Copper promoted desulfurization and C-N cross coupling reactions: Simple approach to the synthesis of substituted 2-aminobenzoxazoles and 2,5-disubstituted tetrazole amines

Copper-supported novel, facile and efficient methods for the synthesis of various 2-amino-benzoxazoles and 2,5-diphenyltetrazoleamines have been demonstrated. The reaction procedures are simple, with excellent substrate tolerance in good to high yields thus paving an excellent and useful way to establish a library of potentially active drug molecules. This methodology represents the first concept of copper-catalyst promoted domino C-N cross-coupling reaction towards the construction of 2-aminobenzoxazoles. In addition, we described report for the synthesis of 2,5-diaryltetrazoleamines using copper via inter molecular C-N cross-coupling reaction with aryl iodides. The proposed reaction mechanism involves copper based desulphurization/nucleophilic substitution and subsequent C-N cross-coupling reactions. We established numerous applications of this methodology for synthesizing diverse heterocyclic derivatives i.e. both electron rich and electron deficient systems.

Storage stability study of porcine hepatic and intestinal cytochrome P450 isoenzymes by use of a newly developed and fully validated highly sensitive HPLC-MS/MS method

Microsomes are an ideal medium to investigate cytochrome P450 (CYP450) enzyme-mediated drug metabolism. However, before microsomes are prepared, tissues can be stored for a long time. Studies about the stability of these enzymes in porcine hepatic and intestinal tissues upon storage are lacking. To be able to investigate CYP450 stability in microsomes prepared from these tissues, a highly sensitive and rapid HPLC-MS/MS method for the simultaneous determination of six CYP450 metabolites in incubation medium was developed and validated. The metabolites, paracetamol (CYP1A), 7-hydroxy-coumarin (CYP2A), 1-hydroxy-midazolam (CYP3A), 4-hydroxy-tolbutamide (CYP2C), dextrorphan (CYP2D), and 6-hydroxy-chlorzoxazone (CYP2E) were extracted with ethyl acetate at pH?1.0, followed by evaporation and separation on an Agilent Zorbax Eclipse Plus C18 column. The method was fully validated in a GLP-compliant laboratory according to European guidelines and was highly sensitive (LOQ = 0.25?2.5?ng/mL), selective, had good precision (RSD-within, 1.0?9.1%; RSD-between, 1.0?18.4%) and accuracy (within-run, 83.3?102%; between-run, 78.5?102%), and showed no relative signal suppression and enhancement. Consequently, this method was applied to study the stability of porcine hepatic and intestinal CYP450 isoenzymes when tissues were stored at ? 80?C. The results indicate that porcine CYP450 isoenzymes are stable in tissues at least up to 4?months when snap frozen and stored at ? 80?C. Moreover, the results indicate differences in porcine CYP450 stability compared to rat, rabbit, and fish CYP450, as observed by other research groups, hence stressing the importance to investigate the CYP450 stability of a specific species.

CYP2E1 phenotype in Mexican workers occupationally exposed to low levels of toluene

CYP2E1, an inducible enzyme present in different human tissues, metabolizes several potentially toxic substances including many volatile organic compounds (VOCs). One indirect way to monitor exposure to VOCs may be, therefore, the assessment of CYP2E1 activity in vivo using the chlorzoxazone (CHZ) test. Goal: To compare CYP2E1 activity in two groups of workers: one with a known occupational exposure to VOCs (exposed group) and the other employed in administrative tasks at two universities (control group) from the city of Leon, Guanajuato, Mexico. Material and methods: (1) Passive diffusion monitors were used to evaluate individual levels of exposure to toluene, benzene and ethylbenzene in 48 persons (24 tannery workers and 24 administrative controls) during a 8. h work shift; (2) after 12. h fasting 500. mg CHZ, a selective probe for assessing CYP2E1 activity, was orally administered and, after 2. h, a venous blood sample was collected for HPLC plasmatic quantitative determination of CHZ and its mean metabolite 6-hydroxychlorzoxazone. Results: Toluene mean exposure levels were higher in the exposed group (2.86 ¡À 2. ppm vs. 0.05 ¡À 0.005 ppm; p< 0.001). Also, in this group CYP2E1 activity was lower (p< 0.05) and it decreased as the accumulated months of labor exposure increased (negative correlation, p< 0.05). These results are in line with previous findings obtained from shoemakers exposed to various solvents but, interestingly, they are partly in contrast with those of another study in printers. Conclusion: In spite of the relatively low levels of toluene exposure found for tannery workers, an effect on CYP2E1 activity was evident. Although the mechanism of this interaction is still unknown, the decrease in CYP2E1 activity per se might represent a health risk, considering that these workers may be less protected against other CYP2E1 substrates present in the labor setting or derived from an intentional exposure.
