Quantitative structure-activity relationships in dihydropteroate synthase inhibition by multisubstituted sulfones. Design and synthesis of some new derivatives with improved potency
摘要:
On the bases of the linear correlation existing for a training set of homomultisubstituted 4-aminodiphenyl sulfones between the computed (INDO) electronic net charges of the SO2 group and the enzymic inhibition data on dihydropteroate synthase from Escherichia coli, seven new heteromultisubstituted derivatives were designed, synthesized, and tested for their inhibition potencies. These compounds were found to be from 5-11 times more effective than 4,4'-diaminodiphenyl sulfone. The implications of the results in the drug design and in the model for the enzyme-inhibitors interaction are discussed.

Some 4-mercaptophenols and naphthalenols are prepared by reaction of sulfur chloride and the corresponding phenol or naphthalenol, followed by reduction in mineral acid in the presence of zinc metal.
