General description

Clofazimine is a riminophenazine, which is used as an antileprosy drug. It is used to treat multidrug-resistant tuberculosis. Clofazimine prevents neutrophil motility and lymphocyte transformation. It has anti-inflammatory effect, which is used to treat discoid lupus erythematosus. Clofazimine has immunosuppressive property.

Application

Clofazimine has been used:
  • for antimicrobial preparation
  • to study its accumulation on macrophages to form crystal-like drug inclusions (CLDIs)
  • to model drug-induced hepatic granulomatous inflammation
  • to study the in vivo cargo storage capacity of macrophages

During Mycobacterium tuberculosis infection, a population of bacteria likely becomes refractory to antibiotic killing in the absence of genotypic resistance, making treatment challenging. We describe an in vitro model capable of yielding a phenotypically antibiotic-tolerant subpopulation of cells, often called
