- Synthesis and structureactivity relationship of novel conformationally restricted analogues of serotonin as 5-HT6 receptor ligands
-
5-Hydroxytryptamine 6 receptors (5-HT6R) are being perceived as the possible target for treatment of cognitive disorders as well as obesity. The present article deals with the design, synthesis, in vitro binding and structureactivity relationship of a novel series of tetracyclic tryptamines with the rigidized N-arylsulphonyl, N-arylcarbonyl and N-benzyl substituents as 5-HT6 receptor ligands. The chiral sulphonyl derivatives 15a and 17a showed high affinity at 5-HT6R with the Ki of 23.4 and 20.5nM, respectively. The lead compound from the series 15a has acceptable ADME properties, adequate brain penetration and is active in animal models of cognition like Novel Object Recognition Task (NORT) and water maze.

- 3-ALKYL-5-FLUOROINDOLE DERIVATIVES AS MYELOPEROXIDASE INHIBITORS
-
The invention relates to a compound of formula (Ia) wherein n is an integer between 2 and 10, R1 and R2 independently represent a substituent selected from the group consisting of hydrogen, C1-C10 alkyl, C3-C10 cycloalkyl and aminoalkyl, or R1 and R2 are taken together with the nitrogen atom to which they are attached to form a four to ten-membered heterocycle, R5 represents independently in each of the n units a substituent selected from the group consisting of hydrogen, C1-C10 alkyl, halogen, alkoxy, aminoalkyl and alkylamino; or a pharmaceutically acceptable salt thereof, with the proviso that the 5-fluorotryptamine is excluded, for the treatment or the prophylaxis of neuroinflammatory diseases or disorders. The invention also relates to a pharmaceutical composition, a method for inhibiting myeloperoxidase enzyme activity, to a method for inhibiting Low density lipoproteins oxidation.

- Structure-based design, synthesis, and pharmacological evaluation of 3-(Aminoalkyl)-5-fluoroindoles as myeloperoxidase inhibitors
-
Oxidized low-density lipoproteins (LDLs) accumulate in the vascular wall and promote local inflammation, which contributes to the progression of the atheromatous plaque. The key role of myeloperoxidase (MPO) in this process is related to its ability to modify APO B-100 in the intima and at the surface of endothelial cells. A series of 3-(aminoalkyl)-5-fluoroindole analogues was designed and synthesized by exploiting the structure-based docking of 5-fluorotryptamine, a known MPO inhibitor. In vitro assays were used to study the effects of these compounds on the inhibition of MPO-mediated taurine chlorination and oxidation of LDLs. The kinetics of the interaction between the MPO redox intermediates, Compounds I and II, and these inhibitors was also investigated. The most potent molecules possessed a 4- or 5-carbon aminoalkyl side chain and no substituent on the amino group. The mode of binding of these analogues and the mechanism of inhibition is discussed with respect to the structure of MPO and its halogenation and peroxidase cycles.
