| 用途: | GSK837149A is the first selective inhibitor of human fatty acid synthase (FAS) known to act specifically and selectively on the KR activity of the enzyme. It was first isolated as a minor impurity in a sample found to be active against the enzyme in a high-throughput screening campaign. This compound and its analogs synthesized, all being symmetrical structures containing a bisulfonamide urea, act by inhibiting the beta-ketoacyl reductase activity of the enzyme. GSK837149A inhibits FAS in a reversible mode, with a Ki value of approximately 30 nm, and it possibly binds to the enzyme-ketoacyl-ACP complex. Although initial results suggest that cell penetration for these compounds is impaired, they still can be regarded as useful tools with which to probe and explore the beta-ketoacyl reductase active site in FAS, helping in the design of new inhibitors. |
