Research Papers : Drug Release Behaviors and Antitumor Effects of The Biodegradable Mcrogel Microspheres

Kong Soo Kim

Abstract

Biodegradable microsphere containing Bovine Serum Albumin (BSA) or 5-fluorouracil (5-FU) was prepared with the microgel based on poly(caprolactone diol) by a modified solvent evaporation method. The effects of the crosslinking degree of microgel, pH, the concentration of BSA and 5-FU of medium on the release properties were investigated in vitro. Drug release rate from the micorsphere containing BSA was relatively rapid than the microsphere containing 5-FU. Antitumor activities were tested against Sarcoma-180 asites in vivo. The rate of medium survival of treated mice to that of control mice was depend on injected amount of the microsphere containing 5-FU.

초록

폴리카프로락톤을 기초로 하여 용액증합방법으로 microgel을 합성하고, 용매증발법으로 모델 약물인 BSA와 5-fluorouracil (5-FU)이 담지된 microsphere를 제조하였다. Microgel을 제조함에 있어 가교제의 양과 pH 및 BSA와 5-FU의 담지량에 따른 약물의 방출속도를 in vitro 실험한 결과, BSA를 함유하는 microsphere가 5-FU를 함유하는 경우 보다 약물이 훨씬 빨라 방출되었다. 또한, 5-FU를 담지한 microsphere를 saecoma-180 asites 종양세포가 이식된 마우스에 투여하여 실험한 결과, 투여량에 따라 암종양세포에 대하여 현저한 연명효과를 나타내었다.
