The transcriptome of Mycobacterium tuberculosis in a lipid-rich dormancy model through RNAseq analysis [PDF]
, 2017 Tuberculosis (TB) is currently the number one killer among infectious diseases worldwide. Lipids are abundant molecules during the infectious cycle of Mycobacterium tuberculosis (Mtb) and studies better mimicking its actual metabolic state during ...

Synthesis of Berberine—Efflux Pump Inhibitor Hybrid Antibacterials [PDF]
Synthetic Communications, 2010 This paper reports the compact synthesis of two isomeric dual-action hybrid antimicrobials where the 13-position of the antibacterial berberine has been linked via 3'- and 4'-methylene bridges to INF55 (5-nitro-2-phenylindole), an inhibitor of the bacterial NorA multidrug-resistance pump.

RND-type Drug Efflux Pumps from Gram-negative bacteria: Molecular Mechanism and Inhibition
Frontiers in Microbiology, 2015 Drug efflux protein complexes confer multidrug resistance on bacteria by transporting a wide spectrum of structurally diverse antibiotics. Moreover, organisms can only acquire resistance in the presence of an active efflux pump.

Antisense PNA accumulates in Escherichia coli and mediates a long post-antibiotic effect [PDF]
, 2007 Antisense agents that target growth-essential genes display surprisingly potent bactericidal properties. In particular, peptide nucleic acid (PNA) and phosphorodiamidate morpholino oligomers linked to cationic carrier peptides are effective in time kill ...

Not only P-glycoprotein: amplification of the ABCB1-containing chromosome region 7q21 confers multidrug resistance upon cancer cells by coordinated overexpression of an assortment of resistance-related proteins [PDF]
, 2017 The development of drug resistance continues to be a dominant hindrance toward curative cancer treatment. Overexpression of a wide-spectrum of ATP-dependent efflux pumps, and in particular of ABCB1 (P-glycoprotein or MDR1) is a well-known resistance ...

Cellular catabolism of the iron-regulatory peptide hormone hepcidin. [PDF]
, 2013 Hepcidin, a 25-amino acid peptide hormone, is the principal regulator of plasma iron concentrations. Hepcidin binding to its receptor, the iron exporter ferroportin, induces ferroportin internalization and degradation, thus blocking iron efflux from ...

Efflux pump inhibitors: targeting mycobacterial efflux systems to enhance TB therapy [PDF]
Journal of Antimicrobial Chemotherapy, 2015 The emergence of drug resistance continues to plague TB control, with a global increase in the prevalence of MDR-TB. This acts as a gateway to XDR-TB and thus emphasizes the urgency for drug development and optimal treatment options. Bedaquiline is the first new anti-TB drug approved by the FDA in 40 years and has been shown to be an effective ...
