Abstract

Multinuclear complexes and methods for preparing them are provided. The discrete multinuclear complexes include a one or more transition metals and a radioisotope having the same coordination geometry as the transition metal. A bridging ligand is coordinated to the transition metal and the radioisotope to link the transition metal and the radioisotope and pendent ligands are coordinated to each of the transition metal and the radioisotope to stabilise the complex. The multinuclear complexes may include a radioisotope or radioelement that can be detected by medical equipment and may find use in therapy and/or the diagnosis of disease in patients.

Abstract

The present invention relates to a process for the microbial in-chain hydroxylation of C12 to C16 fatty acids, alcohols and alkanes at position ω-7, the process including the use of a microorganism expressing a cytochrome P450 monooxygenase CYP505E3 or related fungal cytochrome P450 monooxygenases sharing at least 70% amino acid identity in the production of a hydroxylated product or secondary product. The present invention further relates to a process for the preparation of lactones, esters and polymers by hydroxylation of the corresponding fatty acids, fatty alcohols and alkane precursors by a recombinant cytochrome P450 monooxygenase CYP505E3 or related fungal cytochrome P450 monooxygenases sharing at least 70% amino acid identity.

Abstract

The preparation of C-3 coupled biflavonoids and C-3 coupled biflavonoid analogs occurs from flavan-3-ones that are contacted with a compound having a nucleophilic aromatic moiety, in the presence of a Lewis acid where an intermediate compound is formed with a C-3 hydroxy group. A flavan-3-ol can be converted to a flavan-3-one as required. The intermediate compound is dehydrated to a flavene with a C-3-C-4 double bond. The flavene compound undergoes hydroboration-oxidation hydration to introduce a C-4 hydroxy group that can be oxidized to an oxo group or can be dihydroxylation to introduce hydroxy groups at the C-4 and C-3 carbons and dehydrated to a biflavonoid or biflavonoid analog having an oxo group at its C-4 carbon and substituted by the selected nucleophilic aromatic moiety on its C-3 carbon.

Abstract

A method and apparatus are provided for conducting a microbiological process on a bulk material in which a quantity of the bulk material is loaded onto a waterproof lining forming part of a bio cell with a heat transfer arrangement below the quantity of bulk material or within its volume, or both. The moisture content of the bulk material is controlled by periodic or intermittent distribution of water into the bulk material in order to promote microbiological activity within the bulk material by means of microbes that may be either naturally occurring within the bulk material or may be selected and introduced into the bulk material according to a desired result. A leachate recovery installation collects leachate draining from the bulk material. The temperature within the bulk material is monitored and the temperature controlled in order to elevate or decrease the temperature thereof to approach a target temperature associated with enhanced microbial activity of microbes present within the bulk material. The apparatus includes a controller having an electronic micro-processor with the controller having inputs for association with a temperature detector and a moisture detector. The preferred apparatus includes solar powered thermal and electrical energy units.

The present invention relates to the isolation and characterization of a protein responsible for the reduction of uranium (Vl) to uranium (IV) The present invention extends to the use of the isolated protein in the reduction of uranium (Vl) to uranium (IV) and further extends to a process for the bioremediation, or at least partial remediation, of a site contaminated with a source of U (Vl) According to a first aspect thereof, the present invention provides an isolated polypeptide derived from Thermus scotoductus strain SA-01 that is responsible for the reduction of uranium (Vl), in a source of uranium (Vl), to uranium (IV)1 wherein the polypeptide comprises the amino acid sequence of SEQ ID No: 1.

Abstract

The invention relates to methods for the preparation of an optically inactive and optically active compounds which are selected from the group consisting of C-3 coupled biflavonoids and C-3 coupled biflavonoid analogues from a starting material or intermediate which are respectively selected from the group consisting of optically inactive or optically active flavan-3-ols and optically active flavan-3-ones, the method comprising the steps of (a) providing an optically inactive or active compound having a fIavan-3-ol structure or a compound which is a flavan-3-one, (b) if a compound having a flavan-3-ol structure with a hydroxy group on the C-3 carbon is selected as starting material, converting the hydroxy group on the C-3 carbon of the compound having the flavan-3-ol structure to an oxo group to form a flavan-3-one of that compound, (c) providing a compound having a nucleophilic aromatic moiety, which compound is selected from the group of compounds having a nucleophilic aromatic moiety and which have flavonoid base structures and compounds having a nucleophilic aromatic moiety and which do not have a flavonoid base structure, (d) contacting the flavan-3-one provided by step (a) or obtained by step (b) with the compound containing the nucleophilic aromatic moiety in the presence of a Lewis acid; (e) forming a first intermediate compound wherein the oxo group on the C-3 carbon is converted to a hydroxy group by virtue of nucleophilic addition when the compound containing the nucleophilic aromatic moiety is contacted to the C-3 carbon of the flavan-3-one, (f) subjecting the first intermediate compound to dehydration so as to introduce a double bond between the C-3 carbon and C-4 carbon of the intermediate compound with the concomitant removal of the hydroxy group from the C-3 carbon to form an optically active flavene compound which is substituted by the nucleophilic aromatic moiety on the C-3 carbon, (g) optionally subjecting the resultant flavene compound to hydroboration-oxidation hydration thereby removing said double bond between the C-3 carbon and the C-4 carbon with the concomitant introduction of a hydroxy group at the C-4 carbon to form a second intermediate compound, (h) further optionally oxidizing the second intermediate compound of step (g) thereby converting the hydroxy group at the said C-4 carbon to an oxo group, thereby forming a biflavonoid or biflavonoid analogue which is substituted by the selected nucleophilic aromatic moiety on the C-3 carbon, (ι) further optionally, and alternatively to step (h), subjecting the resultant flavene compound of step (f) to OsC4 dihydroxylation thereby removing said double bond between the C-3 carbon and C-4 carbon with the concomitant introduction of a hydroxy group at the C-4 carbon and a hydroxy group at the C-3 carbon to form a third intermediate compound, and (j) subjecting the third intermediate compound to dehydration whereby the hydroxy group at the C-3 carbon is removed and a double bond is introduced between the C-3 carbon and C-4 carbon thereby forming an enol product and allowing such enol product to rearrange spontaneously to form a biflavonoid or biflavonoid analogue having an oxo group at its C-4 carbon and which is substituted by the selected nucleophilic aromatic moiety on its C-3 carbon.
