Novel Poly(L-lactide-co-ε-caprolactone) Matrices Obtained with the Use of Zr[Acac]4 as Nontoxic Initiator for Long-Term Release of Immunosuppressive Drugs
Figure 6
1H NMR spectra of CyA in CDCl3; matrix made of less random PLACL 75 : 25 with CyA (after 14 and 182 days of degradation); matrix made of less random PLACL 75 : 25 without drug. Assigned signals arise from cyclosporine A: NH (1) and N–CH3 (2); methine groups of lactidyl units (3) and OCH2 groups of caproyl unit of copolymer (4).
