  • Publication number: 20060070135
    Abstract: The present invention provides mice that have had their PTP-1B genes disrupted by targeted homologous recombination. The mice have no detectable PTP-1B protein, yet appear to be physiologically normal. However, in the fed state on a normal diet, the mice have half the level of circulating insulin as their wild-type littermates. In glucose and insulin tolerance tests, the mice show an increased insulin sensitivity. When fed a high fat, high carbohydrate diet, the mice show a resistance to weight gain as compared to their wild-type littermates. Methods of making the mice and cell lines derived from the mice are also provided. The present invention also provides methods of identifying inhibitors of the enzymatic activity of PTP-1B as well as inhibitors identified by such methods.

  • Publication number: 20060009500
    Abstract: This invention is directed to methods of using compounds having the structure: and including stereoisomers, solvates, and pharmaceutically acceptable salts thereof, wherein each of R1, R2, R3 and R4 is independently selected from hydrogen, R5, R6, and R7; R5 is selected from alkyl, heteroalkyl, aryl and heteroaryl; R6 is selected from (R5)n-alkylene, (R5)n-heteroalkylene, (R5)n-arylene and (R5)n-heteroarylene; R7 is selected from (R6)n-alkylene, (R6)n-heteroalkylene, (R6)n-arylene, and (R6)n-heteroarylene; and n is selected from 0, 1, 2, 3, 4 and 5, where R1 and R2 may together form a heterocyclic structure including the nitrogen to which they are both attached, and R3 and R4 may together form a heterocyclic structure including the nitrogen to which they are both attached; and each of L1 and L2 is independently selected from -A1-A2-A3- where each of A1, A2, and A3 is independently selected from a direct bond, alkylene, heteroalkylene, arylene and heteroarylene.
