  Bioresponsive Deciduous-Charge Amphiphiles for Liposomal Delivery of DNA and siRNA

  摘要：

  生物可降解阳离子脂质是为高效递送DNA和siRNA到细胞内而开发的。这些化合物的设计起点是膜脂DOPC，设计思路是使其在遭受酸性或酶促刺激时，如lipoplex在生物介质中行进过程中遇到的那些刺激，可能失去其阳离子电荷。它们在多种细胞系（BHK-21、Calu-3、NCI-H292和A549）中显示出卓越的DNA递送效率，同时没有显著的细胞毒性。此外，其中两种化合物（碳酸酯基DOPC衍生物）能够将小干扰RNA递送至U87Luc和A549Luc癌细胞，并能介导稳定转染的荧光素酶基因有选择性地70-80%的knockdown效果。结果表明，所述的生物响应性阳离子脂质具有高度的DNA和siRNA递送活性，这对于在体内向肺部组织递送治疗性核酸来说是一个令人鼓舞的发现。

  具有有效抗癌活性的吉非替尼类似物的优化

  摘要：

  EGFR中吉非替尼（Iressa）的相互作用是氢键和通过喹唑啉和苯胺环的范德华力。但是，由于吉非替尼的吗啉代基团电子强度较弱，因此排列较差。设计并合成了一系列新的吉非替尼哌嗪子基类似物，其中吗啉代基团被各种哌嗪子基团取代。他们中的大多数表明对人类癌细胞系具有显着的抗癌活性。特别是，化合物52 – 54对癌细胞具有极好的效力。已经开发了用于合成吉非替尼中间体的会聚合成方法，该中间体可导致吉非替尼以及许多类似物。

• Method for overcoming drug resistance of EGFR mutation and cancerous stemness of human non-small cell lung carcinoma

  EGFR mutation (T790M) and cancerous stemness have shown drug resistances in human non-small-cell lung cancer (NSCLC), thus development of novel drugs in overcoming drug resistances in the NSCLC therapy is highly desired. SP101 is a novel gefitinib derivative, which can bind the ATP-binding pocket of EGFR to inhibit its EGFR kinase activity. SP101 can reduce the drug resistances of EGFR mutation (T790M) and cancerous stemness in NSCLC. SP101 induced cancer cell death and apoptosis in the gefitinib-resistant EGFR mutation (T790M) H1975 cells. SP101 inhibited phosphorylated EGFR and its downstream Survivin proteins but conversely induced Caspase 3 activation for apoptosis induction. Moreover, SP101 could decrease Oct4 protein level and reduce Survivin proteins but conversely elicited active Caspase 3 in the xenograft human H1975 lung tumors in nude mice.

  EGFR突变（T790M）和癌干细胞特性已经显示出对人非小细胞肺癌（NSCLC）药物的耐药性，因此开发新药物以克服NSCLC治疗中的药物耐药性是非常期望的。SP101是一种新型吉非替尼衍生物，它可以结合EGFR的ATP结合口袋，抑制其EGFR激酶活性。SP101可以减少NSCLC中EGFR突变（T790M）和癌干细胞特性的药物耐药性。SP101诱导了吉非替尼耐药的EGFR突变（T790M）H1975细胞的癌细胞死亡和凋亡。SP101抑制了磷酸化的EGFR及其下游的Survivin蛋白，但相反地诱导了Caspase 3的活化以诱导凋亡。此外，SP101可以降低Oct4蛋白水平，减少Survivin蛋白，但相反地在裸鼠体内异种移植的人类H1975肺肿瘤中引发活性Caspase 3。

  New carbonic anhydrase (EC 4.2.1.1) inhibitors were synthesized as potential drugs for the topical treatment of glaucoma. They were obtained by substituting the acetyl group of acetazolamide and methazolamide with bicarboxylic acids of different chain length (C4-C6). The terminal carboxyl was either kept free or esterified with alcohols of different size (C1-C12). A gamma-aminovaleric derivative was also prepared. All compounds proved active as carbonic anhydrase inhibitors in vitro, with an average IC50 of about 0.5-mu-M. Some proved also to be topically active in vivo in lowering the artificially elevated intraocular pressure in rabbits. The most active compound, carrying a succinic acid side chain, is the most soluble in aqueous buffers. Its duration of action is about 8 h and it is under evaluation as a topical antiglaucoma drug. It is hypothesized that the duration of action could be longer in compounds having both the same high water solubility and partition coefficient.

  Biolabile cationic lipids were developed for efficient intracellular delivery of DNA and siRNA. The compounds have been designed starting from the membrane lipid DOPC in a way they may loose their cationic charge when exposed to an acidic and/or enzymatic stimulus, such as those met during the journey of a lipoplex in biological media. They demonstrated remarkable efficiency to deliver DNA in various cell lines (BHK-21, Calu-3, NCI-H292, and A549), with no significant cytotoxicity. Furthermore, two of the compounds (carbonate-based DOPC derivatives) revealed able to deliver small interfering RNA in U87Luc and A549Luc cancer cells and to mediate a selective 70–80% knockdown of the stably transfected luciferase gene. The results show that the described bioresponsive cationic lipids have high DNA and siARN delivery activity which is encouraging in view of delivering a therapeutic nucleic acid to pulmonary tissues in vivo.
