Summary
Marine organisms like corals use mycosporine-like amino acids (MAAs) to protect against UV radiation. This research explores these natural sunscreens to develop new synthetic UV-blocking compounds for human skincare.
Area of Science:
- Biochemistry
- Marine Biology
- Photophysiology
Background:
- Shallow-water marine organisms possess natural mechanisms to mitigate UV radiation damage.
- Mycosporine-like amino acids (MAAs) are common UV-absorbing compounds in marine life, with absorption maxima between 310-360 nm.
- Corals, in particular, produce significant MAAs, indicating potential for UV protection applications.
Purpose of the Study:
- To review the biochemical photophysiology of tropical reef-building corals.
- To introduce a novel class of synthetic sunscreens, 1-alkyl-3-alkanoyl-1,4,5,6-tetrahydropyridines.
- To explore the development of synthetic sunscreens inspired by natural coral UV protection.
Main Methods:
- Overview of coral biochemical photophysiology.
- Development and synthesis of novel tetrahydropyridine compounds.
- Screening of sunscreen candidates for UV-absorbing properties.
Main Results:
- Identification of MAAs as key UV-protective compounds in corals.
- Successful synthesis of a new class of synthetic sunscreen candidates.
- Evaluation of several synthetic compounds for sunscreen suitability.
Conclusions:
- Coral MAAs offer a model for developing effective UV protection strategies.
- The newly developed synthetic sunscreens show promise for cosmetic applications.
- Further testing is underway to assess the potential of these compounds in human skincare products.

01:23Role of Skin in Vitamin D Synthesis
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin D3(cholecalciferol).

01:19Pigmentation
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

01:23Red Algae
Red algae, also known as rhodophytes, are primarily found in marine environments, though some species inhabit freshwater and terrestrial ecosystems. These organisms exist in both unicellular and multicellular forms, with some multicellular varieties reaching macroscopic sizes.As phototrophic organisms, red algae contain chlorophyll a; however, their chloroplasts lack chlorophyll b. Instead, they possess phycobiliproteins, which serve as major light-harvesting pigments, similar to those found in...
01:21Green Algae
Green algae, also referred to as chlorophytes, are different from red algae in having the chloroplasts containing chlorophylls a and b, which give them their distinct green hue. However, they lack phycobiliproteins, preventing them from developing the red or blue-green pigmentation seen in red algae. In terms of photosynthetic pigment composition, green algae closely resemble plants and share a close evolutionary relationship with them. Taxonomically Green algae belong to Phylum Chlorophyta in...
01:30Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

01:12Renewal of Skin Epidermal Stem Cells
The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular cells,...
