JG-98 是一种热休克蛋白 70(Hsp70)变构抑制剂，可与 Hsp70 上的保守位点紧密结合，打断 Hsp70-Bag3 相互作用。JG-98 影响癌细胞和肿瘤相关巨噬细胞，显示抗癌活性。
| 生物活性 | JG-98, an allostericheat shock protein70 (Hsp70)inhibitor, which binds tightly to a conserved site onHsp70and disrupts the Hsp70-Bag3 interaction. JG-98 shows anti-cancer activities affecting bothcancercells and tumor-associated macrophages[1][2][3]. |

体外研究
(In Vitro) | JG-98 (30 nM-30 μM; 72 hours) has antiproliferative activity across a range of cell lines with the EC50s between ~0.3 and 4 μM[2].
JG-98 (10 μM; 48 hours) activates apoptotic mediators (cleavage of caspase-3 and PARP) in MDA-MB-231 cells[1].
JG-98 destabilizes FoxM1 and relieves suppression of downstream effectors, including p21 and p27[2].
Cell Proliferation Assay[2] | Cell Line: | MCF-7, MDA-MB-231, A375, MeWo, HeLa, HT-29, SKOV3, Jurkat, mouse embryonic fibroblasts (MEF), MM1.R, INA6, RPMI-8226, JJN-3, U266, NCI-H929, L363, MM1.S, KMS11, LP-1, AMO-1, OPM1, OPM2 cells | | Concentration: | 30 nM-30 μM | | Incubation Time: | 72 hours | | Result: | Active against all of the lines tested, and the EC50s were variable (between ~0.3 μM and 4 μM). Normal MEFs and OPM1 and OPM2 were relatively less sensitive. |
Western Blot Analysis[1] | Cell Line: | MDA-MB-231 cells | | Concentration: | 10 μM | | Incubation Time: | 48 hours | | Result: | Incudes apoptotic mediators cleavage of caspase 3 and PARP. |

体内研究
(In Vivo) | JG-98 (3 mg/kg; i.p.; on days 0, 2, and 4) suppresses tumor growth in xenograft models bearing MCF7 and HeLa cells[2].
| Animal Model: | 6-week-old NCR mice (xenografts of MCF7 and HeLa cells)[2] | | Dosage: | 3 mg/kg | | Administration: | Intraperitoneal injection; on days 0, 2, and 4 | | Result: | Limited tumor growth, but somewhat less effectively. |
