Scytonemin - Wikipedia
Scytonemin is a secondary metabolite and an extracellular matrix (sheath) pigment synthesized by many strains of cyanobacteria, including Nostoc, Scytonema, Calothrix, Lyngbya, Rivularia, Chlorogloeopsis, and Hyella. [1]
Scytonemin: Unravelling major progress and prospects
2022年5月1日 · Scytonemin is the first well-defined small biological molecule to inhibit human polo-like kinase 1 (PLK1) [77], enabling it to induce apoptotic pathways in osteosarcoma cell lines after exposing the cells to scytonemin for 72 h, exhibiting a dose-dependent decrease in proliferation [78].
Scytonemin | C36H20N2O4 | CID 135473381 - PubChem
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. A UV-screening molecule produced by many strains of cyanobacteria. It has a role as a biological pigment, a bacterial metabolite and an ultraviolet filter.
Cyanobacterial Secondary Metabolite Scytonemin: A Potential ...
2019年8月26日 · Scytonemin is a lipid-soluble, highly stable, yellow–brown-coloured secondary metabolite that is accumulated in the extracellular polysaccharide sheath of several but not all members of cyanobacteria. Chemically, scytonemin is an indole alkaloid composed of two heterocyclic units symmetrically connected through a carbon–carbon bond.
伪枝藻素 - 百度百科
伪枝藻素（英语：Scytonemin）是一种 生物色素，由许多蓝细菌合成，包括Calothrix sp.、Lyngbya aestuarii等，最早在1849被人发现，但直到1993年才解析了其结构。 据信，伪枝藻素对细菌起到了 防晒油 的作用，吸收325-425nm的紫外线，并在250nm有个吸收峰，在暴露在紫外线的情况下才启动它的 生物合成。 若非注明，所有数据均出自一般条件（25 ℃，100 kPa）下。 伪枝藻素（英语：Scytonemin）是一种生物色素，由许多蓝细菌合成，包括Calothrix sp. …
The structure of scytonemin, an ultraviolet sunscreen pigment …
1993年9月15日 · Despite knowledge of the existence of the pigment called scytonemin for over 100 years, its structure has remained unsolved until now. This pigment, the first shown to be an effective, photo-stable ultraviolet shield in prokaryotes, is a novel dimeric molecule (molec. wt. 544) of indolic and phenolic subunits and is known only from the sheaths ...
Scytonemin: Unravelling major progress and prospects
2022年5月1日 · Scytonemin, a highly stable UV-protective pigment, synthesized by some cyanobacteria has become a striking target as an effective medicine and natural-ecofriendly sunscreen. However, its application in cosmetic/pharmaceutical industries has been restrained due to its incompetent productivity.
Scytonemin - an overview | ScienceDirect Topics
Scytonemin is a lipid-soluble yellow-brown dimeric pigment molecule that provides protection against UVR due to its capacity to absorb significantly at 384, 300, 278, and 252 nm and constitutes the second important class of UV-absorbing compounds in cyanobacteria.
Probing the in vivo biosynthesis of scytonemin, a cyanobacterial ...
2011年11月11日 · Scytonemin is a dimeric indole phenolic pigment found in the sheath of many cyanobacteria. This pigment absorbs UV radiation protecting subtending cyanobacterial cells from harmful effects. Based on scytonemin’s unique chemical structure, the pathway to its biosynthesis is uncertain, thus motivating the current investigation.
