548-03-8 Usage
General Description
Protohypericin is a chemical compound found in the plant Hypericum perforatum, also known as St. John's wort. It is a precursor to hypericin, a well-known compound with potential medicinal properties. Protohypericin has been found to exhibit antioxidant activity and has the potential to be used in the treatment of various diseases, including cancer and viral infections. Research has also shown that protohypericin may have potential anti-inflammatory and anti-depressant effects. Its biological activities make it a promising candidate for further investigation in the field of natural medicine and pharmaceutical development.
Check Digit Verification of cas no
The CAS Registry Mumber 548-03-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,4 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 548-03:
(5*5)+(4*4)+(3*8)+(2*0)+(1*3)=68
68 % 10 = 8
So 548-03-8 is a valid CAS Registry Number.

Concerning the absorption and photochemical properties of an ω-4-dimethylaminobenzal hypericin derivative
Obermueller,Falk
, p. 1519 - 1526 (2007/10/03)
A hypericin derivative containing ω,ω′ -4-dimethylaminobenzal residues was shown to undergo an intramolecular [2 + 2] cycloaddition upon irradiation leading to a cyclobutane derivative whose main absorption band is hardly shifted as compared to hypericin. The corresponding ω-substituted derivative displayed a 34 nm bathochromic shift and a strongly reduced fluorescence quantum yield rendering it a nice candidate for a photodynamic therapy agent. Unfortunately, however, it produced virtually no photosensitized active oxygen species, making it thus unsuited for this purpose.
