Studying the chemistry of cationized triacylglycerols using electrospray ionization mass spectrometry and density functional theory computations.
J. Am. Soc. Mass Spectrom. 25(8) , 1421-40, (2014) Analysis of triacylglycerols (TAGs), found as complex mixtures in living organisms, is typically accomplished using liquid chromatography, often coupled to mass spectrometry. TAGs, weak bases not protonated using electrospray ionization, are usually ionized b... |

Nanomimics of host cell membranes block invasion and expose invasive malaria parasites.
ACS Nano 8(12) , 12560-71, (2014) The fight against most infectious diseases, including malaria, is often hampered by the emergence of drug resistance and lack or limited efficacies of vaccines. Therefore, new drugs, vaccines, or other strategies to control these diseases are needed. Here, we... |

Effect of three trifluoromethanesulfonate ionic liquids on the activity, stability and conformation of laccase.
Int. J. Biol. Macromol. 56 , 62-8, (2013) The activity, stability and conformation of laccase were first investigated in an aqueous solution of ionic liquids 1-butyl-3-methylimidazolium trifluoromethanesulfonate ([Bmim]TfO), 1-butyl-1-methylpyrrolidinium trifluoromethanesulfonate ([Bmpyr]TfO) or tetr... |

The synthesis of 3,5,6,7-tetrasubstituted isoxazolo[4,5-b]pyridines and an evaluation of their in vitro antiproliferative activity.
Adv. Clin. Exp. Med. 21(5) , 563-71, (2012) Derivatives of isoxazolopyridines exhibit diverse biological activity. One method of synthesizing isoxazolo[4,5-b]pyridines is Friedlander condensation.To establish the conditions necessary for conventional and microwave synthesis of new 3,5,6,7-tetrasubstitu... |

Chemoselective synthesis of substituted pyrazoles through AgOTf-catalyzed cascade propargylic substitution-cyclization-aromatization.
Org. Biomol. Chem. 11(2) , 294-8, (2013) A cascade AgOTf-catalyzed chemoselective approach to 3,5/1,3-disubstitued pyrazoles from propargylic alcohols and para-tolylsulfonohydrazide has been developed. Good chemoselectivity is observed depending on the different substituents in the alkyne moiety of ... |
