In a preferred embodiment, the optical transmission means comprises a pair of substantially parallel elongate light guides each light guide having a distal end provided with a reflective surface inclined at 45° to the direction of light transmission along the light guides, the reflective surfaces of the light guides being opposed such that light emitted from each light guide is parallel but opposite in direction.

    Abstract: This invention pertains generally to the field of chemical synthesis and purification, and more specifically to methods of synthesizing and purifying certain 3,7 diamino-phenothiazin-5-ium compounds (referred to herein as “diaminophenothiazinium compounds”) including Methylthioninium Chloride (MTC) (also known as Methylene Blue). In one embodiment, the method comprises the steps of, in order: nitrosylation (NOS); nitrosyl reduction (NR); thiosulfonic acid formation (TSAF); oxidative coupling (OC); Cr(VI) reduction (CR); isolation and purification of zwitterionic intermediate (IAPOZI); ring closure (RC); chloride salt formation (CSF); one of: sulphide treatment (ST); dimethyldithiocarbamate treatment (DT); carbonate treatment (CT); ethylenediaminetetraacetic acid treatment (EDTAT); organic extraction (OE); and recrystallisation (RX). The present invention also pertains to the resulting (high purity) compounds, compositions comprising them (e.g.

  • Patent number: 7335652
    Abstract: Disclosed are methods for determining the stage of neurofibrillary degeneration associated with a tauopathy in a subject believed to suffer from the disease, by (i) introducing into the subject a ligand capable of labeling aggregated paired helical filament (PHF) tau protein, (ii) determining the presence and/or amount of ligand bound to extracellular aggregated PHF tau in the medial temporal lobe of the brain of the subject, (iii) correlating the result of the determination made in (ii) with the extent of neurofibrillary degeneration in the subject. The methods can be used for pre-mortem diagnosis and staging of tauopathies such as Alzheimer's Disease. Preferred ligands include sulphonated-benzothiazole-like compounds and diaminophenothiazines.

  • Publication number: 20080025949
    Abstract: This invention is in the field of chemical restructuring of pharmaceutical agents known to cause tissue toxicity as a side effect, by producing their orotate derivatives. More particularly, it concerns orotate derivatives of the anthracyclines, doxorubicin and daunorubicin, that are found to reduce levels of the pharmaceutical agent in noncancerous tissues. There orotate derivatives are equally efficacious in inhibiting the SCCAKI-1 kidney tumor in animals and the reduction in the heart tissue of doxorubicin compared with doxorubicin HCl suggests a reduction in toxicity induced by free radical generation by the anthrracyclines.
