3'-叠氮胸苷(AZT)是第一个被批准用于治疗人类免疫缺陷病毒(HIV)的抗病毒药物。据报道,点击 AZT 的 3'-叠氮基团的努力并未产生对 HIV 或任何其他病毒具有活性的 1,2,3-三唑。我们在此报告了第一个 AZT 衍生的 1,2,3-三唑,具有亚微摩尔抗 HIV-1 效力。通过单复制周期测定证实了基于细胞病变效应(CPE)的测定中观察到的抗病毒活性。结构-活性-关系 (SAR) 研究揭示了抗病毒活性的两个关键结构特征:庞大的芳环和三唑上的 1,5-取代模式。相应三磷酸盐的生化分析显示,与 AZT 相比,ATP 介导的核苷酸切除效率较低,这与分子模型一起表明了三唑优先易位到 HIV 逆转录酶 (RT) P 位点的机制。这一机制得到了观察到的三唑类似物对 AZT 抗性 HIV 变体的耐药性倍数降低的证实(AZT 为 9 倍,而 AZT 为 56 倍)。

Tertiary-butoxycarbonyl (Boc) – A strategic group for N-protection/deprotection in the synthesis of various natural/unnatural N-unprotected aminoacid cyanomethyl esters
available 4M HCl in 1,4-dioxane solution (2–4 equiv); acetonitrile, 0 °C, 2–4 h was a suitable condition. This condition was generalized and successfully applied to a variety of alkyl, alkynyl, aryl, heteroaryl, benzyl, azido, spiro amino acid cyanomethylesters irrespective of the nature of the amine (primary or secondary) and the distance between the amine and ester group to achieve final deprotected

Methods and compositions are provided that utilize synthetic molecules and genetically encoded polypeptides to generate macrocyclic peptide-containing molecules with a hybrid peptidic/non-peptidic backbone. Also provided are nucleic acid molecules, polypeptides, and methods for generating libraries of macrocyclic peptide-containing molecules with a hybrid peptidic/non-peptidic backbone. These methods can be used to increase the structural diversity of ligand libraries as well as facilitate the functional screening of these libraries to identify compound(s) with desired activity properties.
