Nanoparticles of nucleotide-free analogue of vitamin B formed in protein nanocarriers and their neuroprotective activity in vivo.

Recently, we have described the first supermolecular nanoentities of vitamin B derivative, viz. monocyano form of heptabutyl cobyrinate, unique nanoparticles with strong noncovalent intermolecular interactions, emerging optical and catalytic properties. Their nearest analogue, heptamethyl cobyrinate (ACCby), exhibits bioactivity.

Modulation of polyaniline memristive device switching voltage by nucleotide-free analogue of vitamin B.

Memristive devices offer essential properties to become a part of the next-generation computing systems based on neuromorphic principles. Organic memristive devices exhibit a unique set of properties which makes them an indispensable choice for specific applications, such as interfacing with biological systems. While the switching rate of organic devices can be easily adjusted over a wide range through various methods, controlling the switching potential is often more challenging, as this parameter is intricately tied to the materials used.

High Reactivity of Supermolecular Nanoentities of a Vitamin B Derivative in Langmuir-Schaefer Films Toward Gaseous Toxins.

Recently, we have described the first supermolecular nanoentities (SMEs) of a vitamin B derivative, viz., a monocyano form of heptabutyl cobyrinate ((CN)Cby), unique nanoparticles with strong noncovalent intermolecular interactions, and emerging optical and redox properties. In this work, the fast response of thin films based on the SMEs of the B derivative to gaseous toxins (viz.

Supermolecular Nanoentities of Vitamin B Derivative as a Link in the Evolution of the Parent Molecules During Self-Assembly at the Air-Water Interface.

Nanoarchitectures with promising properties have now been formed from many important biomolecules. However, the preparation of nanoparticles of vitamin B and its derivatives remains an ongoing research challenge. This paper describes the formation of supermolecular nanoentities (SMEs) of vitamin B derivatives, unique nanoparticles with strong noncovalent intermolecular interactions, emerging properties, and activity.

[Comparative studies of neurotrophic drugs based on brain hydrolysates].

The results of the analysis of comparative studies of neurotrophic drugs based on brain hydrolysates (BH) are presented. The most comprehensive comparative study of the BH drugs carried out by Zhang, et al. 2019 investigated the effects of four drugs (cognistar, cerebrolysate, cortexin, cerebrolysin) on a model of ischemic stroke in rats.
