Abstract
Histone deacetylases (HDACs), a critical family of epigenetic enzymes, has emerged as a promising target for antitumor drugs. Here, we describe our protocol of virtual screening in identification of novel potential HDAC inhibitors through pharmacophore modeling, 3D-QSAR, molecular docking and molecular dynamics (MD) simulation. Considering the limitation of current virtual screening works, drug repurposing strategy was applied to discover druggable HDAC inhibitor. The ligand-based pharmacophore and 3D-QSAR models were established, and their reliability was validated by different methods. Then, the DrugBank database was screened, followed by molecular docking. MD simulation (100 ns) was performed to further study the stability of ligand binding modes. Finally, results indicated the hit DB03889 with high in silico inhibitory potency was suitable for further experimental analysis.Communicated by Ramaswamy H. Sarma.

Abstract
A glyoxalase inhibitor was synthesized and tested against Staphylococcus aureus for first time and showed MIC90 of 20 μg/ml. Henceforth, we synthesized unnatural azide derivative of the same inhibitor to improve the biological activity. In that order, an azide carboxylate was synthesized from dimethyl tartrate by tosylation and azide substitution. The synthesized, azide compound was coupled with glutathione derivative in high yield and tested against S. aureus and showed improved MIC90 of 5 μg/ml. In general, it can be also easily converted to unnatural β-amino acid in good yield. The shown methodology will be extended to study induced suicide in Burkholderia mallei, Francisella tularensis and Mycobacterium tuberculosis in future.

Abstract
Human glyoxalase II (Glx2) was overexpressed in rich medium and in minimal medium containing zinc, iron, or cobalt, and the resulting Glx2 analogues were characterized using metal analyses, steady-state and pre-steady-state kinetics, and NMR and EPR spectroscopies to determine the nature of the metal center in the enzyme. Recombinant human Glx2 tightly binds nearly 1 equiv each of Zn(II) and Fe. In contrast to previous reports, this study demonstrates that an analogue containing 2 equiv of Zn(II) cannot be prepared. EPR studies suggest that most of the iron in recombinant Glx2 is Fe(II). NMR studies show that Fe(II) binds to the consensus Zn(2) site in Glx2 and that this site can also bind Co(II) and Ni(II), suggesting that Zn(II) binds to the consensus Zn(1) site. The NMR studies also reveal the presence of a dinuclear Co(II) center in Co(II)-substituted Glx2. Steady-state and pre-steady-state kinetic studies show that Glx2 containing only 1 equiv of Zn(II) is catalytically active and that the metal ion in the consensus Zn(2) site has little effect on catalytic activity. Taken together, these studies suggest that Glx2 contains a Fe(II)Zn(II) center in vivo but that the catalytic activity is due to Zn(II) in the Zn(1) site.

Abstract
Methylglyoxal (MG) is a highly reactive cytotoxic alpha-oxoaldehyde compound and is formed endogenously via different enzymatic and non-enzymatic reactions. In plants MG is detoxified mainly via the glyoxalase system that is comprised of two enzymes, glyoxalase I and glyoxalase II. Glyoxalase I converts MG to S-D-lactoylglutathione by utilizing glutathione, while glyoxalase II converts S-D-lactoylglutathione to D-lactic acid, and during this reaction glutathione is regenerated. The presence and characterization of both glyoxalase I and II has been reported in many plants and the genes encoding these have been cloned and found to be regulated under various environmental conditions. In plants, MG has been found to be present during normal growth conditions and it accumulates to higher levels under various environmental stresses. Abiotic and heavy metal stresses induce reactive oxygen species (ROS) and MG. Overexpression of the glyoxalase pathway in transgenic tobacco and rice plants has been found to check an increase of ROS and MG under stress conditions by maintaining glutathione homeostasis and antioxidant enzyme levels. There is also evidence that in addition to glyoxalase, other pathways, such as the aldose reductase pathway, may also be involved in MG detoxification in plants. To unravel the role of MG and the glyoxalase pathway in signal transduction during environmental stress conditions in plants is a topic of future research interest. In this paper we review work on plant glyoxalases especially with respect to their role under abiotic stresses.
