Abstract:
The vascular endothelial growth factor (VEGF) and its receptors have been implicated as key-factors in tumor angiogenesis and are major targets in cancer therapy. New oligomers which mimic the architecture of DNA-binding polyamides have been designed to target the hypoxia inducible factor (HIF-1alpha) binding site on the promoter of VEGF gene. These oligomers incorporate an increasing number of six-five fused rings such as hydroxybenzimidazole-imidazole, benzimidazole-pyrrole, benzimidazole-chlorothiophene, and imidazopyridine-pyrrole, and bind the VEGF hypoxia response element (HRE) 5'-TACGT-3' with high affinity and selectivity.

Types of Hypoxia
There are four primary types of hypoxia, each resulting from a different cause:
1. Anemic hypoxia: This type occurs due to insufficient oxygen delivery caused by a lack of red blood cells (RBCs) or RBCs with abnormal or...

Globular and Fibrous Proteins
Globular proteins are also known as spheroproteins and typically are approximately round in shape. They contain a mix of amino acid types and contain differing sequences in their primary structures. Globular proteins have many different functions, such as enzymes, cellular messengers, and molecular transporters. These roles often require the proteins to be...
