Y-320
Based on 7 publication(s) in Google Scholar
Y-320 is a potent, orally active phenylpyrazoleanilide immunomodulator. Y-320 inhibits IL-17 production by CD4 T cells stimulated with IL-15 with IC50 values of 20 to 60 nM. Y-320 enhances TP53, DMD, and COL17A1 PTC readthrough by G418 and increases cellular protein levels and protein synthesis. Y-320 concomitants use of with a low dose of Paclitaxel (HY-B0015) significantly sensitized multidrug resistance (MDR) tumors by inducing G2/M phase arrest and apoptosis. Y-320 can be used for research of rheumatoid arthritis (RA) and cancer.
