Abstract
Background:
Although Antiepileptic Drugs (AEDs) acting on various targets have been
applied in the clinic, the efficacy and tolerance of AEDs in the treatment of epilepsy have not
significantly improved. Therefore, there is an urgent need to develop some novel chemical moieties
with a better safety profile and greater efficacy. We designed and synthesized twenty-seven 4-
phenylpiperidin-2-one derivatives. This study aimed to investigate the potential use of a series of 4-
phenylpiperidin-2-one derivatives as anticonvulsant drugs.
Methods:
Two experimental methods, Maximal Electroshock (MES) and subcutaneous
pentylenetetrazole (scPTZ), were used to evaluate the anticonvulsant activity of the target
compounds. Moreover, neurotoxicity (NT) was tested using the rotarod test.
Results:
Compound 7-[4-(trifluoromethyl)phenyl]-6,7-dihydrothieno[3,2-b]pyridin-5-(4H)-one (11;
MES, ED50 = 23.7 mg/kg, PI > 33.7; PTZ, ED50 = 78.1 mg/kg, PI > 10.0) showed the best
anticonvulsant activity. The results of in vivo γ-aminobutyric Acid (GABA) estimation showed that
compound 11 may have an effect on the GABA system. Compound 11 showed significant
interactions with residues at the benzodiazepine (BZD)-binding site on GABAA receptors. Most
target compounds have favorable blood brain barrier (BBB) permeability and oral bioavailability in
predictions using silico molecular properties.
Conclusion:
According to the in vivo and in silico studies, compound 11 stand out as potential
anticonvulsant agents for further studies.

Abstract
Biospeciation of essential and toxic metal ions, metal complexes with biological or
medicinal activity are discussed in the paper in order to emphasize the importance of the distribution
of metal ions in biological milieu. The exact knowledge of the chemical species present
in the different organs/compartments/fluids/cells may provide essential information about
the pharmacokinetic properties and the biological effect of the metal ion or the drug candidate
metal complex. The transport of essential and toxic metal ions in the blood serum is discussed
first, which is followed by the description of biodistribution of several important metal complexes
with medicinal interest such as (i) anticancer, (ii) insulin-enhancing and (iii) MRI contrast
agents in biological fluids.
