: Cucurbiturils are a class of macrocyclic compounds with highly polar carbonyl portals and a hydrophobic cavity. They are usually utilized as efficient host molecules in supramolecular chemistry applications due to their high binding affinity for positively charged or cationic compounds. This review investigates the application of CB[n] immobilization at semi-conductive interfaces to produce electrochemical sensors. Critical to the production of thin film electrode preparations is the solubility of the CB[n] to produce homogeneous thin films when deposited. The solubility of CB[n] molecules in organic and inorganic solvents is limited; however, CB[7] has been applied successfully in the production of a wide range of electrochemical sensors. Furthermore, we introduce simple drop-casting of efficiently solubilized CB[7] as a simple yet effective method for producing CB[7] modified electrochemical sensors for the sensitive reporting of dopamine in aqueous solutions in the concentration range of 3.33×10-9 to 1.16×10-8 M with a sensitivity of 0.315 µA/M, (n=3).

: Free radical reactions occupy an important position in synthetic organic chemistry as well as medicinal chemistry, significantly complementing and extending the synthesis of coumarin or quinolin-2-one compounds. Moreover, the use of constructing coumarin or quinolin-2-one compounds functionalized at the C3 position has certain advantages over traditional noble metalcatalyzed or high-temperature cyclization, which is more in line with the advocates of green chemistry. The design of alkenes or alkynes as radical acceptors for cascade reactions presents a novel and robust approach to obtaining coumarin or quinolin-2-one molecules. These radical cascade cyclization reactions have been well explored and studied over the past decade. As a result, we have compiled a review of the rapidly developing cutting-edge research in this field, featuring typical examples and in-depth exploration of the underlying mechanisms.

Abstract: Asciminib, also known as ACP-196, is the FDA-approved low-molecular ABL kinase inhibitor. The ABL kinase is a non-receptor tyrosine kinase that helps in cell growth and survival and is a key player in the development of chronic myeloid leukemia (CML) and Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ALL). The BCR-ABL fusion protein, which is formed by chromosomal translocation in CML and Ph+ ALL, results in the constitutive activation of ABL kinase, leading to uncontrolled cell growth and proliferation. To have a high binding affinity for the active site of the enzyme, structural biology and computer-aided drug design (CADD) concepts were applied to the design of asciminib so that it could specifically target the ABL kinase enzyme. The drug was synthesized and characterized in a laboratory. In its pharmacological studies, it has shown that asciminib is a potent and selective inhibitor of ABL kinase. Phase I clinical trials assessed its safety and efficacy, revealing that it is effective against tumors while causing minimal discomfort to patients. In addition to this, it was able to induce apoptosis and a cytogenetic response as well as inhibit the proliferation of CML and Ph+ALL cells in patients with CML. As this trial gave a positive response, phase II and III trials were conducted. In that sense, asciminib has shown to be highly effective, with response rates of over 90% in patients with these diseases. The safety and efficacy of asciminib were also evaluated in combination with other drugs, such as tyrosine kinase inhibitors and immunomodulatory drugs, and the results were promising. Overall, the discovery and development of asciminib showed that by using the concepts of pharmacology and CADD, a drug with a 90% positive rate response can be developed with a high tolerance level and lower side effects

Abstract: It is known that flotation is the main method of extracting non-ferrous metals. The need of modern society for precious metals is constantly growing, and deposits of easily reversible ores are being depleted. Therefore, the improvement of the reagent regime and the search for new flotation reagents is an urgent task. We analyzed the literature data on the synthesis and use of common collectors such as xanthates and dithiocarbamates. Particular importance is given to recent progress in the functionalization of xanthates and dithiocarbamates, their selective characteristics and flotation mechanisms. Progress in the field of flotation can be made in the use of new effective reagents and their combinations, as well as in the modification of already known collectors. The generalization of the material in this review will help in the development of this area. The mini-review summarizes the syntheses of collectors such as xanthates and dithiocarbamates with the increased selective properties in the flotation process of non-ferrous metals. Furthermore, this review provides an analysis of the developments in these studies, especially highlighting recent progress in the functionalization of xanthates and dithiocarbamates, their selective characteristics and flotation mechanisms.

