Indole alkaloids are responsible for toxicity of
Phalaris pastures to sheep and cattle [l-3]. Several of these alkaloids are present in various species of Gramineae, Leguminosae and other plant families [4]. Simple indole bases such as 3-N,Ndimethylaminomethylindole (gramine)
5-methoxy-N,N-dimethyltryptamine (MOM2T, 2), 5- methoxytryptamine (MOT, 3) and N,-methyltryptamine (MT, 4)

...total alkaloid content varies between 0.02-1.19 of dry wt in Phalaris arundinacea [7]
and gramine concentration may reach up to 7 mmol/kg fr. wt in barley [S],

..Several plant secondary metabolites are thought to protect plants against insects and patho- gens. For example, hydroxamic acids from Gramineae have been suggested to protect wheat and maize against the European corn borer.

"Vedno znani po svoji lastnosti selektivne kelacije kovin, ki tvorijo stabilne snovi, zlasti s Cu2 +, Fe3 +, V5 +, UO22 +. Študirali so jih tudi za uresničevanje polimernih verig s kelatnimi lastnostmi, ki se uporabljajo pri selektivnem odstranjevanju težkih kovin [2] [3] Nekatere hidroksamske kisline, kot so SAHA, Vorinostat, PXD101 in Belinostatin, LAQ824 / LBH589 in trihostatin A, so inhibitorji HDAC in imajo lastnost da preprečijo rakaste tvorbe ".
