(2-one-1,3-dioxolan-4-yl) methyl 3-mercaptopropanoate(DMMP), which can be used for Michael addition reaction, was synthesized through two simple routs. First, glycerol carbonate was synthesized under mild conditions without any solvent, using glycerol and dimethyl carbonate as raw materials by green chemistry way. Then DMMP was obtained by simple esterification reaction of glycerol carbonate and 3-mercaptopropionic acid. The structure of them was characterized by 1H NMR and FTIR.

SummaryPlasminogen activator was isolated from disrupted pig leucocytes by the aid of DEAE chromatography, gel filtration on Sephadex G-100 and final purification on CM cellulose, or by preparative gel electrophoresis.Isolated plasminogen activator corresponds No. 3 band of the starting sample of leucocyte cells (that is composed from 10 gel electrophoretic bands).pH optimum was found to be in pH range 8.0–8.5 and the highest pH stability is between pH range 5.0–8.0.Inhibition studies of isolated plasminogen activator were performed with EACA, AMCHA, PAMBA and Trasylol, using Anson and Astrup method. By Astrup method 100% inhibition was found with EACA and Trasylol and 30% with AMCHA. PAMBA gave 60% inhibition already at concentration 10–3 M/ml. Molecular weight of plasminogen activator was determined by gel filtration on Sephadex G-100. The value obtained from 4 different samples was found to be 28000–30500.
