RESUMEN

Objective To prepare the immunoconjugate composed of Adriamycin nanoparticles and VEGFR 2 monoclonal antibody(conjugate of ADM-NP and VEGFR 2-MAb) and study its pharmacokinetics property. Methods Adriamycin nanoparticles were prepared by using double emulsion method, with PLA and O-CMC as materials. Conjugate of ADM-NP and VEGFR 2-MAb was prepared by using molecule conjugate technology. Immunoreactivity of the conjugate with type IV collagenase and H 22 cell were analyzed by using ELISA. Pharmacokinetics parameters of the immunoconjugate were obtained by using SD rats as study objects. Results The prepared ADM-NP was sphere particles under SEM, which diameters were (160±34) nm. The drug loading rate and entrapment rate were (30.15±3.5)% and (80.56±4.24)% respectively. Conjugate of ADM-NP and VEGFR 2-MAb was successfully prepared, which had immunoreactivity with type IV collagenase and H 22 cell. The immunoconjugate showed good ADM control-release ability and could prolong the retention time of ADM in vivo. Conclusion Conjugate of ADM-NP and VEGFR 2-MAb keeps the immunoreactivity of VEGFR 2-MAb and shows good ADM control-release ability.
