Opis:
Hepatic resections are commonly associated with high morbidity and mortality. Nutrition plays an important role in reducing postoperative complications besides improvement in intensive care and perioperative management. The aim of the study was to evaluate the role of glutamine as an immunonutrient in patients undergoing hepatic resection. Material and methods. The study included 22 patients who underwent hepatectomy. Patients were randomized into two equal groups wherein group A patients received perioperative glutamine whereas group B patients served as controls. Primary outcome measures were level of serum albumin, C‑reactive protein (CRP), liver function tests and absolute neutrophil counts in the postoperative period while secondary outcome included post operative complications. Results. Glutamine decreased the CRP response in liver resection in a statistically significant manner (p=0.028) on the fifth post operative day. This may signify that glutamine decreases the post operative inflammatory response associated with liver resection. Glutamine did not have any significant effect on liver function tests. Postoperative morbidity was less in patients who received glutamine. Conclusion. Glutamine successfully blunted the CRP response in patients who received glutamine postoperatively. Decrease in morbidity following glutamine administration is an attractive area of prospective research and requires further consideration involving larger patient groups.

Opis:
Fungal infections are a growing problem in contemporary medicine, yet only a few antifungal agents are used in clinical practice. In our laboratory we proposed the enzyme L-glutamine : D-fructose-6-phosphate amidotransferase (EC 2.6.1.16) as a new target for antifungals. The structure of this enzyme consists of two domains, N-terminal and C-terminal ones, catalysing glutamine hydrolysis and sugar-phosphate isomerisation, respectively. In our laboratory a series of potent selective inhibitors of GlcN-6-P synthase have been designed and synthesised. One group of these compounds, including the most studied N3-(4-methoxyfumaroyl)-l-2,3-diaminopropanoic acid (FMDP), behave like glutamine analogs acting as active-site-directed inactivators, blocking the N-terminal, glutamine-binding domain of the enzyme. The second group of GlcN-6-P synthase inhibitors mimic the transition state of the reaction taking place in the C-terminal sugar isomerising domain. Surprisingly, in spite of the fact that glutamine is the source of nitrogen for a number of enzymes it turned out that the glutamine analogue FMDP and its derivatives are selective against GlcN-6-P synthase and they do not block other enzymes, even belonging to the same family of glutamine amidotransferases. Our molecular modelling studies of this phenomenon revealed that even within the family of related enzymes substantial differences may exist in the geometry of the active site. In the case of the glutamine amidotransferase family the glutamine binding site of GlcN-6-P synthase fits a different region of the glutamine conformational space than other amidotransferases. Detailed analysis of the interaction pattern for the best known, so far, inhibitor of the sugar isomerising domain, namely 2-amino-2-deoxy-d-glucitol-6-phosphate (ADGP), allowed us to suggest changes in the structure of the inhibitor that should improve the interaction pattern. The novel ligand was designed and synthesised. Biological experiments confirmed our predictions. The new compound named ADMP is a much better inhibitor of glucosamine-6-phosphate synthase than ADGP.
