Based on the idea of modification of sugar drugs, or transforming other active substances with sugar molecules, sixteen D-glucosamine-fluoroquinolone (FQ) derivatives were designed by combining D-glucosamine with FQs and synthesized by a multi-step reaction with shared intermediates. The assay results of anti-human pathogenic bacteria and anti-citrus canker showed that the inhibitory activities of two target molecules TM2b and TM2d against Staphylococcus aureus ATCC14125 were stronger than those of all tested positive control drugs, and the inhibitory rates of target molecules TM2m and TM2n against citrus canker were higher than that of the positive control streptomycin at the concentrations of 0.5 and 0.2 µg·mL-1, respectively, which all were worthy of further study. In this study, a series of novel molecules composed of D-glucosamine and FQs were synthesized for the first time, and super antibacterial molecules were found, which expanded the types and biological activities of D-glucosamine derivatives.

基于糖类药物的修饰或用糖类分子改造其他活性物质的思路, 将具有多种活性的D-氨基葡萄糖与氟喹诺酮类(fluoroquinolones, FQs) 进行拼合, 设计并合成了16个D-氨基葡萄糖的FQs衍生物。抗人致病菌和抗柑橘溃疡病菌活性测试发现, 2个目标分子TM2bTM2d对于金葡菌ATCC14125的抑制活性强于所有测试的阳性对照药物; 2个目标分子TM2mTM2n对柑橘溃疡病菌的抑制率在浓度分别为0.5和0.2 µg·mL-1时都高于阳性对照链霉素, 值得进一步研究。本研究首次合成了D-氨基葡萄糖与FQs拼合的新型分子, 发现了超强抑菌活性分子, 拓宽了D-氨基葡萄糖衍生物的类型及生物活性范围。

基于糖类药物的修饰或用糖类分子改造其他活性物质的思路, 将具有多种活性的D-氨基葡萄糖与氟喹诺酮类(fluoroquinolones, FQs) 进行拼合, 设计并合成了16个D-氨基葡萄糖的FQs衍生物。抗人致病菌和抗柑橘溃疡病菌活性测试发现, 2个目标分子TM2bTM2d对于金葡菌ATCC14125的抑制活性强于所有测试的阳性对照药物; 2个目标分子TM2mTM2n对柑橘溃疡病菌的抑制率在浓度分别为0.5和0.2 µg·mL-1时都高于阳性对照链霉素, 值得进一步研究。本研究首次合成了D-氨基葡萄糖与FQs拼合的新型分子, 发现了超强抑菌活性分子, 拓宽了D-氨基葡萄糖衍生物的类型及生物活性范围。

Based on the idea of modification of sugar drugs, or transforming other active substances with sugar molecules, sixteen D-glucosamine-fluoroquinolone (FQ) derivatives were designed by combining D-glucosamine with FQs and synthesized by a multi-step reaction with shared intermediates. The assay results of anti-human pathogenic bacteria and anti-citrus canker showed that the inhibitory activities of two target molecules TM2b and TM2d against Staphylococcus aureus ATCC14125 were stronger than those of all tested positive control drugs, and the inhibitory rates of target molecules TM2m and TM2n against citrus canker were higher than that of the positive control streptomycin at the concentrations of 0.5 and 0.2 µg·mL-1, respectively, which all were worthy of further study. In this study, a series of novel molecules composed of D-glucosamine and FQs were synthesized for the first time, and super antibacterial molecules were found, which expanded the types and biological activities of D-glucosamine derivatives.

