The synthesis of the biopolyurethane was based on the reaction of 4,4'-diphenylmethane diisocyanate prepolymer, pMDI (Rubinate 5005, Huntsman Polyurethanes, USA) with an equivalent weight of 131 g/eq and a hydroxylated soybean oil as the polyol component, Agrol 3.6 from Biobased Technologies, USA, with an OH value = 120.8 mg KOH/g (measured according to DIN 53240 norm).
Under normal oxygen tension, HIF-[alpha] is hydroxylated (OH) through an iron ([Fe.sup.2+]) dependent pathway to allow recognition by the von Hippel-Lindau (VHL) gene allowing ubiquitination (Ub) and proteosomal degradation.
