Abstract:
1 Ectoparasitic insect pest controllers for animals, containing hydrazine derivatives of the general formula (I) as the active ingredient, and methods for application of the same: (I) nullwherein A is (II), (III), (IV), (V) (wherein R4 and R5 are each H, C1-6alkyl, or the like; and X is H, or one to five substituents selected from among halogeno and optionally halogenated C1-6alkyl groups); R1 is H or C1-6alkyl; R2 and R3 are each H, OH, C1-6alkyl, phenylcarbonyl, or the like; Y is H, or one to five substituents selected from among halogeno, nitro, and cyano; Z is halogeno, cyano, C1-6alkyl, or the like; and W is O or Snull. The insect pest controllers exert remarkable controlling effects on parasitic insect pests harmful to domestic or pet animals, e.g. fleas, lice, ticks.
Abstract:
Halogenated derivatives of two synthetic anti-tuberculosis agents, thioacetazone and p-aminosalicylic acid, have been synthesized. In general, the halogenated compound has the structure of Structure I: 1 wherein X1 is a halogen and X2 is a second halogen or hydrogen, and Y is sulfur or oxygen; or, has the structure of Structure IV: 2 wherein X1 is a halogen and X2 is a second halogen or hydrogen. Alternatively, the halogenated compounds may be pharmaceutically acceptable salts of these compounds. These halogenated derivatives possess anti-mycobacterial activity and are particularly useful for the treatment of Mycobacterium tuberculosis infections. In particular, fluorinated analogs of thioacetazone and p-amino-salicylic acid have been synthesized for use as anti-tuberculosis therapeutic agents either alone or in combination with other conventional anti-tuberculosis therapeutic agents.
Abstract:
A compound of the formula (I): wherein: for example, a compound below: wherein: R1 is CH3, H or Na; and X1—X2—X3 is: or its salt or a hydrate thereof is useful as PGD2 antagonist and can be used as a drug for treating diseases in which mast cell dysfunction is involved, for example, systemic mastocytosis and disorder of systemic mast cell activation, and also tracheal contraction, asthma, allergic rhinitis, allergic conjunctivitis, urticaria, injury due to ischemic reperfusion, and as an anti-inflammatory agent. It is particularly useful in the treatment of nasal occlusion.
Abstract:
