The endoperoxide scaffold is found in numerous natural products and synthetic substances of pharmaceutical interest. main challenge to their access remains the preparation chiral compounds due weakness peroxide bond, which limits scope available or applicable methods. Here, we demonstrate how peroxycarbenium species can be trapped by silylated nucleophiles with high enantioselectivities diastereoselectivities when applicable, using a imidophosphorimidate (IDPi) as catalyst. methodology...

Dengue virus is the world's most prevalent human pathogenic arbovirus. There currently no treatment or vaccine, and solutions are urgently needed. We previously demonstrated that biflavonoids from <i>Dacrydium balansae</i>, an endemic gymnosperm New Caledonia, potent inhibitors of NS5 RNA-dependent RNA polymerase. Herein we describe structure-activity relationship study 23 compounds: <i>D. balansae</i> (<b>1</b>–<b>4</b>) araucarioides</i> (<b>5</b>–<b>10</b>), hexamethyl-amentoflavone...
A stepwise addition of 2-trimethylsilyloxyfuran (2-TMSOF) to achiral aldehydes in the presence a chiral Lewis acid, such as (R)-(1,1′-bi-2-naphthol)2Ti complex, affords corresponding butenolides [Eq. (1)] good yields with excellent ee values (70 96 % ee). This is first reported catalytic asymmetric autoinductive aldol reaction.
Several studies have reported that the tetracycline (TC) class antibiotic doxycycline (DOX) is effective against Parkinson's disease (PD) pathomechanisms. The aim of present work was three-fold: (i) Establish a model system to better characterize neuroprotection by DOX; (ii) Compare rescue effect DOX other TC antibiotics; (iii) Discover novel neuroprotective TCs having reduced activity. For that, we used cultures mouse midbrain dopamine (DA) neurons and experimental conditions iron-mediated...
We report in this study the vivo efficacy of nine 2-substituted quinolines on Leishmania amazonensis cutaneous infection murine model and infantum donovani visceral models. In case L. model, were administered orally at 25 mg/kg twice daily for 15 days. Quinolines 1, 2, 3, 7 reduced by 80 to 90% parasite burdens lesion, whereas N-methylglucamine antimoniate (Glucantime), subcutaneous injections 100 mg [28 Sb(V)] per kg body weight daily, 98%. leishmaniasis due infantum, mice treated 10 days...
Two new coumarin compounds (1 and 2), phebalosin (3), its derived artifact murralongin (4), murrangatin acetonide (5) were isolated from the leaves of Galipea panamensis. The structures 1 2 assigned as 7-{[(2R*)-3,3-dimethyloxiran-2-yl]methoxy}-8-[(2R*,3R*)-3-isopropenyloxiran-2-yl]-2H-chromen-2-one 7-methoxy-8-(4-methyl-3-furyl)-2H-chromen-2-one, respectively, on basis their spectroscopic data (primarily NMR MS).

<ns4:p>The ongoing Ebola virus epidemic has presented numerous challenges with respect to control and treatment because there are no approved drugs or vaccines for the disease (EVD). Herein is proposed simple theoretical criterion fast virtual screening of molecular libraries candidate inhibitors infection. We performed a repurposing screen 6438 from DrugBank using this selected 267 382 experimental as candidates EVD including 15 anti-malarial 32 antibiotics. An open source Web server...
