A comprehensive summary of NMNAT and NADK inhibitors highlighting their chemical modifications by different synthetic approaches, and structure-activity relationships depending on their potential therapeutic applications is provided.
Abstract
Nicotinamide adenine dinucleotide (NAD(+)) has a crucial role in many cellular processes, both as a coenzyme for redox reactions and as a substrate to donate ADP-ribose units. Thus, enzymes involved in NAD(+) metabolism are attractive targets for drug discovery against a variety of human diseases. Herein we focus on two of them: NMN/NaMN adenylyltransferase (NMNAT) and NAD kinase (NADK). NMNAT is a key enzyme in all organisms catalyzing coupling of ATP and NMN or NaMN yielding NAD or NaAD, respectively. NADKs are ubiquitous enzymes involved in the last step of the biosynthesis of NADP. They phosphorylate NAD to produce NADP using ATP (or inorganic polyphosphates) in the presence of Mg(2+). No other pathway of NADP biosynthesis has been found in prokaryotic or eukaryotic cells. In this review we provide a comprehensive summary of NMNAT and NADK inhibitors highlighting their chemical modifications by different synthetic approaches, and structure-activity relationships depending on their potential therapeutic applications.

A geometric approach to macromolecule-ligand interactions

TL;DR: A method to explore geometrically feasible alignments of ligands and receptors of known structure and finds distinctly different geometries that provide good steric fits seems well-suited for generating starting conformations for energy refinement programs and interactive computer graphics routines.

Poly(ADP-ribose): novel functions for an old molecule.

TL;DR: The addition to proteins of the negatively charged polymer of ADP-ribose (PAR), which is synthesized by PAR polymerases (PARPs) from NAD+, is a unique post-translational modification that regulates not only cell survival and cell-death programmes, but also an increasing number of other biological functions with which novel members of the PARP family have been associated.

Increased nuclear NAD biosynthesis and SIRT1 activation prevent axonal degeneration.

TL;DR: It is demonstrated that increased Nmnat activity is responsible for the axon-sparing activity of the Wlds protein and that SIRT1, a mammalian ortholog of Sir2, is the downstream effector of increased NMNat activity that leads to axonal protection.

Nutrient-Sensitive Mitochondrial NAD+ Levels Dictate Cell Survival

TL;DR: Rodents fasted for 48 hr show increased levels of the NAD(+) biosynthetic enzyme Nampt and a concomitant increase in mitochondrial NAD(+) and the relevance of these findings to understanding how nutrition modulates physiology and to the evolution of apoptosis is discussed.
