Identification and Characterization of AES-135, a Hydroxamic Acid-Based HDAC Inhibitor That Prolongs Survival in an Orthotopic Mouse Model of Pancreatic Cancer

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive, incurable cancer with a 20% 1 year survival rate. While standard-of-care therapy can prolong life in a small fraction of cases, PDAC is inherently resistant to current treatments, and novel therapies are urgently required. Histone deacetylase (HDAC) inhibitors are effective in killing pancreatic cancer cells in in vitro PDAC studies, and although there are a few clinical studies investigating combination therapy including HDAC inhibitors, no HDAC drug or combination therapy with an HDAC drug has been approved for the treatment of PDAC. We developed an inhibitor of HDACs, AES-135, that exhibits nanomolar inhibitory activity against HDAC3, HDAC6, and HDAC11 in biochemical assays. In a three-dimensional coculture model, AES-135 kills low-passage patient-derived tumor spheroids selectively over surrounding cancer-associated fibroblasts and has excellent pharmacokinetic properties in vivo. In an orthotopic murine model of pancreatic cancer, AES-135 prolongs survival significantly, therefore representing a candidate for further preclinical testing

Chemical sensors for electronic nose systems

Abstract. Chemical sensors have been widely used for the analysis of volatile organic compounds. Employing chemical sensors in an array format with pattern re-cognition provides a higher degree of selectivity and reversibility leading to an extensive range of applica-tions. When such systems are used for odour analysis they are termed ‘electronic noses’. Application of elec-tronic noses ranges from the food industry, medical industry to environmental monitoring and process con-trol. Many types of different gas sensors have been employed in the array. These include conducting poly-mers, metal oxide semiconductors, piezoelectric, opti-cal fluorescence and amperometric gas sensors The transducer principle of these sensors is varied and is discussed in detail within this review.
