MS-1020 is a cell-permeable inhibitor of janus kinase 3 (JAK3), strongly inhibiting constitutive autophosphorylation of JAK3 in L540 cells when used at 30-50 μM. It is without effect on other JAK isoforms and several other kinases, including Src, Lyn, Akt, EGFR, and ERK1/2. Through its effects on JAK3, MS-1020 blocks phosphorylation of downstream signal transduction and activators of transcription isoforms, reducing the expression of anti-apoptotic genes, leading to cell death.

MS-1020 is a novel small molecule that selectively inhibits JAK3 activity
Br J Haematol 2010 Jan;148(1):132-43.PMID:19793252DOI:10.1111/j.1365-2141.2009.07925.x.
In order to identify Janus kinase/signal transducer and activator of transcription (JAK/STAT) signalling inhibitors, a cell-based high throughput screening was performed using a plant extract library that identified Nb-(alpha-hydroxynaphthoyl)serotonin called MS-1020 as a novel JAK3 inhibitor. MS-1020 potently inhibited persistently-active STAT3 in a cell type-specific manner. Further examination showed that MS-1020 selectively blocked constitutively-active JAK3 and consistently suppressed interleukin-2-induced JAK3/STAT5 signalling but not prolactin-induced JAK2/STAT5 signalling. Furthermore, MS-1020 affected cell viability only in cancer cells harbouring persistently-active JAK3/STATs, and in vitro kinase assays showed MS-1020 binds directly with JAK3, blocking its catalytic activity. Therefore, the present study suggested that this reagent selectively inhibits JAK3 and subsequently leads to a block in STAT signalling. Finally, MS-1020 decreased cell survival by inducing apoptosis via down-regulation of anti-apoptotic gene expression. These results suggest that MS-1020 may have therapeutic potential in the treatment of cancers harbouring aberrant JAK3 signalling.
