  Halogenases Enzymatic C–H activation leading to halogenation is another emerging area in biocatalysis [55,56]. Incorporation of halogen atoms during medicinal chemistry eff ;orts is a well-established practice, presenting an effective means to control the molecule’s bioactivity and physicochemical

  A growing number of other post-translational modifications are implicated in regulation of the ubiquitin system, including substrate modification by hydroxylation, glycosylation, acetylation, methylation, modification by poly(ADP-ribose) (PAR), and attachment of ubiquitin-like modifiers. The HIF1-α

  Similarly synthetic analogs of Alogliptin by replacing the cyanobenzyl group with the butynyl group have been synthesized and tested as selective DPP-4 inhibitors [7], [8]. Additionally, quinazolines [9], [10], pyridopyrimidinediones [11], pyrazolopyrimidinones [12] and pyrimidines [13] as DPP-IV in

  Since both the Ub and ISG15 systems are crucial for the innate immune response, many prokaryotic and viral pathogens have evolved ways to hijack them in order to create a “window-of-opportunity” for efficient replication. Several viral and bacterial proteins have been found to directly target these

  Methods Results Discussion MEN91507 is a potent and selective CysLT1 receptor antagonist. Guinea-pig lung membranes have been widely used for the detection and characterization of CysLT1 receptor antagonists: in this assay the high affinity (subnanomolar) binding of [3H[leukotriene D4 or [3

  In a study on the time course of a mechanism-based inactivation of CYP3A by HIV protease inhibitors, Katzenmaier et al. [37] reported that the suppression of CYP3A activity continued for threedays after the discontinuation of ritonavir. In the present study, the CYP3A activity on day 28 after a seve

  Materials and methods Results and discussion Conclusions Data about the ability of non-conventional ligands to operate class-A GPCRs have been accumulating. Specifically, increasing evidence indicates that oxysterols, oxidized derivatives of cholesterol, are involved in many activities that

  Proof-of-concept studies with disulfiram suggest the potential utility of DβH inhibitors for treatment of cocaine use disorder. In a study of 74 subjects stabilized on methadone and randomized into disulfiram and placebo groups for 10weeks, disulfiram treatment reduced cocaine-positive urines, and d

  Introduction Sphingolipid metabolism Sphingolipids, are fundamental constituents of all eukaryotic membranes and their metabolism is carried out by a broad array of anabolic and DL-Dithiothreitol with ceramide as their hub (for a review, (Hannun and Obeid, 2018)). Ceramide can be formed by mu

  Experimental procedures Introduction Protein kinases represent one of the largest enzyme XMD8-92 in the human genome and act as signaling mediators in a variety of cellular processes (Manning et al., 2002). Because many diseases are associated with aberrant protein kinase activity, targeted k

  Role of CRF1 receptors in the BNST in stress-induced relapse to cocaine seeking The seminal work of Stewart and co-workers [19] showed that rats that have extinguished their auto-administration of different drugs of abuse relapse to drug-seeking behaviour when exposed to footshock, even after a 4

  Based on the ability of CRF to modulate nociception, we hypothesized that stress leads to hyperalgesia by the activation of CRF1 and/or CRF2 receptors in the spinal cord. We tested this hypothesis using an acute forced swim as a widely used and easily reproducible stressor and grip force as a measur

  The final test that was performed was to determine whether the trigger points of the current limiters are stable across a wide temperature range. This test was performed within a thermal-vacuum chamber on each current limiter individually. All the current limiter trip currents were set to approximat
