布格呋喃是中國醫(yī)學科學院藥物研究所和北京協(xié)和制藥二廠合作研制開發(fā)的1.1類化學新藥，擬用于治療廣泛性焦慮癥（generalized anxiety disorder）。
Buagafuran is a kind of Class 1.1 new chemical drug, developed under the cooperation of Pharmaceutical Research Institute of Chinese Academy of Medical Sciences and No.2 Pharmaceutical Plant of Beijing Union Medical College, intended to treat the generalized anxiety disorder.
 
布格呋喃是名貴中藥沉香提取物沉香呋喃的衍生物�！侗静菥V目》記載：沉香有清人神，益氣合神等作用。70年代初，中國醫(yī)學科學院藥物研究所即已觀察到沉香精油具有一定的鎮(zhèn)靜催眠作用，因此對沉香呋喃天然化合物進行了立體選擇性合成和結構改造，合成了一系列新的衍生物，經過藥效學和毒理學篩選，發(fā)現(xiàn)布格呋喃具有顯著的抗焦慮活性，毒副作用較低，無依賴性和耐受性。
Buagafuran is the derivative of Agarofuran (an extract of aloe wood, a precious traditional Chinese medicine). In “Compendium of Materia Medica”, it records that agilawood can restore consciousness, be benefit to Qi, etc. In early 1970s, Pharmaceutical Research Institute of Chinese Academy of Medical Sciences has already found that the essential oil of agilawood had a certain sedative and hypnotic effect, so the natural compounds of Agarofuran have been stereo-selectively synthesized and structurally transformed to form a series of new derivatives, after the screening of drug efficiency and toxicology, it found that buagafuran had significant anxiolytic activity, with lower side effects, without dependence and tolerance.
 
藥效試驗顯示，布格呋喃具有穩(wěn)定的抗焦慮作用。其抗焦慮強度接近安定。在12種焦慮模型中, 布格呋喃均有量-效相關的抗焦慮作用，其抗焦慮譜與安定相同而明顯寬于丁螺環(huán)酮。且重復給藥時，布格呋喃的抗焦慮作用不發(fā)生耐受性（且有逐漸增強的趨勢），也沒有停藥反應。在單獨給藥時，布格呋喃只有鎮(zhèn)靜效應，無論多大劑量和給藥途徑，都沒有催眠作用。布格呋喃也無肌松與肌協(xié)調損傷作用；對學習、記憶損傷不明顯；無木僵效應；對痛疼無抑制作用。
The pharmacodynamic trial showed that the buagafuran had stable anxiolytic effect. Its anxiolytic strength was close to Diazepam. In the twelve kinds of anxiety model, the buagafuran had the anxiolytic effect related with dosage-efficiency, and its anti-anxiety spectrum was same as that of Diazepam, and wider that than that of Buspirone. If repeatedly administrated, the anxiolytic effect of buagafuran didn’t have tolerance (in gradually increasing trend) or withdrawal reaction. If independently administrated, the buagafuran only had sedative effect, no matter how much dosage and what the route of administration, there was no hypnotic effects. Buagafuran also cannot relax muscle or damage the muscle coordination; the damage to learning and memory was not obvious; no stupor effect; no inhibition to pain.
 
