The present invention relates to a new method for preparing 4,4'-(1-methyl-1,2- ethandiyl)-bis-(2,6-piperazinedione) of formula (I) or its enantiomers. More specifically this invention relates to a new process for preparing 4,4'-(1-methyl- 1,2- ethandiyl)-bis-(2,6-piperazinedione), which gives better yield and purity and involves new intermediate.
Solvent free, catalyst free, microwave or grinding assisted synthesis of bis-cyclic imide derivatives and their evaluation for anticancer activity
Cyclic imides are well known to be very important antitumor agents such as mitonafide and amonafide etc. Based on this fact, we have synthesized two series of cyclic imidederivatives containing two cyclic imide moiety in their structures (bis-cyclic imides) and screened them for in vitro anticancer activity against five human cancer cell lines i.e. breast (T47D), lung (NCl H-522), colon (HCT-15),
