<p>Tert-butyl pyridine-3-carboxylate is a synthetic precursor to the anti-HIV drug, 3,4-dihydro-2(1H)-quinolinone. It is an activated molecule that can be used in organic synthesis as an amide or ester activator for the formation of amides and esters from carboxylic acids. Tert-butyl pyridine-3-carboxylate binds to the e3 ubiquitin ligase, which prevents its ability to interact with other proteins such as HIV protease. This drug also has a proton at the methyl nicotinate nitrogen atom, which may contribute to its activity against HIV.</p>

<p>Octane-1-sulfonamide (OSA) is a glycol ether that is used as a reagent for biological samples. It reacts with the hydroxyl group on proteins, which causes the compounds to become more hydrophobic and interact with each other. The OSAs are also reactive with fatty acids, which leads to cross-linking of cell membranes. This interaction may be related to the low light activity of OSA. Octane-1-sulfonamide can also bind cationic polymers, which may be useful in ophthalmic drugs.</p>
