Abstract A series of novel 2,5-diarylpyrazolo[1,5-a]pyrimidin-7-amines were designed as COX-2 inhibitors by molecular docking studies and their synthesis was accomplished via an expeditious one-pot reaction. Structures of the compounds were established by

A series of pyrazolo[5′,1′:2,3]pyrimido[4,5-b][1,4]benzoxazines (4a-n), a new heterocyclic ring system has been synthesized starting from 2H-3-oxo-[1,4]-benzoxazines (1a-d) and 5(3)-aminopyrazoles (3a-d) via the intermediates 3-chloro-2-formylidine-1,4-be

A simple one-pot method for the microwave-assisted synthesis of substituted pyrazolo[1,5-a]pyrimidinones, a core scaffold in many bioactive and pharmaceutically relevant compounds, has been established. A variety of substituents was tolerated at the 2 and 5 positions, including functionalized aryls, heterocycles, and alkyl groups.
Study of regioselectivity of reactions between 3(5)-aminopyrazoles and 2-acetylcycloalkanones

, p. 1111 - 1120 (2013/01/15)
Regioselectivity was examined of reactions between nine 3(5)-aminopyrazoles and 2-acetylcyclopentanone and 2-acetylcyclohexanone under various conditions. A series of cyclopenta[e]pyrazolo-[1,5-a]pyrimidines was obtained. The highest regioselectivity of the reaction was observed in alcohol at 20°C in the presence of a catalytic quantity of trifl uoroacetic acid. The regiostructure of compounds was established by 1H and 13C NMR spectroscopy. Pleiades Publishing, Ltd., 2012.
Novel potent neuropeptide Y Y5 receptor antagonists: Synthesis and structure-activity relationships of phenylpiperazine derivatives

A series of phenylpiperazine derivatives were synthesized and evaluated for their neuropeptide Y (NPY) Y5 receptor antagonistic activities. The benzindane portion of 2 was replaced by 1-phenylpiperazine, resulting in novel urea derivative 3f. Subsequent optimization of the phenylpiperazine template by substitution of the phenyl moiety resulted in a series of (2-methanesulfonamidephenyl)piperazine derivatives that showed potent binding affinity and antagonistic activity for the Y5 receptor.