Wen-wen XIE, Li FAN, Jun-hua HU, Yu-lu SONG, Tian-fu TAN, Jia LI, Na CHEN, Da-cheng YANG. Synthesis and antibacterial activity of D-glucosamine-fluoroquinolone derivatives[J]. Acta Pharmaceutica Sinica, 2023 , 58 (11) : 3389 -3399 . DOI: 10.16438/j.0513-4870.2023-0227
D-氨基葡萄糖(glucosamine, D-GlcN) 是一种天然六碳糖, 目前主要由甲壳素在酸性条件下水解得到[1]D-GlcN类化合物主要以盐酸盐[2, 3]、硫酸盐和N-乙酰氨基葡萄糖的形式存在。D-GlcN及其衍生物是软骨基质和滑液中糖胺聚糖的天然成分[4], 参与构建人体透明质酸和肝素, 能够治疗关节炎[5]; 具有抗病毒[6]、抗菌[7]等活性, 是糖基化蛋白和脂质生化合成的重要前体, 刺激蛋白多糖的合成[8], 并且可以活化NK (natural killer)、LAK (lymphokine activated killer) 细胞, 具有免疫调节作用[9]
氟喹诺酮类(fluoroquinolones, FQs) 药物是喹诺酮药物发展史上的里程碑。FQs具有较高的口服生物利用度、良好的药代动力学特性和优异的抗感染活性[10, 11], 已广泛应用于呼吸道感染、胃肠道和泌尿道交叉感染、皮肤和软组织交叉感染、慢性骨髓炎及性传播疾病等的治疗[12]。FQs还具有多种非经典生物活性, 包括抗结核、抗肿瘤、抗人类免疫缺陷病毒(HIV)、抗疟疾和抗阿尔茨海默病活性[13], 氧氟沙星、左氧氟沙星、环丙沙星(ciprofloxacin, CIP)、加替沙星(gatifloxacin, GAT)、莫西沙星已经成为耐药结核病的核心治疗药物。
基于糖类药物的修饰或用糖类分子改造其他活性物质的思路, 作者将具有药物活性的D-GlcN与FQs进行拼合, 进而设计D-GlcN的FQs衍生物。D-GlcN可以进行N-位和O-位化学修饰。N-位化学修饰, 目前国内外的研究主要涉及N-位酰化、N-位烷基化、N-位芳基化、N-位席弗碱、N-位脲类修饰等[14-16]; 生物活性研究表明, D-GlcN的N-位修饰衍生物的生物活性具有多样性, 与本课题的研究目标一致, 因此设计了图 1左端所示的目标分子模式。
选择性合成分子量尽可能小的药物分子, 是药物分子设计的重要内容。为达此目的, 作者在设想了各种类型的D-GlcN衍生物后, 最终选择1, 3, 4, 6-四-O-乙酰基氨基葡萄糖(简称4Ac-GlcN) 为D-GlcN的片段, 将目标分子进一步明确为图 1右端所示的模式。
本实验室采用保留FQs母核、对C-7位杂环的氨基进行修饰的策略, 合成了10多类分子, 获得了活性更强、毒性更低的抗菌和/或抗结核先导分子[17-22], 并且发现某些分子对柑橘溃疡病、柑橘真菌病具有很好的防治效果[23], 有的分子已开发为制剂应用于大田实验[24]。本课题继续沿用此修饰策略, 选择克林沙星(clinafloxacin, CLX)、诺氟沙星(norfloxacin, NOR)、CIP、沙拉沙星(sarafloxacin, SAR)、依诺沙星(enoxacin, ENO)、巴洛沙星(balofloxacin, BAL)、洛美沙星(lomefloxacin, LOM)、GAT 8个含有NH/NH2的FQs药物进行修饰, 期望获取活性高、结构多样的目标分子。
Linker分子必须拥有连接功能。鉴于Linker是连接D-GlcN以及FQs的胺基, 那么Linker应为多官能团分子。Linker最好分子质量小、分子刚柔性适度、代谢片段无毒。查找上市药物, 发现-CH2CO-采用较广。因此, 本课题尝试性采用-CH2CO-为Linker片段, 得到目标分子通式1 (图 2)。
