    Medicinal chemistry aspects and synthetic strategies of coumarin as aromatase inhibitors: an overview
    (Springer, 2022-12-05T00:00:00) Ratre, Pooja; Kulkarni, Swanand; Das, Sweety; Liang, Chengyuan; Mishra, Pradyumna Kumar; Thareja, Suresh
    Coumarin is a bicyclic oxygen bearing heterocyclic scaffold formed by fusion of benzene with the pyrone ring. Because of its unique physicochemical characteristics and the ease with which it may be transformed into a wide range of functionalized coumarins during�synthesis, coumarin provides a privileged scaffold for medicinal chemists. As a result, many coumarin derivatives have been developed, synthesized, and evaluated to target a variety of therapeutic domains, thereby making it an attractive template for designing novel anti-breast cancer compounds. The main culprit in estrogen overproduction in the estrogen-dependent breast cancer (EDBC), is the enzyme aromatase (AR), and it is thought to be a significant target for the effective treatment of EDBC. Considering coumarins versatility, this review presents a detailed overview of diverse study of aromatase as a target for coumarins. An overview of structure�activity relationship analysis of coumarin core is also included so as to summarize the desired pharmacophoric features essential for design and development of aromatase inhibitors (AIs) using coumarin core. Identification of key synthesis techniques that could aid researchers in designing and developing novel analogues with significant anti-breast cancer properties along with their mechanism of action have also been covered in the current review.

    Polymeric nanoparticles of aromatase inhibitors: A comprehensive review
    (Bentham Science Publishers, 2020-09-29T00:00:00) Mishra, Keerti; Ratre, Pooja; Thareja, Suresh; Jain, Akhlesh K.
    Being the second most frequent cancer, breast cancer is emerging worldwide with an alarming rate, specifically in post-menopausal women. Targeted drug delivery has been in the focus for the successful treatment of breast cancer by enhancing the drug delivery efficiency and reducing the systemic toxicity of drugs. Al-so, it eliminates the drawbacks associated with conventional chemotherapy, including neuropathy, memory loss, cardiotoxicity and low RBCs count. This review elaborates the polymeric nanoparticles based formulation approaches for selective and sustained delivery for effective cure of breast cancer. However, breast cancer, a life-threatening disease, is mostly caused because of estrogen, thus aromatase inhibitors and estrogen synthesis inhibitors could prevent chances of breast cancer. The disease is associated with drug resistance and some side effects, which could be easily eliminated by using novel therapeutic approaches. Aromatase inhibitors, when en-trapped in nanoparticles, have shown sustained drug release, advocating themselves to be beneficial for the treatment of breast cancer. � 2021 Bentham Science Publishers.
