4/03/2013В В· These findings indicate an overlapping structure activity relationship of inhibitors for ASBT and NTCP, with NTCP being a less permissive transporter than ASBT in terms of susceptibility to inhibition by FDA approved drugs. While many quantitative structure activity relationship analyses involve the interactions of a family of molecules with an enzyme or receptor binding site, QSAR can also be used to study the interactions between the structural domains of proteins.

Structure Activity Relationships (SAR) can be used to predict biological activity from molecular structure. This powerful technology is used in drug discovery to guide the acquisition or synthesis of desirable new compounds, as well as to further characterize existing molecules. The compounds exhibited a structure activity relationship (SAR) because the activity of compounds varies with substitution. The nitrogroup-containing compounds 56h , 56i ,and 56j showed higher activity than the chloro-group-( 56c and 56d ) or the bromo-group-containing compounds ( 56e and 56f ).
