Molecular Doorstop Can Be A Solution For Innovative Drugs To Cure Tuberculosis

Possessed to almost 1/4th of the population in the world, Tuberculosis kills almost 2 Million individuals each year. It is not only lethal but very old. Symptoms of this disease have been discovered in mummies found in Egypt. In spite of its age, the pathogen that is accountable for the illness, Mycobacterium tuberculosis, carries on to learn new methods. It has a specific ability for developing resistance to antibiotics, leaving thousands of millions of individuals with few options for treatment.

Now, study performed by Rockefeller researchers provides hope for a potent and new weapon in opposition to TB. This research was carried out below the leadership of Seth Darst and Elizabeth Campbell. Their research, which is published in eLife, aims on an antibiotic that slaughters mycobacterium tuberculosis in the lab, but is not appropriate for medical use. By clarifying how the drug works, their study may permit others to develop fresh antibiotics that can in fact be employed to cure patients suffering from TB and may even operate on other diseases.

Campbell clarifies that fidaxomicin, the antibiotic in limelight, is unusually skillful at slaughtering mycobacterium tuberculosis developed in the laboratory. To be helpful in the real world in opposition to TB, an antibiotic should be engrossed by the gut and ultimately reach the lungs when consumed. This is something that fidaxomicin is not able to perform.

Fidaxomicin aims on an enzyme dubbed as RNAP (RNA polymerase), which makes RNA from DNA, a procedure essential for life. The enzyme owns a clamp, or hinged pincer, that closes down to protect DNA for conversion.

Researchers assumed that the drug operates by somehow meddling with this clamp. But they did not know exactly how the molecule does its job. This is the knowledge that can be important for making more helpful variants of fidaxomicin.
