  Biosynthetic Origin and Mechanism of Formation of the Aminoribosyl Moiety of Peptidyl Nucleoside Antibiotics

  摘要：

  Several peptidyl nucleoside antibiotics that inhibit bacterial translocase I involved in peptidoglycan cell wall biosynthesis contain an aminoribosyl moiety, an unusual sugar appendage in natural products. We present here the delineation of the biosynthetic pathway for this moiety upon in vitro characterization of four enzymes (LipM-P) that are functionally assigned as (i) LipO, an L-methionine:uridine-5'-aldehyde aminotransferase; (ii) LipP, a 5'-amino-5'-deoxyuridine phosphorylase; LipM, a UTP:5-amino-5-deoxy-alpha-D-ribose-1-phosphate uridylyltransferase; and (iv) LipN, a 5-amino-5-deoxyribosyltransferase. The cumulative results reveal a unique ribosylation pathway that is highlighted by, among other features, uridine-5'-monophosphate as the source of the sugar, a phosphorylase strategy to generate a sugar-1-phosphate, and a primary amine-requiring nucleotidylyltransferase that generates the NDP-sugar donor.

  Selective Nucleoside Triphosphate Diphosphohydrolase-2 (NTPDase2) Inhibitors: Nucleotide Mimetics Derived from Uridine-5′-carboxamide

  摘要：

  Ecto-nucleoside triphosphate diphosphohydrolases (E-NTPDases, subtypes 1, 2, 3, 8 of NTPDases) dephosphorylate nucleoside tri- and diphosphates to the corresponding di- and monophosphates. In the present study we synthesized adenine and uracil nucleotide mimetics, in which the phosphate residues were replaced by phosphonic acid esters attached to the nucleoside at the 5'-position by amide linkers. Among the synthesized uridine derivatives, we identified the first potent and selective inhibitors of human NTP`Dase2. The most potent compound was 19a (PSB-6426), which was a competitive inhibitor of NTPDase2 exhibiting a Ki value of 8.2,uM and selectivity versus other NTPDases. It was inactive toward uracil nuc leotide- activated P2Y2, P2Y4, and P2Y6 receptor subtypes. Compound 19a was chemically and metabolically highly stable. In contrast to the few known (unselective) NTPDase inhibitors, 19a is an uncharged molecule and may be perorally bioavailable. NTPDase2 inhibitors have potential as novel cardioprotective drugs for the treatment of stroke and for cancer therapy.

  We now provide in vitro data to support the functional assignment of LipL, the putative TauD enzyme from the A-90289 gene cluster, as a non-heme, Fe(II)-dependent alpha-KG:UMP dioxygenase that produces uridine-5'-aldehyde to initiate the biosynthesis of the modified uridine component of A-90289. The activity of LipL is shown to be dependent on Fe(II), alpha-KG, and O(2), stimulated by ascorbic acid,

  Naw nucleoside heteroanalogues, 5'- and 9'-desoxynucleoside selenocyanates and primary desoxysugar selenocyanates, were synthesized from activated nucleoside and sugar derivatives and a new convenient seleno nucleophile, tetrabutylammonium selenocyanate. Tresylate-based activation of hydroxy functions turned out to be most successful for formation of these selenocyanates compared with mesylate- or triflate-based activation.
