    摘要： The present invention features rifamycin analogs that can be used as therapeutics for treating or preventing a variety of microbial infections. In one form, the analogs are acetylated at the 25-position, as is rifamycin. In another form, the analogs are deacetylated at the 25-position. In yet other forms, benzoxazinorifamycin, benzthiazinorifamycin, and benzdiazinorifamycin analogs are derivatized at various positions of the benzene ring, including 3′-hydroxy analogs, 4′- and/or 6′ halo and/or alkoxy analogs, and various 5′ substituents that incorporate a cyclic amine moiety.

    摘要： The present invention provides a compound which has the effect of PDE 10A inhibition, and which is useful as a medicament for preventing or treating schizophrenia or so on. A compound represented by the formula (1′): wherein, Ring A′ represents an optionally substituted pyridine ring, an optionally substituted pyridazine ring, a pyrimidine ring, or 10 a pyrazine ring, R1′ represents (1) wherein, R1a′ represents an optionally substituted phenyl group, or an optionally substituted 5- to 10-membered heterocyclic group, Ring B2 represents a bond, —S—, -0-, —CO—, an optionally substituted methylene group, or —NRa′— (Ra′ represents a hydrogen atom, or an optionally substituted C1-6 alkyl group), and Ring B1′ represents an optionally further substituted 6- to 10-membered aromatic hydrocarbon ring, or an optionally further substituted 5- to 10-membered aromatic heterocyclic ring, or alternatively, L′ and R1a′ may be taken together to form an optionally substituted bicyclic or tricyclic fused heterocyclic group, or (2), wherein, R1b′ represents an optionally substituted phenyl group, or an optionally substituted 5- to 10-membered heterocyclic group, Ring B2′ represents an optionally substituted benzene ring, an optionally substituted pyridine ring, an optionally substituted pyrimidine ring, an optionally substituted pyrazine ring, or an optionally substituted pyridazine ring, Ring D′ represents an optionally further substituted 5- or 6-membered ring, R2′ represents a hydrogen atom, or a substituent, X′ represents ═N— or ═CRb′—(Rb′ represents a hydrogen atom, or a substituent), - - - - - represents that Rb′ and R2′ may form, taken together with the carbon atom and the nitrogen atom to which they are each adjacent, an optionally substituted 5- to 7-membered ring when.X′ is ═CRb′, or a salt thereof.

    摘要： Imidazopyrazines of Formula I and pharmaceutically acceptable salts and mixtures thereof, are provided herein. Pharmaceutical compositions comprising at least one chemical entity and one or more pharmaceutically acceptable vehicle are also provided. Methods of treating patients suffering from certain diseases and disorders responsive to the inhibition of Syk activity, which comprises administering to such patients an amount of at least one chemical entity effective to reduce signs or symptoms of the disease or disorder are disclosed. These diseases include cancer (e.g., B-cell lymphoma and leukemia), autoimmune diseases, inflammatory diseases, acute inflammatory reactions, and allergic disorders. Methods of treatment include administering at least one chemical entity as a single active agent or administering at least one chemical entity in combination with one or more other therapeutic agents. Also provided are methods for determining the presence or absence of Syk kinase in a sample.
