ML-346 ist ein Aktivator der Hsp70-Expression und HSF-1-Aktivität mit einem EC50-Wert von 4,6 μM für Hsp70. ML-346 stellt die Proteinfaltung in Konformationskrankheitsmodellen ohne signifikante Zytotoxizität oder fehlende Spezifität wieder her. ML-346 induziert spezifische Erhöhungen von Genen und Proteineffektoren der Hitzeschockreaktion (HSR), einschließlich Chaperonen wie Hsp70, Hsp40 und Hsp27.

ML-346 is an activator of the heat shock response that induces the expression of the heat shock protein HSP70, with an EC50 value of 4.6µM[1]. ML-346 molecule covalently modified the cysteine (Cys) at position 208 of the active site of the housekeeping sorting enzyme A (SrtA) of Staphylococcus aureus, significantly reducing the virulence phenotype of Staphylococcus aureus[2]. ML-346 has been widely used in transplantation tumor models to promote tumor cell apoptosis and reduce tumor growth[3].
In vitro, ML-346 treatment (10µM) for 24 hours significantly inhibited the viability of MDA-MB-435 cells and reduced the activities of CDK7 and CDK9[4]. Treatment with 10µM ML-346 for 24 hours significantly inhibited the LC3 I/II conversion in A549 cells, and promoted the accumulation of p62 as well as a significant increase in the phosphorylation level of mTOR at the Ser2448 site[5]. 15µM of ML-346 pretreatment for 1 hour significantly inhibited the accumulation of sphingomyelin induced by V8 in Jurkat cells and the co-localization with Lysotracker Red[6]. 10µM of ML-346 pretreatment for 4 hours alleviated the mitochondrial damage and cell apoptosis induced by the combined action of Fumonisin B1 (FB1) and ochratoxin A (OTA) in pK-15 cells[7].

| Cell experiment [1]: | |
Cell lines | MDA-MB-435 cells |
Preparation Method | MDA-MB-435 cells were cultured in DMEM/F12 medium supplemented with 10% fetal bovine serum, 100U/ml penicillin, and 100μg/ml streptomycin at 37°C with 5% CO2 and 95% saturated atmospheric humidity. Cells were seeded into 96-well microplates at a density of 5×103 cells/ml for 24h. Various concentrations of ML-346 (0, 2.5, 5, and 10µM) were added to each well. After 24h of incubation, cell viability was analyzed. |
Reaction Conditions | 0, 2.5, 5, and 10µM; 24h |
Applications | ML-346 treatment significantly inhibited the cell viability of MDA-MB-435 cells in a dose-dependent manner. |
