selected to be evaluated for in vivo antitumor activity against H22, BGC-823 and Bel-7402 in mice. In vivo testing results indicated that 12 and 13 had antitumor activity against mouse liver carcinoma H22 close to Paclitaxel and cyclophosphamide. 12 had similar antitumor activity against human gastric carcinoma BGC-823 in nude mice compared to irinotecan (3) and possessed better antitumor activity against

rigidity and changes in donor–acceptor properties, three series of nucleotideanalogs containing a P–X–HN–C(O)– residue (X=CH(OH)CH2, CH(OH)CH2CH2, CH2CH(OH)CH2) as a replacement for the P–CH2–O–CHR– fragment in acyclic nucleoside phosphonates, e.g., adefovir, cidofovir, were synthesized. EDC proved to provide good yields of the analogs from the respective ω-amino-1- or -2-hydroxyalkylphosphonates and

AbstractTo study the influence of a linker rigidity and donor–acceptor properties, the P–CH2–O–CHR– fragment in acyclicnucleoside phosphonates (e.g., acyclovir, tenofovir) was replaced by the P–CH2–HN–C(O)– residue. The respective phosphonates were synthesized in good yields by coupling the straight chain of ω-aminophosphonates and nucleobase-derived acetic acids with EDC. Based on the 1H and 13C

The monomers of peptide nucleic acidscontaining 5-halouracils (5-XU-PNA), incorporated into heptameric PNA in the middle position, have been synthesized. Thermodynamic analyses revealed that the heptameric PNA oligomer with DNA and RNA showed higher duplex stability compared to the unmodified PNA counterpart. NMR studies suggested that the electron withdrawing effect of the halogen atom increased
已经合成了包含5-卤尿嘧啶(5-XU-PNA)的肽核酸单体,该单体掺入到七聚体PNA的中间位置。热力学分析表明,与未修饰的 PNA 对应物相比,具有 DNA 和 RNA 的七聚 PNA 寡聚物表现出更高的双链体稳定性。NMR研究表明卤素原子的吸电子效应增加了XU-A氢键的强度。
