Matt is the worse professor I have ever had. It is like we already know the material! He through notes impossibly fast . You will get little to no partial credit. Kiss your GPA good bye. He will destroy it.

    Phosphatidic acid (PA) is a lipid second messenger located at the intersection of several lipid metabolism and cell signaling events including membrane trafficking

    survival

    and proliferation. Generation of signaling PA has long been primarily attributed to the activation of phospholipase D (PLD). PLD catalyzes the hydrolysis of phosphatidylcholine into PA. A variety of both receptor-tyrosine kinase and G-protein-coupled receptor stimulations have been shown to lead to PLD activation and PA generation. This study focuses on profiling the PA pool upon P2Y6 receptor signaling manipulation to determine the major PA producing enzymes. Here we show that PLD

    although highly active

    is not responsible for the majority of stable PA being produced upon UDP stimulation of the P2Y6 receptor and that PA levels are tightly regulated. By following PA flux in the cell we show that PLD is involved in an initial increase in PA upon receptor stimulation; however

    when PLD is blocked

    the cell compensates by increasing PA production from other sources. We further delineate the P2Y6 signaling pathway showing that phospholipase Cβ3 (PLCβ3)

    PLCδ1

    DGKζ and PLD are all downstream of receptor activation. We also show that DGKζ is a novel negative regulator of PLD activity in this system that occurs through an inhibitory mechanism with PKCα. These results further define the downstream events resulting in PA production in the P2Y6 receptor signaling pathway.

    In this Letter

    we describe a novel three-step

    one-pot procedure for the enantioselective synthesis of N-benzyl protected morpholines and orthogonally N

    N′-protected piperazines with chiral alkyl groups installed at the C2 position of each heterocyclic core via organocatalysis. This methodology allows for the rapid preparation of functionalized morpholines and piperazines that are not readily accessible through any other chemistry in good to excellent % ee (55–98% ee).

    This Letter describes the on-going SAR efforts based on two scaffolds

    a PLD1-biased piperidinyl benzimidazolone and a PLD2-biased piperidinyl triazaspirone

    with the goal of enhancing PLD inhibitory potency and isoform selectivity. Here

    we found that addition of an α-methyl moiety within the PLD2-biased piperidinyl triazaspirone scaffold abolished PLD2 preference

    while the incorporation of substituents onto the piperidine moiety of the PLD1-biased piperidinyl benzimidazolone

    or replacement with a bioisosteric [3.3.0] core

    generally retained PLD1 preference

    but at diminished significance. The SAR uncovered within these two allosteric PLD inhibitor series further highlights the inherent challenges of developing isoform selective PLD inhibitors.

    Further evaluation of novel structural modifications to scaffolds that engender PLD isoform selective inhibition.

    Many common bacterial pathogens utilize quorum sensing to coordinate group behaviors and initiate virulence at high cell densities. The use of small molecules to block quorum sensing provides a means of abrogating pathogenic phenotypes

    but many known quorum sensing modulators have limitations

    including hydrolytic instability and displaying non-monotonic dose curves (indicative of additional targets and/or modes of action). To address these issues

    we undertook a structure-based scaffold-hopping approach to develop new chemical modulators of the LasR quorum sensing receptor in Pseudomonas aeruginosa. We combined components from a triphenyl derivative known to strongly agonize LasR with chemical moieties known for LasR antagonism and generated potent LasR antagonists that are hydrolytically stable across a range of pH values. Additionally

    many of these antagonists do not exhibit non-monotonic dose effects

    delivering probes that inhibit LasR across a wider range of assay conditions relative to known lactone-based ligands.

    Phospholipase D (PLD) hydrolyses cellular lipids to produce the important lipid second messenger phosphatidic acid. A PLD enzyme expressed by Pseudomonas aeruginosa (PldA) has been shown to be important in bacterial infection

    and NAPE-PLD has emerged as being key in the synthesis of endocannabinoids. In order to better understand the biology and therapeutic potential of these less explored PLD enzymes

    small molecule tools are required. Selective estrogen receptor modulators (SERMs) have been previously shown to inhibit mammalian PLD (PLD1 and PLD2). By targeted screening of a library of SERM analogues

    additional parallel synthesis

    and evaluation in multiple PLD assays

    we discovered a novel desketoraloxifene-based scaffold that inhibited not only the two mammalian PLDs but also structurally divergent PldA and NAPE-PLD. This finding represents an important first step toward the development of small molecules possessing universal inhibition of divergent PLD enzymes to advance the field.

    Discovery of desketoraloxifene analogues as inhibitors of mammalian

    Pseudomonas aeruginosa

    and NAPE phospholipase D enzymes.

    Chemical strategies to block quorum sensing (QS) could provide a route to attenuate virulence in bacterial pathogens. Considerable research has focused on this approach in Pseudomonas aeruginosa

    which uses the LuxR-type receptor LasR to regulate much of its QS network. Non-native ligands that antagonize LasR have been developed

    yet we have little understanding of the mode by which these compounds interact with LasR and alter its function

    as the receptor is unstable in their presence. Herein

    we report an approach to circumvent this challenge through the study of a series of synthetic LasR agonists with varying levels of potency. Structural investigations of these ligands with the LasR ligand-binding domain reveal that certain agonists can enforce a conformation that deviates from that observed for other

    often more potent agonists. These results

    when combined with cell-based and biophysical analyses

    suggest a functional model for LasR that could guide future ligand design.
