有研究結(jié)果顯示,細(xì)菌的主要有效成分——細(xì)菌大細(xì)菌(THC)主要作用于CB1受體。 細(xì)菌素不僅存在于能令人上癮的細(xì)菌中(植物性細(xì)菌素,THC),也自然地存在于動(dòng)物神經(jīng)和免疫系統(tǒng)里(內(nèi)源性細(xì)菌素,N-花生四烯酸氨基乙醇和2-花生四烯酸甘油)。從中世紀(jì)開始,就有醫(yī)生已經(jīng)認(rèn)識(shí)到細(xì)菌具有治療效果。事實(shí)上,現(xiàn)代醫(yī)學(xué)也證明了細(xì)菌素對(duì)于治療多發(fā)性硬化癥和某些類型的疼痛有一定的效果。尚在研究階段的數(shù)據(jù)顯示,細(xì)菌素對(duì)某些癌癥和腦外傷造成的損害可能有一定的療效。而且,CB1特異性小分子拮抗劑在治療肥胖及相關(guān)并發(fā)癥、精神性疾病、肝纖維化和尼古丁成癮等方面顯示了不俗的效果。 2006年,*用于治療肥胖癥的CB1特異性拮抗劑利莫那班獲得歐洲醫(yī)學(xué)委員會(huì)(EMA)的上市批準(zhǔn)。很快,美國FDA卻發(fā)現(xiàn)該藥物可能引發(fā)焦慮、抑郁、細(xì)菌傾向等精神方面的副作用,從而禁止。同時(shí),歐洲也很快發(fā)現(xiàn)這種藥確實(shí)會(huì)引起抑郁、焦慮甚至細(xì)菌傾向,zui終只能將其撤下。 但是,由于缺乏對(duì)減肥藥利莫那班(Rimonabant, Sanofi-Aventis)與CB1相互作用分子層面的了解,至今人們對(duì)減輕CB1藥物副作用的努力收效甚微。“差不多5年前,人們還曾經(jīng)認(rèn)為CB1結(jié)構(gòu)無法破解。”中國科學(xué)院上海藥物研究所研究員李揚(yáng)在接受《中國科學(xué)報(bào)》記者采訪時(shí)提及。 “這是因?yàn)镃B1蛋白的表達(dá)量比較低,穩(wěn)定性差,很難獲得足夠穩(wěn)定的蛋白樣品進(jìn)行晶體學(xué)研究。”上海科技大學(xué)iHuman研究所副所長、教授、該項(xiàng)目負(fù)責(zé)人劉志杰在介紹CB1研究瓶頸時(shí)表示。 揭示CB1三維精細(xì)結(jié)構(gòu) 面對(duì)重重困難,劉志杰課題組的研究人員嘗試了大量不同的表達(dá)載體改造策略,與學(xué)術(shù)機(jī)構(gòu)以及藥企合作,對(duì)不同類型的配體小分子進(jìn)行篩選和針對(duì)結(jié)晶學(xué)實(shí)驗(yàn)設(shè)計(jì)穩(wěn)定性更好、解離速率更慢的小分子。“我們對(duì)不同的表達(dá)系統(tǒng)及不同的細(xì)胞系都進(jìn)行了嘗試,發(fā)現(xiàn)它們對(duì)晶體的生長和衍射質(zhì)量影響很大,這一點(diǎn)在之前的GPCR結(jié)構(gòu)研究中,沒有引起足夠的重視。”該論文的*作者華甜對(duì)《中國科學(xué)報(bào)》記者解釋道。 這項(xiàng)研究成功解析了CB1與小分子拮抗劑AM6538復(fù)合物的三維精細(xì)結(jié)構(gòu),分辨率達(dá)到2.8埃(10-10米)。特別重要的是,該晶體結(jié)構(gòu)揭示了CB1結(jié)合AM6538的復(fù)雜疏水結(jié)合口袋(binding pocket)。

Some studies have shown that the main bacterial component of bacteria - Bacteria (THC) mainly act on the CB1 receptor. Bacteriocins are found not only in addictive bacteria (plant bacteriocins, THC) but also naturally in the animal's nervous and immune system (endogenous bacteriocins, N-arachidonic acid aminoethanol and 2- Arachidonic acid glycerol). From the beginning of the Middle Ages, some doctors have realized that bacteria have a therapeutic effect. In fact, modern medicine has also demonstrated that bacteriocins have some effect on the treatment of multiple sclerosis and certain types of pain. Data still under study shows that bacteriocins may have some effect on some cancers and traumatic injuries. Moreover, CB1-specific small molecule antagonists have shown impressive results in the treatment of obesity and related complications, psychiatric disorders, liver fibrosis and nicotine addiction. In 2006, the first CB1 antagonist, rimonabant, used to treat obesity was marketed approved by the European Medical Commission (EMA). Soon, the United States FDA found that the drug may cause psychological side effects such as anxiety, depression, bacterial propensity, and thus banned. In the meantime, Europe soon discovered that the drug did cause depression, anxiety and even bacterial tendencies, eventually removing it. However, efforts to alleviate the side effects of CB1 have so far failed due to a lack of understanding of molecular aspects of the interaction of the bariatric drug Rimonabant (Sanofi-Aventis) with CB1. "Almost five years ago, people once thought CB1 could not be cracked," said Li Yang, a researcher at Shanghai Institute of Materia Medica, Chinese Academy of Sciences, in an interview with a reporter at China Science News. "This is because CB1 protein expression is low, poor stability, it is difficult to obtain sufficiently stable protein samples for crystallography." Shanghai University of Technology iHuman Institute Deputy Director, Professor Liu Zhijie, the project leader in introducing the CB1 study When the bottleneck said. To reveal the three-dimensional fine structure of CB1 faces many difficulties, Liu Zhijie's group of researchers tried a large number of different transformation strategies of expression vectors, with international academic institutions and pharmaceutical companies to screen different types of ligand small molecules and for crystallization experiments Design better stability, slower dissociation rate of small molecules. "We tried out different expression systems and different cell lines and found that they have a great influence on the crystal growth and diffraction quality, which did not get enough attention in previous GPCR structure studies." The first author, Hua Tian, ??explained to reporters in China Science News. This study successfully resolved the three-dimensional fine structure of CB1 with the small molecule antagonist AM6538 complex with a resolution of 2.8 angstroms (10-10 m). Of particular importance, this crystal structure reveals the complex hydrophobic binding pocket of CB1 binding AM6538.
