Acciones bioquímicas o fisiológicas

Ispinesib (SB-715992) is a potent and highly selective kinesin spindle protein (KSP, KIF11, EG5) allosteric inhibtor that specifically inhibits microtubule (MT)-stimulated ATPase activity of KSP (Ki = 1.7 nM; 5 μM MT, 500 μM ATP, 0.75 nM human KSP), but not ubiquitous kinesin heavy chain KHC, neuronal kinesin KIF1A, or mitotic kinesins CENP-E, RabK6, MCAK, MKLP1. Ispinesib exhibits anti-cancer efficacy in cultures (GI50 = 45 nM/BT-474 & 19 nM/MDA-MB-468) and in cancer xenograft models in vivo (8 or 10 mg/kg q4d×3 ip. mice with MCF-7, HCC-1954, KPL4, BT-474 xenografts).

To uncover their contrasting mechanisms, antimitotic drugs that inhibit Eg5 (kinesin-5) were analyzed in mixed-motor gliding assays of kinesin-1 and Eg5 motors in which Eg5 "braking" dominates motility. Loop-5 inhibitors (monastrol, STLC, ispinesib, and filanesib) increased gliding speeds, consistent with

Ispinesib (SB-715992) is a potent inhibitor of kinesin spindle protein, a kinesin motor protein essential for the formation of a bipolar mitotic spindle and cell cycle progression through mitosis. Clinical studies of ispinesib have shown a 9% response rate in

Development of drug resistance during cancer chemotherapy is one of the major causes of chemotherapeutic failure for the majority of clinical agents. The aim of this study was to investigate the underlying molecular mechanism of resistance developed by the mitotic

The mitotic kinesin KSP (kinesin spindle protein, or Eg5) has an essential role in centrosome separation and formation of the bipolar mitotic spindle. Its exclusive involvement in the mitotic spindle of proliferating cells presents an opportunity for developing new anticancer

Intracellular tension activity plays a crucial role in cytotoxic brain edema and astrocyte swelling. Here, a few genetically encoded FRET-based tension probes were designed to detect cytoskeletal structural tension optically, including their magnitude and vectors. The astrocyte swelling resulted in
