Novel peptidomimetics comprising N-amino cyclic urea residues are disclosed. Use of such peptidomimetics for modulating the activity of CD36 or IL-1 receptor in a cell, and for treating CD36- or IL-1-related disease, disorder or condition is also described
The first total synthesis of a molecule possessing the structure proposed for keramamide J is described, providing data indicating that the structure of this natural product should be re-examined.
