Biological Activity

[Description]:

Caracemide (NSC-253272) is a novel anticancer agent derived from a hydroxamic acid. Caracemide inactivates R1 by covalent modification at the substrate-binding site and inhibits the enzyme ribonucleotide reductase of Escherichia coli. Caracemide has demonstrated to produce severe central nervous system (CNS) toxicity. Caracemide has a toxic metabolite, methylisocyanate (MIC), in vivo[1][2].

[In Vivo]

The mercapturic acid derivative AMCC was identified in urine rats following administration to rats of a single i.p. dose (6.6 mg/kg) of caracemide (NSC-253272)[1]. .
