A pentacyclic triterpenoid produced from medicinal herbs, fruits, and vegetables, Ursolic acid (UA) has pharmacological activity. This review provides a comprehensive overview of the interactions of UA with molecular targets, its various mechanisms of action, and its clinical implications in cancer therapy. Numerous studies have been conducted on the pharmacological effects of UA, and its biological benefits, such as its a Read More

Minerals occurring on earth have been used as raw materials by mankind for thousands of years. Currently, more than 6000 mineral species are known, and a few of them are common or abundant. It has long been known that minerals can catalyse chemical processes. The catalytic activity of metallic ore minerals has been investigated primarily in coal liquefaction and prebiotic chemistry and, to a lesser extent, in organic sy Read More

A practical and novel approach for the regioselective synthesis of 3-arylthioindole derivatives has been accomplished using a combination of indole substrates with p-toluene sulfonyl hydrazide. This methodology employs NIS as the oxidant and PPh3 as the reductant to give the desired 3-arylthioindoles in good to excellent yields. This method offers several advantages, including simplicity, operational ease, and broad substrate scope.

Effective and “green” synthesis of tetraketone derivatives was elaborated. The last compounds developed prominent bactericide activity against both MIC and MBC S. aureus (ATCC-6538P) bacteria. The novelty of this approach is concluded in the application of Al(OH)3 catalyst for the Knoevenagel-Michael cascade reaction of aromatic aldehydes and 1,3-cyclic diketones in water. The process is chemoselective and affo Read More

Organocatalysis has been recognized as a part of chemical research for a long time, and it gained significant attention in catalysis in recent decades. Amine catalyst is a substantial type of organocatalysis, and it is successively employed for the activation of carbonyl compounds. This manuscript delves into the exploration of a proline-based organocatalyst for the synthesis of arylidene benzofuranone intermediates, a Read More

For the first time, a sonochemical method has been developed for the structural rearrangement of [5,6]-open mono- and poly adducts of fullerene C60 containing spirocyclic fragments of camphor analogs into [6,6]-closed isomers. The isomerization reaction occurs with quantitative yield under mild conditions: 1 hour at room temperature. A probable mechanism of sonochemical isomerization has been proposed. Mono- and poly Read More

Organo-modified carbon nanotubes have recently gained the interest of many research groups. The potential for applying a new generation of organo-modified carbon nanotubes in many technological fields reveals the importance of covalent modifications on nanotubes. In this study, using the microwave synthesis method, multi-walled carbon nanotube (MWCNT) thiophenol derivatives were obtained with a thioesterification Read More

The high dipolarophile structure of MWCNT compounds enables them to be used as a reactive 2π member in 1,3-dipolar cycloaddition reactions. N-substituted glycine ester compounds and employed 1,3-dipolar cycloaddition reactions involving azomethine-ylides for the synthesis of multiwalled carbon nanotube compounds that underwent covalent modification. Initially, N-substituted glycine esters (3a) and N-substituted glycine Read More