在急毒試驗中，布格呋喃5 g/kg 不會引起動物死亡，也無共濟失調或其它感覺-運動的明顯毒性效應。因此，布格呋喃中樞神經系統(tǒng)毒性、副作用低于丁螺環(huán)酮。安全性藥理研究結果顯示布格呋喃治療劑量范圍內對犬心電圖、血壓、心率、及呼吸無異常影響。Beagle犬口服給予布格呋喃9個月的無明顯毒副反應劑量為5 mg/kg，15mg/kg和50mg/kg劑量組除血清ALP水平升高外，體重、進食量、心電圖、神經活動狀況、尿生化、血液學、以及其它血清生化指標等均未見明顯變化。布格呋喃對動物生殖力對仔代無明顯影響，亦無遺傳毒性。依賴性實驗顯示實驗動物對布格呋喃不產生生理依賴性和精神依賴性。
In acute toxicity test, 5g/kg buagafuran cannot cause death of animal, nor ataxia or other obvious toxic effects of sensory-motor. Therefore, the central nervous system toxicity and side effects of buagafuran are lower than these of buspirone. The results of safety pharmacology study showed that it could not affect the ECG, blood pressure, heart rate, and respiratory of dog in the therapeutic dosage range of buagafuran. After Beagle dogs were oral administrated buagafuran for 9 months, the dosage without significant toxic side effects was 5 mg/kg, while in the dosage group of15mg/kg and 50mg/kg there was no significant changes in body weight, food intake, ECG, status of neural activities, urine biochemistry, hematology, and other serum biochemical parameters except the serum ALP level was increased. Buagafuran has no significant impact on the reproductive capacity and offspring of animal, and it also has no genotoxicity. In the dependence experiment, it showed that the experimental animals didn’t generate physical dependence or psychological dependence to buagafuran.
 
大鼠和犬藥代動力學研究顯示布格呋喃吸收較快，口服后5~10min血漿中既可檢測到原形藥物，10-40min血藥濃度達峰，各組織均有分布，經過尿、糞排泄出體外，大鼠和人血漿蛋白結合率為97%。
In the pharmacokinetic studies of rat and dog, it showed that buagafuran was absorbed quickly, after oral administration for 5 ~ 10min the unchanged drug could be detected in plasma, and 10-40min later the plasma concentration would be up to peak, distributed in every tissue, excreted outside via urine and feces, the binding rate of rat and human plasma protein was 97%.
 
布格呋喃現(xiàn)已完成Ⅰ期臨床研究，包括單次給藥和多次給藥的健康人體耐受性試驗、單次給藥和多次給藥的健康人體藥代動力學研究以及食物對藥代動力學影響的研究。人體耐受性研究證實本品在15~90mg劑量范圍內單次和多次給藥的人體耐受性良好。
Buagafuran has completed Phase I clinical studies, including the tolerance test of single-dose and multiple dose administration to healthy human, the pharmacokinetic study of single-dose and multiple dose administration to healthy human, and the study about the influence of food on pharmacokinetics. The human tolerance study confirmed that the human tolerance was good in single-dose and multiple dose administration in the dosage range of 15 to 90mg of this product.
 
人體藥代動力學實驗結果顯示：中國健康受試者單次、多次空腹及進食后口服30~120mg布格呋喃安全性和耐受性良好。中國健康男性受試者單次口服布格呋喃膠囊30mg，60mg或120mg后，吸收較為迅速，總體暴露量和最高瞬時暴露水平都隨著劑量的增加而升高，但與劑量并不成比例關系，藥物消除隨劑量增加而減慢。進食對單次口服60mg布格呋喃膠囊的系統(tǒng)暴露水平有影響：達峰時間延長，血漿峰濃度下降，曲線下面積增加。單次和每日兩次連續(xù)口服布格呋喃膠囊60mg或120mg后，布格呋喃被快速吸收，并在每日兩次重復口服后不久達穩(wěn)態(tài)。與單劑的藥代動力學參數(shù)相比，重復給藥后的暴露量有中度蓄積。120mg組的布格呋喃清除率低于60mg組。
The human pharmacokinetics experimental results showed: Chinese healthy subjects orally administrated 30 to 120mg buagafuran in single and multiple times after fasting or eating, the security and tolerance were good. After the Chinese healthy male subjects single orally administrated 30mg, 60mg or 120mg buagafuran capsules, the absorption was relative fast, and the overall exposure and maximum instantaneous exposure levels were increased with the increase of dosage, but not proportional to dosage, and the drug elimination was slowed down with the increase of dosage. Eating would affect the system exposure level of 60mg buagafuran capsule in single oral administration: time to reach peak was prolonged, the peak plasma concentration was decreased, and the area under the curve was increased. After oral administration of 60mg or 120mg buagafuran capsules in single time and two consecutive times a day, buagafuran was rapidly absorbed; after two repeated oral administration a day it would be in steady state shortly. Compared with the pharmacokinetic parameters of single dose, the exposure had moderate accumulation after repeated dosage. In 120mg group, the elimination rate of buagafuran was less than that of 60 mg group.

