25122-46-7 Usage
Mechanism of Action
Clobetasol Propionate is the propionate salt form of clobetasol, a topical synthetic corticosteroid with anti-inflammatory, anti-pruritic, and vasoconstrictive properties. Clobetasol propionate exerts its effect by binding to cytoplasmic glucocorticoid receptors and subsequently activates glucocorticoid receptor mediated gene expression. This results in the synthesis of certain anti-inflammatory proteins, while inhibiting the synthesis of certain inflammatory mediators. Specifically, clobetasol propionate appears to induce phospholipase A2 inhibitory proteins, thereby controlling the release of the inflammatory precursor arachidonic acid from membrane phospholipids by phospholipase A2.
Indications
Different sources of media describe the Indications of 25122-46-7 differently. You can refer to the following data:
1. Clobetasol propionate is the 17-O-propionate ester of clobetasol and it derives from a clobetasol and a propionic acid. A potent corticosteroid, it is used to treat various skin disorders, including exzema and psoriasis.
Clobetasol propionate was patented in 1968 and came into medical use in 1978. It is available as a generic medication. Clobetasol propionate is used for the treatment of various skin disorders including eczema, herpes labialis, psoriasis, and lichen sclerosus. It is also used to treat several auto-immune diseases, including alopecia areata, lichen planus (auto immune skin nodules), and mycosis fungoides (T-cell skin lymphoma). It is used as first-line treatment for both acute and chronic GVHD of the skin.
2. Clobetasol propionate (Cormax, Temovate, Embeline, Olux) is one of the most
potent of the currently available agents and is indicated for short-term treatment of
inflammatory or hyperplastic disorders. It is a synthetic fluorinated corticosteroid.
It may cause a more rapid or prolonged response than other topical corticosteroids.
It is recommended that clobetasol have a maximum application of 60 g/week for
no longer than 14 days without occlusion and that it should not be used in children
below age 12.
Chemical Properties
White or almost white, crystalline powder.

Check Digit Verification of cas no
The CAS Registry Mumber 25122-46-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,1,2 and 2 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 25122-46:
(7*2)+(6*5)+(5*1)+(4*2)+(3*2)+(2*4)+(1*6)=77
77 % 10 = 7
So 25122-46-7 is a valid CAS Registry Number.
