There is one exact (name or code) match for l-glutamine

 
Glutamine is a non-essential amino acid present abundantly throughout the body and is involved in many metabolic processes. It is synthesized from glutamic acid and ammonia. It is the principal carrier of nitrogen in the body and is an important energy source for many cells. Supplemental L-glutamine's possible immunomodulatory role may be accounted for in a number of ways. L-glutamine appears to play a major role in protecting the integrity of the gastrointestinal tract and, in particular, the large intestine. During catabolic states, the integrity of the intestinal mucosa may be compromised with consequent increased intestinal permeability and translocation of Gram-negative bacteria from the large intestine into the body. The demand for L-glutamine by the intestine, as well as by cells such as lymphocytes, appears to be much greater than that supplied by skeletal muscle, the major storage tissue for L-glutamine. L-glutamine is the preferred respiratory fuel for enterocytes, colonocytes and lymphocytes. Therefore, supplying supplemental L-glutamine under these conditions may do a number of things. For one, it may reverse the catabolic state by sparing skeletal muscle L-glutamine. It also may inhibit translocation of Gram-negative bacteria from the large intestine. L-glutamine helps maintain secretory IgA, which functions primarily by preventing the attachment of bacteria to mucosal cells. L-glutamine appears to be required to support the proliferation of mitogen-stimulated lymphocytes, as well as the production of interleukin-2 (IL-2) and interferon-gamma (IFN-gamma). It is also required for the maintenance of lymphokine-activated killer cells (LAK). L-glutamine can enhance phagocytosis by neutrophils and monocytes. It can lead to an increased synthesis of glutathione in the intestine, which may also play a role in maintaining the integrity of the intestinal mucosa by ameliorating oxidative stress. The exact mechanism of the possible immunomodulatory action of supplemental L-glutamine, however, remains unclear. It is conceivable that the major effect of L-glutamine occurs at the level of the intestine. Perhaps enteral L-glutamine acts directly on intestine-associated lymphoid tissue and stimulates overall immune function by that mechanism, without passing beyond the splanchnic bed. Glutamine is used for nutritional supplementation, also for treating dietary shortage or imbalance.

Daprodustat (GSK1278863) is a low nanomolar hypoxia-inducible factor (HIF) prolyl hydroxylase (PHD) inhibitor, that increases HIF stability and action. In preclinical studies, Daprodustat stabilizes HIFα in cell lines, resulting in the production of increased levels of erythropoietin (EPO). In normal mice, a single dose of Daprodustat induced significant increases in circulating plasma EPO but only minimal increases in plasma vascular endothelial growth factor (VEGF-A) concentrations. Daprodustat significantly increased reticulocytes and red cell mass parameters in pre-clinical species following once-daily oral administration and has demonstrated an acceptable nonclinical toxicity profile supporting continued clinical development. In a phase 1 study, Daprodustat was well tolerated and increased erythropoietin (EPO) levels in apparently healthy individuals proportional to dose. In phase 2a studies in non–dialysis-dependent chronic kidney disease (NDD CKD) and end-stage renal disease Daprodustat 4-10 mg once-daily produced the dose-dependent increase in hemoglobin relative to placebo. The Phase III programme for the drug includes two studies evaluating its safety and efficacy compared to recombinant human erythropoietin in dialysis-dependent subjects with anemia associated with CKD (ASCEND-D) and in non-dialysis dependent patients with the condition (ASCEND-ND).

BioLineRx Ltd has developed BL-8040, a short peptide for the treatment of solid tumors, acute myeloid leukemia, or AML, and stem-cell mobilization for bone-marrow transplantation. BL-8040 acts as CXCR4 antagonist. CXCR4 is a chemokine receptor that is directly involved in tumor progression, angiogenesis, metastasis, and cell survival. In February 2019 US Food and Drug Administration (FDA) has granted Orphan Drug Designation to BL-8040, for the treatment of pancreatic cancer. Previously FDA had granted Orphan Drug Designation for the treatment of acute myeloid leukemia and stem-cell mobilization.

Biafungin (formerly SP 3025 or CD101), a highly stable echinocandin and an antifungal drug that was studied against panels of Candida and Aspergillus clinical isolates. Biafungin was involved in phase II clinical trials in the treatment of acute moderate to severe vulvovaginal candidiasis. Seachaid Pharmaceuticals invented this drug. Then Cidara Therapeutics acquired a worldwide exclusive license to develop and commercialize the drug.
Sotagliflozin (LX4211) is an orally-delivered small molecule compound that is currently in development for the treatment of type 1 and type 2 diabetes mellitus. Sotagliflozin (LX4211) inhibits both sodium-glucose cotransporter type 2, or SGLT2, a transporter responsible for most of the glucose reabsorption performed by the kidney, and sodium-glucose cotransporter type 1, or SGLT1, a transporter responsible for glucose and galactose absorption in the gastrointestinal tract, and to a lesser extent than SGLT2, glucose reabsorption in the kidney. Combining SGLT1 and SGLT2 inhibition in a single molecule would provide complementary insulin-independent mechanisms to treat diabetes.

Trofinetide (NNZ 2566), a proprietary small molecule analogue of glycine-proline-glutamate [Glypromate®], is being developed by Neuren Pharmaceuticals for the treatment of brain injuries, fragile X syndrome, Rett syndrome. Trofinetide is a synthetic analogue of a naturally occurring neurotrophic peptide derived from IGF-1, a growth factor produced by brain cells. In animal models, trofinetide exhibits a wide range of important effects including inhibiting neuroinflammation, normalizing the role of microglia and correcting deficits in synaptic function. Trofinetide is being developed both in intravenous and oral formulations for a range of acute and chronic conditions. The intravenous form of trofinetide is presently in a Phase 2 clinical trial in patients with moderate to severe traumatic brain injury. The oral form of trofinetide is in Phase 2 development in Rett syndrome, Fragile X syndrome and mild traumatic brain injury (concussion). Trofinetide has been granted Fast Track Status and Orphan Drug Designation in the U.S. and Orphan Drug Designation in Europe for both Rett syndrome and Fragile X syndrome.
Maribavir (previously known as 1263W94) is a novel benzimidazole riboside compound. This drug was in phase III of clinical trial for the prevention of cytomegalovirus (CMV) infections in transplant patients, sponsored by ViroPharma. However, drug failed to demonstrate a higher efficacy rate than the placebo. Maribavir has activity against cytomegalovirus and Epstein-Barr virus (EBV), but not against other human herpesviruses. Maribavir’s mechanism of action is unique and is complex compared to the currently approved antivirals for CMV. Maribavir inhibits the viral UL97 kinase rather than the viral DNA polymerase. The UL97 kinase is important for viral DNA elongation, DNA packaging, and nuclear egress of encapsidated viral DNA. In addition, maribavir inhibits the EBV DNA polymerase processivity factor (BMRF1), reduces the level of certain EBV glycoproteins, and inhibits viral transcription. However, future work will be designed to address the interaction of MBV and BGLF4 and to evaluate the mechanisms through which maribavir downregulates viral transcripts. BGLF4 belongs to the family of conserved herpesvirus PKs, which includes HCMV UL97, HSV UL13, and HSV US3. Maribavir does need to be phosphorylated for its activity.
