Clioquinol
Clioquinol (iodochlorhydroxyquin) is an antifungal drug and antiprotozoal drug. It is neurotoxic in large doses. It is a member of a family of drugs called hydroxyquinolines which inhibit certain enzymes related to DNA replication. The drugs have been found to have activity against both viral and protozoal infections. Antiprotozoal use A 1964 report described the use of clioquinol in both the treatment and prevention of shigella infection and ''Entamoeba histolytica'' infection in institutionalized individuals at Sonoma State Hospital in California. The report indicates 4000 individuals were treated over a 4-year period with few side effects. Several recently reported journal articles describing its use as an antiprotozoal include: * A 2005 reference to its use in treating a Dutch family for ''Entamoeba histolytica'' infection. * A 2004 reference to its use in the Netherlands in the treatment of ''Dientamoeba fragilis'' infection. * A 1979 reference to the use in Zaire in ...

PBT2
PBT2 is a safe-for-human-use Zinc ionophore and an experimental drug candidate. It is a second-generation 8-hydroxyquinoline analog intended to be a successor to clioquinol and a potential treatment of Alzheimer's disease and Huntington's disease. Clinical trials PBT2 was the subject of three phase II clinical trials for Alzheimer's disease ('EURO'), 'IMAGINE' & 'IMAGINE EXTENSION') and one for Huntington's disease ('REACH2HD') trial. The cognition efficacy results for Alzheimer's disease were mixed. The EURO trial showed some improvements in cognitive functions, in particular executive function domains, while the IMAGINE study did not."Prana Biotech Plunges 76%; Drug Fails in Alzheimer Study""PBT2 Takes a Dive in Phase 2 Alzheimer's Trial" Although there is no evidence that PBT2 is of any benefit in Alzheimer's dementia,''"There is no evidence that MPACs (PBT1 or PBT2) are of benefit in Alzheimer's dementia"'' the number of subjects treated with PBT2 for AD in Phase II placeb ...

Subacute Myelo-optic Neuropathy
Subacute myelo-optic neuropathy (SMON) is an iatrogenic disease of the nervous system leading to a disabling paralysis, blindness and even death. Its defining manifestation was as an epidemic in Japan during the 1960s: the Japanese government estimated 11,000 were affected; however, the College of Medicine at the University of Tokyo put the number at 30,000, citing a lack of preservation of medical records for longer than five years and a lack of cooperation from doctors as the reasons for the discrepancy. On August 3, 1978, the Tokyo District Court ruled that the cause of SMON is Clioquinol. Its manufacturer, Ciba-Geigy, has publicly stated that "Medical products manufactured and sold by us have been responsible for the occurrence of MONin Japan, we extend our apologies." SMON was first observed and diagnosed in Sweden 1966, by the pediatrician and neurologist Olle Hansson.Hansson, Olle: Inside Ciba-Geigy, 1989 Clioquinol was marketed as a prophylaxis to tourist diarrhoea.

Antifungal Drug
An antifungal medication, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis (thrush), serious systemic infections such as cryptococcal meningitis, and others. Such drugs are usually yes obtained by a doctor's prescription, but a few are available over the counter (OTC). Types of antifungal There are two types of antifungals: local and systemic. Local antifungals are usually administered topically or vaginally, depending on the condition being treated. Systemic antifungals are administered orally or intravenously. Of the clinically employed azole antifungals, only a handful are used systemically. These include ketoconazole, itraconazole, fluconazole, fosfluconazole, voriconazole, posaconazole, and isavuconazole. Examples of non-azole systemic antifungals include griseofulvin and terbinafine.

Parkinson's Disease
Parkinson's disease (PD), or simply Parkinson's, is a long-term degenerative disorder of the central nervous system that mainly affects the motor system. The symptoms usually emerge slowly, and as the disease worsens, non-motor symptoms become more common. The most obvious early symptoms are tremor, rigidity, slowness of movement, and difficulty with walking. Cognitive and behavioral problems may also occur with depression, anxiety, and apathy occurring in many people with PD. Parkinson's disease dementia becomes common in the advanced stages of the disease. Those with Parkinson's can also have problems with their sleep and sensory systems. The motor symptoms of the disease result from the death of cells in the substantia nigra, a region of the midbrain, leading to a dopamine deficit. The cause of this cell death is poorly understood, but involves the build-up of misfolded proteins into Lewy bodies in the neurons. Collectively, the main motor symptoms are also known as ...

Antiprotozoal Agents
Antiprotozoal agents ( ATC code: ATC P01) is a class of pharmaceuticals used in treatment of protozoan infection. A paraphyletic group, protozoans have little in common with each other. For example, ''Entamoeba histolytica'', a unikont eukaryotic organism, is more closely related to ''Homo sapiens'' (humans), which also belongs to the unikont phylogenetic group, than it is to ''Naegleria fowleri'', a "protozoan" bikont. As a result, agents effective against one pathogen may not be effective against another. Antiprotozoal agents can be grouped by mechanism or by organism. Recent papers have also proposed the use of viruses to treat infections caused by protozoa. Medical uses Antiprotozoals are used to treat protozoal infections, which include amebiasis, giardiasis, cryptosporidiosis, microsporidiosis, malaria, babesiosis, trypanosomiasis, Chagas disease, leishmaniasis, and toxoplasmosis. Currently, many of the treatments for these infections are limited by their toxicity. Outdat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ionophore
In chemistry, an ionophore () is a chemical species that reversibly binds ions. Many ionophores are lipid-soluble entities that transport ions across the cell membrane. Ionophores catalyze ion transport across hydrophobic membranes, such as liquid polymeric membranes (carrier-based ion selective electrodes) or lipid bilayers found in the living cells or synthetic vesicles (liposomes). Structurally, an ionophore contains a hydrophilic center and a hydrophobic portion that interacts with the membrane. Some ionophores are synthesized by microorganisms to import ions into their cells. Synthetic ion carriers have also been prepared. Ionophores selective for cations and anions have found many applications in analysis. These compounds have also shown to have various biological effects and a synergistic effect when combined with the ion they bind. Classification Biological activities of metal ion-binding compounds can be changed in response to the increment of the metal concentrati ...

Clk-1
Mitochondrial 5-demethoxyubiquinone hydroxylase (DMQ hydroxylase), also known as ''coenzyme Q7, hydroxylase'', is an enzyme that in humans is encoded by the ''COQ7'' gene. The ''clk-1'' (''clock-1'') gene encodes this protein that is necessary for ubiquinone biosynthesis in the worm '' Caenorhabditis elegans'' and other eukaryotes. The mouse version of the gene is called ''mclk-1'' and the human, fruit fly and yeast homolog ''COQ7'' (coenzyme Q biosynthesis protein 7). CLK-1 is not to be confused with the unrelated human protein CLK1 which plays a role in RNA splicing. Structure The protein has two repeats of approximately 90 amino acids, that contain two conserved motifs predicted to be important for coordination of iron. The structure and function of the gene are highly conserved among different species. The ''C. elegans'' protein contains 187 amino acid residues (20 kilodaltons), the human homolog 217 amino acid residues (24 kilodaltons, gene consisting of six exons ...
