Drug-Biomacromolecule Interaction (VI) Binding of Nalidixic Acid and Probenecid to Bovine Serum Albumin

약물과 생체고분자간의 상호작용(VI) Nalidixic Acid 및 Probenecid와 우혈청 단백간의 결합에 관한 연구

Binding of nalidixic acid which is used primarily in the treatment of urinary infection and probenecid which is used as a uricosuric agent to bovine serum albumin were studied using difference spectrophotomeric method. 2-(4'-Hydroxybenzeneazo) bcnzoic acid as a spectrophotometric probe was used for measuring the binding of nalidixic acid and probenecid to bovine serum albumin. The association constants of nalidixic acid and probenecid were $1.58{\times}10^{4}M^{-1}$ and $1.70{\times}10^{4}M^{-1}$, respectively.
