, (2008/06/13)
The invention is directed to novel cyclopropylpyrroloindole-oligopeptide compounds which are useful as anticancer agents. The novel cyclopropylpyrroloindole-oligopeptide compounds have the following general structure: STR1 wherein, Het1 and Het2 are individually selected from the group consisting of pyrrole, imidazole, triazole, thiophene, furan, thiazole, oxazole and pyrazole, R is selected from the group consisting of a valence bond; a C1 -C6 alkyl; a C2 -C6 alkenyl; a C2 -C6 alkynyl; and an ortho, meta or para linked aromatic group, A is selected from the group consisting of a C1 -C6 alkyl group; an amidine or derivative thereof; a guanidine; a secondary, tertiary or quaternary ammonium salt; and a sulfonium salt, n is 0 to 3, and m is 0 to 3.

Novel 1,2-di(2-pyrrolyl)ethenes 5 and related compounds 8 have been prepared in good yield using the Wittig reaction.Although the Horner reaction can be used for the synthesis of 1,2-di(2-thienyl)- and 1,2-di(2-furyl)-ethenes, the procedure is not suitabl

The pyrrolate ion (5) is shown to produce N, N'-dipyrrolyl methane (4) when reacted with dichloromethane under conditions of weak counter-ion association. 1-Azoniafulvene ion (13) is sggested to be the key intermediate in this reaction.N,N'-dipyrrolyl methane (4) undergoes intramolecular oxidative coupling when treated with butyllithium and Cu(II)chloride, yielding the novel ring system of dipyrrolo-2H-imidazole (3).The latter upon reaction with methyl lithium forms the Hueckel-aromatic anion 2.Solutions of the lithium salt are stable for several days.Reaction of the dianion of 2,2'-bipyrrole (11) with dichloromethane doesi40 not produce 3, but a pyrrolophane-type dimer (12) having its two anticoplanar N,N'-bipyrrolediyl subunits arranged in a double layer and joined by a methylene group on each side.
