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.

Quinolone resistance gene qnrB is upregulated by ciprofloxacin in a RecA/LexA-dependent manner, so that quinolone resistance development is an integral part of their mode of action in qnrB harboring. A quinolone antibiotic is a member of a large group of broad-spectrum bacteriocidals that share a bicyclic core structure related to the substance 4-quinolone. They are used in human and veterinary medicine to treat bacterial infections, as well as in animal husbandry. Our study of a number of halogenated alkyl and alkoxy 41H-quinolones highlights the potential for development of "endochin-like quinolones" ELQ, bearing an extended trifluoroalkyl moiety at the 3-position, that exhibit selective antiplasmodial effects in the low nanomolar range and inhibitory activity against chloroquine and atovaquone-resistant parasites. 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.

It was later followed by nalidixic acid, cinoxacin, rosoxacin, pipemidic acid, piromidic acid, and oxolinic acid. Quinolones that are in clinical development showing good activity against Gram-negative. Resistance to quinolone. Quinolone - an overview ScienceDirect Topics. Antimalarial quinolones Synthesis, potency, and.. Quinolones - SlideShare. Chloroquine is a 9-aminoquinoline known since 1934. Apart from its well-known antimalarial effects, the drug has interesting biochemical properties that might be applied against some viral infections. Chloroquine exerts direct antiviral effects, inhibiting pH-dependent steps of the replication of several viruses including members of the flaviviruses, retroviruses, and coronaviruses. Its best. Quinolone resistance associated with efflux pumps include modification of the major facilitator superfamily MFS of Gram-positive bacteria or the resistance–nodulation–division RND family, multiple antibiotic and toxin extrusion MATE, and ATP-binding cassette ABC of Gram-negative bacteria. 142 Mutations of efflux systems can alter their specificity for quinolones or cause upregulation. Chloroquine resistance is widespread in P. falciparum and is reported in P. vivax. Before using Chloroquine for prophylaxis, it should be ascertained whether Chloroquine is appropriate for use in the region to be visited by the traveler. Information regarding the geographic areas where resistance to Chloroquine occurs, is available at the.
