 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. 布格呋喃是名贵中药沉香提取物沉香呋喃的衍生物。《本草纲目》记载：沉香有清人神，益气合神等作用。70年代初，中国医学科学院药物研究所即已观察到沉香精油具有一定的镇静催眠作用，因此对沉香呋喃天然化合物进行了立体选择性合成和结构改造，合成了一系列新的衍生物，经过药效学和毒理学筛选，发现布格呋喃具有显著的抗焦虑活性，毒副作用较低，无依赖性和耐受性。 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. 药效试验显示，布格呋喃具有稳定的抗焦虑作用。其抗焦虑强度接近安定。在12种焦虑模型中, 布格呋喃均有量-效相关的抗焦虑作用，其抗焦虑谱与安定相同而明显宽于丁螺环酮。且重复给药时，布格呋喃的抗焦虑作用不发生耐受性（且有逐渐增强的趋势），也没有停药反应。在单独给药时，布格呋喃只有镇静效应，无论多大剂量和给药途径，都没有催眠作用。布格呋喃也无肌松与肌协调损伤作用；对学习、记忆损伤不明显；无木僵效应；对痛疼无抑制作用。 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. 在急毒试验中，布格呋喃5 g/kg 不会引起动物死亡，也无共济失调或其它感觉-运动的明显毒性效应。因此，布格呋喃中枢神经系统毒性、副作用低于丁螺环酮。安全性药理研究结果显示布格呋喃治疗剂量范围内对犬心电图、血压、心率、及呼吸无异常影响。Beagle犬口服给予布格呋喃9个月的无明显毒副反应剂量为5 mg/kg，15mg/kg和50mg/kg剂量组除血清ALP水平升高外，体重、进食量、心电图、神经活动状况、尿生化、血液学、以及其它血清生化指标等均未见明显变化。布格呋喃对动物生殖力对仔代无明显影响，亦无遗传毒性。依赖性实验显示实验动物对布格呋喃不产生生理依赖性和精神依赖性。 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. 大鼠和犬药代动力学研究显示布格呋喃吸收较快，口服后5~10min血浆中既可检测到原形药物，10-40min血药浓度达峰，各组织均有分布，经过尿、粪排泄出体外，大鼠和人血浆蛋白结合率为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%. 布格呋喃现已完成Ⅰ期临床研究，包括单次给药和多次给药的健康人体耐受性试验、单次给药和多次给药的健康人体药代动力学研究以及食物对药代动力学影响的研究。人体耐受性研究证实本品在15~90mg剂量范围内单次和多次给药的人体耐受性良好。 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. 人体药代动力学实验结果显示：中国健康受试者单次、多次空腹及进食后口服30~120mg布格呋喃安全性和耐受性良好。中国健康男性受试者单次口服布格呋喃胶囊30mg，60mg或120mg后，吸收较为迅速，总体暴露量和最高瞬时暴露水平都随着剂量的增加而升高，但与剂量并不成比例关系，药物消除随剂量增加而减慢。进食对单次口服60mg布格呋喃胶囊的系统暴露水平有影响：达峰时间延长，血浆峰浓度下降，曲线下面积增加。单次和每日两次连续口服布格呋喃胶囊60mg或120mg后，布格呋喃被快速吸收，并在每日两次重复口服后不久达稳态。与单剂的药代动力学参数相比，重复给药后的暴露量有中度蓄积。120mg组的布格呋喃清除率低于60mg组。 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. 布格呋喃Ⅰ期临床研究报告已提交CDE，正在申报Ⅱ期临床试验。 Buagafuran Phase I clinical study report has been submitted to CDE under the application for Phase II clinical trial. 应用领域：抗焦虑症 Application field: anti-anxiety disorder 药理毒理特点：抗焦虑作用稳定，其抗焦虑强度接近安定，其中枢神经系统毒性、副作用低于丁螺环酮，无依赖性和耐受性。 