elimination, acetate decomposition as well as oxidative degradation of the Schiff base moiety. The bioevaluation of compounds in relation to planktonic and biofilm-embedded microbial cells, as well as to human cells, indicates an improved activity of complexes over ligands. The same tendency was observed for antioxidant activity.
A series of several new isoniazid derivatives, isonicotinic acid 2-(2-hydroxy-8-substituted-tricyclo[7.3.1.02.7]tridec-13-ylidene)-hydrazides, were synthesized and fully characterized. These new isoniazid derivatives were studied regarding their antibacterial activity and cytotoxicity, as well as their influences on some metabolizing enzymes. The best anti-mycobacterial activity was observed in the

Dehydration of 2-hydroxy-8-R-tricyclo[7.3.1.0(2.7)]tridecan-13-ones (R = H, Me, Ph) effected by various reagents provided 8-R-tricyclo[7.3.1.0(2.7)] tridecen-13-ones with different positions of the double bond. In the presence of phosphoric acid arise isomers with the double bond in 2(3) position, a mixture of hydrochloric and acetic acid primarily affords isomers with the double bond in 2(7) position that further migrates into 7(8) position at R = Me, Ph.
