== Disease ==
[[http://www.uniprot.org/uniprot/5NTC_HUMAN 5NTC_HUMAN]] Autosomal recessive spastic paraplegia type 45. The disease is caused by mutations affecting the gene represented in this entry.<ref>PMID:24482476</ref>  
== Function ==
[[http://www.uniprot.org/uniprot/5NTC_HUMAN 5NTC_HUMAN]] May have a critical role in the maintenance of a constant composition of intracellular purine/pyrimidine nucleotides in cooperation with other nucleotidases. Preferentially hydrolyzes inosine 5'-monophosphate (IMP) and other purine nucleotides.

== Publication Abstract from PubMed ==
The development of cytosolic 5'-nucleotidase II (cN-II) inhibitors is essential to validate cN-II as a potential target for the reversion of resistance to cytotoxic nucleoside analogues. We previously reported a fragment-based approach combined with molecular modelling, herein, the selected hit-fragments were used again in another computational approach based on the Ilib-diverse (a software enabling to build virtual molecule libraries through fragment based de novo design) program to generate a focused library of potential inhibitors. A molecular scaffold related to a previously identified compound was selected and led to a novel series of compounds. Ten out of nineteen derivatives showed 50-75% inhibition on the purified recombinant protein at 200muM and among them three derivatives (12, 13 and 18) exhibited Ki in the sub-millimolar range (0.84, 2.4 and 0.58mM, respectively). Despite their only modest potency, the cN-II inhibitors showed synergistic effects when used in combination with cytotoxic purine nucleoside analogues on cancer cells. Therefore, these derivatives represent a family of non-nucleos(t)idic cN-II inhibitors with potential usefulness to overcome cancer drug resistance especially in hematological malignancies in which cN-II activity has been described as an important parameter.
