  • Publication number: 20040093165
    Abstract: A system and method for generating a mask layout file to eliminate antenna effects in an integrated circuit are disclosed. The method includes analyzing a pattern in a mask layout file to identify a region including an antenna ratio less than a first design rule. A feature located in the identified region is moved based on a second design rule from a first position to a second position in the mask layout file. A grounding feature is placed in the space and automatically connected to a gate feature in the mask layout file such that the antenna ratio is increased to greater than or approximately equal to the first design rule.

  • Publication number: 20030032779
    Abstract: The present invention is directed to crystals comprising at least part of the estrogen receptor &agr; (ER&agr;) ligand binding domain, optionally bound to a ligand. The present invention is also directed to ligands that bind to ER receptors, and method of designing them. The present invention is also directed to a homology model of the ER&bgr; receptor.

  • Patent number: 6465687
    Abstract: Novel thyroid receptor ligands are provided which have the general formula (I) where R1 is alkyl of 1 to 4 carbons or cycloalkyl of 3 to 7 carbons; R2 and R3 are the same or different and are hydrogen, halogen, alkyl of 1 to 3 carbons or cycloalkyl of 3 to 5 carbons, at least one of R2 and R3 being other than hydrogen; n is an integer from 0 to 4; R4 is an aliphatic hydrocarbon, an aromatic hydrocarbon, carboxylic acid ester thereof, alkenyl carboxylic acid or ester thereof, hydroxy, halogen, cyano, or a phosphonic acid or an ester thereof, or a pharmaceutically acceptible salt thereof. A method for treating diseases associated with metabolism dysfunction or which are dependent on the expression of a T3 regulated gene, such as obesity, hypercholesterolemia, osteoporosis, hypothyroidism, and goiter, is also provided.
