One of the most difficult diseases to treat in people is cancer, and its mortality rate has recently increased significantly. Nanoparticles are used in the rapidly developing field of cancer nanomedicine to diagnose and as well treat cancer. The often-systemic effects with conventional therapy have now been minimized by the ability of nanoparticles to release normally considered insoluble medicines to tumor locations both far and near. Due to their strong qualities and effects, which include biocompatibility, biosafety, biodegradability, synergistic and autologous therapeutic effects, biologically-based nanomaterials have drawn great interests with regards to cancer therapy. It has been extensively discussed and discovered that nucleic acid, polysaccharides, polyphenol or phenolics, proteins (also peptide), cell and subcellular fractions, as well as lipid are bioactive substances. The utilization of these biologically-active materials in nano-formulation is promising toward efficient treatment of cancer through by different oncological therapeutic strategies. As a result of their structural characterizations, adaptable characteristics, anti-tumor processes, and biological performances, these bioactive compounds have been specifically used as examples of the functions of composite nanosystems.

The brain has natural antioxidant defense systems, functioning through enzymes such as superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase, which neutralize reactive oxygen species (ROS). Once these defense systems are overwhelmed by poisoning, oxidative damage can occur in the brain. In this study, hydrogen peroxide (H2O2) was used to induce oxidative stress. Ascorbic acid grafted to silica nanoparticles (SiO2-NPs@AA) was used as a therapeutic strategy aimed to reduce ROS levels and enhancing antioxidant defenses. The SiO2-NPs@AA were synthesized and characterized, showing efficient functionalization with ascorbic acid. The in-vitro, antioxidant assays revealed that SiO2-NPs@AA exhibited significant radical scavenging activity (DPPH and hydroxyl radicals) and high iron-chelating ability with enhanced stability compared to free ascorbic acid. Moreover, the in-vivo study demonstrated that SiO2-NPs@AA mitigated H2O2-induced effects in key enzymes, including superoxide dismutase, catalase, glutathione (GSH), and restore acetylcholinesterase (AChE) levels. Notably, malondialdehyde (MDA) levels, a marker of lipid peroxidation, were significantly reestablished in the frontal cortex and hippocampus following SiO2-NPs@AA. Overall, the study revealed that SiO2-NPs@AA corrected effectively nitric oxide (NO) and monoamine oxidase activities, which confirm their role to preserve neuronal function and mitigate neurotoxicity.

The increasing incidence of Human Papillomavirus (HPV)-related head and neck cancers, particularly oropharyngeal squamous cell carcinomas, highlights the need for advanced therapeutic options beyond the traditional modalities of surgery, radiation, and chemotherapy, which often lead to significant morbidity and lack specificity in targeting the molecular pathogenesis of the disease. Proteolysis Targeting Chimeras (PROTACs) present a novel therapeutic strategy, leveraging the ubiquitin-proteasome system to specifically degrade the oncogenic HPV proteins E6 and E7. This targeted approach not only potentially reduces the side effects associated with conventional treatments but also directly interrupts the cancer-promoting activities of these proteins, offering a promising avenue for more effective and less invasive treatment of HPV-associated malignancies.

The weed Martynia annua traditionally known as Kakanasika is annual herbaceous plant known for its multiple medicinal properties such as anthelmintic, analgesic, antipyretic, antibacterial, anti-convulsant, anti-fertility, antinociceptive, antioxidant, CNS depressant and wound healing activity. The aqueous root extract of M. annua was subjected to qualitative analysis, revealing the presence of terpeniods, indicative of its rich phytochemicals composition. Utilizing a green synthesis approach, silver nanoparticles (AgNPs) were successfully synthesized from the plant extract. Characterization through UV-Visible spectroscopy, FTIR, DLS, and SEM/EDX confirmed the formation of AgNPs with polygonal morphology and an average size of 64 nm, with the PDI of 0.385. Additionally, the AgNPs demonstrated moderate stability, evidenced by a zeta potential of −21.6 mV. Evaluation of the synthesized AgNPs focused on their anti-diabetic potential. The green synthesized R-AgNPs were potent antioxidant agents. They exhibited significant inhibition of alpha amylase, a pivotal enzyme in carbohydrate metabolism, suggesting their efficacy as anti-diabetic agents. Moreover, the AgNPs enhanced glucose uptake by yeast cells, indicating their promising therapeutic role in managing diabetes mellitus. This study highlights the pharmacological importance of M.annua, particularly its aqueous root extract, in the eco-friendly synthesis of AgNPs with potential therapeutic implications. Further investigation into the mechanism of action and clinical efficacy of these AgNPs in diabetes management is warranted.

Integrating nanomedicines for targeted cancer treatment and pursuing medicinally valuable components from nature are crucial for sustainable, potent alternatives to synthetic drugs in combating fatal diseases like cancer. Hence, a green synthesis of nickel oxide (NiO NPs) and zinc oxide nanoparticles (ZnO NPs) has been carried out by using the leaf extract of medicinally important plant Abutilonindicum. This sustainable approach to medical developments not only reduces the environmental effect of standard synthesis methods and offers new options for novel cancer therapeutics, but it also advances public health by using natural resources in a sustainable manner.
Methods
The synthesized nanoparticles were characterized by employing spectro-analytical techniques like UV–vis, FT-IR, SEM and powder XRD. Synthesized nanparticles were evaluated in the human cervical cancer cells (HeLa).
Results
Ni-O stretching vibrations were observed at 402 cm−1, whereas that of Zn-O stretching was observed at 409 cm−1in the FT-IR spectrum, confirming the formation of nanoparticles. The XRD pattern revealed the crystallite size range of 1.35–2.84 nm for NiO NPs and 7.71–56.80 nm for ZnO NPs. The morphology of the nanoparticles, as indicated by the SEM images, was rod-like for NiO NPs and rock-shaped for ZnO NPs. Further, the cancer cell growth inhibition activity of the nanoparticles was examined by MTT assay against human cervical cancer cells (HeLa) proliferation and compared with cisplatin. MTT assay elucidated the significant anticancer efficacy of the synthesized nanoparticles, showcasing low IC50 values of 29±0.5 µg/ml for NiO NPs and 32±0.7 µg/ml for ZnO NPs. Furthermore, the anticancer activity of the NiO NPs was investigated using the Trypan blue dye exclusion technique, emphasizing the pronounced cytotoxic impact of NiO NPs on cancer cell viability. The outcomes underscore the notable anticancer properties of plant extract mediated metal nanoparticles as promising contenders for advancing cancer treatment modalities.
