AI Article Synopsis

  • Researchers have created a new series of selective inhibitors for a specific enzyme called mPGES-1, based on a compound known as MK-886.
  • The most effective compounds, identified as 23 and 30, demonstrate strong inhibition of mPGES-1 at very low concentrations and show at least 100 times more selectivity compared to other similar enzymes and compounds.
  • These inhibitors successfully reduce PGE2 production in cell tests, although their effectiveness and selectivity are lower in these biological assays compared to the isolated enzyme tests.

Article Abstract

A series of potent and selective inhibitors of the inducible microsomal PGE2 synthase (mPGES-1) has been developed based on the indole FLAP inhibitor MK-886. Compounds 23 and 30 inhibit mPGES-1 with potencies in the low nanomolar range and with selectivities of at least 100-fold compared to their inhibition of mPGES-2, thromboxane synthase and binding affinity to FLAP. They also block the production of PGE2 in cell based assays but with a decreased potency and more limited selectivity compared to the enzyme assays.

Constitutive loss of kynurenine-3-monooxygenase changes circulating kynurenine metabolites without affecting systemic energy metabolism.

Am J Physiol Endocrinol Metab

January 2025

Kynurenic acid (KYNA) and quinolinic acid (QUIN) are metabolites of the kynurenine pathway of tryptophan degradation with opposing biological activities in the central nervous system. In the periphery, KYNA is known to positively affect metabolic health, whereas the effects of QUIN remain less explored. Interestingly, metabolic stressors, including exercise and obesity, differentially change the balance between circulating KYNA and QUIN.

Chikungunya virus (CHIKV) is an arthritogenic alphavirus that has re-emerged to cause large outbreaks of human infections worldwide. There are currently no approved antivirals for treatment of CHIKV infection. Recently, we reported that the ribonucleoside analog 4'-fluorouridine (4'-FlU) is a highly potent inhibitor of CHIKV replication, and targets the viral nsP4 RNA dependent RNA polymerase.

Trazodone, dibenzoylmethane and tauroursodeoxycholic acid do not prevent motor dysfunction and neurodegeneration in Marinesco-Sjögren syndrome mice.

PLoS One

January 2025

Department of Neuroscience, Laboratory of Prion Neurobiology, Istituto di Ricerche Farmacologiche Mario Negri IRCCS, Milan, Italy.

There is no cure for Marinesco-Sjögren syndrome (MSS), a genetic multisystem disease linked to loss-of-function mutations in the SIL1 gene, encoding a BiP co-chaperone. Previously, we showed that the PERK kinase inhibitor GSK2606414 delays cerebellar Purkinje cell (PC) degeneration and the onset of ataxia in the woozy mouse model of MSS. However, GSK2606414 is toxic to the pancreas and does not completely rescue the woozy phenotype.

Aluminum Induces Neurotoxicity through the MicroRNA-98-5p/Insulin-like Growth Factor 2 Axis.

ACS Chem Neurosci

January 2025

Department of Occupational Health, School of Public Health, Shanxi Medical University, Taiyuan, Shanxi 030001, China.

Aluminum is a well-known and widely distributed environmental neurotoxin. This study aimed to investigate the effect of miR-98-5p targeting insulin-like growth factor 2 (IGF2) on aluminum neurotoxicity. Thirty-two Sprague-Dawley rats were randomly divided into four groups and administered 0, 10, 20, and 40 μmol/kg maltol aluminum [Al(mal)], respectively.
