Clofazimine exerts a slow bactericidal effect on Mycobacterium leprae (Hansen's bacillus). Clofazimine inhibits mycobacterial growth and binds preferentially to mycobacterial DNA. Clofazimine also exerts anti-inflammatory properties in treating erythema nodosum leprosum reactions. However, its precise mechanisms of action are unknown

Mechanism Clofazimine works by binding to the guanine bases of bacterial DNA, thereby blocking the template function of the DNA and inhibiting bacterial proliferation. [11] [12] It also increases activity of bacterial phospholipase A2, leading to release and accumulation of lysophospholipids, [11] [12] which are toxic and inhibit bacterial proliferation Morrison, N. E. (1979). Mechanism of action of clofazimine. International Journal of Leprosy, 47 (2 Sup.), VII 227. Mechanism of action of clofazimine. / Morrison, N. E.

Morrison, NE 1979, ' Mechanism of action of clofazimine ', International Journal of Leprosy, vol Clofazimine (CFZ) is one such drug that has recently attracted interest against DR-TB. CFZ is a hydrophobic riminophenazine that was initially synthesized as an anti-TB antibiotic. Although the mechanisms of action of CFZ are not yet entirely understood, it has been suggested that outer membrane is its primary action site, and the respiratory chain and ion transporters are the putative targets

Clofazimine C27H22Cl2N4 - PubChe

Putative membrane-directed mechanisms of the antimicrobial activity of clofazimine include the respiratory chain and ion transporters. Intracellular redox cycling, involving oxidation of reduced clofazimine, leads to the generation of antimicrobial ROS, superoxide and H 2 O 2 The Irish group that discovered clofazimine suggested that the antimycobacterial activity of this agent was attributable to two unusual properties, these being its high lipophilicity, enabling efficient transmembrane penetration, together with a redox potential of −0.18 V at pH 7, 25 favouring intracellular redox cycling. 43 Intracellular oxidation of reduced clofazimine was proposed to result in the generation of antimicrobial reactive oxygen species (ROS). 25 However, convincing evidence. In the case of bedaquiline, the primary target is the key respiratory chain enzyme F 1 /F 0-ATPase, whereas clofazimine is less selective, apparently inhibiting several targets, which may underpin the extremely low level of resistance to this agent. This review is focused on similarities and differences between clofazimine and bedaquiline, specifically in respect of molecular mechanisms of antimycobacterial action, targeting of quiescent and metabolically active organisms, therapeutic. Clofazimine [3-(p-chloroanilino)-10-(p-chlorophenyl)-2,10-dihydro-2-(isopropylimino) phenazine] (Figure 1A) is a lipophilic riminophenazine compound that possesses antimycobacterial activities , ; however, the mechanism has not been fully elucidated. Clofazimine is highly lipophilic and appears to bind strongly to mycobacterial DNA . The binding of the drug to DNA appears to occur principally at base sequences containing guanine, which may explain clofazimine's preference for the G+C-rich. Clofazimine possesses both antimicrobial and anti-inflammatory properties [ 21 ]. It is active against both slowly growing and rapidly growing mycobacteria and most Gram-positive bacteria in vitro [ 21, 24 ]

Clofazimine: A review of its medical uses and mechanisms

Key results: Clofazimine blocked Kv 1.3 channels by involving two discrete mechanisms, both of which contribute to effective suppression of channels: (i) a use-dependent open-channel block during long depolarizations, resulting in accelerated K(+) current inactivation and (ii) a block of closed deactivated channels after channels were opened by brief depolarizations. Both modes of block were use-dependent and state-dependent in that they clearly required prior channel opening The advantage with clofazimine is the anti-inflammatory action and its resultant efficacy in type II reactions. The possible mechanism of action being stimulation of prostaglandin E2 synthesis and inhibition of neutrophil motility together with selective suppression of Th 1 subtype of T-helper cells which may also add to its role in type II.

Pharmacokinetics: Absorption: Rapidly and almost completely absorbed from the gastrointestinal tract. Bioavailability: >86%. Time to peak plasma concentration: Within 2-8 hours of drug action. Administration by other routes may result in less availability due to incom-plete absorption. When this occurs, less of the drug is delivered by the bloodstream to the site of action.

Rifampicin, also known as rifampin, is an antibiotic used to treat several types of bacterial infections, including tuberculosis (TB), Mycobacterium avium complex, leprosy, and Legionnaires' disease. It is almost always used together with other antibiotics with two notable exceptions: when given as a preferred treatment that is strongly recommended for latent TB infection; and when used as.

An antimicrobial is a substance that kills or inhibits the growth of microorganisms such as bacteria, fungi, or protozoans. Antimicrobial drugs either kill microbes (microbiocidal) or prevent the growth of microbes (microbiostatic). Disinfectants are antimicrobial substances used on non-living objects or outside the body Lidocaine, also known as lignocaine and sold under the brand name Xylocaine among others, is a local anesthetic of the amino amide type.
