Compounds of formula (I) described herein are inhibitors of the phosphodiesterase 4 (PDE4) enzyme and are useful for the prevention and/or treatment of an allergic disease state or a disease of the respiratory tract characterized by airway obstruction.
The design, synthesis, and characterization of synthetic anion membrane transporters are presented. These novel compounds impart ion permeability to phospholipid bilayers and also modulate cellular volume in mammalian cells in vitro. The compounds insert rapidly into liposomes and planar lipid bilayers.

A group of amino substituted benzoyl derivatives, their preparation and their use. The screening and research on an antiviral drug with hA3G/Vif as a target point proves that the 3-amino benzoyl derivatives not only have the combined activity for the hA3G/Vif, but also have a function of inhibiting replication of viruses. The present invention provides the possible breakthrough progress for the problem of HIV drug resistance, thereby providing a novel clinical antiviral drug which has higher efficiency.

represents cyano, nitro or the like, and the other represents a hydrogen atom or the like);
either R
1
or R
2
represents a group: -D-(X)m-R
6
or the like, and the other represents a group: -E-(Y)n-R
7
, hydrogen atom, aryl or the like;
R
3
is a hydrogen atom or the like; D and E independently represent aryl; X and Y independently represent O or the like;
R
