    Chloroquine ferroquine and ruthenoquine structure

    Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence and spread of resistance. It is recommended to check if chloroquine is still effective in the region prior to using it.

    Chloroquine has a high affinity for tissues of the parasite and is concentrated in its cytoplasm. As a weak base, it increases the pH of the intracellular lysosome and endosome. A more acidic medium in these organelles is needed for the parasite to affect mammalian cells. As a result, chloroquine inhibits growth and development of parasites. In addition, ferroquine retains all the features that have been identified as necessary in the structure of chloroquine see Figure 4. The similarity of behaviour of the ruthenoquine and ferroquine molecules opens an interesting avenue of research. Ruthenium is known to be a good contrasting agent in electron microscopy. It is reasonable, in the absence of data to the contrary, to postulate that the mechanism of action of ruthenoquine and ferroquine is similar. A ferrocene–quinoline conjugate named ferroquine FQ or SSR97193 is active against both chloroquine-susceptible and chloroquine-resistant Plasmodium falciparum and P. vivax strains and/or isolates. FQ was shown to be efficient for the treatment of uncomplicated malaria in humans phase IIb of clinical trials.

    The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations. In areas where resistance is present, other antimalarials, such as mefloquine or atovaquone, may be used instead.

  5. This gene is imprinted, with preferential expression from the maternal allele. Mutations in this gene have been found in Wilms' tumor and lung cancer. This protein may act as a transporter of organic cations, and have a role in the transport of chloroquine and quinidine-related compounds in kidney.

    Inhibition of hemozoin biocrystallization is considered the main mechanism of action of 4-aminoquinoline antimalarials including chloroquine CQ but cannot fully explain the activity of ferroquine FQ which has been related to redox properties and intramolecular hydrogen bonding. Analogues of FQ, methylferroquine Me-FQ, ruthenoquine RQ, and methylruthenoquine Me-RQ, were prepared. Synthetic derivatives of quinine were the 8-aminoquinoline primaquine and the 4-aminoquinoline chloroquine CQ. When resistance to CQ emerged in the late 1950 s, the strategy was to modify the chemical structure of the existing compounds. The synthesis of CQ-like drugs led to the discovery of amodiaquine AQ. Ferroquine FQ, or SSR97193, is a novel antimalarial drug currently in phase I clinical trials. FQ is a unique organometallic compound designed to overcome the chloroquine CQ resistance problem. FQ revealed to be equally active on CQ-sensitive and CQ-resistant Plasmodium falciparum laboratory strains and field isolates.

    Dermatomyositis Medication Disease-Modifying Antirheumatic. Sep 26, 2018 Prednisone is first-line therapy for dermatomyositis. It may decrease inflammation by reversing increased capillary permeability and suppressing polymorphonuclear PMN leukocyte activity. It may be beneficial to use intravenous IV pulses; this may be associated with a lower frequency of calcinosis.
