Herein we report novelhybridcompounds based on valproic acid and DNA-alkylating triazene moieties, 1, with therapeutic potential for glioblastoma multiforme chemotherapy. We identified hybridcompounds 1d and 1e to be remarkably more potent against glioma and more efficient in decreasing invasive cell properties than temozolomide and endowed with chemical and plasma stability. In contrast to temozolomide

The reaction of arenediazonium ions with aqueous formaldehyde–methylamine solution affords mixtures of the 3-hydroxymethyltriazenes, ArNNN(Me)CH2OH, and the previously unreported bis(triazenylmethyl)methyl-amines, ArNNN(Me)CH2N(Me)CH2N(Me)NNAr.

(hydroxymethyl)triazenes are very similar. Both methyl- and (hydroxymethyl)triazenes decompose on silica plates during TLC analysis to give products consistent with known diazo-migration reactions. The (hydroxymethyl)triazenes have pronounced antitumor activity against the TLX5 tumor in vivo; in vivo-in vitro bioassay experiments suggest that the (hydroxymethyl)triazenes exert their in vivo antitumor activity

highly invasive and resistant nature of GBM. Hybrid compounds may open new horizons within this challenge. The multicomponent therapeutic strategy here used resides on a combination of two repurposing drugs acting by different but potentially synergistic mechanisms, improved efficacy, and lower resistance effects. We synthesized a new hybrid compound (HYBCOM) by covalently binding a TMZ analogue to valproic