依据多年药物研究经验和物理参数计算, 通式1的目标分子的水溶性可能不好。众所周知, 分子良好的水溶性可以改善药物体内的药动学特性, 增加化合物的成药性; 查找上市药物发现, 多个含有相似结构的上市药物其羟基都是未保护的。有鉴于此, 作者设计了通式2的目标分子(图 3), 希望能够改善通式1的目标分子的水溶性。
通过合成路线设计及反应条件探索, 经多步反应合成了16个尚未报道的新分子; 抗人致病菌和抗柑橘溃疡病菌活性测试, 发现了高活性分子。
将两种片段联接在一起的目标分子, 有多种合成路线。基于Linker的连接方向不同, 目标分子有合成路线1所示两条相对优化的合成路线。
与氯乙酰氯反应的起始原料不同, 所得产物不同。Route 1从FQs开始连接氯乙酰基, 合成的是TM1, 其优点是可以增加FQs的溶解度, 便于TLC监测反应进程, 但没有共同中间体, 合成工作量较大。Route 2从D-GlcN开始合成4Ac-GlcN硫酸盐IMa, 然后与氯乙酰氯反应合成共同中间体IM2, 其后与FQs反应合成TM2, 合成工作量相对较小, 但中间体监测困难。两条路线所得产物不同, 因而都加以尝试。
4Ac-GlcN的合成方法有两类: 一类是将糖分子的羟基和氨基同时乙酰化, 然后选择性地脱去氨基上的乙酰基; 另一类是先保护氨基, 随后保护羟基, 再脱去氨基保护基, 诸如邻苯二甲酸酐法[25]、二乙基乙氧基亚甲基丙二酸法[26]、对甲氧基苯甲醛法[27]及苯甲醛法等文献方法。本文参照汪林发[28]使用的第三类合成方法, 采用乙酸酐/浓硫酸法, 一步生成1, 3, 4, 6-四-O-乙酰基-α-D-氨基葡萄糖硫酸盐, 实验结果见表 1
IMa与氯乙酰氯反应生成IM2, 是典型的氨基酰化反应, 但由于氯乙酰氯是多官能团分子, 因此反应的选择性是关键。根据本实验室前期经验[29], 降温、缓慢加入酰化试剂可实现高选择性反应。实验表明, 以碳酸钾为缚酸剂, 冰浴冷却, 缓慢滴加氯乙酰氯, 可高选择性合成IM2, 实验结果见表 2
中间体IM2的收率在60%左右, 收率不高。究其原因, 一是IM2本身在紫外下无荧光, 只能通过氨基的显色反应跟踪反应进程, 因而终点把控不准确; 二是TLC监测发现, IM2在水中有一定的溶解度, 不能被二氯甲烷(DCM) 完全萃取, 因而收率降低。
IM1a~IM1h的合成与中间体IM2相同, 都是氨基的酰化反应, 因而同样采用降温、缓慢加入酰化试剂的方法合成, 实验结果见表 3
中间体IM1a~IM1h的收率能达到74.1%~99.2%, 出乎预料, 得益于溶解性不好的沙星居然能反应完全。氯乙酰氯有两个氯原子, 都有反应的可能性, 由于杂质含量不同, 因而收率有所不同。
正如前述, Linker的不同连接方向导致2种目标分子。鉴于两种分子的活性未知, 两条合成路线各有优劣, 因而两种分子的合成都进行了尝试。首先对IMaIM1a合成TM1a进行了溶剂、碱种类的探索。TLC表明, 当DMF为溶剂、DIPEA为碱时反应最完全、新点最纯, 据此进行TM1的合成, 结果见表 4
但在后续HR-MS验证中发现, 合成的分子并不是目标分子TM1, 而是IM1x与AcO-反应的产物TM1′ (合成路线2), 该AcO-可能来自于IMa合成时未除尽的乙酸酐或者IMa的AcO-的脱落。
改变各种条件, 也未得到预期分子。鉴于此, 尝试IM2FQs反应合成TM2, 并以GAT与IM2为模型反应。条件探索实验表明, 该反应的最佳条件为: 以DMF为溶剂, DIPEA作碱, 投料摩尔比为FQs∶IM2∶DIPEA = 1∶2∶1.5。按此最优条件合成, 成功获得目标分子TM2a~TM2h, 结果见表 5
TM2a~TM2h的收率在51.9%~75.3%, 整体收率中等偏上。究其原因, 在于FQs的溶解性、反应产物与杂点Rf的差异以及柱色谱操作水平。