抗腫瘤及抗腫瘤轉移雙功能藥物候選物MTC-220（臨床前研究）
 MTC-220, candidate for drugs with anti-tumor and anti-metastatic dual functions (pre-clinical study)
 
腫瘤轉移是腫瘤患者的主要臨床致死原因，占腫瘤死亡人數(shù)的83%。最新研究表明，腫瘤的炎癥微環(huán)境與惡性腫瘤的侵襲與轉移直接相關，改變這種微環(huán)境可以阻止腫瘤轉移。本課題是將免疫調節(jié)劑胞壁酰二肽（MDP）衍生物與紫杉醇以適當形式共綴，在保持紫杉醇抗腫瘤活性的同時，還可通過調節(jié)腫瘤微環(huán)境而產生抗腫瘤轉移作用。
The tumor metastasis is the main clinical cause of death in patients with cancer, accounting for 83% of cancer deaths. The latest research showed that the inflammatory microenvironment of tumor was directly related with the invasion and metastasis of malignant tumors, to change such microenvironment might prevent tumor metastasis. In this topic, it is to conjugate the derivatives of muramyl dipeptide (MDP) (an immunomodulating agent) and paclitaxel in an appropriate form; it cannot only keep the antitumor activity of paclitaxel but also generate the anti-metastatic effect by regulating tumor microenvironment.
 
系統(tǒng)研究顯示，紫杉醇與MDP簡化物的共綴物MTC-220是一個新穎、有效、安全的雙功能抗腫瘤候選藥物，不僅在動物體內高效抗腫瘤，而且通過減少髓樣抑制細胞（MDSCs）以及調節(jié)腫瘤微環(huán)境的細胞因子水平（TNF-a等）顯著地抑制惡性腫瘤的轉移。MTC-220在體外可對60株人癌細胞具有與紫杉醇相類似的抗腫瘤譜；在裸鼠體內可顯著抑制多種原發(fā)瘤的生長；在BALB/c小鼠和C57Bl/6小鼠可分別顯著抑制高轉移性乳腺癌和肺癌的轉移；小鼠尾靜脈注射MTC-220最大耐受劑量（138.2mg/kg）遠大于紫杉醇靜脈給藥的半數(shù)致死量（25mg/kg）。MTC-220理化性質得以改善，其制劑可避免使用致敏性的環(huán)氧乙烯蓖麻油，為實現(xiàn)低劑量多次靜脈注射給藥以提高抗腫瘤及抗腫瘤轉移效果提供了基本依據(jù)。所有實驗結果均顯示：MTC-220極有望開發(fā)為新穎的抗腫瘤及抗腫瘤轉移的雙功能藥物。
The systematic research showed that the conjugates MTC-220 of paclitaxel and simplified matter of MDP was a novel, effective and safe dual-function anti-tumor drug candidate, it’s not only able to efficiently prevent tumor in vivo, but also significantly suppress the metastasis of malignant tumors via reducing suppressor cells (MDSCs) and adjusting the levels of cytokines (TNF-a, etc.) of the tumor microenvironment. The anti-tumor spectrum of MTC-220 to 60 strains of human cancer cells in vitro was similar with that of paclitaxel; it could significantly inhibit the growth of primary tumor in nude mice; for BALB/c mice and C57Bl/6 mice, it could respectively significantly inhibit the metastasis of highly metastatic breast cancer and lung cancer; the max tolerated dosage (138.2mg/kg) of MTC-220 in intravenous injection for mice was much more than the median lethal dose (25mg/kg) of paclitaxel in intravenous administration. The physical and chemical properties of MTC-220 were improved, the preparations were avoided the use of allergenic ethylene castor oil, providing the fundamental basis for improving the anti-tumor and anti-metastatic effects via low-dosage multiple intravenous administrations. All experimental results showed that: MTC-220 was highly expected to be developed as a novel anti-tumor and anti-metastatic dual-function drug.

