Tyrosine Kinase Inhibitor Development Services for Bladder Cancer
Tyrosine kinase inhibitors (TKIs) are a type of targeted therapy that functions by inhibiting the activity of tyrosine kinase enzymes, thereby impeding the growth of cancer cells. Alfa Cytology specializes in providing development services for tyrosine kinase inhibitors specifically designed for bladder cancer.
Introduction to Tyrosine Kinase Inhibitor
Tyrosine kinases phosphorylate specific amino acids on substrate enzymes, subsequently altering signal transduction pathways that lead to downstream changes in cellular biology. The downstream signal transduction triggered by TKs can modulate cell growth, migration, differentiation, apoptosis, and programmed cell death. Constitutive activation or inhibition of TKs through mutations or other mechanisms can disrupt normal signal cascades, potentially resulting in malignancy and other pathological conditions. Therefore, the blockade of these initial signals using TKIs can prevent the aberrant actions caused by mutated or dysfunctional TKs.
Below are listed various binding modes of TKIs.
|
Type I inhibitors |
Competitively bind to the ATP-binding site of active TKs. The arrangement of the DFG motif in type I inhibitors has the aspartate residue facing the catalytic site of the kinase. |
| Type II inhibitors |
The binding of type II inhibitors occurs primarily at the ATP-binding site, where they specifically target inactive kinases. In these inhibitors, the DFG motif extends outward from the ATP-binding site, allowing them to effectively interact with adjacent regions that would otherwise be inaccessible. |
| Type III inhibitors |
Do not interact with the ATP-binding pocket. Type III inhibitors exclusively bind to allosteric pockets adjacent to the ATP-binding region. |
| Type IV inhibitors |
Bind allosteric sites far removed from the ATP-binding pocket. |
| Type V inhibitors |
Kinase inhibitors that exhibit multiple binding modes. |
