    (A) 1H NMR data showing the chemical shifts. Spectra of LL-37 (left panel) or LL-18 (right panel) peptide in the absence or presence of EV71 virus (green line) or CVB5 virus (red line). (B-C) 293T cells cotransfected with GFP or GFP-tagged LL-18 (B) or LL-37 (C) and HA-tagged VP1, VP2, or VP3 plasmids were immunoprecipitated with anti-HA antibody, and interactions between LL-18 and viral structural proteins were detected by anti-GFP antibody.</p

    Enantioselective Synthesis of (−)-LL-C10037α from Benzoquinone

    No full text
    The enantioselective total synthesis of the Streptomyces metabolite (−)-LL-C10037α has been accomplished in 10 steps and 20% overall yield. An early chiral intermediate was resolved with Candida rugosa lipase to provide (+)-5 with an enantiomeric excess ≥98%. The synthesis is notable in that no protecting groups are required and that all carbons in the core structure of LL-C10037α are derived from the readily available p-benzoquinone

    (A) Molecular docking model of LL-18 with EV71 virion. EV71 capsid proteins VP1 (green), VP2 (pink), and VP3(blue), all interact with LL-18 displayed in red sticks (left panel). The amino acid residues of capsid protein interacting with both LL-18 and SCARB2 are indicated (right panel). (B) 293T cells expressing SCARB2-Flag were lysed and cell lysates were incubated with EV71 virus in the absence or presence of the indicated amount of LL-18. Cell lysates were then immunoprecipitated with anti-Flag antibody and the precipitated virus was determined with anti-VP1 antibody. (C) 293T cells expressing Annexin 2-Flag were lysed and cell lysates were incubated with EV71 virus in the absence or presence of LL-18. Cell lysates were then immunoprecipitated with anti-Flag antibody and the precipitated virus was determined with anti-VP1 antibody.</p

    (A) mEV71 was pre-treated with PBS or LL-18 and used to infect 6-day old ICR mice. The survival rate of mice infected with the mEV71 virus with or without LL-18 was recorded. (B) Mice infected with the mEV71 virus with or without LL-18 pre-treatment were sacrificed 1 day post infection (d.p.i.) and viral titers from brain and muscle tissues were determined. ***, P<0.001. (C) H&E staining of muscle tissue from mice infected with the mEV71 virus with or without LL-18. Blue arrows indicate infiltrated neutrophils. Bar, 20μm.</p

    (A) RD cells were pre-incubated with indicated amounts of LL-18, FF-18, DL-37, or LL-37 for 2 hrs before they were washed extensively to remove unbound peptides. Cells were then infected with the EV71 virus (MOI = 1) and cell viability was determined 24 h.p.i. Values were normalized to uninfected RD cells. ***, P1H NMR spectra of FF-18 peptide in the absence or presence of EV71 virus (green line) or CVB5 virus (red line). (TIF)</p
