Summary
Fluorinated retinoids, useful in biological studies, can be labeled at various carbon positions or with trifluoromethyl groups. These labeled compounds aid in understanding protein interactions and isomerization mechanisms using fluorine-19 NMR spectroscopy.
Area of Science:
- Biochemistry
- Organic Chemistry
- Spectroscopy
Background:
- Retinoids are vital molecules in biological systems.
- Fluorination offers unique properties for studying retinoid behavior.
- Previous studies have explored various applications of fluorinated compounds.
Purpose of the Study:
- To review methods for preparing fluorinated retinoids.
- To summarize the applications of these compounds in biochemical studies.
- To highlight the utility of fluorine-19 NMR in analyzing protein-retinoid interactions.
Main Methods:
- Preparation of retinoids with fluorine labels at odd/even carbons and trifluoromethyl groups.
- Application of fluorine-19 NMR spectroscopy.
- Analysis of protein-bound retinoid species.
Main Results:
- Fluorinated retinoids facilitate elucidation of cis/trans isomerization mechanisms.
- Techniques reveal restricted rotation within protein binding pockets.

01:27Acne Infection
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...
02:59Cancer Prevention
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

01:32The Retina
The retina is a layer of nervous tissue at the back of the eye that transduces light into neural signals. This process, called phototransduction, is carried out by rod and cone photoreceptor cells in the back of the retina.
01:31Lipid-derived Compounds in the Human Body
Fats and lipids are crucial components in the human body. Some lipid-derived compounds, such as fat-soluble vitamins, eicosanoids, lipoproteins, and glycolipids, also play unique roles to support various biological processes .
Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin, delayed...

01:13Electrophilic Aromatic Substitution: Fluorination and Iodination of Benzene
Bromination and chlorination of aromatic rings by electrophilic aromatic substitution reactions are easily achieved, but fluorination and iodination are difficult to achieve. Fluorine is so reactive that its reaction with benzene is difficult to control, resulting in poor yields of monofluoroaromatic products. To address this, Selectfluor reagent is used as a fluorine source in which a fluorine atom is bonded to a positively charged nitrogen.
01:05Total Internal Reflection Fluorescence Microscopy
Total internal reflection fluorescence microscopy or TIRF is an advanced microscopic technique used to visualize fluorophores in samples close to a solid surface with a higher refractive index, such as a glass coverslip. TIRF only allows fluorophores in proximity to the solid surface to be excited. When light from a medium with a lower refractive index (such as air) hits the glass coverslip at a critical angle, the light undergoes total internal reflection stead of passing through the glass.
