Summary
Polynucleotide High Purification Technology (PN HPT™) and hyaluronic acid (HA) demonstrate significant antioxidant activity. The combination (PN HPT™ + HA) showed the strongest scavenging of reactive oxygen species (ROS), suggesting therapeutic potential.
Area of Science:
- Biochemistry
- Cell Biology
- Dermatology
Background:
- Oxidative stress, driven by reactive oxygen species (ROS), is a key factor in various pathological conditions.
- Identifying effective antioxidant compounds is crucial for developing new therapeutic strategies.
Purpose of the Study:
- To evaluate the ROS scavenging activity of Polynucleotide High Purification Technology (PN HPT™), alone and combined with hyaluronic acid (HA).
- To assess the dose- and time-dependent effects of these compounds on oxidative stress.
Main Methods:
- A cell-free fluorometric assay using Calcein-AM was employed to measure ROS generation.
- PN HPT™, HA, and PN HPT™ + HA were tested at various concentrations and time points under hydrogen peroxide-induced oxidative stress.
Main Results:
- All tested treatments (PN HPT™, HA, PN HPT™ + HA) significantly reduced ROS levels compared to the control.
- PN HPT™ + HA exhibited the most potent and consistent ROS-neutralizing activity across all tested conditions.
- The enhanced efficacy of PN HPT™ + HA suggests a synergistic interaction between the two components.
Conclusions:
- PN HPT™ and its combination with HA possess significant antioxidant properties.
- PN HPT™ + HA demonstrates strong potential as an antioxidative agent for therapeutic applications, including wound healing and tissue regeneration.

00:48¹H NMR of Labile Protons: Deuterium (²H) Substitution
This lesson illustrates the role of deuterium substitution in simplifying the NMR spectrum of compounds comprising labile protons. One method employed is the use of deuterium. Amongst the three isotopes of hydrogen, deuterium (2H) has a nucleus composed of one proton and one neutron. When the D2O solvent is added to a pure dry ethanol solution, its labile proton is substituted with deuterium.
01:20¹³C NMR: Distortionless Enhancement by Polarization Transfer (DEPT)
When proton-coupled carbon-13 spectra are simplified by a broadband proton decoupling technique, structural information about the coupled protons is lost. Distortionless enhancement by polarization transfer (DEPT) is a technique that provides information on the number of hydrogens attached to each carbon in a molecule. While the DEPT experiment utilizes complex pulse sequences, the pulse delay and flip angle are specifically manipulated. The resulting signals have different phases depending on...
01:20Aldehydes and Ketones with Water: Hydrate Formation
An oxygen-based nucleophile, like water, can undergo addition reactions with aldehydes and ketones. The reaction leads to the formation of hydrates, also referred to as 1,1-diols or geminal diols.
The formation of hydrates is a reversible reaction. Hydrate formation is influenced by steric and electronic factors accompanying the alkyl substituents on the carbonyl group: The rate of hydrate formation increases with a decrease in the number of alkyl groups attached to the carbonyl carbon. Hence,...

01:15Oxidations of Aldehydes and Ketones to Carboxylic Acids
Oxidation of aldehydes and ketones results in the formation of carboxylic acids. Aldehydes, bearing hydrogen next to the carbonyl group, are easily oxidized compared to ketones. This is because an aldehydic proton can easily be abstracted during oxidation.
Aldehydes readily undergo oxidation in strong oxidizing agents such as potassium permanganate and chromic acid. The oxidation can also be carried out using mild oxidizing agents such as silver oxide. In fact, aldehydes can be easily oxidized...

01:13Esters to Carboxylic Acids: Acid-Catalyzed Hydrolysis
Hydrolysis of esters under acidic conditions proceeds through a nucleophilic acyl substitution. In the presence of excess water, the reaction proceeds in a reversible manner, forming carboxylic acids and alcohols.
During hydrolysis, the ester is first activated towards nucleophilic attack through the protonation of the carboxyl oxygen atom by the acid catalyst. The protonation makes the ester carbonyl carbon more electrophilic. In the next step, water acts as a nucleophile and adds to the...

01:16Titration in Nonaqueous Solvents
Most acid-base titrations are performed in an aqueous medium. In aqueous titrations, water competes with weaker acids or bases for proton donation or acceptance, leading to ambiguous endpoints in the titration curve. Water also affects the partial ionization of weak acids or bases. For example, water accepts a proton from acetic acid to form hydronium and acetate ions. The hydronium ion formed is a stronger acid than acetic acid, and the acetate ion is a stronger base than water. As a result,...
