glycyrrhetinic acid/breast neoplasms

Late-stage functionalization (LSF) aids drug discovery efforts by introducing functional groups onto C-H bonds on pre-existing skeletons. We adopted the LSF strategy to synthesize analogues of the abundantly available triterpenoid, glycyrrhetinic acid (GA), by introducing aryl groups in the A-ring,

In the present work, QSAR model was derived by multiple linear regression method for the prediction of anticancer activity of 18β-glycyrrhetinic acid derivatives against the human breast cancer cell line MCF-7. The QSAR model for anti-proliferative activity against MCF-7 showed high correlation

Triple-negative breast cancers (TNBCs) are one of the most aggressive and complex forms of cancers in women. TNBCs are commonly known for their complex heterogeneity and poor prognosis. The present work aimed to develop a predictive 2D and 3D quantitative structure-activity relationship (QSAR)

BACKGROUND Radix Glycyrrhiza has been used in China for thousand years to treat cancer. However, focus on its tumor-suppressing mechanism has been concentrated on its effect on tumor cell growth and apoptosis. OBJECTIVE With the aid of a panel of human breast cancer cell lines, we reveal that

Triple negative breast cancer(TNBC) has generated growing interests due to its aggressive biologic behavior and absence of targeted therapy approach. Glycyrrhizin(GL) from licorice root and its metabolite, glycyrrhetinic acid(GA) have shown extensive bioactivities in clinic. Here, we demonstrate

Triterpenes found in plants display a multitude of biological activities, including anti-tumor properties. The present study investigates the effect of 18β-glycyrrhetinic acid (GRA) a pentacyclic triterpenoid of the β-amyrin type, isolated from the root of Licorice (Glycyrrhizza glabra) on human

Gap junctions (GJs) serve the principal role in the antineoplastic (cytotoxicity and induced apoptosis) effect of chemical drugs. The aim of the present study was to determine the effect of GJ intercellular communication (GJIC) composed of connexin 43 (Cx43) on adriamycin cytotoxicity in breast

This in vitro study on MCF-7 and ZR-75-1 breast cancer cells showed that the antiproliferative action of glucocorticosteroids (GCS) on breast cancer cells is weakened by a high oxidative activity of 11 beta-hydroxysteroid dehydrogenase (11 beta-HSD; EC 1.1.1.146): both endogenic as well as synthetic

Manipulating the metabolism of glucocorticoids may serve as a useful adjunct in the treatment of breast cancer. The 11beta-hydroxysteroid dehydrogenase type 2 enzyme (11betaHSD2) potently inactivates glucocorticoids thereby protecting the non-selective mineralocorticoid receptor (MR) in fluid

UNASSIGNED The structural modification of natural products with the aim to improve the anticancer activity is a popular current research direction. The pentacyclic triterpenoid compounds oleanolic acid (OA) and glycyrrhetinic acid (GA) are distributed widely in nature. UNASSIGNED In this study,

A series of new glycyrrhetinic acids and oleanolic acids has been designed and synthesized based on the principles of combinatorial chemical synthesis. Their anticancer activities were further studied by using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) method with

A total of forty novel glycyrrhetinic acid (GA) derivatives were designed and synthesized. The cytotoxic activity of the novel compounds was tested against two human breast cancer cell lines (MCF-7, MDA-MB-231) in vitro by the MTT method. The evaluation results revealed that, in comparison with GA,

Glycyrrhetinic acid (GA) is a natural product with certain antitumor activity. In order to enhance the cytotoxicity, a total of eighteen derivatives of GA were designed and synthesized. Their cytotoxicity against MDA-MB-231cells (human breast cancer cells) and HeLa cells (human cervical cancer

OBJECTIVE The major hurdle of current drug carrier against hepatocellular carcinoma (HCC) is the lack of specific and selective drug delivery to HCC. In this study, a novel glycyrrhetinic acid (GA) and poly(L-Histidine) (PHIS) mediated polymeric drug delivery system was developed to target HCC that

Oleanolic acid (OA) and glycyrrhetinic acid (GA) are natural products with anticancer effects. Cinnamic acid (CA) and its derivatives also exhibited certain anticancer activity. In order to improve the anticancer activity of OA and GA, we designed and synthesized a series of novel OA-CA ester
