| The best substrates for all preparations are 1,4-diaminobutane (putrescine) and 1,5-diaminopentane (cadaverine), which in nature are produced along with histamine and other biogenic amines in protein hydrolysis during putrefaction of tissues both in living and dead organisms. In a first step, the enzyme is reacted in an organic solvent with a bifunctional monomer such as p-phenylene diisocyanate, 4-methyl-m-phenylene diisocyanate or 4,4'-methylenebisphenyl diisocyanate, and in a second step a bifunctional amine such as N-phenylethylenediamine, 1,6-diaminohexane, N,N'-diethyl-ethylenediamine or 1,4-diaminobutane is added. T4T-dimethyl T4T-dimethyl was synthesized and purified according to route II for T2T-dimethyl as previously described [8], except that 1,2-diaminoethane was replaced by 1,4-diaminobutane. |
