Development of stable self-assembled nanostructures (especially vesicles and liposomes), and understanding their physicochemical behaviors in aqueous solution is a long-standing topic of interest in chemical and biochemical research. In this progressive area, we report for the first-time formati...

The interaction of two decylammonium surfactants, didecyldimethylammonium bromide (D) and decyltrimethylammonium bromide (S), with native α-, β-, and γ-cyclodextrins (CDs) was systematically examined using the isothermal titration calorimetry (ITC). The measured heat data at five temperatures...

Numerous studies have suggested that the central α2-adrenergic receptor system may exert an important role in some types of human anxiety. The anxiolytic-like activity and potential side effect-like activities of the novel and purported α2-adrenergic compound TDIQ (5,6,7,8-1,3-dioxolo[4,5-g]is...

5,6,7,8-Tetrahydro-1,3-dioxolo[4,5-g]isoquinoline (TDIQ) is a conformationally restricted phenylalkylamine related in structure to amphetamine and N-methyl-1-(3,4-methylenedioxyphenyl)-2-aminopropane (MDMA) that does not act as a locomotor stimulant. To further evaluate this agent, a group of si...

There is considerable evidence that α2-adrenergic receptor activity exerts a pivotal role in initiation of feeding behavior. The appetite suppressant and monoamine release effects of TDIQ (5,6,7,8-tetrahydro-1,3-dioxolo[4,5-g]isoquinoline), a putative selective α2-adrenergic compound, were com...

This investigation is based on the premise that conformational restriction of abused phenylalkylamines in a tetrahydroisoquinoline conformation alters their pharmacology in such a manner that their original action is lost and that a new action emerges. TDIQ or 5,6,7,8-tetrahydro-1,3-dioxolo[4,5-...

Polyamidoamine (PAMAM) dendrimers of G1.0 and 2.0 were synthesized by the repeated Michael addition and ester aminolysis of ethylenediamine and methyl acrylate. Through the reductive amination reaction of primary amines in PAMAM and carbonyl groups in 4-oxo-2,2,6,6-tetramethylpiperidine-1-oxyl (...

Block copolymers of 2,2,6,6-tetramethyl-4-piperidyl methacrylate and glycidyl methacrylate were prepared by atom transfer radical polymerization. The block copolymer was immobilized on an indium-doped tin oxide substrate by simply coating the copolymer solution and annealing. The copolymer layer...

4-Oxo-4,5-dihydro-3H-pyrrolo[2,3-c]quinoline-1-carboxylic acid ethyl ester was obtained when TosMIC was reacted with 3-methylene-oxindole acetic acid ethyl ester. An alternative synthesis to this pyrroloquinolone was performed via a reduction of a 2,3,4-trisubstituted pyrrole obtained in turn by...

Myeloid differentiation protein 2 (MD2) is an essential molecule which recognizes lipopolysaccharide (LPS), leading to initiation of inflammation through the activation of Toll-like receptor 4 (TLR4) signaling. Caffeic acid phenethyl ester (CAPE) from propolis of honeybee hives could interfere i...

Mg doped bismuth titanate ceramics Bi4Ti3-xMgxO12 (x = 0.2, 0.4, 0.6) (BMgT) synthesized using a solution combustion technique are studied in this paper. This work examines the effect of Mg doping at B site of bismuth titanate on its crystalline structure, ferroelectric properties and electrical...

We present a novel, low-cost approach to fabricate piezoelectric nanogenerators using Bismuth titanate (BiT)/Polydimethylsiloxane (PDMS) nanocomposite.