该反应为单糖衍生物羟基保护基的脱除, 为手性结构的皂化反应。研究的关注点在于温和条件下能否选择性完全脱除。以TM2h为模型分子, 分别尝试了在LiOH/CH3OH/THF/H2O、TEA/CH3OH/H2O以及CH3ONa/CH3OH三种体系中合成TM2p, 只有在CH3ONa/CH3OH体系中反应能够顺利进行, 并成功合成目标分子TM2i~TM2p, 实验结果见表 6
TM2i~TM2p的收率在61.3%~69.6%, 主要原因在于反应后体系无明显杂点, 但由于产物本身具有极强的水溶性, 因而反应后甲醇钠的除去只能通过柱色谱来实现, 有一定的损失, 因而整体收率不高。
自青霉素问世以来, 各种天然抗菌药物和合成抗菌药物的不断出现使细菌感染性疾病得到有效控制, 为保障人类生命健康做出了卓越贡献[30, 31]。但随着抗生素与抗菌药物的广泛使用甚至滥用, 细菌耐药性快速产生。为了控制耐药菌感染, 迫切需要筛选出新的抗菌药物。
本课题选取了3株G-菌株、4株G+菌株, 用于测试中间体及TM2a~TM2p的抑菌能力, 相关结果见表 7
总体来说, 抗菌活性, 阳性对照药物FQs > TM2a~TM2p > IM2, 目标分子TM2a~TM2p对于G+菌的抑制活性强于G-菌。比较TM2a~TM2hTM2i~TM2p的活性-结构关系, 发现水溶性增强的TM2i~TM2p的活性并非一定强于脂溶性强的TM2a~TM2h, 表明化合物的水溶性可能并不是其抑菌活性的决定性因素; 比较8种阳性对照的活性发现, GAT、BAL、CLX对于所测试7株细菌的抑制活性在8种FQs中都名列前茅, 而与其对应的化合物TM2a/TM2b/TM2d以及TM2i/TM2j/TM2k的抑制活性基本也强于其他化合物, 暗示FQs可能是决定D-GlcN与FQs偶联物抗菌活性的关键因素。
对于大肠杆菌(E.coli ATCC25922)、沙门氏菌(S.enteritidis ATCC13076) 和铜绿假单胞菌(P.aeruginosa ATCC27853), 少数目标分子的抑制活性与某些阳性药物相当, 但多数目标分子的抑制活性不如阳性对照药物。对于鲍曼不动杆菌(A.baumannii ATCC19606), TM2a~TM2c的MIC值(0.164 8~0.178 1 µmol·mL-1) 小于除CLX (0.043 7 µmol·mL-1) 外的所有阳性对照药物; TM2d~TM2o (0.331 3~0.475 4 µmol·mL-1) 的MIC值小于或相当于除CLX外的所有阳性对照药物(0.332 1~0.801 7 µmol·mL-1); TM2g~TM2o的MIC值(0.361 8~0.475 4 µmol·mL-1) 小于NOR、CIP、ENO、BAL以及LOM (0.657 4~0.801 7 µmol·mL-1)。其中TM2b的MIC值(0.164 8 µmol·mL-1) 最小, 其抑制活性是除CLX外所有阳性对照药物的2.0~4.8倍。
对于藤黄微球菌(M.luteus), TM2d (0.010 6 µmol·mL-1) 的MIC值最小, 其抑制活性是NOR (0.801 7 µmol·mL-1) 的75.6倍、ENO (0.199 8 µmol·mL-1) 的18.8倍、CIP (0.048 3 µmol·mL-1) 和LOM (0.045 5 µmol·mL-1) 的4.5倍、SAR (0.020 8 µmol·mL-1) 的1.9倍。此外, TM2a (0.042 0 µmol·mL-1)、TM2b (0.020 6 µmol·mL-1)、TM2i (0.026 9 µmol·mL-1)、TM2j (0.026 3 µmol·mL-1)、TM2l (0.013 7 µmol·mL-1) 的MIC值也小于NOR、ENO、CIP、LOM, 表明它们的活性强于以上上市药物。
