Saleem","doi":"10.2174/1570193x20666230821143410","DOIUrl":"https://doi.org/10.2174/1570193x20666230821143410","url":null,"abstract":"\u0000\u0000Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is one of the deadliest viruses among respiratory viruses which resulted in COVID-19 pandemic. The virus gets transmitted by the nasal route and moves down to the trachea, bronchi, and then to the lungs. Once replicated inside the alveolar cells, the SARS-CoV-2 makes the membrane of the alveolar sac porous, which causes the leaking of plasma from surrounding blood vessels into the alveolar sac leading to its buildup. This process results in the production of pro-inflammatory cytokines like interleukin-1β (IL-1β) and Tumor necrosis factor-α (TNF-α) by the helper T-cells at the site of the infection, causing difficulty in breathing. Plant-based alkaloids can be promising to treat viral infections. Plants have contributed to drug development against viruses like Herpes simplex virus (HSV), Human immunodeficiency virus (HIV), Hepatitis B virus (HBV), and viruses that cause respiratory diseases in humans. Plant alkaloids, either in the form of extract, infusion, or powder, have shown potential in treating viral diseases mainly by targeting the replication of viruses. Alkaloids like Tetrandrine, Oxymatrine, and Berberine have been shown to have a positive role in mediating pro-inflammatory cytokines like IL-1. These alkaloids thus inactivate the nuclear factor kappa-B (NF-kB) pathway, inhibiting the expression of its targeted genes, IL-1β and TNF-α. This inactivation of NF-kB results in reduced levels of IL-1 and TNF-α, and consequently reduced inflammation, decreasing the stress on the immune cells and increasing the ability of the patient to fight the infection. Despite vaccine development for SARS-CoV-2, the virus is continuously evolving into new varieties, posing a threat to humans and it is necessary to develop effective drug discovery programs. Natural products can pave the way in this regard. This review can contribute towards safer drug development against SARS-CoV-2, combating the threat of the ever-emerging variants of this virus.\u0000","PeriodicalId":18632,"journal":{"name":"Mini-reviews in Organic Chemistry","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2023-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41807009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has now been demonstrated that these molecules are present in a wide range of chemicals derived from plant sources. The capacity of 2-oxindole to be altered by various chemical groups to provide unique biological activities can be attributed to its function as a chemical framework for creating and devel-oping biological medications. Since the development of its first synthetic methodology, several re-search groups have developed protocols for producing 2-oxindole core and its bioactive derivatives. These include the traditional method and the transition/non-transition metal-catalyzed pathway for the synthesis of C3-non-substituted/C3-mono-substituted/C3-di-substituted core. Among those, C3-substitution-free 2-oxindole core synthesis is quite a challenging task, as C3-centre is very reactive. Syntheses of C3-substitution-free 2-oxindole cores have been less explored compared to other substi-tuted 2-oxindole derivatives. In this review article, we have mainly focused on showcasing the transi-tion metal-catalyzed synthetic methodology for the synthesis of 2-oxindoles with no substitution at C3-centre.","PeriodicalId":18632,"journal":{"name":"Mini-reviews in Organic Chemistry","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135876008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the heterocycle molecules is pyrazole with a five-membered heterocyclic ring with two neighboring nitrogen. Pyrazole and its derivatives have shown a broad range of biological applications like antibacterial, antifungal, antiviral, anti-inflammatory, anti-cancerous, and herbicidal activities. The study of synthetic routes suggests three broad ways: cyclo-condensation of hydrazine and its derivatives on 1,3 difunctional systems, dipolar cycloadditions, and multicomponent reactions. The synthesis of pyrazoles involves the usage of a conventional catalyst and more progressive and efficient nanoparticles as catalysts. The use of nanocatalysts is grabbing the attention of researchers owing to their more efficacy and reproducibility, low cost, reusability, ease of production, etc. The current review is an epigrammatic study on the importance of pyrazole as a biologically important moiety, recent advances in the three aforementioned routes to synthesize pyrazole and its derivatives, and a brief on the importance of nanocatalysts.\u0000","PeriodicalId":18632,"journal":{"name":"Mini-reviews in Organic Chemistry","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49125815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Heterocyclic compounds are rapidly increasing in number as a result of intensive synthetic research as well as their value in other synthetic procedures. More than 90% of medications contain heterocyclic rings, and a wide range of medicinal chemistry applications make use of these substances. There are always unique characteristics of an efficient approach for creating newly discovered heterocyclic compounds and their moieties. Due to their biological effects, including those that are anti-cancer, anti-inflammatory, anti-fungal, anti-allergic, antibacterial, antiviral, and anticonvulsant, heterocyclic compounds are crucial to medicinal chemistry. Today's world population is generally suffering from various neurodegenerative diseases. Out of that, the most prevailing disease is Alzheimer's. There are many causes of Alzheimer's disease-like acetylcholinesterase enzyme, tau protein, amyloid aggregation, oxidative stress, phosphodiesterase, and others. In these cases, oxidative stress plays a very important role in the progression of this disease. To combat this oxidative stress various antioxidant-derived drugs have been used but the problem is that Alzheimer's progression cannot be targeted with a single target drug because of the other factors that are involved in its progression. So to overcome that, a drug targeting multiple targets has been synthesized by using the antioxidant in previous reports. These drugs are more potent and efficacious than single-target drugs. This review focused on various multi-target ligands to target oxidative stress.\u0000","PeriodicalId":18632,"journal":{"name":"Mini-reviews in Organic Chemistry","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2023-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48495947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
