[PMID: 38865742 DOI: 10.1016/j.ejmech.2024.116562] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2024] [Revised: 05/10/2024] [Accepted: 05/31/2024] [Indexed: 06/14/2024]
Abstract
As a molecular chaperone, heat shock protein 90 (HSP90) plays important roles in the folding, stabilization, activation, and degradation of over 500 client proteins, and is extensively involved in cell signaling, proliferation, and survival. Thus, it has emerged as an important target in a variety of diseases, including cancer, neurodegenerative diseases, and viral infections. Therefore, targeted inhibition of HSP90 provides a valuable and promising therapeutic strategy for the treatment of HSP90-related diseases. This review aims to systematically summarize the progress of research on HSP90 inhibitors in the last five years, focusing on their structural features, design strategies, and biological activities. It will refer to the natural products and their derivatives (including novobiocin derivatives, deguelin derivatives, quinone derivatives, and terpenoid derivatives), and to synthetic small molecules (including resorcinol derivatives, pyrazoles derivatives, triazole derivatives, pyrimidine derivatives, benzamide derivatives, benzothiazole derivatives, and benzofuran derivatives). In addition, the major HSP90 small-molecule inhibitors that have moved into clinical trials to date are also presented here.

Pharmaceuticals (Basel) 2024; 17:94. [PMID: 38256926 PMCID: PMC10818515 DOI: 10.3390/ph17010094] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Revised: 12/31/2023] [Accepted: 01/05/2024] [Indexed: 01/24/2024] Open
Abstract
Matrine (MAT), a natural Chinese herbal medicine, has a unique advantage in the treatment of various chronic diseases. However, its low melting point, low bioavailability, and high dosage restrict its subsequent development into new drugs. In this study, three kinds of MAT salts, namely, MAT-2,5-dihydroxybenzoic acid (MAT-25DHB), MAT-2,6-dihydroxybenzoic acid (MAT-26DHB), and MAT-salicylic acid-hydrate (MAT-SAL-H2O), were designed and synthesized to improve the drugability of MAT. The three salts were characterized by using various analytical techniques, including single-crystal X-ray diffractometry, powder X-ray diffractometry, differential scanning calorimetry, thermogravimetry, and infrared spectroscopy. The results of the thermal stability evaluation showed that the formation of salts improved the stability of MAT; MAT-25DHB is the most stable salt reported at present. The results of aqueous solubility showed that the solubility of MAT-25DHB was higher than that of MAT, while that of MAT-26DHB and MAT-SAL-H2O were less. Given that the MAT-25DHB salt further improved the solubility of MAT, it is expected to be subjected to further research as an optimized salt. Lattice energy and solvation free energy are important factors affecting the solubility of salts; the reasons for the changes of solubility and stability of three kinds of salts are explained by calculating them.

Abstract
Porcine reproductive and respiratory syndrome (PRRS) seriously endangers the sustainable development of the pig industry. Our previous studies have shown that matrine can resist porcine reproductive and respiratory syndrome virus (PRRSV) infection. This study aimed to explore the anti-PRRSV targets of matrine in Marc-145 cells. Biotin-labeled matrine 1 and 2 were used as probes. MTT assay was used to determine the maximum non-cytotoxic concentration (MNTC) of each probe in Marc-145 cells. The anti-PRRSV activity of each probe was evaluated via MTT, qPCR and Western blot, and its anti-inflammatory activity was evaluated via qPCR and Western blot. The targets of matrine in Marc-145 cells were searched using activity-based protein profiling (ABPP), and compared with the targets predicted via network pharmacology for screening the potential targets of matrine against PRRSV. The protein-protein interaction networks (PPI) of potential targets were constructed using a network database and GO/KEGG enrichment analysis was performed. ACAT1, ALB, HMOX1, HSPA8, HSP90AB1, PARP1 and STAT1 were identified as potential targets of matrine, and their functions were related to antiviral capacity and immunity. Matrine may play an anti-PRRSV role by directly acting on ACAT1, ALB, HMOX1, HSPA8, HSP90AB1, PARP1 and STAT1.

Exploration of anti-leukemic effect of soft coral-derived 13-acetoxysarcocrassolide: Induction of apoptosis via oxidative stress as a potent inhibitor of heat shock protein 90 and topoisomerase II. Kaohsiung J Med Sci 2023. [PMID: 37052190 DOI: 10.1002/kjm2.12678] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2022] [Revised: 02/21/2023] [Accepted: 03/01/2023] [Indexed: 04/14/2023] Open
Abstract
13-Acetoxysarcocrassolide (13-AC) is a marine cembranoid derived from the aquaculture soft coral of Lobophytum crassum. The cytotoxic effect of 13-AC against leukemia cells was previously reported but its mechanism of action is still unexplored. In the current study, we showed that 13-AC induced apoptosis of human acute lymphoblastic leukemia Molt4 cells, as evidenced by the cleavage of PARP and caspases, phosphatidylserine externalization, as well as the disruption of mitochondrial membrane potential. The use of N-acetylcysteine (NAC), a reactive oxygen species (ROS) scavenger, attenuated the cytotoxic effect induced by 13-AC. Molecular docking and thermal shift assay indicated that the cytotoxic mechanism of action of 13-AC involved the inhibition of heat shock protein 90 (Hsp 90) activity by eliciting the level of Hsp 70 and topoisomerase IIα in Molt4 cells. 13-AC also exhibited potent antitumor activity by reducing the tumor volume (48.3%) and weight (72.5%) in the in vivo Molt4 xenograft mice model. Our findings suggested that the marine cembranoid, 13-AC, acted as a dual inhibitor of Hsp 90 and topoisomerase IIα, exerting more potent apoptotic activity via the enhancement of ROS generation.

