<p>Dechlorane 604 is a chemical that is used as an additive in some plastics. It has been detected in the environment and human populations, but the low detection limits make it difficult to determine if Dechlorane 604 is endocrine disruptor. Animal experiments have shown that Dechlorane 604 can bind to hormone receptors, but there are no studies on its effects on humans. There are database records for Dechlorane 604 and its metabolites, but these do not provide information on their toxicity. The analytical method for detecting Dechlorane 604 has been developed and validated by GC/MS-ECD analysis of ethane extracts from soil samples. This method is based on dispersive microextraction (SPME) with gas chromatography/mass spectrometry (GC/MS). In vitro studies have examined the effects of Dechlorane 604 on the elongatus nematode and dry weight measurements show that this chemical alters metabolism by altering fatty acid composition.</p>

Native Melan-A (26-35) decapeptide derives from the melanocyte lineage-specific protein Melan-A/MART-1, which is expressed in almost 75-100% of primary and metastatic melanomas. The region 26-35 of Melan-A protein acts as an antigenic peptide that is recognized by CD8+ tumor-reactive cytolytic T lymphocytes (CTLs) for designing antigen-specific cancer vaccines1. It has been shown that CD8+ Melan-A-specific CTLs isolated from melanoma patients efficiently lyse the Melan-A-expressing HLA-A*0201+ melanoma cell line. However, CTLs preferentially recognize the Melan-A (26-35) peptide as compared with the Melan-A (27-35) peptide. Moreover, the Melan-A (26-35) A27L analog (ELAGIGILTV) has a higher binding affinity to HLA-A*0201 than the native Melan-A (26-35) peptide (EAAGIGILTV), and consequently displays more potent antigenicity and immunogenicity. It has been reported that the concentration of Melan-A (26-35) A27L analog required to obtain 50% of maximal antigenic activity (EC50) is 0.01nM, whereas that of the native Melan-A (26-35) peptide is 0.25nM1. Therefore, the relative activity of Melan-A (26-35) A27L analog is 25 fold higher than that of the native Melan-A (26-35) peptide. Furthermore, functional competition assay has shown that the concentration of Melan-A (26-35) A27L analog required to achieve 50% inhibition (IC50) of tumor lysis is 2nM, which is 10 fold lower than that of the native Melan-A (26-35) peptide. Regarding peptide stability in human serum, the half-lifes (t1/2) of the native Melan-A (26-35) peptide and the A27L analog are quite similar (45 and 40min, respectively) as measured by HPLC-ESI-MS, but much higher than that of the Melan-A (27-35) nonapeptide (5min).
