The present invention relates to anti tumor compounds of formula (I) ArCH.sub.2 R.sup.1 (I) or a monomethyl or monoethyl ether thereof (the compound of formula (I) including these ethers may contain no more than 29 carbon atoms in total); ethers, esters thereof; acid addition salts thereof; wherein Ar is a fused tetracyclic aromatic ring system comprised of 5-membered and 6-membered rings and contains at least one heteroatom and 3 aromatic rings and a total of no more than 18 ring atoms, or a substituted derivative thereof; the heteroatom is preferably oxygen, sulfur or nitrogen; when it is nitrogen this is substituted by hydrogen, methyl or ethyl; R.sup.1 contains not more than eight carbon atoms and is a group ##STR1## wherein m is 0 or 1; R.sup.5 is hydrogen; R.sup.6 and R.sup.7 are the same or different and each is hydrogen or C.sub.1-5 alkyl optionally substituted by hydroxy; R.sup.8 and R.sup.9 are the same or different and each is hydrogen or C.sub.1-3 alkyl; ##STR2## is a five or six-membered saturated carbocyclic ring; R.sup.10 is hydrogen, methyl or hydroxymethyl; R.sup.11, R.sup.12 and R.sup.13 are the same or different and each is hydrogen or methyl; R.sup.14 is hydrogen, methyl, hydroxy, or hydroxymethyl.
The present invention relates to compounds of the formula (I)
ArCH₂NHR¹ (I)
or a monomethyl or monoethyl ether thereof, the compound of formula (I) including the said ethers containing no more than 29 carbon atoms in total; an ester thereof; a salt thereof;
wherein Ar is a ring system of formula
wherein
is a five-membered ring containing at least one heteroatom and two double bonds or a substituted derivative thereof or a resonance form thereof, the heteratom is preferably oxygen, sulphur or nitrogen substituted by hydrogen methyl or ethyl;
R¹ contains not more than eight carbon atoms and is a group
wherein m is 0 or 1;
R⁵ and R⁶ are the same or different and each is hydrogen or C1-3 alkyl optionally substituted by hydroxy;
R⁷ and R⁸ are the same or different and each is hydrogen or C1-3 alkyl;
-C-C is a five-or six-membered saturated carbocyclic ring;
R⁹ is hydrogen, methyl or hydroxymethyl;
R¹⁰, R¹¹ and R¹² are the same or different and each is hydrogen or methyl;
R¹³ is hydrogen, methyl, hydroxy or hydroxymethyl.
