Biological Activity

Description	Closantel is a gram positive antibacterial activity inhibitor, inhibiting the KinA/Spo0F system with IC50 of 3.8 μM.

In vitro
In vitro	Closantel inhibits drug resistant S. aureus and E. faecium with MICs of 1 μg/mL and 1 μg/mL. Closantel inhibits MRSA and E.faecalis with MICs of 2 μg/mL and 1 μg/mL. ^[1] Closantel completely blocks the infection of host cells with E. chaffeensis or A. phagocytophilum, treatment of infected cells 1 day post infection with closantel clears infection in dose-dependent manner. Closantel inhibits the autokinase activities of the three E. chaffeensis sensor kinases from E. chaffeensis. ^[2] Closantel (50 μg/mL) causes an initial burst of contractions of much greater amplitude and frequency than normal in tissue vessel, the stimulation of amplitude and frequency lasted for nearly 15 min and is accompanied by a rise in muscle tone, which reaches a maximum at 16 min, at a level greater than 1.5 times the maximal normal amplitude. ^[3]

In Vivo
In vivo	Closantel (10 mg/kg) results in gross surface damage from 24 hours onwards in rats administrated with 25 metacercarial cysts of F. hepatica, in the form of erosion of the anterior and posterior extremities of the fluke and large-scale sloughing of the tegument on both dorsal and ventral surfaces. ^[3] Closantel (7.5 mg/kg) combined with broad-spectrum anthelmintic is very effective against H. contortus but ineffective against Trichostrongylus spp in lambs. ^[4] Closantel significantly reduces isotope levels in closantel-resistant adult Haemonchus contortus infected sheep. ^[5]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
