Efficacy of mefloquine and its enantiomers in a murine model of Mycobacterium avium infection.

The treatment of Mycobacterium avium infections is still long, complex, and often poorly tolerated, besides emergence of resistances. New active molecules that are more effective and better tolerated are deeply needed. Mefloquine and its enantiomers ((+) Erythro-mefloquine ((+)-EMQ) and (-)-Erythro-mefloquine ((-)-EMQ)) have shown efficacy in both in vitro and in vivo, in a mouse model of M.

Nocardia neocaledoniensis as Rare Cause of Spondylodiscitis.

Nocardia neocaledoniensis is a rare species of Nocardia bacteria, identified in 2004 in hypermagnesian ultramafic soil of New Caledonia. Culture of this opportunistic pathogen from spinal biopsy samples confirmed N. neocaledoniensis spondylodiscitis in an immunocompromised man.

Synergistic Activity of Clofazimine and Clarithromycin in an Aerosol Mouse Model of Infection.

Infections with nontuberculous mycobacteria (NTM) have a poor prognosis in patients with underlying respiratory diseases. Clofazimine (CFZ) showed both experimental and clinical promising results against clinically relevant NTM. However, there are no data on CFZ in combination with the current recommended treatment; therefore, we aimed to study its activity in an aerosol mouse model of In an aerosol infection BALB/c mouse model using strain Chester, we treated 58 mice with four combinations of rifampin (RIF) at 10 mg/kg, CFZ at 25 mg/kg, and clarithromycin (CLR) and ethambutol (EMB) at 100 mg/kg.

Synthesis and Study of New Quinolineaminoethanols as Anti-Bacterial Drugs.

The lack of antibiotics with a novel mode of action associated with the spread of drug resistant bacteria make the fight against infectious diseases particularly challenging. A quinoline core is found in several anti-infectious drugs, such as mefloquine and bedaquiline. Two main objectives were set in this work.
