(a) SPR measurements for compounds 8, 10–22 on WT-HSC70-NBD were carried out in triplicate unless otherwise stated. Compounds did not bind to the S275W HSC70-NBD mutant. SPR Kd values are expressed as a mean ± standard deviation or standard error. aDuplicate measurement. bSingle measurement. cLigand efficiency is calculated using the SPR Kd. dNot Determined. (b) Synthesis of cyclopentylaminotriol analogues 23, 24 and 26 (c) SAR of cyclopentylaminotriol analogues. SPR measurements on WT-trHSC70 were carried out in triplicate. Compounds did not bind to the S275W HSC70-NBD mutant. SPR Kd values are expressed as a mean ± standard deviation or standard error. aLigand efficiency is calculated using the SPR Kd.
