The functional groups proposed for the [[pharmacophore]] of the DKAs includes a aromatic ring located a certain distance from hydrogen bond donating and accepting groups. | The functional groups proposed for the [[pharmacophore]] of the DKAs includes a aromatic ring located a certain distance from a group of hydrogen bond donating and accepting groups. The orientation of a hydrogen bond donor group relative to 2 required hydrogen bond acceptors is very important for activity. | ||

The structure to the right is the first HIV integrase inhibitor approved in the US, raltegravir (Isentress). Compare its structure to that of the prototype DKA shown above. Can you see a hydrophobic group at one end of the molecule, with hydrogen bond donor, acceptor, and donor functional groups next to each other? | |||
