To discover promising sulfated allosteric modulators ( SAMs ) of glycosaminoglycan - binding proteins ( GBPs ) , such as human factor XIa ( FXIa ) , we screened a library of 26 synthetic , sulfated quinazolin - 4 ( 3H ) - ones ( QAOs ) resulting in the identification of six molecules that reduced the Vmax of substrate hydrolysis without influencing the KM .
 Chemical: sulfated quinazolin - 4 ( 3H ) - ones; Chemical: QAOs
