Definition:A pyridoindole that is 1,2,3,4-tetrahydro-5H-pyrido[4,3-b]indole which is substituted on the tetrahydropyridine nitrogen by a methyl group and on the indole nitrogen by a p-[N-(hydroxy)aminocarbonyl]benzyl group. It is a histone deacetylase 6 (HDAC6) inhibitor that is selective against all the other isozymes (1000-fold) except HDAC8 (57-fold).
