Structure-Activity Relationship Studies on Oxazolo[3,4- a]pyrazine Derivatives Leading to the Discovery of a Novel Neuropeptide S Receptor Antagonist with Potent in Vivo Activity

Neuropeptide S modulates important neurobiological functions including locomotion, anxiety, and drug abuse through interaction with its G protein-coupled receptor known as neuropeptide S receptor (NPSR). NPSR antagonists are potentially useful for the treatment of substance abuse disorders against which there is an urgent need for new effective therapeutic approaches. Potent NPSR antagonists in vitro have been discovered which, however, require further optimization of their in vivo pharmacological profile. This work describes a new series of NPSR antagonists of the oxazolo[3,4-a]pyrazine class. The guanidine derivative 16 exhibited nanomolar activity in vitro and 5-fold improved potency in vivo compared to SHA-68, a reference pharmacological tool in this field. Compound 16 can be considered a new tool for research studies on the translational potential of the NPSergic system. An in-depth molecular modeling investigation was also performed to gain new insights into the observed structure-activity relationships and provide an updated model of ligand/NPSR interactions.

Efficient one-pot synthesis of enantiomerically pure: N -protected-α-substituted piperazines from readily available α-amino acids

A new pathway towards enantiomerically pure 3-substituted piperazines, bearing a benzyl protecting group, has been developed in good overall yields (83-92%), starting from commercially available N-protected amino acids. The methodology represents an efficient and simple one-pot procedure, employing a synthetic sequence consisting of an Ugi-4 component reaction, a Boc-deprotection, an intramolecular cyclisation reaction and a final reduction (UDCR). From the benzyl protected precursors, the 2-substituted piperazines bearing a Boc-protecting group could consequently also be obtained via a simple protection and deprotection step of the corresponding piperazines. The practical utility of this methodology was demonstrated for chiral drug synthesis.

Synthesis and structure of 1,4-dipiperazino benzenes: Chiral terphenyl-type peptide helix mimetics

(Chemical Equation Presented) The terphenyl structure has been proven to be an ideal scaffold mimicking side-chain functionalities of peptidic α-helices. The synthesis of 1,4-dipiperazino benzenes, using stepwise transition metal-catalyzed N-arylation of chiral piperazines to a central benzene core is reported. The structure determination by X-ray crystallography reveals a geometrical arrangement of the hydrophobic side chains resembling the orientation of key i, i + 3, and i + 7 positions in a peptidic α-helix or in terphenyl helix mimetics.

Exploring the structure-activity relationships of [1-(4-(4- tert-butyl-3'-hydroxy)benzhydryl-4-benzylpiperazine] (SL-3111), a high-affinity and selective δ-opioid receptor nonpeptide agonist ligand

SL-3111 [1-(4-tert-butyl-3'-hydroxy)benzhydryl-4- benzylpiperazine] is a de novo designed, high-affinity and selective nonpeptide peptidomimetic agonist of the δ-opioid receptor. In a previous report we had described the unique biological characteristics of this ligand and also a need for further structural evaluation. To pursue this, we have introduced a completely different heterocyclic template (2 and 3), which, based on molecular modeling studies, may present the required structural features to properly orient the pharmacophore groups. We also have made more subtle changes to the original piperazine scaffold (5 and 11). The biological activities of these compounds revealed an important participation of the scaffold in the ligand-receptor interaction. To further explore functional diversity on the scaffold, we have maintained the original piperazine ring and introduced four different functionalities at position 2 of the heterocyclic ring (15a-d; a = CH2-O-CH2-Ph; b = Me; c = CH2Ph; d = CH2OH). The biological activities observed for these compounds showed a very interesting trend in terms of the steric effects of the groups introduced at this position. A decrease of almost 2000-fold in affinity and potency at the δ- receptor was observed for 15c compared with 15b. This difference may be explained if we postulate that the bioactive conformation of these peptidomimetics is close to the minimal energy conformations calculated in our study. On the basis of these findings we have realized the importance of this position to further explore and simplify the structure of future generations of peptidomimetic ligands.

Asymmetric Synthesis of 2,6-Methylated Piperazines

The complete series of enantiopure 2,6-methylated piperazines was synthesized utilizing two alternative reactions in the key bond-forming step.The dimethyl enantiomers, (2R,6R)- and (2S,6S)-2,6-dimethylpiperazine (1, 2), were prepared using either a diastereoselective triflate alkylation or a novel intermolecular Mitsunobu reaction to set the required stereochemistry.The monomethyl derivatives, (R)- and (S)-tert-butyl 2-methyl-1-piperazinecarboxylate (3, 4) were also synthesized employing the Mitsunobu cyclization strategy while the trimethyl compounds, (R)- and (S)-2,2,6- trimethylpiperazine (5, 6) were prepared using an enantiospecific triflate alkylation as the principal reaction.These methods represent efficient, general strategies for preparing a variety of 2,6-methylated piperazines for which the absolute stereochemistry can be readily controlled.
