stauprimide stauprimide stauprimide is a semi-synthetic analog of the staurosporine family of indolocarbazoles. stauprimide was first published in 1994 as part of an extensive structure-activity investigation to improve the selective inhibition of protein kinase c as a potential antitumor agent. more recently, stauprimide has been shown to increase the efficiency of the directed differentiation of mouse and human embryonic stem cells in synergy with defined extracellular signaling cues. stauprimide interacts with nme2 (puf) transcription factor to down-regulate c-myc expression, leading to differentiation of stem cells. stauprimide names preferred iupac name n-cyclopentadibenzo-as-indacen-14-yl]-n-methylbenzamide identifiers cas number 154589-96-5 y 3d model (jsmol) interactive image chemspider 24606051 pubchem cid 46245328 unii t7r6vv8wul y inchi inchi=1s/c35h28n4o5/c1-35-31(43-3)23(37(2)34(42)18-11-5-4-6-12-18)17-24(44-35)38-21-15-9-7-13-19(21)25-27-28(33(41)36-32(27)40)26-20-14-8-10-16-22(20)39(35)30(26)29(25)38/h4-16,23-24,31h,17h2,1-3h3,(h,36,40,41)/t23-,24-,31-,35+/m1/s1 smiles c12((c(o1)n3c4ccccc4c5c3c6n2c7ccccc7c6c8c5c(=o)nc8=o)n(c)c(=o)c9ccccc9)oc properties chemical formula c35h28n4o5 molar mass 584.632 g·mol−1 except where otherwise noted, data are given for materials in their standard state (at 25 °c , 100 kpa). infobox references
