The present invention relates to a compound of Formula I:

##STR00001##

or a pharmaceutically acceptable salt thereof, wherein the symbols are as defined in the specification; a pharmaceutical composition comprising the same; and a method for treating or preventing autoimmunity disease using the same.

Provided is a prodrug of 2-nitro-1-imidazolepropionic acid and a therapeutically active organic compound having on the molecule an amino group, a cyclic amino group or a hydroxyl group, particularly a prodrug in which the therapeutically active organic compound is selected from among antitumor agents. The prodrug cleaves specifically under hypoxic conditions in vivo to exhibit the inherent therapeutic activity.

The present disclosure generally provides compounds useful for treating cancer. In some aspects, the disclosure provides small-molecule cytotoxins that are chemically modified to include one or more moieties that include hydrophobic portions. In some embodiments, the disclosure provides small-molecule cytotoxins that are chemically modified with fatty acid-containing moieties. In some aspects, the disclosure provides compositions, such as pharmaceutical compositions, that include such modified small-molecule cytotoxins and a protein. In some embodiments, the protein is albumin or an albumin mimetic. Further, the disclosure provides various uses of these compounds and compositions.
