生物活性

描述Kinesin-5（Eg5）,the product of Kif11 gene, also known as kinesin spindle protein, is a motor protein involved in the proper establishment of a bipolar mitotic spindle. Eg5 is one of the 45 different kinesins coded in the human genome of the kinesin motor protein superfamily^[1]. BRD9876 is the rigor inhibitor that locks Eg5 in a state with enhanced microtubules (MTs) binding, leading to bundling and stabilization of MTs. BRD9876 interacts with the tyrosine 104 residue that is part of the α4-α6 allosteric binding pocket. BRD9876 specifically targets microtubule-bound Eg5 and selectively inhibits myeloma over CD34 cells. BRD9876 has the potential for multiple myeloma (MM) research^[2].BRD9876 (10 μM; 24 hours) reveales rapid arrest of cells at the G2/M phase starting as early as 2h of treatment in MM1S cells.BRD9876 exhibits approximately 3-fold selectivity for MM1S myeloma cells (IC50=3.1 μM) over CD34+ derived hematopoietic cells (IC50=9.1 μM).BRD9876 (0.1, 1, 10, 100 uM) is able to overcome, in MM1S cells, stromal resistance of bone marrow stromal cells (BMSCs) from MM bone marrow aspirates but only minimal effects are observed with BRD9876 against primary MM cells.BRD9876 is completely ineffective at inhibiting the basal ATPase activity of Eg5, in contrast to loop L5-binding monastrol or α4/α6-binding BI8 which shows greater activity against basal Eg5 ATPase activity^[3].
