【預期用途】
尼古丁(Nicotine)是煙草中的主要生物堿,是導致吸煙成癮的物質動因,也是評價人體攝入煙草煙霧的常用指標。但因為尼古丁半衰期短,無法作為標志物檢測,其代謝物可替寧因為半衰期長作為吸煙和戒煙的標志物。
本品采用競爭抑制法和膠體金免疫層析技術,用于快速定性檢測人體唾液中的可替寧,適用于評價煙草煙霧攝入的初步篩查。

后者是CB1受體中由疏水氨基酸殘基所形成的一種配體結合口袋。其形狀與配體的互補性越大,則受體與配體的親和力也就越大。 此次,劉志杰課題組“解析”了CB1與拮抗劑AM6538復合物的高分辨率精細結構,*揭示了拮抗劑小分子是如何與受體相互作用的。“它的結合口袋以及相互作用的關鍵氨基酸,對今后設計高特異性的抑制劑類藥物提供了非常重要的結構及理論基礎,也為分析不同類型的分子配體與受體的作用模式提供了更精確的三維結構模型。”劉志杰介紹道。 更重要的是,該研究團隊發現之前發表的關于CB1的三維預測模型大部分都不是很準確,這就導致設計出來的藥物小分子的特異性不高,會同時作用于與CB1同源性較高的其他受體而產生副作用。 “作為治療抑郁癥和戒細菌的潛在靶點,CB1對于抗焦慮的療效也具有潛力。它主要分布于中間神經元,從而發揮行為抑制的優勢。”李揚解釋說,“比如抑郁癥的發生,一方面是情緒中樞功能亢進,另一方面就是高級認知功能低下和行為抑制功能失控。CB1主要作用負面情緒調節,增強判斷力。” 相關藥物研究將有所突破 “因為結構不明,所以一直以來在抗抑郁癥等領域對于CB1的關注不夠。當然,抑郁癥的發病機制比較復雜,治療途徑也包括多種通路。目前來說,上處于臨床一期、二期、三期在研的抗抑郁藥有幾十種,針對人體內二十多種靶點,其中CB1則屬于潛在靶點之一。”李揚表示,“劉志杰教授的貢獻會讓更多的人將注意力轉移到CB1。” 劉志杰表示,這項研究在對藥物依賴治療的研究中就將起到一定作用。“以前的研究報道,內源性細菌系統在尼古丁成癮神經機制中具有重要的作用,CB1的拮抗劑可以減少對尼古丁的渴求行為。我們的晶體結構揭示了拮抗劑小分子與CB1的復雜疏水結合口袋,AM6538非共價的緊密結合模式使其具備了成為長效緩釋藥物分子的巨大潛力,這一特性也是治療成癮障礙藥物的基本要求。”

The latter is a ligand-binding pocket formed by hydrophobic amino acid residues in the CB1 receptor. The greater the complementarity between the shape and the ligand, the greater the affinity of the ligand to the ligand. This time, Liu Zhijie's group "resolved" the high-resolution fine structure of CB1 and the antagonist AM6538 complex, revealing for the first time how antagonistic small molecules interact with the receptor. "Its binding pocket and key amino acids interacting provide a very important structural and theoretical basis for the design of highly specific inhibitor drugs in the future, as well as providing insight into the mode of action of different types of ligands and receptors More accurate three-dimensional structural model. "Liu Zhijie introduction road. More importantly, the team found that most of the previously published three-dimensional predictive models for CB1 were not very accurate, leading to low specificity of the designed drug small molecule and simultaneous effects on CB1 homology High side effects of other receptors. "CB1 also has potential for anxiolytic efficacy as a potential target for the treatment of depression and bacteriocidosis, and it is mainly distributed in the interneurons, thereby exerting the advantage of behavioral inhibition." Li Yang explained that "such as the occurrence of depression , On the one hand is the emotional center hyperthyroidism, on the other hand is the high cognitive dysfunction and behavioral inhibition function out of control .CB1 main negative emotional regulation, enhance the ability to judge. "Relevant drug research will be a breakthrough" because the structure is unknown, so has been Since the depression in areas such as CB1 is not enough attention.Of course, the pathogenesis of depression is more complex, the treatment also includes a variety of pathways.At present, the international phase one, two, three in the research There are dozens of antidepressants targeted at more than 20 kinds of targets in the human body, of which CB1 is one of the potential targets. "Li Yang said," Professor Liu Zhijie's contribution will allow more people to divert attention to CB1 "Liu Zhijie said the study will play a role in the study of drug dependence. Previous studies have reported that endogenous bacterial systems play an important role in the nicotine addiction neural mechanism, and CB1 antagonists can reduce the thirst for nicotine.Our crystal structure reveals a complex hydrophobic interaction between small antagonist molecules and CB1 In combination with the pockets, AM6538's non-covalent, tightly-coupled mode of delivery gives it the potential to become a long-acting, sustained-release drug molecule that is also essential for the treatment of addictive disorders.
