Background: Among all cancers, lung cancer has high mortality among patients in most of the countries in the world. Targeted delivery of anticancer drugs can significantly reduce the side effects and dramatically improve the effects of the treatment. Folate, a suitable ligand, can be modified to the surface of tumor-selective drug delivery systems because it can selectively bind to the folate receptor, which is highly expressed on the surface of lung tumor cells. Objective: This study aimed to construct a kind of folate-targeted topotecan liposomes for investigating their efficacy and mechanism of action in the treatment of lung cancer in preclinical models. Methods: We conjugated topotecan liposomes with folate, and the liposomes were characterized by particle size, entrapment efficiency, cytotoxicity to A549 cells and in vitro release profile. Technical evaluations were performed on lung cancer A549 cells and xenografted A549 cancer cells in female nude mice, and the pharmacokinetics of the drug were evaluated in female SD rats. Results: The folate-targeted topotecan liposomes were proven to show effectiveness in targeting lung tumors. The anti-tumor effects of these liposomes were demonstrated by the decreased tumor volume and improved therapeutic efficacy. The folate-targeted topotecan liposomes also lengthened the topotecan blood circulation time. Conclusion: The folate-targeted topotecan liposomes are effective drug delivery systems and can be easily modified with folate, enabling the targeted liposomes to deliver topotecan to lung cancer cells and kill them, which could be used as potential carriers for lung chemotherapy.

: Lung cancer is the second most common cancer and the primary cause of cancer-related death in both men and women worldwide. Due to diagnosis at an advanced stage, it is associated with high mortality in the majority of patients. At present, various treatment approaches are available such as chemotherapy, surgery, and radiotherapy. However, all these approaches usually cause serious side effects like degeneration of normal cells, bone marrow depression, alopecia, extensive vomiting, etc. To overcome the aforementioned problems, researchers have focused on the alternative therapeutic approach in which various natural compounds are reported, which possessed anti-lung cancer activity. Phytocompounds exhibit their anti-lung cancer activity via targeting various cell-signaling pathways, apoptosis, cell cycle arrest, and regulating antioxidant status and detoxification. Apart from the excellent anti-cancer activity, clinical administration of phytocompounds is confined because of their high lipophilicity and low bioavailability. Therefore, researchers show their concern in the development of a stable, safe, and effective approach of treatment with minimal side effects by the development of nanoparticle-based delivery of these phytocompounds to the target site. Targeted delivery of phytocompound through nanoparticles overcomes the aforementioned problems. In this article, the molecular mechanism of phytocompounds, their emerging combination therapy, and their nanoparticles-based delivery systems in the treatment of lung cancer have been discussed.

Abstract Targeted delivery and smart response of nanomedicine hold great promise to improve the therapeutic efficacy and alleviate the side effects of chemotherapy agents in cancer treatment. While a few research systems about organic nanomedicines with these properties have limited the development prospect of nanomedicines. In the present study, folic acid (FA) targeted delivery and GSH (glutathione) smart responsive nanomedicine was rationally designed for paclitaxel (PTX) delivery in the treatment of lung cancer. Compared with other stimuli responsive nanomedicines, this nano-carrier was not only sensitive to biologically relevant GSH for on demand drug release but also biodegradable into biocompatible by products after fulfilling its delivering task. The nanomedicine can firstly enter into tumor cells via FA and its receptor mediated endocytosis. After lysosomes escape, the PLGA (poly(lactic-co-glycolic acid) nanomedicine was triggered by the higher level of GSH and released its cargo in tumor microenvironment. In vitro and in vivo results revealed that the PLGA nanomedicine not only can inhibit the proliferation and promote the apoptosis of lung cancer cells greatly, but also possesses less toxic side effects when compared with free PTX. Therefore, the proposed drug delivery system demonstrates the encouraging potential for multifunctional nano-platform applicable to enhance the bioavailability and reduce the side effects of chemotherapy agents.

: Flavonoids have been shown to target aromatase, suppressing the transformed cells' proliferation and growth. Such experimental data further promoted the usage of flavonoids as an aromatase inhibitor and helps prevent cancer, specifically breast and lung cancer. Conversely, flavonoids have certain limitations like low absorption, potency, and some side effects in addition to their tremendous advantages. The pharmacokinetics and toxicity of flavonoids are now being addressed by using advanced nanotechnological approaches. This review discusses the comprehensive aromatase signaling pathway in normal and cancer cells. It also draws attention to how do flavonoids modulate aromatase signaling pathways. Also, different flavonoid groups inhibiting aromatase activities are discussed and listed in the Table comprising flavonoids group, cancer type, clinical trials, IC50, and the assay employed. Moreover, nanoparticles-mediated improvement in the pharmacokinetics and toxicity issues of flavonoids in targeting aromatase are also deliberated. In conclusion, flavonoids act as a potential anticancer agent via targeting aromatase. Besides, nanotechnological approaches are useful in addressing the pharmacokinetics and toxicity of flavonoids.

Lung cancer is a significant health problem worldwide. Unfortunately, current therapeutic strategies lack a sufficient level of specificity and can harm adjacent healthy cells. Consequently, to address the clinical need, novel approaches to improve treatment efficiency with minimal side effects are required. Nanotechnology can substantially contribute to the generation of differentiated products and improve patient outcomes. Evidence from previous research suggests that nanotechnology-based drug delivery systems could provide a promising platform for the targeted delivery of traditional chemotherapeutic drugs and novel small molecule therapeutic agents to treat lung cancer cells more effectively. This has also been found to improve the therapeutic index and reduce the required drug dose. Nanodrug delivery systems also provide precise control over drug release, resulting in reduced toxic side effects, controlled biodistribution, and accelerated effects or responses. This review highlights the most advanced and novel nanotechnology-based strategies, including targeted nanodrug delivery systems, stimuli-responsive nanoparticles, and bio-nanocarriers, which have recently been employed in preclinical and clinical investigations to overcome the current challenges in lung cancer treatments.
