Biochem/physiol Actions

MC1742 is a uracil-based hydroxyamide (UBHA) that acts as a subtype-selective histone deacetylases (HDACs) inhibitor (IC50: class I HDAC1/2/3/8 = 100/110/20/610 nM, class IIB HDAC6/10 = 7/40 nM, class IV HDAC11 = 100 nM, class IIA HDAC4/5/7/9 >50 μM). MC1742 exerts greater antiproliferation potency than SAHA in sarcoma cancer stem cell (CSC) cultures (MC1742/SAHA IC50 in μM = 0.25/1/RD, 1.12/1.13//MG-63, 1.4/3.92/SK-ES-1 post 72-hr treatment) and effectively reactivates HIV from latency (EC50 = 350 nM; JLAT 10.6 cells) by upregulating histone acetylation at the HIV promoter without activating T cells.

Current antiretroviral therapy can suppress HIV replication, increase CD4 count and result in increased lifespan. However, it cannot eradicate the virus due to the presence of latent provirus in cellular reservoirs, such as resting CD4+ T cells. Using combination latency-reversing

Musculoskeletal sarcomas are aggressive malignancies of bone and soft tissues often affecting children and adolescents. Histone deacetylase inhibitors (HDACi) have been proposed to counteract cancer stem cells (CSCs) in solid neoplasms. When tested in human osteosarcoma, rhabdomyosarcoma, and Ewing's sarcoma

The glycolytic-based metabolism of cancers promotes an acidic microenvironment that is responsible for increased aggressiveness. However, the effects of acidosis on tumour metabolism have been almost unexplored. By using capillary electrophoresis with time-of-flight mass spectrometry, we observed a significant metabolic
