  • Publication number: 20230106592
    Abstract: Described herein are methods of treating a proliferative disorder (e.g., cancer) in a patient by administering a DNA damaging agent and between about 12 and about 48 hours later administering to the subject a compound that inhibits ATR protein kinase. Methods of treating a proliferative disorder (e.g., cancer) in a patient by administering a compound that inhibits ATR protein kinase are also described. Exemplary ATR inhibitors are represented by Formulae A-I and A-II: or a pharmaceutically acceptable salt thereof, wherein the variables are as defined herein.

  • Publication number: 20070149577
    Abstract: The invention provides for compounds having the structure according to the formula I wherein: X is a carbon or nitrogen atom; Ar is phenyl or heteroaromatic ring; R1 is hydrogen, halogen, CN or (1C-4C)alkyl; R2 is hydrogen, halogen or optionally fluorinated (1C-3C)alkoxy; R3 and R5 are independently hydrogen, optionally halogenated (1C-4C)alkyl, optionally halogenated (1C-4C)alkoxy, optionally halogenated aryl(1C-4C)alkoxy, optionally halogenated (1C-4C)alkenyl or hydroxylmethyl; R4 is hydrogen, halogen, optionally halogenated (1C-4C)alkoxy or optionally halogenated aryl(1C-4C)alkoxy; R6 is hydrogen, benzyl, optionally substituted with one or more halogens or (1C-4C)alkyl, or R6 is optionally halogenated (1C-4C)alkyl; each R7 independently is hydrogen, halogen, optionally halogenated (1C-4C)alkyl or optionally halogenated (1C-4C)alkoxy and pharmaceutically suitable acid addition salts thereof for use as glucocorticoid receptor modulators, in particular for treatment of central nervous system disorders.

  • Publication number: 20050190507
    Abstract: A magnetic field sensing structure is described that uses magnetoresistance as a signal. The structure includes an inhomogeneous network of interconnected semiconducting elements which may be of various shapes. By tuning or selecting physical properties of the elements, the overall magnetoresistive response may be adjusted to be large and substantially linear over a range of magnetic fields. Such sensing structures may be used, for example, in hard-disk read-heads. Other embodiments may find application in low or high field sensing, with some being of particular interest where thermal stability is of importance.
