  respectively) were evaluated. Variations in each of these properties were analyzed depending on the substituents present on each compound. To relate the chemical structures of the synthesized compounds to their photophysical properties, Hansch analysis (2D-QSPR) was applied. As a result of Hansch analysis, we found different photophysical properties related to molecular orbitals and the energy of their derivatives

  A series of homoisoflavonoids [(E)-3-benzylidenechroman-4-ones la-w, 3-benzyl-4H-chromen-4-ones 2a-g, and 3-benzylchroman-4-ones 3a-e] have been synthesized and tested in vitro as inhibitors of human monoamine oxidase isoforms A and B (hMAO-A and hMAO-B). Most of the compounds were found to be potent and selective MAO-B inhibitors. In general, the (E)-3-benzylidenechroman-4-ones la-w showed activities in the nano- or micromolar range coupled with high selectivity against hMAO-B. The reduction of the exocyclic double bond results in compounds 3a-e selective against isoform B and active in the micromolar range. In contrast, the endocyclic migration of the double bond (compounds 2a-g) generally produces the loss of the inhibitory activity or a marked reduction in potency. (E)-3-(4-(Dimethylamino)benzylidene)chroman-4-one (1l) and (E)-5,7-dihydroxy-3-(4-hydroxybenzylidene)chroman-4-one (1h) were the most interesting compounds of the entire series of inhibitors, showing hMAO-B affinity better than the selective inhibitor selegiline. Molecular modeling studies have been carried out to explain the selectivity of the most active homoisoflavonoids 1h and 1l.

  A series of 3-benzylidene-4-chromanones 1a-1 were prepared and their cytotoxicity towards human Molt 4/C8 and CEM T-lymphocytes as well as murine L1210 lymphoid leukemia cells were compared to the previously generated biodata in these three assays for the isosteric 2-benzylidene- 1-tetralones 2a-1. Over 40% of the compounds in series 1 were more potent than their counterparts in series 2, while equipotency was noted in one-third of the comparisons made. In general the IC(50) values of 1a-1 towards the human T-lymphocytes were in the low micromolar range. Molecular modelling revealed differences in shapes of representative molecules in series 1 and 2 which may contribute to the variation in cytotoxic potencies. Most of the compounds in series 1 displayed greater potencies towards HSC-2, HSC-3, HSC-4 and HL-60 neoplasms than HGF, HPC, and HPLF normal cells and were well tolerated in mice.
