• Amino and carboxy functionalized modified nucleosides: A potential class of inhibitors for angiogenin

  The 3'-amino and carboxy functionalize thymidines execute their ribonucleolytic inhibition activity for angiogenin. These modified nucleosidic molecules inhibit the ribonucleolytic activity of angiogenin in a competitive manner like the other conventional nucleotidic inhibitors, which have been confirmed from kinetic experiments. The improved inhibition constant (K-i) values 427 +/- 7, 775 +/- 6 mu M clearly indicate modified nucleosides are an obvious option for the designing of inhibitors of angiogenesis process. The chorioallantoic membrane (CAM) assay qualitatively suggests that amino functionalized nucleosides have an effective potency to inhibited angiogenin-induced angiogenesis. Docking studies further demonstrate the interaction of their polar amino group with the P-1 site residues of angiogenin, i.e., His-13 and His-114 residues. (C) 2013 Elsevier Inc. All rights reserved.
• Nucleoside–amino acid conjugates: An alternative route to the design of ribonuclease A inhibitors

  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.

  Condensation of L- and D-3′-amino-2′,3′-dideoxynucleosides 2–5 with N-BOC-protected aminoacids 6 and 13 using dicyclohexylcarbodiimide and N-hydroxysuccinimide in DMF is reported to give the N-BOC-protected acylamino aminonucleosides 7–9 and 14 in 51–81% yield. After deprotection using trifluoroacetic acid the corresponding unprotected new analogues of puromucin 10–12 and 15 were obtained in 43–56%
