3D cell culture can be successfully used as an alternative to laboratory animals, and as a cost effective and time-saving tissue culture technique, which also reduces the trial period for drug testing.

Silver nanoparticles (AgNP) emerged as a promising reagent for cancer therapy with oxidative stress implicated in the toxicity. Meanwhile, studies reported cold atmospheric plasma (CAP) generation of reactive oxygen and nitrogen species has selectivity towards cancer cells. Gold nanoparticles display synergistic cytotoxicity when combined with CAP against cancer cells but there is a paucity of information using AgNP, prompting to investigate the combined effects of CAP using dielectric barrier discharge system (voltage of 75 kV, current is 62.5 mA, duty cycle of 7.5kVA and input frequency of 50–60Hz) and 10 nm PVA-coated AgNP using U373MG Glioblastoma Multiforme cells.

4-Aryl-4H-Chromene derivatives have been previously shown to exhibit anti-proliferative, apoptotic and anti-angiogenic activity in a variety of tumor models in vitro and in vivo generally via activation of caspases through inhibition of tubulin polymerisation. We have previously identified by Virtual Screening (VS) a 4-aryl-4H-chromene scaffold, of which two examples were shown to bind Estrogen Receptor α and β with low nanomolar affinity and <20-fold selectivity for α over β and low micromolar anti-proliferative activity in the MCF-7 cell line. Thus, using the 4-aryl-4H-chromene scaffold as a starting point, a series of compounds with a range of basic arylethers at C-4 and modifications at the C3-ester substituent of the benzopyran ring were synthesised, producing some potent ER antagonists in the MCF-7 cell line which were highly selective for ERα (compound 35; 350-fold selectivity) or ERβ (compound 42; 170-fold selectivity).

Oral cancer is one of the most common malignancies worldwide, with over 350,000 to 400,000 new cases reported each year. Early detection, followed by appropriate treatment, can increase cure rates to 80 or 90%, and greatly improve the quality of life by minimising extensive, debilitating treatments. Usually, the clinical diagnosis of most head and neck neoplasms, including oral cancer, is performed through time-consuming and invasive biopsies followed by histological examination of the excised tissue and may present psychological trauma and risk of infection to patients. In addition, histological grading can be subjective, as it is based on subtle morphological changes. …
