Resisting Bacterial Drug Resistance [PDF]
Chemistry & Biology, 2003 In this issue of Chemistry & Biology, Wright and colleagues report an elegant method for inhibiting enzymes critical for rendering bacteria drug resistant. By using cationic peptides as inhibitors, the authors have exploited two antibacterial mechanisms, making it doubly difficult for microbial retaliation.

HATs On for Drug Resistance [PDF]
Cell Host & Microbe, 2011 Mutations in the human cytomegalovirus UL27 gene confer resistance to an inhibitor of the viral protein kinase UL97. Reitsma and colleagues (2011) demonstrate that UL27 destabilizes the Tip60 histone acetyltransferase, setting forth intriguing new mechanisms for antiviral drug resistance and for viral regulation of the cell cycle.

Rv1453 is associated with clofazimine resistance in Mycobacterium tuberculosis
Microbiology Spectrum, 2023 Clofazimine (CFZ) has been repurposed for treating tuberculosis (TB), especially multidrug-resistant tuberculosis (MDR-TB). However, the mechanisms of resistance to clofazimine are poorly understood.

Drug resistant tuberculosis [PDF]
BMJ, 1995 EDITOR,—Concern is growing over the spread of drug resistant Mycobacterium tuberculosis. New evidence suggests that this spread may be increasing in certain sections of the British population. The recent advances in molecular techniques have equipped us with the means to make substantial inroads into the possible impact of drug resistant tuberculosis.1

Understanding the role of phenotypic switching in cancer drug resistance [PDF]
Journal of Theoretical Biology, 490 (2020), 110162, 2020 The emergence of acquired drug resistance in cancer represents a major barrier to treatment success. While research has traditionally focused on genetic sources of resistance, recent findings suggest that cancer cells can acquire transient resistant phenotypes via epigenetic modifications and other non-genetic mechanisms.

Mutational pathway determines whether drug gradients accelerate evolution of drug-resistant cells [PDF]
Phys. Rev. Lett. 109, 088101 (2012), 2012 Drug gradients are believed to play an important role in the evolution of bacteria resistant to antibiotics and tumors resistant to anti-cancer drugs. We use a statistical physics model to study the evolution of a population of malignant cells exposed to drug gradients, where drug resistance emerges via a mutational pathway involving multiple mutations.

Irreversible evolution, obstacles in fitness landscapes and persistent drug resistance [PDF]
arXiv, 2023 We use fitness graphs, or directed cube graphs, for analyzing evolutionary reversibility. The main application is antimicrobial drug resistance. Reversible drug resistance has been observed both clinically and experimentally. If drug resistance depends on a single point mutation, then a possible scenario is that the mutation reverts back to the wild ...

Sudapyridine (WX-081), a Novel Compound against Mycobacterium tuberculosis
Microbiology Spectrum, 2022 Bedaquiline (BDQ) was historically listed by the World Health Organization (WHO) in 2018 as the preferred option for rifampin-resistant tuberculosis (RR-TB) and multidrug-resistant tuberculosis (MDR-TB). However, when there is no other effective regimen,
