  摘要：

  据报道，在DMF中使用二环己基碳二亚胺和N-羟基琥珀酰亚胺使L-和D-3'-氨基-2'，3'-二脱氧核苷2-5与N -BOC保护的氨基酸6和13缩合，得到N -BOC保护的酰氨aminonucleosides 7- 9和14中51-81％的产率。用三氟乙酸脱保护后，相应的未保护的新的嘌呤霉素10-12和15类似物以43-56％的产率获得。使用HIV（HTLV-III B染色）感染的MT-4细胞作为靶标系统，这些化合物未显示任何显着的抗病毒活性。

• Nucleoside–amino acid conjugates: An alternative route to the design of ribonuclease A inhibitors
  作者：Joy Debnath、Swagata Dasgupta、Tanmaya Pathak

  日期：2009.7

  Nucleoside-amino acid conjugates have been employed to inhibit the ribonucleolytic activity of ribonuclease A (RNase A) and affect the protonation/deprotonation equilibrium of its active site histidine residues. Agarose gel and precipitation assays indicate inhibition of RNase A activity by these molecules with a possible role of the polar side chains of the amino acids in RNase A inhibition. Kinetic experiments demonstrated that the mode of inhibition is competitive in nature with inhibition constants (K-i) in the micromolar range. The nucleoside-serine conjugate occupies the active site of RNase A and preferential perturbs the pK(a) value of His-119 by its 'free amino group' as found from H-1 NMR studies. Docking studies revealed that the free amino groups of the most active compounds are within hydrogen bonding distance of His-119 in inhibitor-RNase A complexes. (C) 2009 Elsevier Ltd.

• Inhibitors Interacting with the Magnesium Binding Site of Reverse Transcriptase: Synthesis and Biological Activity Studies of 3′-(Ω-Amino-Acyl) Amino-3′-Deoxy-Thymidine

  Active site of reverse transcriptase contains carboxylate groups involved in the magnesium binding. We prepared some nucleoside analogs which could bind to these carboxylates preventing the binding of nucleotides. To the 3'-amino-3'-deoxy-thymidine, different N-protected omega-amino-acids were bound, the protection removed to give the 3'-(omega-amino-acyl-) amino-3'-deoxy-thymidines in good yield. Some showed moderate to low activity in HIV 1 replication test.
