The compound 3 on further reaction with different electrophiles (4a-o) yielded the target compounds 5a-o, which were characterized with the help of FTIR, 1 H-, 13 C-NMR spectroscopic and EI-MS & HR-EI-MS spectrometric data. These sulfonamides (5a-o) were evaluated for their acetylcholinesterase (AChE) and α -glucosidase inhibitory potential.

TB is the leading cause of death from a single infectious agent, ahead of HIV/AIDS. The African continent bears the highest global TB/HIV burden and over 50% of TB cases in sub-Saharan Africa are co-infected with HIV. With an estimated 1.7 billion people (23% of the world’s population) with latent TB infection, there is an urgent need to develop drugs that will eradicate or control the disease. Moreover, the emergence of multi-drug resistant tuberculosis (MDR-TB) and extensively drug resistant tuberculosis (XDR-TB) have accelerated the need for new antitubercular agents with novel biological targets and different mechanism of action. Among the wide spectra of heterocyclic compounds, benzopyran derivatives have displayed diverse biological applications. Found in many natural products, this scaffold together with its synthetic analogs has intrigued medicinal chemists to explore its applicability as anti-TB drugs. To further intensify research in this area, there is need to gather the latest information on benzopyrans as antimycobacterial agents. This review presents an overview of recent developments (2000 -2018) in anti-TB applications of benzopyrans, both the synthetic analogs and isolated natural products. The objective of this review is to focus on active benzopyran analogs and structure activity relationship (SAR) analysis. We envisage that this review will be helpful in rational design of potent, less toxic benzopyran-based anti-TB drug candidates. a the of mycobacterial cell wall lipid biosynthesis. oxo-4H-chromene-3-carbonitriles with ethyl cyanoacetate.

The design of a material like bone is a great challenge, especially when combining the ideal mechanical strength, porosity, and bioactivity. This work focused on the development of a new candidate for bone substitute combining hydroxyapatite (HAp) and silk fibroin (SF). The silk fibroin, obtained from the cocoons of the silkworm (Bombyx mori), was dissolved using a ternary solution of calcium, ethanol, and water. HAp was co-precipitated dropping phosphate solution (Na2HPO4) in SF at a constant stirring. The final composite, 75%HAp/25%SF, were framed using a hydraulic system varying the pressure to find the best candidate. Physical and chemical characterizations were evaluated, as well as the bioactivity and cytotoxicity. Results showed excellent chemical and physical properties, like the trabecular bone. The 75%HAp/25%SF biocomposite was safe to CHO cells and presented great bioactivity being an alternative candidate to the bone regeneration field.","PeriodicalId":19547,"journal":{"name":"Organic & Medicinal Chemistry International Journal","volume":"54 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85818136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
