title: A powerful inhibitor of guanine deaminase.
abstract: The synthesis of 9-(p-carbetoxyphenyl) guanine is reported. The assays carried out on guanine deaminase from rat and rabbit liver and pig brain show that this compound is a powerful inhibitor. The compound has a Ki = 5 micronM for the enzyme from pig brain. The use of the inhibitor for the synthesis of a specific adsorbent for guanine deaminase was studied.
