于4-取代基（2至63％）。该构建模块的放射性标记被应用于NR2B NMDA受体拮抗剂的自动放射合成，并通过商用的放射化学模块实现。对三种放射性示踪剂的体内评估显示，其脑摄取量极低，与在活脑中成像NR2B NMDA受体不兼容。然而，观察到了中等程度的放射性代谢，特别是未观察到放射性去氟化，这表明氟-18原子的3位点的稳定性。总之，1,4-二取代的3-[18F]氟哌啶部分可能对开发其他PET示踪剂有价值，即使NR2B NMDA受体拮抗剂的评估未能显示出适用于该受体PET成像的令人满意的特性。

  The invention relates to a method for preparing linear polymers having an amide end or having a star architecture comprising an amide core, by means of a ring opening using lactide and glycolide monomers or a lactide monomer ring in the presence of a catalyst, wherein the method includes the steps of: (i) reacting the excess monomer(s) with an initiator in a solvent, said initiator being selected from among an amine and an amino alcohol, given that the initiator has at least one primary or secondary amine function; (ii) adding a catalyst, said catalyst being a non-nucleophilic base and including at least one neutral sp2 nitrogen atom; and (iii) neutralizing the reaction mixture. Said novel method is particularly advantageous in that it can be easily monitored and enables better modulation of the polymers, and thus of the properties thereof, than the methods of the prior art. The invention also relates to novel polymers that are obtainable by means of said method.
