Polymers02:34

Polymers

40.6K
The word polymer is derived from the Greek words “poly” which means “many” and “mer” which means “parts”. Polymers are long chains of molecules composed of repeating units of smaller molecules, known as monomers. They either occur naturally, such as DNA and proteins, or can be constructed synthetically, like plastics. They have varied structural characteristics, such as linear chains, branched chains, or complex networks, that contribute to the...

Peptide Bonds

82.6K
A peptide bond covalently attaches amino acids through a dehydration reaction. One amino acid's carboxyl group and another amino acid's amino group combine, releasing a water molecule. The resulting bond is the peptide bond. The products that such linkages form are peptides. As more amino acids join this growing chain, the resulting chain is a polypeptide. Each polypeptide has a free amino group at one end. This end has the N-terminal, or the amino-terminal, and the other end has a free...

Higher Mental Functions of Brain: Learning and Memory

1.9K
Memory is one of the most vital higher mental functions of the brain. Memory is closely related to learning because it enables us to retain information and experiences from our past to use them in our present life. It also helps us to remember facts, events, and skills, such as riding a bike or swimming. There are two types of memory — declarative memory, which involves memorizing facts or events, and procedural memory, which enables us to remember how to do something like writing or...

Cis-regulatory Sequences02:02

Cis-regulatory Sequences

11.6K
Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...

Uncertainty in Measurement: Accuracy and Precision03:37

Uncertainty in Measurement: Accuracy and Precision

100.5K
Scientists typically make repeated measurements of a quantity to ensure the quality of their findings and to evaluate both the precision and the accuracy of their results. Measurements are said to be precise if they yield very similar results when repeated in the same manner. A measurement is considered accurate if it yields a result that is very close to the true or the accepted value. Precise values agree with each other; accurate values agree with a true value.

Area of Science:

  • Polymer Chemistry
  • Materials Science
  • Drug Delivery

Background:

  • Peptides are known for their ability to solubilize drugs like photosensitizers.
  • Developing synthetic polymers that mimic peptide functionality is crucial for advanced drug formulations.

Purpose of the Study:

  • To synthesize functional precision polymers based on oligo(N-substituted acrylamide)s and oligo(2-substituted-α-hydroxy acid)s.

Main Methods:

  • Synthesizing monodisperse oligo(N-substituted acrylamide)s and oligo(2-substituted-α-hydroxy acid)s.
  • Translating side-chain functionality sequences from a well-studied peptide into polymer sequences.
  • Evaluating the drug solubilization and release characteristics of the synthesized polymers using meta-tetra(hydroxyphenyl)chlorin.

Main Results:

  • Successfully synthesized functional precision polymers with discrete sequences.
  • The resulting peptidomimetic polymers preserved the drug solubilization capabilities of the parent peptide.
  • Achieved up to 40% higher drug payloads and 27-times faster initial drug release in some cases.

Conclusions:

  • Functional precision polymers can effectively mimic and enhance the properties of therapeutic peptides for drug formulation.
  • These peptidomimetics offer a promising platform for improving drug delivery systems, particularly for photosensitizers.
