Our analysis indicates that compounds binding their primary targets

with higher entropy contributions tend to hit more off-targets compared with those ligands that demonstrated enthalpy-driven binding.”
“Background/Aims: Liver is the most common site of metastases in uveal melanoma. Hepatic arterial infusion of cytotoxic agents may be an effective method FDA-approved Drug Library in vitro of controlling the disease in these patients.\n\nMethodology: A retrospective analysis of 10 patients with hepatic metastases of uveal melanoma treated with hepatic arterial infusion (HAT) of the combination of cisplatin, vinblastine and dacarbazine was performed.\n\nResults: Two patients had an objective response, 4 patients had stable disease and 4 patients

had progressive disease. The median survival from the start of therapy was 16 (range 5 – 69) months. HAI of second line agents was of limited effectiveness. All patients with progressive disease died within one year while all patients with clinical benefit response (objective response or stable disease) survived more than one year.\n\nConclusions: Present data demonstrate, in agreement with the literature, the effectiveness of HAI in the treatment of uveal melanoma metastatic to the liver. The HAI of combination of cisplatin, vinblastine and dacarbazine seems to have similar efficacy as other HAI regimens.”
“EGFR is frequently overexpressed in head and neck squamous cell cancer (HNSCC). Cetuximab is a monoclonal antibody designed to interact with EGFR, block AZD7762 in vitro its activation, reduce the downstream signaling pathways and

induce EGFR internalization. This study aims to investigate the role of the EGFR signaling pathway and EGFR internalization in a cetuximab-resistant cell line and to propose CT99021 in vivo a new therapeutic strategy to optimize treatment of HNSCC. The HNSCC cell line, CAL33 was sensitive to gefitinib but resistant to cetuximab. Cetuximab induces an unexpected EGFR phosphorylation in CAL33 cells similarly to EGF but this EGFR activation does not trigger EGFR internalization/degradation, the process currently implicated in the response to cetuximab. Cetuximab inhibits ERK and AKT phosphorylation in cetuximab-sensitive A431 cells, whereas the level of AKT phosphorylation is unmodified in cetuximab-resistant cells. Interestingly, CAL33 cells harbor a PIK3CA mutation. The treatment of CAL33 cells with PI3K inhibitor and cetuximab restores the inhibition of AKT phosphorylation and induces growth inhibition. Our results indicate that EGFR internalization is impaired by cetuximab treatment in CAL33 cells and that the AKT pathway is a central element in cetuximab resistance. The combination of cetuximab with a PI3K inhibitor could be a good therapeutic option in PIK3CA-mutated HNSCC.”
