The first Z-stereoselective method was developed for the synthesis of unsaturated acids containing a 1Z,5Z,9Z-triene moiety in 61–64% yields using the new Ti-catalyzed cross-coupling of oxygen-containing and aliphatic 1,2-dienes as the key synthetic step. It was shown for the first time that trienoic acids with non-methylene-interrupted Z-double bonds show moderate cytotoxic activities against tumor cell lines (Jurkat, K562, U937, HL60, HeLa), human embryonic kidney cells (Hek293), normal fibroblasts and human topoisomerase I (hTop1) inhibitory activity in vitro. The synthesized acids efficiently initiate apoptosis of Jurkat tumor cells, with the cell death mechanism being activated by the mitochondrial pathway. A probable mechanism of topoisomerase I inhibition was also hypothesized on the basis of in silico studies resorting to docking. The activation and inhibition of the most versatile intracellular signaling pathways (CREB, JNK, NFkB, p38, ERK1/2, Akt, p70S6K, STAT3 and STAT5 tyrosine kinases) responsible for cell proliferation and for initiation of apoptosis were studied by multiplex assay technology (Luminex xMAP).

Compounds for treating abuse of nicotinic receptor agonists, addiction to psychostimulant drugs, addiction to opiates, addiction to alcohol, addiction to tobacco products, addiction to nicotine, schizophrenia and related diseases, depression and related conditions, Alzheimer's disease, Parkinson's disease, irritable bowel syndrome, and colitis. The compounds competitively inhibit central nervous system acting nicotinic receptor agonists and act at the putative α3β2* and α4β2 neuronal nicotinic receptors in the central nervous system.

Three pheromones, (6Z,11Z)-hexadeca-6,11-dien-1-yl acetate (from Eudia pavonia), (5Z,9Z)-heptacosa-5,9-diene (from Drosophila melanogaster) and gossyplure, have been synthesized each by two consecutive consequences of nickel-assisted Grignard reactions with cyclic enol ethers and preparation of Grignard reagents from the resultant alcohols.
