New modifications on the C-8 4-aminobenzyl unit of the previously reported 3-alkyl-1,8-dibenzylxanthine inhibitors of cPEPCK are presented. The most active compound reported here is the 5-chloro-1,3-dimethyl-1H-pyrazole-4-sulfonic acid amide derivative 2 with an IC{sub 50} of 0.29 {+-} 0.08 {mu}M. An X-ray analysis of a heteroaromatic sulfonamide is presented showing a new {pi}-{pi} interaction. |
