Description
Scytonemin is a ring assembly obtained by 1,1'-coupling of two molecules of (3E)-3-[(4-hydroxyphenyl)methylidene]cyclopenta[b]indol-2(3H)-one. It is a UV-screening molecule produced by many strains of cyanobacteria.
Uses
Used in Pharmaceutical Industry:
Scytonemin is used as a UV-screening agent for its ability to protect cyanobacteria from harmful UV radiation. This property makes it a potential candidate for the development of sunscreens and other protective products for human use.
Used in Cosmetics Industry:
Scytonemin is used as an active ingredient in cosmetic products for its UV-protection capabilities. It can be incorporated into formulations to provide a natural and effective shield against the damaging effects of ultraviolet radiation.
Used in Environmental Protection:
Scytonemin is used as a protective agent for aquatic life, particularly in the context of eutrophication and harmful algal blooms. Its UV-screening properties can help mitigate the negative impacts of excessive sunlight exposure on sensitive ecosystems.
Used in Research and Development:
Scytonemin is used as a subject of study in various scientific fields, including microbiology, photobiology, and environmental science. Its unique structure and properties make it an interesting molecule for understanding the mechanisms of UV protection in cyanobacteria and potentially other organisms.
Check Digit Verification of cas no
The CAS Registry Mumber 152075-98-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,0,7 and 5 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 152075-98:
(8*1)+(7*5)+(6*2)+(5*0)+(4*7)+(3*5)+(2*9)+(1*8)=124
124 % 10 = 4
So 152075-98-4 is a valid CAS Registry Number.

On the photostability of scytonemin, analogues thereof and their monomeric counterparts

As a part of their sun-protective strategy, cyanobacteria produce the natural UV-screener scytonemin. Its accumulation in the extracellular sheaths allows the bacteria to thrive in inhospitable locations highly exposed to solar radiation. Scytonemin is often referred to as photostable and has been reported to be non-fluorescent. Taken together, these properties indicate inherently fast non-radiative relaxation processes. Despite these interesting traits, the photophysics of scytonemin is as yet almost completely unexplored. In this study, we have compared the steady-state photophysics of scytonemin itself and four derivatives thereof. Furthermore, the in vitro photostability of scytonemin was studied in different solvents using a solar simulation system. Scytonemin and the investigated derivatives demonstrated a more rapid photoinduced decay in comparison with two commercial UV-screening agents. The photostability could be modulated by varying the solvent, with the protic solvent ethanol providing the most stabilizing environment.
