putrescine

 [pu-tres´in]
a polyamine first found in decaying meat; small quantities occur in most cells.

pu·tres·cine

(pyū-tres'ēn),
1,4-Diaminobutane; a poisonous polyamine formed from the amino acid arginine during putrefaction; found in urine and feces; in certain cells, putrescine is a precursor to γ-aminobutyrate.
