TABLE 2.
Summary of known HSP60 inhibitorsa.
Class | Inhibitor | Effect | References |
Mizoribine | Binds to the HSP60 ATPase domain and inhibits the chaperoning activity of Hsp60–Hsp10 complex | Itoh et al., 1999; Tanabe et al., 2012 | |
Natural products | Epolactaene | Inhibits the chaperone activity of HSP60 with yet unclear mechanism | Nagumo et al., 2005; Meng et al., 2018 |
ETB (tert-butyl ester of epolactaene) | Interacts with Cys442 of HSP60 leading to potential allosteric modulation of the ATP binding pocket | Nagumo et al., 2005 | |
Myrtucommulone A (MC) | Interacts directly with HSP60 leading to aggregation and misfolding of cancer related proteins | Wiechmann et al., 2017 | |
Stephacidin B | Performs anticancer activities | Qian-Cutrone et al., 2002; Wulff et al., 2007 | |
Avrainvillamide | Anticancer activities | Fenical et al., 2000 | |
Synthetic compounds | O-carboranylphenoxyacetanilide | Binds to HSP60 and inhibits the hypoxia-inducible factor (HIF) activation | Ban et al., 2010 |
Gold (III) porphyrin complexes such as A prototype gold (III) complex [Au(TPP)Cl] (10) | Despite its poorly understood mechanisms, it suppresses HSP60 and performs significant anticancer activities | Lease et al., 2013; Teo et al., 2014; Hu et al., 2016 |
