The present invention provides new physiological active substance erbstatin analogue compounds of a general formula (I), which have excellent tyrosine-specific protein-kinase inhibitory activity, antitumor activity and antimicrobial activity. ##STR1## (in which R.sup.1 represents a hydrogen atom, a lower alkanoyl group or a lower alkyl group; n represents a positive integer of 1 to 3; X represents a hydrogen atom or a halogen atom; Y represents a group of formula --CH.dbd.CH--NC, --CH.dbd.CH--NHR.sup.2 or --CH.sub.2 --CH.sub.2 --NHR.sup.2 (where R.sup.2 represents a formyl group or a lower alkanoyl group; with the exception of the cases where X is hydrogen atom, (R.sup.1 O).sub.n group is 2,5-dihydroxy group and Y is --CH.dbd.CH--NHCHO or --CH.sub.2 --CH.sub.2 --NHCHO). The present invention further provides a tyrosine-specific protein-kinase inhibitor, tumoricide or bactericide containing at least one compound of the said formula (I).
