研究方向
实验室主要研究小分子化合物化学库、天然产物、多肽/糖肽、以及“协同治疗”分子的合成方法；同时，实验室也研究高通量筛选方法用于了解分子间的相互作用、编码及解码可干扰生物活性作用的小分子化合物。实验室的目标是发现药物先导化合物并优化为药物候选物用于治疗癌症及感染性疾病。
科学贡献
刘刚教授是我国最早从事组合化学和化学生物学研究者之一，成功搭建了由高通量合成技术、高通量现代分析技术、药物化学、有机化学、高分子化学（树脂）、计算化学、自动化技术、生物筛选技术、数据管理系统、以及样品保存和质控分析方法等多学科和技术支撑的系统组合化学技术平台，被专家鉴定为“整体处于国际先进水平”。多年来在小分子杂环化合物化学库的设计与组合合成、多肽化学以及多肽模拟物化学、有机化学、药物化学、以及免疫治疗、抗肿瘤和抗感染性疾病的药物研究方面都积累了丰富的研究经验，取得了一些重要研究结果。
实验室发现的紫杉醇与胞壁酰二肽模拟物的共缀物“康莫他赛”，设计为协同抑制肿瘤微环境内的炎性细胞因子，进而抑制肿瘤的转移性生长，目前已申报SFDA并进入实审阶段等待批准临床研究。
Significance: Naturally occurring (+)-calanolide A was active against R Mtb. The present report details the design, synthesis, anti-mycobacterial activities and structure–activity relationships of synthetic calanolides. This study identified potent dual-active nitro-containing calanolides with minimal in vitro toxicity that was cidal to axenic Mtb (both replicating and non-replicating Mtb) and Mtb in human macrophages, while sparing Gram-positive and -negative bacteria and yeast.
3.抑制肿瘤生长及转移的MDP类似物MTC-220的研究（J Med Chem 2011, 54(8): 2767-77; Glycoconj J 2008, 25: 415–425.）。
Significance: MTC-220, a conjugate of paclitaxel and a muramyl dipeptide analog has been synthesized as a novel agent of dual antitumor growth and metastasis activities. In vitro and in vivo tests show that MTC-220 retains its ability to inhibit tumor growth. It is superior to paclitaxel in its ability to prevent tumor metastasis in Lewis lung carcinoma and 4T1 tumor-bearing mice. The present studies indicate that MTC-220 suppresses myeloid derived suppressor cell accumulation in the spleen and bone marrow of tumor-bearing mice, and also represses inflammatory cytokines in tumor tissue. These results demonstrated that MTC-220 could be a potential therapeutic and preventive agent for cancer growth and metastasis.
4.交叉欧联类型的串联氯钯化/去芳香化/环化反应构建功能化的[3.2.1]桥环骨架类化合物。 (Org Lett 2015, 17(16): 4110-3.)。
Significance: A palladium-catalyzed tandem reaction is reported in this study that involves chloropalladation /cyclization and dearomative cyclization to construct tricyclic bridged [3.2.1] carbocyclic- skeleton and oxa- and aza-skeletons. In this domino process, a level of ring strain and other competitive reactions, i.e., protonolysis, b-hydride elimination, and chlorination of the C–Pd bond, were suppressed to the lowest level under mild reaction conditions.
5.新型抗HIV候选物小分子逆转录酶抑制剂F18的研究。（Antimicrob Agents Chemother. 2012, 56(1): 341-51.）。
Significance: We have previously described a newly synthesized small molecule 10-chloromethyl-11-demethyl-12-oxo-calanolide A (F18), a nature (+)-Calanolide A analog, as a novel NNRTI to treat HIV-1 patients (J Med Chem. 2008, 51, 1432-1446; 2010, 53, 1397-1401). This study presents F18 as a new potential drug for clinical use and also underlies new mechanism-based design for future NNRTI.

主要研究成果
1.SARS冠状病毒抗原表位的研究：对非人类灵长类动物感染的增强或中和作用(ACS Infect. Dis. 2016, 2, 361−376.)。
Significance: Severe acute respiratory syndrome (SARS) is caused by a coronavirus (SARS-CoV) and has the potential to threaten global public health and socioeconomic stability. Evidence of antibody-dependent enhancement (ADE) of SARS-CoV infection in vitro and in non-human primates clouds the prospects for a safe vaccine. Using antibodies from SARS patients, we identified and characterized SARS-CoV B-cell peptide epitopes with disparate functions. In rhesus macaques, the spike glycoprotein peptides S471–503, S604–625 and S1164–1191 elicited antibodies that efficiently prevented infection in non-human primates. In contrast, peptide S597–603 induced antibodies that enhanced infection both in vitro and in non-human primates by using an epitope sequence-dependent (ESD) mechanism. This peptide exhibited a high level of serological reactivity (64%), which resulted from the additive responses of two tandem epitopes (S597–603 and S604–625), and a long-term human B-cell memory response with antisera from convalescent SARS patients. Thus, peptide-based vaccines against SARS-CoV could be engineered to avoid ADE via elimination of the S597-603 epitope. We provide herein an alternative strategy to prepare a safe and effective vaccine for ADE of viral infection by identifying and eliminating epitope sequence-dependent enhancement of viral infection.
