实施例1
(1)中间体14-甲酰基-15-氯苦参碱的合成
称取20g(80mml，1eq)的苦参碱置于150ml干燥的烧杯中，加入120ml的二氯甲烷搅拌并充分溶解苦参碱，溶解后置于干燥环境备用。准备500ml干燥的三口烧瓶密封后抽真空并氮气保护，在冰浴下对三口烧瓶预降温。称取17.52g的DMF，将DMF注射到三口烧瓶中。再称取36.8g的三氯氧磷并缓慢滴加到DMF中，滴加完毕后，0摄氏度反应1h，最后将溶解好的苦参碱加入到反应液中，此时反应液从无色液体变为红棕色，撤去冰浴，让反应液缓慢升至常温并反应24h终止反应。反应后首先通过旋转蒸发仪除去DCM和部分三氯氧磷，将剩余反应液缓慢倒入过量冰水混合物中并不断搅拌20min，缓慢加入质量分数20％NaOH溶液调节pH至9～10，该过程可用pH试纸持续观测，最后反应液会从红棕色澄清溶液变为白色浑浊液。再将调节好pH的浑浊液置于60℃的水锅之中水解2h，水解完毕后有大量淡黄色固体析出，冷却至室温并自然沉淀，再用布氏漏斗抽滤同时用适量去离子水洗涤滤饼三次，将滤饼置于50℃的真空干燥箱中干燥5h，得到淡黄色粉末状的14-甲酰基-15-氯苦参碱粗产物。该粗产物用氯仿和石油醚的混合溶剂进行重结晶，在室温下缓慢挥发溶剂培养晶体，最后得到浅黄色的14-甲酰基-15-氯苦参碱晶体。
14-甲酰基-15-氯苦参碱：14-甲酰基-15-氯苦参碱，淡黄色晶体，收率91％，熔点123.9～124.1℃；1H NMR(500MHz,CDCl3)δ:9.68(s,1H,CHO-H),4.26～3.89(m,2H,11-H,5-H),3.63(t,J＝12.8Hz,1H,6-H),3.00～2.71(m,2H),2.42(dtd,J＝15.8,5.4,1.2Hz,1H),2.31(ddd,J＝15.6,9.8,5.1Hz,1H),2.01(tdd,J＝12.3,9.6,3.1Hz,2H),1.95～1.73(m,5H),1.73～1.53(m,5H),1.52～1.42(m,2H),1.37(tt,J＝14.0,4.3Hz,1H)；13C NMR(126MHz,CDCl3)δ:187.37,150.78,107.95,63.56,57.18,57.00,56.61,49.55,39.44,36.77,27.61,26.04,22.37,21.22,20.61,17.80；HRMS(+ESI):calcd for C16H23ClN2O m/z＝294.1499,[M+H]+found 295.1580.
(2)19-氨基嘧啶并苦参碱(WJ-01)的合成
分别称取10g(34mmol，1eq)14-甲酰基-15-氯苦参碱和14.1g(102mmol，3eq)无水碳酸钾于干燥的500mL的三口烧瓶中，向其加入约100mL的甲醇使14-甲醛基-15-氯苦参碱完全溶解，再缓慢加入3.25g(34mmol，leq)盐酸胍甲醇溶液，加毕，将三口烧瓶置于70℃的油浴锅中，搅拌回流8h并停止反应。加水溶解反应液底部过量的的碳酸钾和反应生成的盐，待反应液变成黄色均相溶液之后，用二氯甲烷萃取三次，合并有机相，饱和食盐水洗涤有机相两次，无水硫酸钠干燥，抽滤，直至黄色油状物变成黄色固体，该黄色固体即为19-氨基嘧啶并苦参碱粗产物，干燥后可直接用于下一步反应。
19-氨基嘧啶并苦参碱的精制方法：由于该化合物的极性较大，用(DCM/MeOH＝50/1，V/V)进行柱层析分离，浓缩收集到的纯品，此时仍为亮黄色油状物，加入乙醚，30℃加热溶解油状物直至乙醚溶液澄清，再让其在室温下慢速挥发生长晶体，最后得到浅黄色针状19-氨基嘧啶并苦参碱晶体。

(3)酰胺基嘧啶并苦参碱衍生物(WJ-02～WJ-29)的合成
称取1.5g(5mmol，1eq)19-氨基嘧啶并苦参碱于100mL干燥的三口烧瓶中，在氮气保护下将三口烧瓶置于冰浴之中。加入20ml无水DCM溶解原料，再加入0.7ml(6mmol，1.2eq)三乙胺，最后在冰浴下缓慢滴加6mmol(1.2eq)酰氯，滴加完毕后，撤去冰浴，缓慢升至室温并在室温下反应9～24h，反应终止的时间随酰氯的不同而变化，利用薄层色谱持续监测反应进程，至原料反应完全，终止反应，加入50mLDCM稀释反应液，先用饱和NaCO3洗涤反应液2～3次，收集有机相，再用饱和食盐水洗涤有机相2～3次，用无水硫酸钠干燥有机相。旋转蒸发仪浓缩有机相，最后用EA/PE体系为洗脱剂进行柱层析分离，洗脱剂的极性在EA/PE＝1.7/1(V/V)到EA/PE＝5/1(V/V)之间，合并柱层析得到的纯目标点溶液并减压浓缩，用乙醚重结晶得到酰胺基嘧啶并苦参碱系列衍生物WJ-02～WJ-29。

通过本发明制备的上述嘧啶并苦参碱衍生物(WJ-01～WJ-35)，其构成纯度在99％以上。
实施例1制备得到的化合物WJ-01～WJ-35的分子式和结构式如表1所示：
表1并嘧啶类苦参碱衍生物一览
药理实验：体外抗肿瘤活性研究
选取所有合成的目标化合物，以苦参碱为阳性对照药，选择人前列腺癌细胞DU-145、人非小细胞肺癌细胞A549、人结直肠腺癌细胞HCT15和人宫颈癌细胞HeLa为测试细胞株，采用MTT法进行了抑制细胞活性实验，具体方法为：
用DMSO将待测化合物溶解为10mmol/L的母液，苦参碱直接用培养基溶解，置于冰箱中0℃至4℃保存，测定时用培养基稀释为所需的浓度。将96孔板培养基抽离，吸取0.01mL含有不同浓度测试药品的培养基于细胞计数板中记数，计算细胞总量。向96孔板中每孔加入0.2mL细胞悬液，大约1000个细胞。12h细胞贴壁后，每孔加入20μL(5mg/mL)的MTT试剂，轻晃混匀后置于培养箱培养4h。移去上层清液每孔避光加入0.2mL DMSO，脱色摇床轻摇10min，最后用酶标仪(490nm波长)测每孔OD值。
抑制率(％)＝(OD对照组-OD实验组)*100％/(OD阴性对照组-OD空白对照组)
使用IBM SPSS Statistics软件计算出抑制率为50％的参考数值，即为IC50参考数值。每个96孔板测定时设置5个接种细胞但不加待测化合物的对照孔和5个既不接种细胞也不加待测化合物的空白孔，待测化合物每个浓度用3个孔测试，总共测试三次取平均值。结果如表2所示。
表2目标化合物的体外抗肿瘤活性
由表2可得，本发明的苦参碱并嘧啶衍生物对人前列腺癌细胞DU-145、人非小细胞肺癌细胞A549、人结直肠腺癌细胞HCT15和人宫颈癌细胞HeLa具有良好的抑制活性，均高于苦参碱的活性。
