An anomalous hydration/dehydration sequence for the mild generation of a nitrile oxide [PDF]

, 2011
A nitrile oxide containing a carbamoyl group is readily generated upon the treatment of 2-methyl-4-nitro-3-isoxazolin-5(2H)-one with water under mild reaction conditions, even in the absence of special reagents.

Polyfunctionality of broadly neutralizing HIV-1 antibodies

Current Opinion in HIV and AIDS, 2023
Purpose of review The discovery of broadly neutralizing HIV-1 antibodies (bNAbs) has provided a framework for vaccine design and created new hope toward an HIV-1 cure. These antibodies recognize the HIV-1 Envelope and inhibit viral fusion with unprecedented breadth and potency. Beyond their unique neutralization capacity, bNAbs

Identification and quantification of polyfunctionalized hopanoids by high temperature gas chromatography–mass spectrometry [PDF]

, 2012
Hopanoids are triterpenoids produced mainly by bacteria, are ubiquitous in the environment, and have many important applications as biological markers. A wide variety of related hopanoid structures exists, many of which are polyfunctionalized.