Pharmacological and toxicological features: stable anxiolytic effect, its anxiolytic strength is close to Diazepam, and its central nervous system toxicity, side effects were lower than these of buspirone; it has no dependence or tolerance. 创新点和优势：与现有抗焦虑药物结构不同；重复给药时，布格呋喃的抗焦虑作用不发生耐受性（且有逐渐增强的趋势），也没有停药反应。在单独给药时，布格呋喃只有镇静效应，无论多大剂量和给药途径，都没有催眠作用。布格呋喃也无肌松与肌协调损伤作用；对学习、记忆损伤不明显；无木僵效应；对痛疼无抑制作用。 Innovations and advantages: its structure is different from the existing anti-anxiety drugs. In repeated administration, the anxiolytic effect of buagafuran does not have any tolerance have tolerance (in gradually increasing trend) or withdrawal reactions. In single administration, buagafuran only has sedative effect, no matter how much dose and what route of administration, there will be no hypnotic effects. Buagafuran also cannot relax muscle or damage the muscle coordination; the damage to learning and memory is not obvious; no stupor effect; no inhibition to pain. 开发阶段：完成Ⅰ期临床试验，30~120mg范围内安全性和耐受性良好，确定了健康人体药代动力学参数。2012年4月申报开展Ⅱ期临床试验（CXHB1200054、CXHB1200055），目前正在CDE审评。 Development stage: Phase I clinical trial was completed, safety and tolerability were good in the range of 30 to 120mg; the healthy human pharmacokinetic parameters were confirmed.

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. 系统研究显示，紫杉醇与MDP简化物的共缀物MTC-220是一个新颖、有效、安全的双功能抗肿瘤候选药物，不仅在动物体内高效抗肿瘤，而且通过减少髓样抑制细胞（MDSCs）以及调节肿瘤微环境的细胞因子水平（TNF-a等）显著地抑制恶性肿瘤的转移。MTC-220在体外可对60株人癌细胞具有与紫杉醇相类似的抗肿瘤谱；在裸鼠体内可显著抑制多种原发瘤的生长；在BALB/c小鼠和C57Bl/6小鼠可分别显著抑制高转移性乳腺癌和肺癌的转移；小鼠尾静脉注射MTC-220最大耐受剂量（138.2mg/kg）远大于紫杉醇静脉给药的半数致死量（25mg/kg）。MTC-220理化性质得以改善，其制剂可避免使用致敏性的环氧乙烯蓖麻油，为实现低剂量多次静脉注射给药以提高抗肿瘤及抗肿瘤转移效果提供了基本依据。所有实验结果均显示：MTC-220极有望开发为新颖的抗肿瘤及抗肿瘤转移的双功能药物。 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. 目前，国内外无类似报道及药物上市，原创性强。MTC-220及其系列化合物具有我国自主知识产权，发明专利201180007150.X已进入实审阶段，共缀物制备工艺专利已获得受理号201210361925.X。 At present, no similar reports or drugs in the market in China, its originality is powerful.

