A medicine containing as the active ingredient a triazine derivative represented by general formula (I), a solvate thereof, or a salt thereof and being useful as a hepatitis remedy, wherein R1 and R2 represent each independently hydrogen or (un)substituted alkyl, aralkyl or alkenyl, or NR1R2 represents a cyclic amino group which may bear, in addition to the pertinent nitrogen atom, nitrogen, oxygen or sulfur as the ring atom and may be substituted, provided the case where NR1R2 represents NH2 is excluded.
discovered that a mucosal protective drug, irsogladine, inhibits the Hsp90 folding machinery. In vitro fluorescence polarization assay and cell‐based mechanism study demonstrate that irsogladine binds to the ATP‐binding pocket in N‐terminal domain of Hsp90 and impairs the Hsp90 chaperoning function. Consequently, irsogladine induces the downregulation of Hsp90 client proteins including Her2, Akt, and