Abstract: Water, a kind of abundant natural resource, is considered to be a green and desirable solvent for reasons of its low cost, high safety and environmental friendliness. This review article aims to briefly introduce the methodologies that have utilized water as reaction media under the aid of granular polytetrafluoroethylene (PTFE) to mediate reactions of a series of water-insoluble and high melting points substrates in a green, quantitative, fast, and stereoselective way in most situations. Besides, this review will be helpful to stimulate further study on both practical applications and mechanistic understanding of these aqueous reactions promoted by granular PTFE for the novel synthesis of interesting structures.

Abstract: 2-(Arylidene)benzo[b]thiophen-3(2H)one 1,1-dioxides are oxidized form of thioaurones. Various methods have been reported for their synthesis, e.g., a) condensation of benzo[b]thiophen-3(2H)one 1,1-dioxides with aryl aldehydes under acidic or basic conditions, b) oxidation of thioaurones with hydrogen peroxide or sodium perborate tetrahydrate, c) from the catalytic reaction of iodonium ylides with (bis(trifluoroacetoxy)iodo) benzene in presence copper(II)acetoacetonate, d)by ring contraction of 1-thioflavones in the presence of ceric ammonium nitrate. The reports have shown addition reactions with p-thiocresol in the absence of any catalyst, conjugated addition product without hetero ring opening with Grignard reagent, forms corresponding oxime and hydrazone with hydroxyl amine and phenyl hydrazine, respectively, produces polycyclic compounds with enamines, shows contrasting behavior with NBS and gives addition products with organophosphorus compounds in both hydroxylic and non-hydroxylic solvents which depends on reaction medium. In the present mini-review, we have discussed the various synthetic strategies and reactions of 2-(arylidene)benzo[b]thiophen-3(2H)one 1,1-dioxides, along with their reported utilities.

A class of chemicals known as flavonoids is widely distributed in various portions of plants, cereals, and vegetables. They have varied phenolic structures and these flavonoid molecules are known for the well-being improvement in living things. Today, a wide range of pharmaceutical, medicinal, & cosmetic materials possessed these key ingredients, known as flavonoids. Flavonoids can modulate the bioactivity of essential enzymes & their properties such as anti-mutagenic, anti-inflammatory, anti-oxidative, & anti-carcinogenic. The current patterns of flavonoid in research & development helps in the identification, isolation, characterization, & functions of flavonoids as well as their applications for better biological activities. In this article, we have discussed the natural existence and structural frameworks of the different classes of potential bioactive flavonoids. In addition to this, different synthetic strategies, and their mechanistic pathways for the preparation of different classes of flavonoids are also discussed thoroughly here. Owing to its tremendous natural existence and bioactivity, more research is still needed to further explore the usefulness of flavonoids for human wellness. The major challenge with the study of such flavonoids is the diversity of molecular structures & scarcity of data on their bioavailability. However, this article will be helpful for understanding the chemical aspect and several potential bioactivities of flavonoids

The mesoionic compounds have great importance due to their dipolar nature. They are versatile synthons in synthetic chemistry and possess various chemotherapeutic activities. The most important moiety found in mesoionic compounds is the sydnone ring system. Sydnone derivatives have stimulated much interest among synthetic researchers as a result of their unique dipolar, mesoionic character. This ring system is also associated with a wide variety of biological activities. Sydnone derivatives have various applications in synthetic and medicinal chemistry. Sydnones are very useful precursors for selective heterocycles (pyrazoles, imidazoles, oxadiazoles, oxazoles, thiazoles, and tetrazoles), which has also served to initiate research into their functionalization and cycloaddition chemistry, paving the way for stimulated extensive research on the use of sydnones in chemical and industrial applications. So, this review article offers a wide scope of synthesis and applications of sydnone derivatives.
