Compounds of the general formula
wherein:
X is halogen or trifluoromethyl;
R, is hydrogen, halogen or trifluoromethyi;
R2 is hydrogen, methyl or hydroxymethyl;
R3 is hydrogen or lower alkyl; and
Y is methylene, methylene substituted with a lower alkyl or hydroxyl group, sulfinyl, sulfonyl, oxygen or sulfur, exhibit a cerebral protective effect and are applicable to the treatment of cerebral ischaemia and cerebral hypoxia.
The compounds may be made by acylating a suitable piperidine or morpholine with the appropriate cinnamoyl chloride, and if necessary oxidizing the reaction product.

exerted superior or comparable activity to all the reference drugs. In the celldivision inhibitory activity, all the compounds showed the same trend as their in vitro antibacterial activity, exhibiting better activity against S. aureus ATCC25923 than the other strains. Additionally, compounds 3, 6, 7 and 8 displayed potent celldivision inhibitory activity with an MIC value of below 1 μg/mL, over 256-fold
