Structure-based drug design of the EG5 inhibitor NVP-BQS481
Dirksen E Bussiere
Global Discovery Chemistry - Novartis Institutes for Biomedical Research, USA
S
everal biological functions, particularly chromosome segregation, require the generation of motile force. The generation
of this force relies heavily on a class of proteins known as motor proteins. Motor proteins such as Kinesin Spindle Protein
(KSP), also known as Eg5, utilize the energy derived from ATP hydrolysis to generate motile force. High-throughput screening
of Eg5 identified several hits which were non-competitive with ATP with micromolar IC50’s capable of inhibiting the motor
protein. Using structure-based drug design, these hits were progressed to NVP-BQS481, a clinical candidate with an IC50 of
700 picomolar. The talk will present the design concepts and optimization techniques used to advance the series to the pre-
clinical stage.
