The spread of AMR bacteria could dramatically set back modern medicine to the dark age of the pre-antibiotic era; achievements in modern medicine, such as the increased safety of childbirth, caesarean sections, treatment of preterm babies, major or even minor surgery, treatment of pneumonia, organ transplantation and cancer chemotherapy, which we today take for granted, would not be possible without access to effective treatment for bacterial infections.<\/p>\n<p>In addition to increased resistance to existing agents, there is a lack of new antibiotics in development, according to a study by the European Medicines Agency. Within just a few years, we might be faced with dire setbacks, medically, socially, and economically, unless real global coordinated actions are immediately taken. The projection of 10 million deaths a year by 2050 is greater than the current annual death toll from cancer.<\/p>\n<p>\u201cDuring the course of infection, bacteria need to multiply inside the body, and they require active DNA synthesis to multiply,\u201d says Eduard Torrents, who heads the Bacterial Infections: Antimicrobial Therapies group at IBEC. \u201cBy targeting the key enzyme that allows this to happen, we can inhibit the growth of various types of undesirable and disease-causing bacteria.\u201d<\/p>\n<p><img decoding=\"async\" class=\"alignright wp-image-15587 size-medium lazyload\" data-src=\"https:\/\/ibecbarcelona.eu\/wp-content\/uploads\/2015\/03\/eduarddr-300x192.jpg\" alt=\"eduarddr\" width=\"300\" height=\"192\" data-srcset=\"https:\/\/ibecbarcelona.eu\/wp-content\/uploads\/2015\/03\/eduarddr-300x192.jpg 300w, https:\/\/ibecbarcelona.eu\/wp-content\/uploads\/2015\/03\/eduarddr-203x130.jpg 203w, https:\/\/ibecbarcelona.eu\/wp-content\/uploads\/2015\/03\/eduarddr-150x96.jpg 150w, https:\/\/ibecbarcelona.eu\/wp-content\/uploads\/2015\/03\/eduarddr.jpg 500w\" data-sizes=\"(max-width: 300px) 100vw, 300px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 300px; --smush-placeholder-aspect-ratio: 300\/192;\" \/>The molecule, known as M-HA, works as a \u2018radical scavenger\u2019 compound to inhibit ribonucleotide reductase, an essential enzyme in DNA replication and repair. It also demonstrates low toxicity in eukaryotic cells, which heralds a great improvement on existing RNR-inhibiting drugs, which are mostly used against cancer or viruses and are too toxic to be used as antibacterials.<\/p>\n<p>\u201cIt\u2019s crucial that we find new antibacterials that function in a new way, like this one, in order to replace the existing antibiotics that are being rendered useless by bacterical resistance,\u201d says Eduard. \u201cThese new drug candidates should also work in a way which will not allow such a level of resistance to build up all over again.\u201d<\/p>\n<p>The researchers tested M-HA and revealed its capacity to inhibit the growth of undesirables such as <em>Pseudomonas<\/em> and <em>Mycobacterium<\/em> bacterial pathogens, including <em>Staphylococcus aureus, S.sanguinis and S.mutans, Mycobacterium, P. aeruginosa<\/em> and <em>B. cenocepacia.<\/em><\/p>\n<p>\u201cDuring 2014, the WHO, Prime Minister David Cameron, President Obama and the World Economic Forum made AMR the focus of highly visible reports and actions, recognizing the global nature of the crisis and calling for local and international leadership and co-ordinated actions to tackle it,\u201d says Dr. Joan Gavald\u00e0 of VHIR\u2019s Infectious Diseases research group. \u201cIt\u2019s starting to be acknowledged that there\u2019s an crucial need for funding for research relevant to developing new antibiotics and alternatives for treating AMR, as well as increasing economic incentives for developing urgently needed antibiotics and to preserve antibiotic effectiveness. New antimicrobials with new mechanisms of action against gram-negative bacteria, like ours, are urgently needed in order to preserve medicine as we know it.\u201d<\/p>\n<p>&#8212;<\/p>\n<p><strong><em>Reference article:<\/em> <\/strong>Esther Juli\u00e1n, Aida Baelo, Joan Gavald\u00e0 &amp; Eduard Torrents (2015). <a href=\"http:\/\/journals.plos.org\/plosone\/article?id=10.1371\/journal.pone.0122049\">Methyl-hydroxylamine as an efficacious antibacterial agent that targets the ribonucleotide reductase enzyme.<\/a>\u00a0<em>PLoS ONE<\/em> 10(3): e0122049<\/p>\n<p>&#8212;<\/p>\n<p><strong>IBEC in the Media:<\/strong> There was coverage of this story in\u00a0<a href=\"https:\/\/ibecbarcelona.eu\/wp-content\/uploads\/2015\/04\/2015-03-23-GacetaMedica-ETorrents-Una-nueva-mole\u0301cula-reprime-la-replicacio\u0301n-del-ADN.pdf\">Gaceta M\u00e9dica<\/a> on 23 March and in\u00a0<a href=\"https:\/\/ibecbarcelona.eu\/wp-content\/uploads\/2015\/04\/2015-04-07-DiaridTerrassa-ETorrents-Estudiamos-las-infecciones-en-el-instestino-de-la-bacteria-EColi.pdf\">Diario de Terrassa<\/a> on 7 April.<\/p>\n","protected":false},"excerpt":{"rendered":"<h3><img decoding=\"async\" data-src=\"https:\/\/ibecbarcelona.eu\/wp-content\/uploads\/2015\/03\/torrents-feb-2015-image-sm.jpg\" alt=\"torrents feb 2015 image sm\" width=\"500\" height=\"242\" class=\"left size-full wp-image-15590 lazyload\" data-srcset=\"https:\/\/ibecbarcelona.eu\/wp-content\/uploads\/2015\/03\/torrents-feb-2015-image-sm.jpg 500w, https:\/\/ibecbarcelona.eu\/wp-content\/uploads\/2015\/03\/torrents-feb-2015-image-sm-300x145.jpg 300w, https:\/\/ibecbarcelona.eu\/wp-content\/uploads\/2015\/03\/torrents-feb-2015-image-sm-230x111.jpg 230w, https:\/\/ibecbarcelona.eu\/wp-content\/uploads\/2015\/03\/torrents-feb-2015-image-sm-150x73.jpg 150w\" data-sizes=\"(max-width: 500px) 100vw, 500px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 500px; --smush-placeholder-aspect-ratio: 500\/242;\" \/>The increasing prevalence of bacteria that are resistant to current antibiotics pose an escalating threat to human health.