目标分子对金葡菌(S.aureus) ATCC25129的抑制活性, 总体上虽然不如多数阳性对照药物, 但有一半分子的MIC值小于0.052 9 µmol·mL-1, 其中TM2j (0.013 1 µmol·mL-1) 的MIC值最小, 抑制活性是NOR (0.100 2 µmol·mL-1) 和CIP (0.096 6 µmol·mL-1) 的7.4倍左右、ENO (0.049 9 µmol·mL-1) 的3.6倍。
对于金葡菌ATCC14125, 目标分子TM2b (0.005 1 µmol·mL-1) 和TM2d (0.005 3 µmol·mL-1) 的MIC值小于所有阳性对照药物(0.005 4~0.012 5 µmol·mL-1); TM2i (0.006 7 µmol·mL-1) 和TM2l (0.006 8 µmol·mL-1) 的MIC值小于除GAT外的所有阳性对照药物; TM2a (0.010 5 µmol·mL-1) 和TM2j (0.013 1µmol·mL-1) 的MIC值与除GAT外的阳性对照药物相当, 表明这些高活性化合物具有非常好的研究潜力。
柑橘溃疡病是柑橘的三大难治性疾病, 对柑橘叶片、枝梢、果实危害较重, 引致溃疡斑, 造成落叶、枯梢、落果, 从而导致果实产量降低, 大大降低果实商品性, 造成严重的经济损失, 但至今尚未发现柑橘溃疡病的根治方法[32]。本课题测试了目标分子TM2a~TM2p抑制柑橘溃疡病菌的能力, 实验结果见表 8
实验结果表明, 每个分子对柑橘溃疡病菌的抑制能力都超过阳性对照药物链霉素(LMS) 的50%, 并且脱除乙酰基的化合物TM2i~TM2p的抑制率整体上高于未脱乙酰基的TM2a~TM2h, 表明化合物的水溶性对其抑制柑橘溃疡病菌的活性具有一定的影响。在0.5 μg·mL-1的浓度下, 4个分子(TM2jTM2l~TM2n) 的抑制率高于阳性对照药物LMS, 5个分子(TM2d/TM2f/TM2i/TM2k/TM2p) 的抑制率与LMS相当。当浓度降至0.2 μg·mL-1时, 有5个分子(TM2d/TM2f/TM2m/TM2n/TM2p) 的抑制率高于LMS。特别地, TM2m的抑制活性不仅强于LMS, 而且当其浓度由0.5 μg·mL-1降至0.2 μg·mL-1时, 抑制率仅仅从62.95%降至62.54%, 显示非常强的抑菌特性, 具有进一步研究的巨大潜力。为了得到更详细的活性-剂量关系, 针对活性较好的分子, 进行了浓度梯度复筛, 实验结果见表 910
分析表中数据可知, 所测试的多数化合物对柑橘溃疡病菌的抑制活性随化合物浓度降低而减弱, 具有良好的活性-剂量关系。浓度为1 μg·mL-1时, 化合物TM2n的抑制率为73.80%, 与阳性对照药噻霉酮(SMT, 77.84%) 相当; 浓度为0.5 μg·mL-1时, 3个化合物(TM2j/TM2l/TM2p) 的抑制率与阳性对照相当, TM2n的抑制率为70.86%, 强于阳性对照药(58.52%); 浓度为0.25和0.125 μg·mL-1时, 化合物TM2jTM2n的抑制率都强于阳性对照药的53.62%。并且可以发现, 随着浓度降低, 阳性对照药的抑制活性快速下降, 多数测试分子下降速度低于阳性对照; 当浓度降至0.5 μg·mL-1及以下时, TM2jTM2n的抑制活性强于阳性对照, 且活性减弱趋势更慢, 暗指这些分子具有更强的抑菌能力, 可能具有很好的开发潜力。
本课题设计并合成了16个D-氨基葡萄糖的氟喹诺酮衍生物, 以1H NMR、13C NMR和HR-MS确证了目标分子的结构。目标分子的抗人致病菌活性结果表明, TM2系列目标分子对于G+菌的抑制活性强于G-菌, 其中TM2bTM2d对于金葡菌ATCC14125的抑制活性强于所有测试过的FQs。TM2mTM2n对柑橘溃疡病菌的抑制率在测试浓度下都高于阳性对照药LMS, 并且TM2m的抑制率随浓度降低很少, 具有进一步研究的巨大潜力。
