Eg5 Inhibitors

Eg5 Inhibitor III, Dimethylenastron, acts as a potent disruptor of the Eg5 kinesin motor protein by targeting its ATPase activity. Its unique structural features allow for specific interactions with the motor domain, leading to a conformational change that impedes microtubule sliding. The compound exhibits a remarkable affinity for the binding site, resulting in altered reaction kinetics that significantly affect mitotic processes and cellular motility.

Eg5 Inhibitor IV, VS-83, is a selective antagonist of the Eg5 kinesin motor protein, characterized by its ability to interfere with microtubule dynamics. This compound engages in specific hydrogen bonding and hydrophobic interactions within the motor domain, leading to a stabilization of the inactive conformation. Its unique binding profile alters the energy landscape of the ATP hydrolysis cycle, effectively modulating the motor's function and impacting cellular transport mechanisms.

Ispinesib is a potent inhibitor of the Eg5 kinesin motor protein, distinguished by its unique binding affinity that disrupts the normal function of microtubules. It engages in specific van der Waals interactions and electrostatic contacts within the motor domain, promoting a conformational shift that hinders ATPase activity. This alteration in the kinetic parameters of the motor protein affects the dynamics of mitotic spindle assembly, showcasing its role in cellular mechanics.

Terpendole E acts as a selective inhibitor of the Eg5 kinesin motor protein, characterized by its ability to induce conformational changes in the protein's structure. It interacts through hydrophobic and hydrogen bonding interactions, stabilizing a non-functional state of Eg5. This disruption alters the microtubule dynamics, impacting the mitotic process. The compound's unique stereochemistry contributes to its specificity, influencing reaction kinetics and cellular transport mechanisms.
