Exploring novel amides as efflux pump inhibitors for overcoming antibiotic resistance in multidrug-resistant Pseudomonas aeruginosa

Iranian Journal of Microbiology
Background and Objectives: Pseudomonas aeruginosa (P. aeruginosa), a multidrug-resistant bacterium, represents a considerable risk in healthcare environments owing to its capacity to induce various infections. The resistance of P.

Discovery and Optimization of AMT‐676, a CDH17‐Targeting ADC for the Treatment of Advanced Gastrointestinal Cancers

Advanced Science, EarlyView.
AMT‐676 is a novel antibody‐drug conjugate targeting CDH17, an adhesion molecule uniquely exposed on gastrointestinal tumor surfaces. Engineered with an optimized exatecan payload, it demonstrates profound tumor regression and a robust bystander effect across diverse preclinical models.

Characterisation of the vibrio cholerae antibiotic resistance var operon [PDF]

, 2007
The discovery and use of antibiotics in the chemotherapy of bacterial infections has revolutionised medicine as it is today. Unfortunately, the progressive use of antibiotics has promoted the evolution of bacterial defences against these mediators and ...

The MoSR‐MoDde1 Regulatory Axis: A Novel Determinant of DMI Sensitivity and a Target for Sustainable Rice Blast Control

Advanced Science, EarlyView.
The transcription factor MoSR governs DMI fungicide sensitivity in Magnaporthe oryzae through dual regulation of ergosterol biosynthesis and the detoxification enzyme MoDde1. Targeting MoDde1 via a small‐molecule inhibitor or host‐induced gene silencing enhances DMI efficacy against rice blast, offering a sustainable disease management strategy ...

A novel inhibitor of multidrug efflux pumps in Staphylococcus aureus [PDF]

Journal of Antimicrobial Chemotherapy, 2002
GG918, a synthetic inhibitor of P-glycoprotein-mediated mammalian tumour multidrug resistance, was found to be equipotent to reserpine in enhancing the in vitro activity of norfloxacin and ciprofloxacin against strains of Staphylococcus aureus expressing distinct efflux-related multidrug resistance pumps. Four- to eight-fold reductions in MICs of these

Biophysical and biochemical characterisation of the SMR proteins Hsmr and EmrE [PDF]

, 2011
The increasing resistance of almost all pathogenic bacteria to antibiotics (multidrug resistance) causes a severe threat to public health. The mechanisms underlying multidrug resistance include the induced over expression of multidrug transporters which ...

Structural and functional aspects of the multidrug efflux pump AcrB [PDF]

bchm, 2009
Abstract The tripartite efflux system AcrA/AcrB/TolC is the main pump in Escherichia coli for the efflux of multiple antibiotics, dyes, bile salts and detergents. The inner membrane component AcrB is central to substrate recognition and energy transduction and acts as a proton/drug antiporter.

Emergence of a Potent Multidrug Efflux Pump Variant That Enhances Campylobacter Resistance to Multiple Antibiotics

mBio, 2016
Bacterial antibiotic efflux pumps are key players in antibiotic resistance. Although their role in conferring multidrug resistance is well documented, the emergence of “super” efflux pump variants that enhance bacterial resistance to multiple drugs has ...

Fungicide-driven evolution and molecular basis of multidrug resistance in field populations of the grey mould fungus Botrytis cinerea [PDF]

, 2009
The grey mould fungus Botrytis cinerea causes losses of commercially important fruits, vegetables and ornamentals worldwide. Fungicide treatments are effective for disease control, but bear the risk of resistance development.
