[EX Q]: Paragraph: Norovirus infection constitutes the primary cause of acute viral gastroenteritis. There are currently no vaccines or norovirus-specific antiviral therapeutics available for the management of norovirus infection. Norovirus 3C-like protease is essential for viral replication, consequently, inhibition of this enzyme is a fruitful avenue of investigation that may lead to the emergence of anti-norovirus therapeutics. We describe herein the optimization of dipeptidyl inhibitors of norovirus 3C-like protease using iterative SAR, X-ray crystallographic, and enzyme and cell-based studies. We also demonstrate herein in vivo efficacy of an inhibitor using the murine model of norovirus infection. . Accession Codes. The coordinates and structure factors for norovirus 3CL protease in complex with inhibitors have been deposited to the Protein Databank with the accession codes NVpro:17 (4XBB), NVPro:44-h (4XBC) and NVPro:44-o (4XBD). We initially focused on the design of peptidyl transition state inhibitors of NV 3CLpro that incorporate in their structure a recognition element (a peptidyl fragment) that is congruent with the known substrate specificity of the enzyme (vide supra) and a warhead (aldehyde or α-ketoamide), latent warhead (bisulfite adduct) or transition state mimic (α- Kankanamalage et al. The synthesized compounds were evaluated for their inhibitory activity against NV 3CLpro, as well as their anti-norovirus activity in a cell-based replicon system, as previously Kankanamalage et al. In order to evaluate the specific interactions between the enzyme and the αhydroxyphosphonate inhibitors, inhibitor 17 was incubated with NV 3CLpro in Tris buffer, pH 8.0. Surprisingly, the enzyme-inhibitor complex formed corresponded to the complex formed between aldehyde 16 and 3CL protease. The formation of this complex indicates initial non-enzymatic (buffer)-or enzyme-catalyzed conversion of α-hydroxyphosphonate 17 to the corresponding aldehyde 16, followed by the formation of a tetrahedral adduct with the active site cysteine (Cys139). Studies aimed at ascertaining the validity of this hypothesis are in progress. The ensemble of hydrogen bonding and hydrophobic interactions Kankanamalage et al.

[EX Q]: Paragraph: The mucus-dwelling parasite Ostertagia ostertagi is one of the most important gastrointestinal nematodes in cattle. Our group has previously demonstrated the protective capacity of a vaccine against this parasite based on a native activation-associated secreted protein ASP1 (nASP) in combination with the saponin adjuvant QuilA. The aim of the current study was to analyse the effect of both antigen and adjuvant on the cellular and humoral vaccine-induced immune responses by comparing the native ASP to a recombinant version expressed in Pichia pastoris (pASP) and replacing QuilA by Al(OH) 3 . Immunization of cattle with the protective nASP+QuilA vaccine was associated with antigen-induced proliferation of natural killer (NK) cells combined with IFN-γ secretion and the induction of a mixed IgG1/IgG2 antibody response. ASP-specific activation and proliferation of NK cells was also observed in mice following the same vaccination regime. Replacing QuilA by Al(OH) 3 or nASP by pASP significantly decreased the capacity of the vaccines to trigger both NK cell activation and antibody responses and failed to induce protection against a challenge infection. Reduction of the structurally anchoring disulphide bonds of the nASP completely abolished its ability to induce NK cell activation and antibody responses, highlighting the importance of protein conformation for the immunostimulatory activity.

[EX Q]: Paragraph: Cyclic adenosine monophosphate (cAMP) is a crucial intracellular second messenger molecule that converts extracellular molecules to intracellular signal transduction pathways generating cell-and stimulus-specific effects. Importantly, specific phosphodiesterase (PDE) subtypes control the amplitude and duration of cAMP-induced physiological processes and are therefore a prominent pharmacological target currently used in a variety of fields. Here we tested the extracts from traditional Chinese medicine, Forsythia suspense seeds, which have been used for more than 2000 years to relieve respiratory symptoms. Using structural-functional analysis we found its major lignin, Forsynthin, acted as an immunosuppressant by inhibiting PDE4 in inflammatory and immune cell. Moreover, several novel, selective small molecule derivatives of Forsythin were tested in vitro and in murine models of viral and bacterial pneumonia, sepsis and cytokine-driven systemic inflammation. Thus, pharmacological targeting of PDE4 may be a promising strategy for immune-related disorders characterized by amplified host inflammatory response. Compound 6, 7, 9 and 13 were also tested in LPS stimulated RAW264.7 (Fig. 4A) and PBMC (Fig. 4B) cells to evaluate their ability to suppress TNF secretion. Compound 7, which is Forsythin, exhibited [IC 50 ] TNF58-10 mM in RAW264.7 and PBMC cells, which is comparable to its [IC 50 ] PDE4. Other custom designed compounds such as 6, 9 and 13 exhibited much greater potency with an [IC 50 ] towards TNF ranging from 25-400 nM. Specifically, compound 13 exhibited PDE4 Inhibitors in Forsythia PLOS ONE |
