The title compound, C(5)H(6)N(3)O(2) (+)·ClO(4) (-), is comprised of discrete perchlorate anions and 2-amino-3-nitro-pyridinium cations. The anion has a typical tetra-hedral geometry while the cation presents a nearly planar [maximum deviation = 0.007 (8) Å] pyridinium ring. Undulating [C(5)H(6)N(3)O(2) (+)](n) chains extending along the c-axis direction are linked via N-H⋯O hydrogen bonds. The cations are further connected to the anions by N-H⋯O hydrogen bonds and weak C-H⋯O inter-actions, leading to the formation of a three-dimensional network.

Background: Senile dementia (SD) is a deteriorative organic brain disorder and it comprises Alzheimer's disease (AD) as a major variant. SD is shown impairment of mental capacities whereas AD is degeneration of neurons. According to World Health Organization (WHO) report; more than 55 million peoples have dementia and it is raising 10 million new cases every year.

Background: The present study recapitulates the potency of the novel synthesized piperazine-benzoquinone derivative as a lead molecule selectively targeting AChE along with the antioxidative potential for the management of cognitive decline in Alzheimer's disease.
Method: Novel piperazine-benzoquinone derivative was synthesized implementing appropriate synthetic procedures and was characterized by various spectral and elemental techniques. The purity of this synthetic analogue was ascertained by TLC, melting point determination and elemental analyses.
Background: Neurological disorders are at epidemic levels in the world today. Various proteins are being targeted for the development of novel molecular therapeutics; however, no small-molecule inhibitors have been discovered. Recent studies suggest that there are few molecules in clinical trials for various secretase (α, β, and γ), caspase, and calpain inhibitors.

A series of chiral hybrid diphosphorus ligands incorporating a conformationally flexible tropos diphenylmethane-based phosphoramidite unit have been developed and evaluated in the Rh-catalyzed asymmetric hydrogenation of 2-(1-arylvinyl)anilides and α-enamides, leading to up to >99% yield and 99% enantiomeric excess. Preliminary results from comparative studies showcased the extraordinary catalytic performance of these chiral tropos phosphine-phosphoramidite ligands, with a competency essentially superior to those of well-established ligands with a regular rigid backbone.
