- Discovery of Potent and Selective Inhibitors of Ataxia Telangiectasia Mutated and Rad3 Related (ATR) Protein Kinase as Potential Anticancer Agents
-
DNA-damaging agents are among the most frequently used anticancer drugs. However, they provide only modest benefit in most cancers. This may be attributed to a genome maintenance network, the DNA damage response (DDR), that recognizes and repairs damaged DNA. ATR is a major regulator of the DDR and an attractive anticancer target. Herein, we describe the discovery of a series of aminopyrazines with potent and selective ATR inhibition. Compound 45 inhibits ATR with a Ki of 6 nM, shows >600-fold selectivity over related kinases ATM or DNA-PK, and blocks ATR signaling in cells with an IC50 of 0.42 μM. Using this compound, we show that ATR inhibition markedly enhances death induced by DNA-damaging agents in certain cancers but not normal cells. This differential response between cancer and normal cells highlights the great potential for ATR inhibition as a novel mechanism to dramatically increase the efficacy of many established drugs and ionizing radiation.

- OXAZOLE DERIVATIVES AS HISTAMINE H3 RECEPTOR AGENTS, PREPARATION AND THERAPEUTIC USES
-
The present invention discloses novel aryl oxazole compounds of Formula I (I), or pharmaceutically acceptable salts thereof, which have histamine-H3 receptor antagonist or inverse agonist activity, as well as methods for preparing and using such compounds. In another embodiment, the invention discloses pharmaceutical compositions comprising compounds of Formula I as well as methods of using these compositions to treat obesity, cognitive deficiencies, narcolepsy, and other histamine H3 receptor-related diseases. Formula I (I) or a pharmaceutically acceptable salt thereof, wherein: m is independenlly at each occurrence 1, 2, or 3, Z independently represents carbon (substituted with hydrogen or the optional substituents indicated herein) or nitrogen, provided that when Z is nitrogen then R6 is not attached to Z; R1 and R2 are independently -(C1-C7) alkyl(optionally substituted with one to three halogens), or R1 and R2 and the nitrogen to which they are attached form an azetidinyl ring, a pyrrolidinyl ring, or a piperidinyl ring, wherein further the azetidinyl, pyrrolidinyl, or piperidinyl ring so formed may be optionally substituted one to three times with R5; R6 is independently at each occurrence -H, -halogen, or -CH3.
