NMS-E973 is a potent and selective inhibitor of HSP90. NMS-E973 binds to the ATP binding site of Hsp90α with a DC50 of <10 nM. NMS-E973 is able to cross the blood-brain barrier (BBB). Antitumor efficacy[1]. | [Biological Activity]
nms-e973 is a potent and selective inhibitor of heat shock protein 90 (hsp90) with dc50 value of < 10nm [1].since hsp90 plays an important role in the conformational maturation, stability and function of some oncogenic proteins, the inhibitors of hsp90 are developed as therapeutic for cancers. nms-e973 is a selective inhibitor of hsp90. it binds to hsp90α within the atp binding site with dc50 value of < 10nm. besides that, nms-e973 shows no effect on a panel of 52 various protein kinases such as abl, ack1, akt1 and alk. the ic50 value of it for hsc70 is > 10μm. nms-e973 exerts antiproliferation effects on a2780 tumor cell line and bt-474 breast cancer cell line with ic50 values of 69nm and 110nm, respectively. when treated with mice bearing a2780 xenografts, the intravenous administration of nms-e973 significantly inhibits tumor growth with tgi value of 53% at dose of 30mg/kg. moreover, nms-e973 also displays antitumor activity in tumors resistant to kinase inhibitors such as vemurafenib [1, 2]. | [in vivo]
NMS-E973 (60 mg/kg; i.v.) inhibits the growth of A375 tumors subcutaneously or intracranially implanted in mice[1].
NMS-E973 exhibits moderate elimination half-lives (5.55±1.07 h) due to high plasma clearance (39.9±1.70 mL/min/kg) combined with large volumes of distribution (5.83±3.18 L/kg) following intravenous administration (10 mg/kg) in mice[1]. | Animal Model: | Balb/c male nude mice (aged 6 to 8 weeks) xenografted with the A375 tumors[1] | | Dosage: | 60 mg/kg | | Administration: | Administered twice daily i.v. according to 2 schedules: (i) every other day for 12 days and (ii) 3 days on/1 day off/3 days on (3-1-3, one cycle). | | Result: | Both schedules resulted in tumor shrinkage and TGI of 74% and 89%, respectively. |
