Novel Dioctatin derivatives and process for production thereof

摘要

The invention provides novel dioctatin derivatives, a process for the production thereof, novel dioctatin derivatives useful as aflatoxin production inhibitor, and a method for controlling aflatoxin pollution by the use of an aflatoxin production inhibitor containing one or more of the dioctatin derivatives. The invention relates to dioctatin derivatives characterized by being represented by the structural formula (I): wherein R1 and R2 are each hydrogen, CH3-(CH2)n-, (CH3)2CH-CH2-, or C6H5-CH2-; n is an integer of 2 to 6; X1 and X2 are each CH3 or hydrogen; and Y is 2-amino-2-butenoic acid or an amino acid residue, with the proviso that the cases wherein both R1 and R2 are CH3-(CH2)4-; X2 is hydrogen; and Y is 2-amino-2-butenoic acid are excepted.
