[PMID: 39035924 PMCID: PMC11256079 DOI: 10.1021/acsomega.3c08078] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/15/2023] [Revised: 06/02/2024] [Accepted: 06/11/2024] [Indexed: 07/23/2024]
Abstract
The present study describes the development and validation of a simple and rapid HPLC method for the simultaneous quantification of exemestane and thymoquinone. The separation of both compounds was performed on a 5 μ C-18 column utilizing phase A as water/methanol (45:5 v/v) and phase B as acetonitrile (50 v/v) (total ratio of A/B = 40:60 v/v) in isocratic elution mode as the mobile phase at a flow rate of 0.8 mL/min. Further, the Box-Behnken design was used for optimizing the analytical method. The proposed method was validated for various parameters, and all parameters were found to be within an acceptable range. The simultaneous detection of both drugs was monitored at 243 nm with a retention time of 5.73 and 6.93 min, respectively. Moreover, the forced degradation studies were conducted under various stress conditions, and the relevance of the validated RP-HPLC method was further explored for the estimation of drugs from lipid-based nanoformulation. Taken together, the study construed the development of an efficient and robust method that could be used for the quantification of these agents in various in vitro as well as in vivo models.

Meroxest improves the prognosis of immunocompetent C57BL/6 mice with allografts of E0771 mouse breast tumor cells. Arch Med Sci 2016; 12:919-927. [PMID: 27695480 PMCID: PMC5016567 DOI: 10.5114/aoms.2014.45442] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/28/2014] [Accepted: 09/07/2014] [Indexed: 01/27/2023] Open
Abstract
INTRODUCTION Recently, we have reported the antitumor properties of a new family of synthetic merosesquiterpenes, among which meroxest is highlighted, since it has high activity and specificity for ER+ breast cancer cells. In this paper, we characterize allografts of ER+ E0771 mouse breast tumor cells in immunocompetent C57BL/6 mice, and also analyze the effect of meroxest on the prognosis of the disease. MATERIAL AND METHODS Twenty female C57BL/6 mice were injected with 106 E0771 cells. Once the tumors reached the appropriate size, the mice were divided into two groups, one control and another treated orally with 15 mg/kg of meroxest. After 20 days, tumor samples were taken for histopathological study and for determination of the expression of the prognostic markers Ki67 and vascular endothelial growth factor (VEGF) by immunofluorescence. RESULTS In sections stained with hematoxylin-eosin, we observed that tumors have a well-defined capsule enclosing E0771 tumor cells. The central area of tumors contains necrotic regions with leukocyte infiltration. Meroxest treatment significantly reduces tumor size (68%, p < 0.05), induces changes in its structure, decreases the degree of leukocyte infiltration, and significantly reduces the expression of Ki67 (33%, p < 0.05) and VEGF (82%, p < 0.05). CONCLUSIONS Meroxest improves the prognosis of mice since it reduces leukocyte infiltration, and decreases the expression of Ki67 and VEGF markers. Consequently, the merosesquiterpene could become a useful antiangiogenic drug in the treatment of breast cancer. These results encourage us to deepen the study of meroxest, in order to find more evidence that supports the convenience of its evaluation in a clinical study or trial.

Chen M, Zhan WW, Wang WP. Cystic breast lesions by conventional ultrasonography: sonographic subtype-pathologic correlation and BI-RADS Assessment. Arch Med Sci 2014; 10:76-83. [PMID: 24701218 PMCID: PMC3953978 DOI: 10.5114/aoms.2014.40734] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/15/2011] [Revised: 10/22/2011] [Accepted: 12/12/2011] [Indexed: 02/02/2023] Open
Abstract
INTRODUCTION Appropriate categorization is very important because the clinical management of each subtype of cystic breast lesions (CBLs) differs. The purpose was to evaluate the sonographic subtype-pathologic correlation, and to identify the effectiveness of the Breast Imaging Reporting and Data System (BI-RADS)-ultrasound (US) for differentiation of benign and malignant CBLs. MATERIAL AND METHODS A database from December 1, 2007 and November 30, 2009 was identified in the Department of Diagnostic Ultrasound, Rui Jin Hospital, School of Medicine, Shanghai Jiao Tong University, China. Those patients with palpable or clinical symptomatic breast masses were associated with a cystic component in lesions on breast US. All patients underwent a subsequent fine-needle/core-needle biopsy or surgical excision. The sonographic findings were analyzed according to the BI-RADS-US, and were categorized by two different methods of subtype categorization compared with the pathologic results. RESULTS Ninety-nine breast cystic lesions in 83 women were included, among whom 16 patients were identified with bilateral cystic lesions. The total malignancy rate of CBLs was 14.1% (95% confidence interval 7.3-21.0%). Among 99 CBLs, 14 malignant lesions were associated with sonographic appearances of complex cystic lesions, while the remaining subtypes were benign. Shape, margin, echo pattern, orientation, calcification, and vascularity were statistically significantly different between the benign and malignant lesions (p = 0.010, p = 0.004, p < 0.001, p < 0.001, p = 0.036, and p < 0.001, respectively) (degrees of freedom = 1). CONCLUSIONS By comparison of the two different methods of subtype categorization of CBLs, the appropriate 5-variety classification should be suggested. The BI-RADS-US was useful for differentiating benign from malignant cystic lesions.
