The synthesis of a large group of benzenesulfonamides containing both a primary and secondary sulfonamide moiety is described. These compounds are powerful inhibitors of several isozymes of the enzyme carbonic anhydrase. Separate QSAR's are given for inhibition of three of these isozymes, using descriptors mainly derived from molecular orbital calculations by the semiempirical AM1 method. Activity was found to depend on electrostatic potential-based charges on the atoms of both sulfonamide groups, HOMO and LUMO energies, dipole moments, and lipophilicities. These results are compared with those from other studies. (C) Elsevier, Paris.
yielded a series of biphenyl urea compounds. These were chemically optimized to a new structural class of potentantimalarialagents. The compounds did not inhibit plasmodium LDH enough to fully explain their potency. Therefore we conclude that an unknown mode of action may be the cause of the antimalarial activity.
