Anti Estrogen Steroids Raw Steroid Powder Trilostane CAS 13647-35-3 For Breast Cancer
Abstracto
Trilostane is an inhibitor of isoforms 3β-HSD and 3β-HSD2 of the enzyme 3β-hydroxysteroid dehydrogenase, which plays a role in adrenal steroid biosynthesis. Investigators believe that Arg195 in 3β-HSD versus Pro195 in 3β-HSD2 attributes to the competitive inhibition of 3β-HSD, but not 3β-HSD2 by Trilostane. Research shows that trilostane is effective in suppressing the intracellular production oin LNCaP-FGC prostate cancer cells and inhibiting cortisol biosynthesis in the human adrenal gland. This product serves as a useful tool in steroid biosynthesis research.

Usos
Trilostane can suppress cortical hormone synthesis process of 3 beta dehydrogenase, make cortisol, aldosterone synthesis reduce, clinical used in the treatment of Cushing syndrome(cortisol increase disease) and primary aldosteronism,the effect is not good than testosterone metyrapone. This product has significantly reduced blood testosterone level role, may relevant to its inhibit synthetic.
Aplicaciones
trilostano,The anti estrogen steroids drug Trilostane was previously available in the United Kingdom for use in humans under the brand name Modrenal for the treatment of Cushing’s disease and for breast cancer. It was approved in the United States in 2008 for the treatment of Cushing’s disease (hyperadrenocorticism) in dogs under the brand name Vetoryl. It was available by prescription in the UK under the Vetoryl brand name for some time before it was approved in the US. The drug is also used to treat the skin disorder Alopecia X in dogs. It is also the first drug approved to treat both pituitary- and adrenal-dependent Cushing’s in dogs. This prescription drug works by stopping the production of cortisol in the adrenal glands.
trilostano,The anti estrogen steroids drug Vetoryl is used to treat Cushing’s syndrome (also known as Cushings disease or hyperadrenocorticism). This is a hormone problem associated with abnormally high levels of cortisone in the blood stream of affected dogs. The main symptoms caused are excessive thirst and hunger. It also affects the dog’s appearance and reduces its quality of life. Dogs may show hair loss, weight gain, lethargy, loss of bladder control and a bloated stomach.
trilostano,Cushing’s disease is a condition that will be present in the dog’s system for the rest of its life and will need to be treated continually. Vetoryl tackles this problem in the pituitary and adrenal glands. Cortisol levels are reduced which leads to a reduction in symptoms and Vetoryl can make a difference in just three months.
trilostano,The capsules are available in four strengths depending on the size of the dog and should only be prescribed by a vet. There are a number of contra-indications which should be taken into consideration prior to treatment. Dogs that are pregnant or who have problems with the liver or kidneys should not take this medication.
