氘标记在制药、化学科学和材料科学中具有广泛的应用。多年来,开发用于合成氘标记化合物的有效方法,尤其是氢同位素交换 (HIE),继续受到令人印象深刻的关注。在此,我们开发了一种氮掺杂纳米级镍催化剂,用于使用 D2O 作为同位素源掺入各种氮杂环的氘。这种方法的有用性已经被 10 g 尺度用于复杂药物所证明。这种方法代表了一种实用且可扩展的氘化,空气和水稳定的纳米催化剂能够以直接的方式进行高效标记。

L-Nucleoside Analogues as Potential Antimalarials That Selectively TargetPlasmodium FalclparumAdenosine Deaminase
摘要:
The L-stereoisomer analogues of D-coformycin selectively inhibited P. falciparum adenosine deaminase (ADA) in the picomolar range (L-isocoformycin, K-i 7 pM; L-coformycin, K-i 250 pM). While the L-nucleoside analogues, L-adenosine, 2,6-diamino-9-(L-ribofuranosyl)purine and 4-amino-1-(L-ribofuranosyl)pyrazolo [3,4-d]-pyrimidine were selectively deaminated by P. falciparum ADA, L-thioinosine and L-thioguanosine were not. This is the first example of 'non-physiological' L-nucleosides that serve as either substrates or inhibitors of malarial ADA and are not utilised by mammalian ADA.

structure in which the nucleoside bridges two adjacent palladium atoms through its N(7) and the exocyclic O(6) atoms. Reaction in dmso gave the complex Pd(Pro)(Nucl)Cl in which the nucleoside act as monodentate ligands with their N(7) atom as ligation site. In aqueous solutions these complexes are quantitatively transformed to the polymeric analogues with the liberation of HCl. The nucleoside adenosine (Ado)
This invention relates to .alpha. and .beta. L-ribofuranosyl nucleosides, processes for their preparation, pharmaceutical compositions containing them, and methods of using them to treat various diseases in mammals.
