:: The most intriguing area of scientific study and engineering applications is to synthetize materials that can autonomously heal damage similar to biological tissues. Since the concept of self-healing materials was established, several variations of self-healing polymer materials have been developed based on distinct healing techniques. This review outlines the most recent breakthroughs in self-healing polymers and utilizes the opportunity to categories the descriptions of self-healing technologies in the literatures according to extrinsic and intrinsic routes (noncovalent bonds, physical interaction, and covalent bonds). The major focus is on the routes and strategies used to generate self-healing polymer materials. In addition, the strengths and weaknesses of polymer materials with different self-healing routes and strategies in terms of mechanical and self-healing properties were summarized. Furthermore, we also reviewed the progress of the development from a single selfhealing mechanism to multiple self-healing mechanisms to achieve balanced comprehensive performance. Finally, the future trajectory of self-healing polymers is envisioned.

Of note, the present articles exploited several water-mediated and solventfree methodologies for tetrazole synthesis. The important key features of tetrazole synthesis were pinpointing in each synthetic scheme which provides excellent guide to those searching for selective procedure to achieve the desired transformation. This review seeks to present a timely account (2011-2023) on the splendid array of ecofriendly procedures of synthesis known today for the preparation of tetrazole derivatives from different starting materials. The rational of this review is to enlighten recent advancements in the synthesis of tetrazole derivatives from different substrates.

: Synthetic organic molecules are vital for human life, serving as medications, pesticides, dyes, and food additives. Organic synthesis provides routes for the production of these molecules. The traditional methods of organic synthesis require energy, solvents, time, and certain conditions based on the nature of the reactions. To address the issues associated with conventional processes, various environmentally friendly (green) methodologies have been developed. Catalysts are crucial in many chemical methods. Chemists aim to develop catalysts that are cost-effective, easy to recover, and can be synthesized with high catalytic activity and renewability. Natural montmorillonite clay is an ideal material for efficient catalysts since it satisfies all these requirements. This review focuses on the recent advances in the development of renewable nanocatalysts made from montmorillonite to be used for the synthesis of various organic compounds.

: In this study, some new pyrazoline derivatives bearing cyano or nitro groups were synthesized. The structures of the compounds were characterized by IR, 1H-NMR, 13C-NMR and elemental analysis data. The ABTS·+, DPPH·, CUPRAC and β-Carotene/linoleic acid assays were carried out to determine the antioxidant activity of the synthesized pyrazolines. Compound P14 showed higher antioxidant activity than the standard substance BHA with IC50 values of 1.71±0.31 μM and 0.29±0.04 μM in ABTS+ and β-carotene/linoleic acid assays, respectively. Compound P12 also exhibited higher antioxidant activities than BHA with an IC50 value of 0.36±0.14 μM in β-carotene/linoleic acid analysis. In activity studies of pyrazolines against cholinesterase (AChE and BChE), tyrosinase, α-amylase and α- glucosidase, compound P1 (IC50 = 39.51±3.80 μM) showed higher activity against α-amylase and compounds P5 and P12 displayed higher activity against α-glucosidase than acarbose with IC50 values of 14.09±0.62 and 83.26±2.57 μM, respectively. The drug-like properties such as Lipinski and Veber, bioavailability and toxicity risks of the synthesized compounds were also evaluated. The compounds were predicted to be compatible with Lipinski and Veber rules, have high bioavailability and low toxicity profiles. Moreover, molecular docking studies were performed to better understand the high activity of the compounds against a-amylase and a-glucosidase enzymes.

: Sporotrichosis, recognized by the World Health Organization (WHO) as a neglected tropical disease and classified among significant fungal health concerns, remains both underestimated and underreported. There is a profound impact of sporotrichosis on public health, affecting both humans and domestic animals. The causative agents are fungi within the Sporothrix genus, primarily transmitted through traumatic exposure to contaminated soil, plants, decomposing materials, or through scratches from infected animals, notably cats. While sporotrichosis is a global concern, its prevalence is particularly noteworthy in tropical and subtropical regions. The limited treatment options for sporotrichosis, with itraconazole as the preferred choice, underscore the challenges posed by fungal infections. Issues such as toxicity and drug resistance further complicate effective management. Consequently, this review aims to elucidate key objectives: identification of novel synthetic compounds revealed in the literature, highlighting ongoing efforts to develop new treatments against sporotrichosis, examining promising anti-sporothrix natural products, and providing an overview of endeavors to repurpose approved drugs. The key findings from the study underscore the urgent need for diversified and effective drugs for the treatment of Sporotrichosis.
:孢子丝菌病(Sporotrichosis)被世界卫生组织(WHO)视为一种被忽视的热带疾病,并被列为重大真菌健康问题之一。孢子丝菌病对公共卫生影响深远,人类和家畜都会受到影响。病原体是孢子丝菌属中的真菌,主要通过接触受污染的土壤、植物、腐烂物质或被感染动物(尤其是猫)抓伤而传播。虽然孢子丝菌病是全球关注的问题,但它在热带和亚热带地区的流行尤为显著。孢子丝菌病的治疗方案有限,伊曲康唑是首选,这凸显了真菌感染带来的挑战。毒性和耐药性等问题使有效治疗更加复杂。因此,本综述旨在阐明以下关键目标:确定文献中揭示的新型合成化合物,强调目前为开发治疗孢子丝菌病的新疗法所做的努力,研究有前景的抗孢子丝菌天然产品,并概述为重新利用已批准药物所做的努力。本研究的主要发现强调了治疗孢子丝菌病急需多样化的有效药物。

Recent Progress in the Synthetic Methods of Pyrazoloquinoline Derivatives (Part I) 吡唑喹啉衍生物合成方法的最新进展(第一部分)
IF 2.6 3区 化学 Q3 CHEMISTRY, ORGANIC Pub Date : 2024-01-24 DOI: 10.2174/0113852728285959240108060645

The focus of this review is on the synthetic routes available for different types of pyrazoloquinoline derivatives. There are three types of synthetic methods: i) from pyrazole derivatives; ii) from quinoline derivatives; and iii) miscellaneous methods. The position of the linkage between pyrazole and quinoline rings determines the seven isomers of pyrazoloquinolines. The purpose of this review is to provide a guide for both synthetic and medicinal chemists to discover and design new pyrazoloquinolines for medical purposes.
