摘要
Urease from the seeds of pigeonpea was competitively inhibited by boric acid, butylboronic acid, phenylboronic acid, and 4-bromophenylboronic acid; 4-bromophenylboronic acid being the strongest inhibitor, followed by boric acid. butylboronic acid. phenylboronic acid, respectively. Urease inhibition by boric acid is maximal at acidic pH (5.0) and minimal at alkaline pH (10.0), i.e., the trigonal planar B(OH)(3) form is a more effective inhibitor than the tetrahedral B(OH)(4)(-) anionic form. Similarly, the anionic form of phenylboronic acid was least inhibiting in nature.
