a method for producing them, pharmaceutical compositions containing them, and the use thereof for regularing mGluR5 receptors, or for treating or inhibiting disorders or disease states at least partially mediated by mGluR5 receptor such as pain, anxiety attacks, drug or alcohol dependency, and others.
A straightforward synthesis of pyrimido[4,5-d]pyridazines from pyrimidines and tetrazines under basic conditions is reported. Deprotonated, substituted 5-halopyrimidines readily react with variously substituted tetrazines in a highly regioselective manner via a complex reaction pathway, which was supported by DFT calculations. This mechanism leads to the empirically observed regioisomers without going
报道了在碱性条件下由嘧啶和四嗪直接合成嘧啶并[4,5- d ]哒嗪的方法。去质子化的取代的5-卤代嘧啶易于通过复杂的反应途径以高度区域选择性的方式与各种取代的四嗪发生反应,这得到了DFT计算的支持。该机理导致通过经验观察到的区域异构体而不经过可能的戊炔中间体。关于5-卤代嘧啶的这些结果导致开发了基于6-卤代嘧啶的相反的区域异构体的制备方法。

Disclosed is a liposome, comprising a lipid bilayer enclosing a cavity, wherein the bilayer comprises a channel protein releasably linked to an eight-membered non-aromatic cyclic alkenylene group, preferably a cyclooctene group, and more preferably a trans-cyclooctene group. The liposomes are used in a kit comprising the liposome, the liposomal membrane of which comprises a channel protein linked to a Trigger, and an Activator for the Trigger, wherein the Trigger comprises the eight- membered non-aromatic cyclic alkenylene group, and the Activator comprises a diene.
