The formation of polyamines from reaction of 3-amino-1,2,4-triazole, 3-AT, with Group 4 metallocene dichlorides
occurs rapidly employing the interfacial polycondensation reaction giving moderate yield and chain lengths.
MALDI MS produces ion fragments to six to nine units with good isotopic abundance matches. IR shows the
absence of the internal ring NH consistent with the formation of M-N bands and inclusion of bands from both the
metallocene and 3-AT units. NMR results are also consistent with the proposed repeat unit. The polymers show
good inhibition of a group of solid human cancer cell lines including breast, lung, prostrate, and pancreatic cancer
and glioblastomas brain cancer cell lines. Thus, it is a wide-ranging potential anticancer drug.
Keywords: 3-amino-1,2,4-triazole, 3-AT, group 4 metallocenes, brain cancer, breast cancer, pancreatic cancer, polyamines, group 4 metallocene polymers, interfacial polymerization, glioblastomas brain cancer.
