Beyond Sunscreen Multitarget Docking of Mycosporine-Like Amino Acids (MAAs) for Anti-aging, Neuroprotection, and Immunomodulation

Medinformatics
Mycosporine-like amino acids (MAAs) act as efficient photoprotective and antioxidant agents, safeguarding biological systems from ultraviolet-induced oxidative damage. Owing to their biocompatibility and stability, MAAs have gained significant attention as eco-friendly bioactives in cosmetic and dermatological formulations.

Expression of Mycosporine-like Amino Acids Biosynthetic Genes in the Chlamydomonas sp. Exposed to Radiofrequency

, 2013
Mycosporine-like 아미노산(MAAs)은 UV 흡수물질이며, 다양한 해양생물들은 MAAs의 합성과 축적을 통하여 환경 자외선의 직 간접적인 영향을 감소시키는 기능을 진화시켜 왔다. 이 연구에서 우리는 radiofrequency(RF) 발생장치를 제작하였고, 이를 미세조류 배양에 적용하였다. 0.35±0.05 mHz의 RF를 Chlamydomonas sp. 배양기에 공급하였고, 정해진 시간(0, 0.5, 1 및 2 시간)에 시료를 채취하였다.

Extraction and antioxidant capacity of mycosporine-like amino acids from red algae in Japan

Mycosporine-like amino acids (MAAs) are the natural UV-absorbing compounds with antioxidant activity found in microalgae and macroalgae. We collected red algae Asparagopsis taxiformis, Meristotheca japonica, and Polysiphonia senticulosa from Nagasaki ...

Ontogenetic change in the abundance of mycosporine-like amino acids in non-zooxanthellate coral larvae

, 2005
Although mycosporine-like amino acids (MAAs) have been extensively investigated in reef-building corals, the sources of these MAAs and the process of their interconversion remain a topic of interest.

UV-absorbing mycosporine-like amino acids in the eyes of temperate marine and freshwater fish species

Frontiers in Marine Science
Ultraviolet radiation (UVR) is the photochemically most reactive waveband of incident solar irradiation. Despite high absorption in aquatic environments, UVR causes numerous biochemical, genetic, and cytotoxic effects in aquatic organisms. To counteract UVR stress, many of those species are able to synthesize, accumulate, or acquire UV-sunscreen ...

Reversing the directionality of reactions between non-oxidative pentose phosphate pathway and glycolytic pathway boosts mycosporine-like amino acid production in Saccharomyces cerevisiae

Microbial Cell Factories
Background Mycosporine-like amino acids (MAAs) are a class of strongly UV-absorbing compounds produced by cyanobacteria, algae and corals and are promising candidates for natural sunscreen components.

Mycosporine-like amino acids (MAAs): chemical structure, biosynthesis and significance as UV-absorbing/screening compounds.

Indian journal of experimental biology, 2008
Continuous depletion of the stratospheric ozone layer has resulted in an increase in ultraviolet-B (UV-B; 280-315 nm) radiation on the earth's surface which inhibits photochemical and photobiological processes. However, certain photosynthetic organisms have evolved mechanisms to counteract the toxicity of ultraviolet or high photosynthetically active ...
