[PMID: 37568716 PMCID: PMC10417465 DOI: 10.3390/cancers15153900] [Citation(s) in RCA: 21] [Impact Index Per Article: 21.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Revised: 07/21/2023] [Accepted: 07/26/2023] [Indexed: 08/13/2023] Open
Abstract
Cancer is a global health burden responsible for an exponentially growing number of incidences and mortalities, regardless of the significant advances in its treatment. The identification of the hallmarks of cancer is a major milestone in understanding the mechanisms that drive cancer initiation, development, and progression. In the past, the hallmarks of cancer have been targeted to effectively treat various types of cancers. These conventional cancer drugs have shown significant therapeutic efficacy but continue to impose unfavorable side effects on patients. Naturally derived compounds are being tested in the search for alternative anti-cancer drugs. Steroidal saponins are a group of naturally occurring compounds that primarily exist as secondary metabolites in plant species. Recent studies have suggested that steroidal saponins possess significant anti-cancer capabilities. This review aims to summarize the recent findings on steroidal saponins as inhibitors of the hallmarks of cancer and covers key studies published between the years 2014 and 2024. It is reported that steroidal saponins effectively inhibit the hallmarks of cancer, but poor bioavailability and insufficient preclinical studies limit their utilization.

Wang Y, Wang S, Xu J, Wang Y, Xiang L, He X. Total steroidal saponins from black nightshade (Solanum nigrum L.) overcome tumor multidrug resistance by inducing autophagy-mediated cell death in vivo and in vitro. Phytother Res 2023. [PMID: 36877123 DOI: 10.1002/ptr.7796] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Revised: 01/18/2023] [Accepted: 02/11/2023] [Indexed: 03/07/2023]
Abstract
Multiple drug resistance (MDR) often occurs after prolonged chemotherapy, leading to refractory tumors and cancer recurrence. In this study, we demonstrated that the total steroidal saponins from Solanum nigrum L. (SN) had broad-spectrum cytotoxic activity against various human leukemia cancer cell lines, especially in adriamycin (ADR)-sensitive and resistant K562 cell lines. Moreover, SN could effectively inhibit the expression of ABC transporter in K562/ADR cells in vivo and in vitro. In vivo, by establishing K562/ADR xenograft tumor model, we demonstrated that SN might overcome drug resistance and inhibit the proliferation of tumors by regulating autophagy. In vitro, the increased LC3 puncta, the expression of LC3-II and Beclin-1, and the decreased expression of p62/SQSTM1 in SN-treated K562/ADR and K562 cells demonstrated autophagy induced by SN. Moreover, using the autophagy inhibitors or transfecting the ATG5 shRNA, we confirmed that autophagy induced by SN was a key factor in overcoming MDR thereby promoting cell death in K562/ADR cells. More importantly, SN-induced autophagy through the mTOR signaling pathway to overcome drug resistance and ultimately induced autophagy-mediated cell death in K562/ADR cells. Taken together, our findings suggest that SN has the potential to treat multidrug-resistant leukemia.

Abstract
The berries of black nightshade (Solanum nigrum L.) are consumed as a favorite fruit in some regions and have been reported to possess a range of biological activities. Previous studies have found that the steroidal saponins from the berries of S. nigrum (SN) showed potential antileukemic activity, although the underlying mechanism remains to be revealed. This study investigated the effects and mechanisms of SN in combination with adriamycin to reverse leukemia multidrug resistance in vivo and in vitro. The results indicated that the combination of SN and adriamycin displayed enhanced suppression ability both in vitro and in vivo by the modulation of drug efflux proteins. Further study revealed that SN and adriamycin co-treatment induced cell apoptosis in K562/ADR cells through caspase pathways and autophagy through the PI3K/Akt/mTOR and MAPK signaling pathway. This study provides a new prospect of the berries of black nightshade in multidrug resistance therapy of cancer.

[PMID: 36269390 DOI: 10.1007/s00432-022-04387-2] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2022] [Accepted: 09/27/2022] [Indexed: 02/03/2023]
Abstract
Multi-drug resistance has shown to be one of the leading threats faced currently in many chemotherapeutic agents. Permeability glycoprotein (P-gp) is an efflux transporter in membrane, an integral part of ATP-binding cassette (ABC) transporters widely distributed in the body for cellular uptake. It is present enormously in cancerous cells and is in charge of generating transporter mediated resistance to treatments of tumorous cells in addition to blocking the entry of chemotherapeutic drugs into the cell. Natural P-gp inhibitors are derived from natural plant sources possessing basic structures like alkaloids, flavonoids, phenolics, terpenoids, saponins, sapogenins, sterols, coumarins and miscellaneous structures acting on P-gp substrate for inhibition of multi-drug resistance via inhibiting the efflux pump. They do not depict their action on the healthy cells and thus it is proven to be more effective and less toxic than synthetic P-gp inhibitor leading to enhancement in bioavailability of chemotherapeutic drugs. The significant objective of the present review is surfing through the impact of natural P-gp inhibitors having basic structures derived from the plant sources and how it inhibits the resistance of chemotherapeutic drugs together with how well it delivers chemotherapy medicines.
