In the present study 18 novel imidazole-(benz)azole and imidazole-piperazine derivatives were synthesized in order to investigate their probable anticancer activity. The structures of the compounds were confirmed by IR, (1)H NMR and EI-MS spectral data. Cytotoxicity (MTT), analysis of DNA synthesis and detection of apoptotic DNA assays were applied to determine anticancer activity of the compounds against colon (HT-29) and breast (MCF-7) carcinoma cell lines. Most of the compounds, showed greater activity against HT-29 cells than MCF-7 cells. Some of them indicated considerable cytotoxicity against both of the carcinogenic cell lines. However, their inhibitory activity on DNA synthesis was relatively poor. Anticancer activity screening results revealed that 11, 12 and 13 were the most active compounds in the series. They exhibited significant cytotoxicity against both of the carcinogenic cell lines and caused DNA fragmentation of the HT-29 cells.

Objective: Lung cancer is the primary cause of cancer-related deaths globally. Protein kinase B (AKT) protein is associated with many pathways in non-small cell lung cancer (NSCLC), such as proliferation, migration, invasion, and apoptosis. Mushrooms have a long history of being used in traditional medicine to treat various diseases.

Currently, the synthesis of bioactive sulfonamides using amino acid as a starting reagent has become an area of research interest in organic chemistry. Over the years, an amine-sulfonyl chloride reaction has been adopted as a common step in traditional sulfonamide synthetic methods. However, recent developments have shown amino acids to be better precursors than amines in the synthesis of sulfonamides.

Reactive oxygen species (ROS)-mediated anticancer modalities, which disturb the redox balance of cancer cells through multi-pathway simulations, hold great promise for effective cancer management. Among these, cooperative physical and biochemical activation strategies have attracted increasing attention because of their spatiotemporal controllability, low toxicity, and high therapeutic efficacy. Herein, we demonstrate a nanogel complex as a multilevel ROS-producing system by integrating chloroperoxidase (CPO) into gold nanorod (AuNR)-based nanogels (ANGs) for cascade-amplifying photothermal-enzymatic synergistic tumor therapy.

Convectional drugs have failed to tackle the increasing public health challenge of Cancer and diabetes. Phytochemical conjugated nanoparticles are providing safer therapeutic alternatives to address this global challenge. Nanoparticles of nickel, iron and zinc are especially useful because of their magnetic properties, abilities to prevent the onset or slow the progression of these diseases.
