Iodoacetamide (IA, IAM, 2-Iodoacetamide) is an alkylating agent that is commonly used for alkylation of cysteine during sample preparation for proteomics.
A multiple cleavage cascade mechanism is partially utilized to produce virus structural proteins. In infected cells, the largest viral induced protein obtained has a molecular weight of 144,000. Pretreatment of the infected cells with iodoacetamide before pulsing with 35S-methionine results in the appearance of two polypeptides of molecular weights 205,000 and 190,000. Other changes occur in viral protein precursors in the presence of iodoacetamide.[2]
Iodoacetamide induces a concentration-dependent weight loss and reduces water intake in both species (Wistar rats and CD1, C57Bl/6J mice). Iodoacetamide induces gastritis in rats.[3]

Determination of lomefloxacin, an antibacterial drug, in pharmaceutical preparations based on its polarographic catalytic wave in the presence of 2-Iodoacetamide
Anal Sci 2001 Oct;17(10):1145-8.PMID:11990585DOI:10.2116/analsci.17.1145.
In a 0.125 mol/L phosphate (pH 6.6)/2.5 x 10(-4) mol/L 2-Iodoacetamide solution, lomefloxacin yields a response of a polarographic catalytic current. The second-order derivative peak current of the catalytic wave of lomefloxacin is proportional to its concentration in the range of 1.0 x 10(-8)-1.0 x 10(-6) mol/L (r = 0.998). The sensitivity of the catalytic wave is 25-times higher than that of the corresponding reduction wave for 5.0 x 10(-7) mol/L lomefloxacin. The proposed method was applied to the determination of lomefloxacin in pharmaceutical preparations. The polarographic reduction wave is ascribed to a one-electron reduction of the C=C bond of lomefloxacin zwitterion accompanied by an acid-base equilibrium. The catalytic wave should be caused by regeneration of the lomefloxacin molecule at electrode surface due to the one-electron reduction product being further oxidized by electroreductive intermediate products of 2-Iodoacetamide.
