Development of an imidazole salt catalytic system for the preparation of bis(indolyl)methanes and bis(naphthyl)methane.

open access: yesPLoS ONE, 2019
Imidazolium salts are shown to catalyze the rapid room temperature reaction of indoles or naphthol with aldehydes to provide bis(indolyl)methanes or bis(naphthol)methane in excellent yields and the reaction proceeds optimally in dichloromethane with no ...

Maternal nutrition as a key determinant of placental and developing blood–brain barrier xenobiotic protective functions

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Suboptimal maternal nutrition alters placental and developing blood–brain barrier (BBB) protective function and is associated with increased fetal brain vulnerability. In the placenta, nutritional adversity may reduce the exchange surface area and promote meta‐inflammation, compromising barrier efficiency in a model‐ and context ...

One-Pot Synthesis of 2′-Aminobenzothiazolo-Arylmethyl-2-Naphthols Catalyzed by NBS under Solvent-Free Conditions

open access: yesThe Scientific World Journal, 2013
To develop a new facile protocol for the synthesis of 2′-aminobenzothiazolo-arylmethyl-2-naphthol derivatives, N-bromosuccinimide (NBS) was used as an efficient catalyst for the one-pot synthesis of 2′-aminobenzothiazolo-arylmethyl-2-naphthols in ...

A micromethod for the determination of arginine [PDF]

open access: yes, 1941
Micromethods for the determination of arginine based on the use of the Sakaguchi reagent have been described (14). This reagent gives a strong color with glycocyamine, arginine, and other monosubstituted guanidine derivatives.

Colocalization of Dopamine D1 and D2 Receptors With Neuronal Nitric Oxide Synthase in the Rat Paraventricular Nucleus: A Structural Basis for Dopaminergic–Nitrergic Interaction

open access: yesAnatomia, Histologia, Embryologia, Volume 55, Issue 4, July 2026.
ABSTRACT The paraventricular nucleus (PVN) plays a central role in neuroendocrine and autonomic regulation, including male sexual behaviour. Dopaminergic and nitrergic signalling within the PVN are functionally linked, but their cellular relationship remains unclear.

Rearrangements of Cycloalkenyl Aryl Ethers

open access: yesMolecules, 2016
Rearrangement reactions of cycloalkenyl phenol and naphthyl ethers and the acid-catalyzed cyclization of the resulting product were investigated. Claisen rearrangement afforded 2-substituted phenol and naphthol derivatives.

Ultrasound assisted synthesis of tetrahydrobenzocxanthene-11-ones using CAN as catalyst [PDF]

open access: yes, 2012
Tetrahydrobenzocxanthenes-11-ones was synthesized by a three component reaction of α-naphthol, aromatic aldehyde and dimedone. Ceric ammonium nitrate acts as a suitable eco-friendly catalyst for this method.
