demonstrated moderate to high affinity for 5-HT1A and alpha1 receptorbinding sites but had no affinity for D2 receptors. The study of the length of the alkyl chain and the imide substructure has allowed us to suggest some differences between the 5-HT1A and the alpha1-adrenergic receptors: (i) for III and IV, affinity for the 5-HT1A receptor as a function of the length of the methylene linker decreases
The present study aimed to design and synthesize a new series of hybrid compounds with pyrrolidine-2,5-dione and thiophene rings in the structure as potential anticonvulsant and antinociceptive agents. For this purpose, we obtained a series of new compounds and evaluated their anticonvulsantactivity in animal models of epilepsy (maximal electroshock (MES), psychomotor (6 Hz), and subcutaneous pentylenetetrazole

through which epilepsy can be effectively controlled. Therefore, in the present studies, a series of sixteen new 1-[(4-arylpiperazin-1-yl)-propyl]-3-methyl-3-phenyl- and 3-ethyl-3-methylpyrrolidine-2,5-dione derivatives as potential anticonvulsant agents was synthesized. METHODS Anticonvulsant properties were evaluated in the maximal electroshock (MES), subcutaneous pentylenetetrazole (scPTZ) and psychomotor

The present invention utilizes three families of bacterial enzymes, which play a key role in mycothiol biosynthesis. The three families are bacterial cysteine:glucosaminyl inositol ligases (MshC) with catalytic ligase activity for ligation of glucosaminyl inositol and cysteine, bacterial acetyl-CoA:Cys-GlcN-Ins acetyltransferases (MshD) with catalytic activity for addition of an acetyl group to Cys-GlcN-Ins and bacterial MshA glycosyltransferase with catalytic activity for production of GlcNAc-Ins. The invention provides methods for using the mycothiol biosynthesis ligases, acetyltransferases or glycosyltransferases in drug screening assays to determine compounds that inhibit activity. The invention also provides inhibitors of the production or activity of the enzymes of mycothiol biosynthesis, and use of the inhibitors for treating microbial infection.

multi-target ligand of G-protein-coupled receptors (GPCRs), in particular D2, 5-HT1A, and 5-HT2Areceptors. Such receptor profile may be beneficial for the treatment of schizophrenia. Compounds 1–16 were designed, synthesised, and subjected to further evaluation. Their affinities for the above-mentioned receptors were assessed in radioligandbindingassays and efficacy towards them in functional assays. Compounds