S1P1受体激动剂（临床前研究） S1P1 Receptor Agonist (Preclinical study) S1P1受体（Sphingosine-1-Phosphate Receptor，5个亚型S1P1~5）激动剂是新型免疫抑制剂，通过诱导外周循环系统中的淋巴细胞回到淋巴结，即“归巢”，降低外周循环中的淋巴细胞数量而达到治疗自身免疫性疾病的目的。该类药物既不影响粒细胞和单核细胞活性，也不损害淋巴细胞和造血系统，并且淋巴细胞对外界抗原的记忆仍然保存，与传统免疫抑制药物相比，对自身免疫系统毒性较小。该类药物的代表是Fingolimod（FTY720），由诺华制药公司开发，已于2010年9月上市，用于多发硬化症治疗。但是临床应用中发现，FTY720有致患者心动过缓的不良反应，与其同时激动S1P3受体有关。因此，开发选择性更高的S1P1受体激动剂成为开发治疗自身免疫性疾病药物的方向。 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. 中国医学科学院药物研究开展了系统的S1P1选择性激动剂研究，对200余个新化合物的体内外活性评价发现多个化合物具有选择性S1P1受体激动作用，降低外周血淋巴细胞的活性与FTY720相当或略强，但无心动过缓副作用。与目前国际上正在进行临床或临床前研究的新型S1P1受体激动剂作用强度相当。已申请国内、国际化合物专利保护。 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. 通过体外对S1P1和S1P3受体的选择性试验、正常大鼠体内减低淋巴细胞作用强度试验、对大鼠心率的影响试验，以及在大鼠体内的初步药代特性研究，结合化学合成工艺难度分析，确定化合物IMMH001、IMMH002能有效降低外周血淋巴细胞活性而对心率影响较小。 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. 初步药效学筛选试验显示，两种化合物分别对类风湿性关节炎模型和银屑病模型具有较好的疗效。 The preliminary pharmacodynamic screening test showed that the two compounds had a good therapeutic effect on the model of rheumatoid arthritis and psoriasis. 药代动力学研究显示，IMMH001口服生物利用度为20.2%，IMMH002口服生物利用度为48.6%；IMMH001体内消除半衰期较短，为4-7h，IMMH002半衰期较长，达20-26h；两种化合物在人、猴、鼠肝微粒体中较为稳定，对CYP2E1有轻度抑制作用，各原形药及其磷酸化产物对其他CYPs活性均无明显影响，两种化合物及其磷酸化产物（10mM）体外与大鼠、犬、猴及人血浆蛋白高度结合（90-99.64％），且无明显种属差异。 The pharmacokinetic study showed that the oral bioavailability of IMMH001 was 20.2%, and the oral bioavailability of IMMH002 was 48.6%; the elimination half-life of IMMH001 was shorter in the body, which was 4-7h; and the half-life of IMMH002 was longer, which was 20-26h; the two compounds were relatively stable in liver microsomes of human, monkey and rat, and it could slightly inhibit CYP2E1, each prototype drug and its phosphorylated products had no significant affects on the activity of other CYPs. The two compounds and its phosphorylated products (10mM) were highly bound (90-99.64%) with plasma protein of rat, dog, monkey and human in vitro, and there was no obvious species differences. 初步安全性评价显示，正常昆明小鼠一次性灌胃给予IMMH001和IMMH002各500mg/kg（n=4, 雌雄各半），连续观察14天，无明显不良症状，动物体重增加。化合物遗传毒性（微生物回复突变试验）的检测，提示IMMH001和IMMH002及其相应的磷酸化产物的Ames试验结果均为阴性。IMMH001和IMMH002对心脏hERG钾电流抑制作用的IC50（μM）分别为6.57和8.07，而IMMH001-P和IMMH002-P对hERG钾电流抑制作用的IC50均大于100μM。 The preliminary safety evaluation showed that, normal Kunming mice were respectively administrated 500mg/kg IMMH001 and IMMH002 in one gavage (n = 4, male and female for half), observed for 14 consecutive days, no significant adverse symptoms, animal body weight was increased. Compound genotoxicity (microbial reverse mutation assay) detection suggested that the test results of IMMH001 and IMMH002 and their corresponding phosphorylation products Ames were negative. IC50 (μM) of IMMH001 and IMMH002 to the inhibition of cardiac hERG potassium current was 6.57 and 8.07, respectively; and IC50 (μM) of IMMH001-P and IMMH002 of-P to the inhibition of hERG potassium current were greater than 100μM. 上述结果提示，IMMH001和IMMH002均具有较好的理化性质和药代特性，各有其特点，显示了进一步开发的前景。 预计2014年末申报临床研究。 The above results suggested that IMMH001 and IMMH002 had better physicochemical properties and pharmacokinetic characteristics, and each had its own characteristics, showing the prospects for further development.
