    Synthesis, in vitro, and docking analysis of c-3 substituted coumarin analogues as anticancer agents
    (Bentham Science Publishers, 2020-01-28T00:00:00) Thakur, Anuradha; Kaur, Kamalpreet; Sharma, Praveen; Singla, Ramit; Singh, Sandeep; Jaitak, Vikas
    Background: Breast cancer (BC) is a leading cause of cancer-related deaths in women next to skin cancer. Estrogen receptors (ERs) play an important role in the progression of BC. Current anticancer agents have several drawbacks such as serious side effects and the emergence of resistance to chemotherapeutic drugs. As coumarins possess minimum side effects along with multidrug reversal activity, it has a tremendous ability to regulate a diverse range of cellular pathways that can be explored for selective anticancer activity. Objectives: Synthesis and evaluation of new coumarin analogues for anti-proliferative activity on human breast cancer cell line MCF-7 along with exploration of binding interaction of the compounds for ER-? target protein by molecular docking. Methods: In this study, the anti-proliferative activity of C-3 substituted coumarins analogues (1-17) has been evaluated against estrogen receptor-positive MCF-7 breast cancer cell lines. Molecular interactions and ADME study of the compounds were analyzed by using Schrodinger software. Results: Among the synthesized analogues, 12 and 13 show good antiproliferative activity with IC50 values 1 and 1.3 ?M, respectively. Molecular docking suggests a remarkable binding pose of all the seventeen compounds. Compounds 12 and 13 were found to exhibit a docking score of -4.10 kcal/mol and -4.38 kcal/mol, respectively. Conclusion: Compounds 12 and 13 showed the highest activity followed by 1 and 5. ADME properties of all compounds were in the acceptable range. The active compounds can be taken for lead optimization and mechanistic interventions for their in vivo study in the future. � 2021 Bentham Science Publishers.

    Recent developments of C-4 substituted coumarin derivatives as anticancer agents
    (Elsevier Masson SAS, 2016) Dandriyal, Jyoti; Singla, Ramit; Kumar, Manvendra; Jaitak, Vikas
    Cancer is a prominent cause of death in global. Currently, the numbers of drugs that are in clinical practice are having a high prevalence of side effect and multidrug resistance. Researchers have made an attempt to expand a suitable anticancer drug that has no MDR and side effect. Coumarin scaffold became an attractive subject due to their broad spectrum of pharmacological activities. Coumarin derivatives extensively explored for anticancer activities as it possesses minimum side effect along with multi-drug reversal activity. Coumarin derivatives can act by various mechanisms on different tumor cell lines depending on substitution pattern of the core structure of coumarin. Substitution on coumarin nucleus leads to the search for more potent compounds. In this review, we have made an effort to give a synthetic strategy for the preparation of C-4 substituted coumarin derivatives as anticancer agents based on their mechanism of action and also discuss the SAR of the most active compound. ? 2016 Elsevier Masson SAS.

    Coumarins as anticancer agents: A review on synthetic strategies, mechanism of action and SAR studies
    (Elsevier Masson SAS, 2015) Thakur, Anuradha; Singla, Ramit; Jaitak, Vikas
    Abstract Coumarins are fused benzene and pyrone ring systems which prompt biological investigation to assess their potential therapeutic significance. It possesses immeasurable anticancer potential with minimum side effects depending on the substitutions on the basic nucleus. Coumarins have a tremendous ability to regulate diverse range of cellular pathways that can be explored for selective anticancer activity. This is the first standalone review that emphasis on the assorted retrosynthetic approaches, important targets for molecularly targeted cancer therapy and structure activity relationship studies that highlight the chemical groups responsible for evoking the anticancer potential of coumarin derivatives reported from 2011 to 2014. ? 2015 Elsevier Masson SAS.