S1P₁受體激動劑（臨床前研究）
S1P1 Receptor Agonist (Preclinical study)
 
S1P₁受體（Sphingosine-1-Phosphate Receptor，5個亞型S1P1~5）激動劑是新型免疫抑制劑，通過誘導外周循環(huán)系統(tǒng)中的淋巴細胞回到淋巴結，即“歸巢”，降低外周循環(huán)中的淋巴細胞數(shù)量而達到治療自身免疫性疾病的目的。該類藥物既不影響粒細胞和單核細胞活性，也不損害淋巴細胞和造血系統(tǒng)，并且淋巴細胞對外界抗原的記憶仍然保存，與傳統(tǒng)免疫抑制藥物相比，對自身免疫系統(tǒng)毒性較小。該類藥物的代表是Fingolimod（FTY720），由諾華制藥公司開發(fā)，已于2010年9月上市，用于多發(fā)硬化癥治療。但是臨床應用中發(fā)現(xiàn)，F(xiàn)TY720有致患者心動過緩的不良反應，與其同時激動S1P₃受體有關。因此，開發(fā)選擇性更高的S1P₁受體激動劑成為開發(fā)治療自身免疫性疾病藥物的方向。
S1P1 receptor (Sphingosine-1-Phosphate Receptor, five subtypes: S1P1-5) agonist is a kind of novel immunosuppressant, through the induction of lymphocytes returning from the peripheral circulatory system to the lymph nodes (i.e., “homing”), to reduce the quantity of lymphocytes in peripheral circulation, it can achieve the purpose of treating autoimmune diseases. Such drugs will not affect neither the activity of granulocyte and monocyte or damage the lymphocytes and hematopoietic system, and the antigens of lymphocyte to the external memory will be still stored, compared with conventional immune suppressing drugs, it has less toxicity to the autoimmune system. The representative of these drugs is Fingolimod (FTY720), developed by Novartis Pharma, was marketed in September 2010, for the treatment of multiple sclerosis. In the clinical applications, it found that FTY720 might induce adverse reactions of bradycardia in patients, which was related with exciting S1P3 receptor. Therefore, the development of more selective S1P1 receptor agonist may be the direction for the development of drugs for treating autoimmune diseases.
 
中國醫(yī)學科學院藥物研究開展了系統(tǒng)的S1P₁選擇性激動劑研究，對200余個新化合物的體內外活性評價發(fā)現(xiàn)多個化合物具有選擇性S1P₁受體激動作用，降低外周血淋巴細胞的活性與FTY720相當或略強，但無心動過緩副作用。與目前國際上正在進行臨床或臨床前研究的新型S1P₁受體激動劑作用強度相當。已申請國內、國際化合物專利保護。
The Pharmaceutical Research Institute of Chinese Academy of Medical Sciences carried out the systematic researches in S1P1 selective agonist, found that many compounds had the effects of selective S1P1 receptor agonist in the activity evaluation of 200 new compounds in vitro and in vivo, the efficiency to reduce the activity of peripheral blood lymphocyte was equal to or better than that of FTY720, without side effect of bradycardia. The strength was equal to that of new S1P1 receptor agonist which was ongoing clinical or pre-clinical research in international society. It has been applied for domestic and international compound patent protection.
 
通過體外對S1P₁和S1P₃受體的選擇性試驗、正常大鼠體內減低淋巴細胞作用強度試驗、對大鼠心率的影響試驗，以及在大鼠體內的初步藥代特性研究，結合化學合成工藝難度分析，確定化合物IMMH001、IMMH002能有效降低外周血淋巴細胞活性而對心率影響較小。
With the selectivity test of S1P1 and S1P3 receptor in vitro, the strength test of reducing lymphocytes in normal rats, the heart rate test of rats, and the preliminary pharmacokinetic characteristics research of rats in vivo, together with the difficulty analysis of chemical synthesis, it was determined that the compound IMMH001, IMMH002 could effectively reduce the activity of peripheral blood lymphocyte with less effects on heart rate.
