Summary
This study reviews therapeutic agents that inhibit DNA synthesis for treating hyperproliferative diseases. It details mechanisms of action, resistance, and novel strategies targeting specialized DNA polymerases.
Area of Science:
- Biochemistry
- Pharmacology
- Molecular Biology
Background:
- Inhibiting DNA synthesis is a key therapeutic strategy for hyperproliferative diseases like cancer and viral infections.
- Current therapies include nucleoside analogs and DNA damaging agents.
Purpose of the Study:
- To review therapeutic agents that inhibit DNA synthesis.
- To discuss molecular mechanisms against chromosomal and mitochondrial DNA polymerases.
- To explore resistance mechanisms and novel therapeutic strategies.
Main Methods:
- Review of purine and pyrimidine nucleoside analogs.
- Analysis of DNA damaging agents (e.g., cisplatin, chlorambucil).
- Examination of molecular mechanisms of DNA polymerase inhibition and resistance.
Main Results:
- Two main categories of agents inhibit DNA synthesis: nucleoside analogs and DNA damaging agents.
- Mechanisms involve direct DNA polymerase inhibition or indirect inhibition via DNA modification.
- Specialized DNA polymerases play roles in resistance by bypassing DNA lesions.
Conclusions:
- Understanding DNA synthesis inhibition is crucial for treating hyperproliferative diseases.
- Targeting specialized DNA polymerases presents emerging therapeutic opportunities.

02:57Targeted Cancer Therapies
9.0K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

02:56Treatment Resistant Cancers
3.8K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

02:34Inhibition of Cdk Activity
6.1K
The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

00:55DNA Helicases
24.3K
DNA unwinding helicase enzymes are a type of motor protein. Motor proteins can translocate along filaments or polymers using energy generated from ATP hydrolysis. Helicases are involved in all the important cellular processes where DNA unwinding is required, such as DNA replication, repair, recombination, and transcription. They are present in all living organisms, but vary in their structure, function, and mechanism of action. For example, in prokaryotes, DnaB helicase binds and translocates...

01:10Drugs that Destabilize Microtubules
4.0K
Microtubules are dynamic structures and can be regulated by microtubule targeting agents (MTAs). Microtubule destabilizing drugs are a class of MTAs that destabilize and prevent microtubules' polymerization. Both natural and synthetic chemicals can be found under this class of drugs. Vincristine and vinblastine, two vinca alkaloids, and colchicine were among the first to be discovered. These drugs can affect cells in various ways, either by inducing a change in cell morphology, preventing...

02:37Restarting Stalled Replication Forks
6.4K
DNA replication is initiated at sites containing predefined DNA sequences known as origins of replication. DNA is unwound at these sites by the minichromosome maintenance (MCM) helicase and other factors such as Cdc45 and the associated GINS complex.The unwound single strands are protected by replication protein A (RPA) until DNA polymerase starts synthesizing DNA at the 5’ end of the strand in the same direction as the replication fork. To prevent the replication fork from falling apart,...