Kaohsiung J Med Sci 2023; 39:501-510.

Abstract
Atopic dermatitis (AD) is a common inflammatory skin disease. Matrine is the main component of the traditional Chinese medicine Sophora flavescens, and it poses good therapeutic effects on inflammatory diseases. This study aimed to explore the pharmacological effects of matrine on AD and its underlying mechanism. An AD mouse model and inflamed human epidermal keratinocyte cells (HaCaT) cells were established. Histopathological aspects were examined using hematoxylin and eosin staining, toluidine blue staining, and immunohistochemistry. The mRNA and protein expressions were assessed using quantitative real-time polymerase chain reaction and Western blot, respectively. The secretions of cytokines and chemokines were examined by enzyme-linked immunosorbent assay. Flow cytometry was carried out to analyze the proportions of T-helper (Th) 1 and Th2 cells. Herein, our results displayed that matrine diminished AD symptoms and decreased heat shock protein 90 (Hsp90) expression. Matrine decreased the Th2 cytokine levels in the ear tissues and serum, and it also significantly repressed inflammatory cytokines (thymus activation regulated chemokine and interleukin-6) secretions by repressing the Hsp90/NF-κB signaling axis in inflamed HaCaT cells. Furthermore, matrine inhibited Th2 differentiation of CD4+ T cells when co-cultured with inflamed HaCaT cells. Matrine can regulate the Th1/Th2 inflammatory response by inhibiting the Hsp90/NF-κB signaling axis to alleviate AD. Therefore, it may be a candidate for AD treatment.

Novel matrinic acid derivatives bearing 2-anilinothiazole structure for non-small cell lung cancer treatment with improved Hsp90 targeting effect. Drug Dev Res 2022; 83:1434-1454. [PMID: 35841121 DOI: 10.1002/ddr.21974] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2022] [Revised: 06/03/2022] [Accepted: 06/22/2022] [Indexed: 11/09/2022]
Abstract
Involved in mediating the folding and maturation of more than 300 client proteins, many of which are oncoproteins, Hsp90 has emerged as a promising drug target for cancer therapy. In particular, inhibiting Hsp90 plays a vital role in the treatment of non-small cell lung cancer. Owing to undesirable outcomes of Hsp90 inhibitors in clinical trials, a series of matrinic acid compounds bearing 2-anilinothiazole moiety were designed based on the structural features allocation shared among Hsp90 inhibitors within the ATP-binding pocket. Most of the compounds showed potent anticancer activities validated by MTT assay. Among them, the most potent compound C4 (IC50 < 10 μM against four cell lines) was chosen for further mechanism study. Notably, C4 showed a better safety profile than 17AAG with a higher SI value. Thermal shift assay data indicated C4 exhibited a strong binding affinity with Hsp90 (-18.85 ± 0.56°C) comparable to radicicol. Mechanism studies verified that C4 significantly inhibited proliferation and migration activities of A549 cells. Besides, C4 can induce a prolonged G1-phase and cell apoptosis. Western blot analysis results indicated C4 could moderately suppress Hsp90 and upregulate Hsp70 expression. Furthermore, the downregulated trend of the client proteins of Hsp90, such as β-Catenin and Bcl-2, were consistent with the cellular effect of C4, suggesting that C4 could exert anticancer activity via targeting Hsp90. In the xenograft model in vivo, C4 effectively inhibited lung cancer growth without obvious side effects. Collectively, C4 could be a promising therapeutic agent for lung cancer and the novel scaffold provided new insights into the design of Hsp90 inhibitors.

Abstract
Aim
Gastric cancer is a highly prevalent public health problem with high morbidity and mortality. İt’s primary treatment is surgery. Recently studies involving biological parameters and genetics in gastric cancer are emerging but with many blind spots
Our study aims to investigate the clinicopathological and prognostic significance of heat shock proteins (HSP90) expression in patients with resectable gastric cancer.
Methods
One center retrospective clinical study conducted at general surgery clinic at in a local training and research hospital. Our study involves 54 patients who had curative surgery for gastric cancer between 2011 and 2014.
Results
Pathological specimens fixed in formaline and parafin were re-evaluated with HSP90 stain and expression of HSP90 was evaluated. It was seen that only 39 (72.2%) patients had HSP90 expression. Seventeen (31.5%) of these had mild, 13 (24.1%) had moderate, 9 (10.5%) severe expression.
Conclusion
There are various reports in literature about HSP90 expression in gastric cancer which state that it is a prognosticator while some studies say it is not. There are a number of shortcomings of our study as we did not include metastatic tumors, study involves only our patients, low number of patients, single pathologist involvement. This is the first study done in our population on this subject. Further studies could be done to delineate this particular relationship in an effort to possibly identify novel treatments in gastric cancer.
