Emodin Exerts an Antiapoptotic Effect on Human Chronic Myelocytic Leukemia K562 Cell Lines by Targeting the PTEN/PI3K-AKT Signaling Pathway and Deleting BCR-ABL. Integr Cancer Ther 2017; 16:526-539. [PMID: 27698265 PMCID: PMC5739139 DOI: 10.1177/1534735416664784] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2016] [Revised: 07/15/2016] [Accepted: 07/19/2016] [Indexed: 12/05/2022] Open
Abstract
The BCR-ABL kinase inhibitor, imatinib mesylate, is the front-line treatment for chronic myeloid leukemia, but the emergence of imatinib resistance has led to the search for alternative drug treatments. There is a pressing need, therefore, to develop and test novel drugs. Natural products including plants, microorganisms, and halobios provide rich resources for discovery of anticancer drugs. In this article, we demonstrate that emodin inhibited the growth of K562 cells harboring BCR-ABL in vitro and in vivo, and induced abundant apoptosis, which was correlated with the inhibition of PETN/PI3K/Akt level and deletion of BCR-ABL. These findings suggest that emodin is a promising agent to kill K562 cells harboring BCR-ABL.

[PMID: 27368748 DOI: 10.1016/j.ejpb.2016.06.019] [Citation(s) in RCA: 57] [Impact Index Per Article: 7.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2016] [Revised: 06/14/2016] [Accepted: 06/24/2016] [Indexed: 12/20/2022]
Abstract
The present study focuses on the development of an effective topical nanogel formulation of two anti-psoriatic drugs; Acitretin (Act) and Aloe-emodin (AE) using natural polymer chitin. Simple regeneration chemistry was used to prepare Chitin Nanogel Systems (CNGs). The developed control chitin (CNGs) nanogels, acitretin loaded chitin nanogels (ActCNGs) and aloe-emodin loaded chitin nanogels (AECNGs) were characterized by DLS, SEM, FTIR, XRD and TG-DTA. The systems were found to be spherical in shape with a size range of 98±10, 138±8 and 238±6nm having zeta potential values of +28±3, +27±3 and +25±6mV for CNGs, ActCNGs and AECNGs respectively. The in vitro haemolysis assay revealed that all the nanogel systems are blood compatible. The systems exhibited higher swelling and release at acidic pH. The ex vivo skin permeation studies using porcine skin confirmed the higher deposition of the systems at epidermal and dermal layers, which was confirmed further by fluorescent imaging. The in vivo anti-psoriatic activity study using Perry's mouse tail model and skin safety studies confirmed the potential benefit of the system for topical delivery of acitretin and aloe-emodin in psoriasis.

Abstract
Aloe-emodin, a natural polyphenolic anthraquinone, has shown various beneficial bioactivities in vitro. The aim of this study was to investigate the pharmacokinetics and metabolism of aloe-emodin. Aloe-emodin was intravenously and orally administered to rats. The concentrations of aloe-emodin and rhein, a metabolite of aloe-emodin, were determined by HPLC method prior to and after hydrolysis with β-glucuronidase and sulfatase/β-glucuronidase. The results showed that the systemic exposures of aloe-emodin and its metabolites were ranked as aloe-emodin glucuronides (G) > rhein sulfates (S) > aloe-emodin > rhein and rhein G when aloe-emodin was given intravenously. In contrast, when aloe-emodin was administered orally, the parent form of aloe-emodin was not absorbed per se, and the systemic exposures of its metabolites were ranked as aloe-emodin G > rhein G > rhein. In conclusion, the metabolites of aloe-emodin are more important than the parent form for the bioactivities in vivo. Copyright © 2016 John Wiley & Sons, Ltd.
