Protective effects of thymogen analogues, modified by D-alanine, in hydrazine liver damage

Research Results in Pharmacology
Introduction: It is known that the insertion of D-amino acids into the structure of a peptide molecule can increase its half-life. The pharmacological drug Thymogen was modified with D-alanine from the N- and C-terminus of the molecule.

Synthesis of Tricyclic Condensed Rings Incorporating the Pyrazole or Isoxazole Moieties Bonded to a 4-Piperidinyl Substituent

Molecules, 2013
In this paper we report the synthesis of new compounds based on the pyrazole and isoxazole framework fused to a cycloalkene unit, and bearing as a substituent the 1-piperidinyl group as new examples of potential antipsychotic molecules.
