The aim of this presentation is to review some of our recent work mostly on poly(amidoamine)s (PAAs) and some other families of polymers structurally related to PAAs of medical interest. PAAs are obtained by stepwise polyaddition of primary monoamines, or bis secondary amines, to bisacrylamides. There are several other ter-amino polymers structurally related to PAAs, such poly(amido phosphine)s (PAPs), poly(ester-amine)s (PEAs), poly(ketone-amine)s (PKAs), poly(amidothioeteramine)s (PATAs) poly(esterthioether amine)s (PTEAs), and poly(sulphone thioetheramine)s (PSTAs). Most of the PAAs exhibit heparin complexing ability. PAAs are also being considered as soluble carriers for delivering anti-cancer drugs. Some of these polymers have been studied as antimicrobial agents. PAAs with different structures degrade at different rates under physiological conditions. The degradation rate is also strongly influenced by pH. The quaternarized PATAs and PTEAs are reasonably stable over a period of some days, but ultimately degrade to oligomeric products, while the quaternized PAAs do rapidly degrade.
