    摘要: A method for detecting the presence of an oxygenated compound which is produced when a substrate is reacted with an oxygenase for the substrate. The method involves reacting a coupling enzyme with the oxygenated compound to form a polymeric oxygenated compound which is fluorescent or luminescent. Measurement of the fluorescence or luminescence of the polymeric oxygenated compound provides indirect detection of the oxygenated compound produced by reaction of the oxygenase with the substrate. The method is carried out in a whole cell environment wherein the cell is transformed to express both the oxygenase being screened and the coupling enzyme. The method can be used to measure the activity of monooxygenases and dioxygenases on aromatic substrates. The method is amenable to large scale screening of enzyme mutants to isolate those with maximum oxygenase activity.

    摘要: Reactive sites on a substrate molecule, typically a drug, may be identified and the relative rates of their metabolism by the CYP enzymes may be determined. Determining these relative rates is an important factor in determining the absolute rate of metabolism of the individual sites and the substrate molecule as a whole. This information is also a critical factor in determining whether and how the substrate can be redesigned to improve its ADME/PK properties. In this regard, it is particularly important to know how the relative rates compare to the rate of a non-metabolic side reaction (branch pathway) such as water generation and regeneration of the substrate.

    摘要: Novel metabolites and enzymes involved in skatole metabolism are disclosed. The novel metabolites are 3-OH-3-methylindolenine (HMI); 3-methyloxindole (3MOI); indole-3-carbinol (I-3C); and 2-aminoacetophenone (2-AM). Measuring levels of these metabolites in a pig may be useful in identifying the pig's ability to metabolize skatole and its susceptibility to boar taint. The novel enzymes involved in skatole metabolism are aldehyde oxidase and CYP2A6. Enhancing the activity of these enzymes may be useful in enhancing skatole metabolism and reducing boar taint. The identification of the enzyme also allows the development of screening assays for substances that interact with these enzymes and skatole metabolism. Pigs having high levels of these enzymes may be selected and bred to produce pigs that have a lower incidence of boar taint.

    摘要: Wound healing is impaired in many diabetics, who suffer increased risk of chronic foot ulceration and amputation. Diabetic patients with poor healing ability were found to possess significantly lower fasting urinary nitrate levels than diabetic patients with normal healing ability or non-diabetic controls, implicating decreased endogenous nitric oxide activity as the mediator of diabetes-impaired wound healing. Methods and kits are provided for predicting the wound healing ability of diabetic patients based on the levels of nitric oxide related products such as nitrate or nitrite in urine or other specimens. Methods are also provided for treating non-wound healing diabetics and monitoring diabetic ulcer treatment.

    摘要: A method and apparatus for determining the enzyme or enzymes in the human body which metabolize a particular drug. Microsomes are obtained from each of several donors. The microsome for one donor is reacted with a test drug and the quantity of metabolites produced is determined. The microsomes are similarly each reacted with the test drug and the quantity of metabolites produced for each microsome is determined to generate drug metabolism data. The drug metabolism data obtained is compared to reference data which indicates the activity of a select number of major enzymes in each of the donors. The reference data for each enzyme is separately tabulated. The enzyme responsible for the metabolism of the test drug is identified when the metabolism data correlates with the tabulated reference data for that enzyme.
