Abstract:
As promising colchicine binding site inhibitors, SMART and its analogues have attracted many research efforts in recent years. A large number of SMART analogues with different B-rings have been reported; however, the effects of B-ring on the bioactivity are still unclear so far. Herein, we speculated that the conformational preference caused by B-rings was crucial for active SMART analogues. Our assumption was supported by the molecular docking studies, molecular dynamic simulation and DFT computations of SMART and its analogues reported by other and our research groups. Moreover, several novel SMART analogues with different conformational preferences were designed and synthesized to disclose the conformation impacts, and the preliminary biological evaluation was in accordance with our assumption.

The chair form is the most stable and derives its name from its resemblance to the “easy chair.” In the chair conformation, two carbon atoms are arranged out-of-plane — one above and one below, minimizing the torsional strain. In the chair form, the bond angle is very close to the ideal...

When particles with different initial velocities collide, they induce deformation by applying equal and opposite impulses. At the point of maximum deformation, the particles move together with...
