In vitro

Amitraz was not cytotoxic to human luteinized granulosa cells at concentrations of 1, 10 or 50 µg/ml for exposures of 2-72 h While the highest concentration of amitraz tested, 100 µg/ml, caused significant cell death after exposures of 24, 48 and 72 h. Amitraz decreased the amount of progesterone produced by each cell after a 4 h exposure; the reduction in progesterone concentration was not caused by decreased cell viability[1].

In vivo Amitraz is an α2-adrenergic receptor (α2-AR) agonist that adversely affects the mammalian reproductive system by binding to presynaptic α2-AR in the hypothalamus, thus inhibiting noradrenalin release and decreasing GnRH secretion. When 30 mg/kg of amitraz was administered to rats, the ovulatory LH surge was prevented. Amitraz inhibited insulin but stimulated glucagon secretion in a perfused rat pancreas model. Amitraz also decreased intestinal motility, and inhibited prostaglandin synthesis by bovine seminal vesicle microsomes. Amitraz can be absorbed through the skin and can exert systemic effects via the vascular system in humans[1]. Low doses of AMZ (l-25 mg/kg) decreased motor activity and altered the rates and patterns of responding under schedule-controlled conditions. Intermediate doses (50-100 mg/kg) affect visual-evoked potentials and lower body weight and temperature. In addition, 100 mg/kg produces slight MAO inhibition and characteristic signs of intoxication (e.g., weight loss and hyperreactivity). High doses (>lOO mg/kg) produce more pronounced MAO inhibition, extreme weight loss and hyperreactivity, aggression, and lethality[2].

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.
