The invention deals with the derivatives of benzilidine having basic formula as follows (I): ##STR1## wherein X can be cyclohexanone, cyclopentanone, or acetone, while Y and Z can be either electron withdrawing, electron donating or steric group. Y may or may not be the same with Z. Methyl, ethyl, methoxy group or halogen were prefered in the experiment. The benzilidine cyclohexanone, benzilidine cyclopentanone, and benzilidine acetone derivates were found to be novel compounds showing anti-bacterial, antioxidant, and anti-inflammatory activities that enable them to be used for drug.
Benzylidene cyclohexanone, cyclopentanone and acteone derivatives and therapeutic methods of using same are disclosed. The compounds are non-toxic and exhibit potent anti-inflammatory, antibacterial and antioxidation activity. Also, certain compounds of the invention inhibit glutathione S-transferase ("GST"), but do not irritate the gastrointestinal tract. Pharmaceutical compositions containing the compounds of the invention and pharmaceutically acceptable carriers are also disclosed.
Described herein are compounds of formula I ##STR1## wherein M.sup.1, M.sup.2 and M.sup.3 have the meanings recited in the disclosure, liquid crystalline mixtures and polymers containing them, and the use of the compounds of formula I, the liquid crystalline mixtures and the polymers containing them in optical and electrooptical devices like liquid crystal displays or projection systems, patterned films and optical elements like polarizers, retardation films, compensators, color filters, holographic elements or polarization beam splitters, for photoswitching, in anisotropic membranes for the permeation of gases or fluids, adhesives, synthetic resins with anisotropic mechanical properties, cosmetic or pharmaceutical compositions, UV absorbers and sunscreens, diagnostics or liquid crystal pigments, for decorative and security applications, in nonlinear optics, optical information storage or as dopants.
