Polymers with alkyl- or heteroalkyl -aryl backbone and pharmaceutical compositions incorporating same

A biologically active polymeric compound comprising an alkylaryl or heteroalkylaryl backbone having about 5 to about 50 repeating aromatic ring-containing units and which, according to the computer program marketed as SYBYL version 5.2 running on a DEC VAX 11/750 computer, is capable of forming a linear backbone having a helical secondary structure, and wherein the maximum diameter of the helical structure, as measured by the alkylaryl or heteroalkylaryl backbone, is less than 3 times greater than the maximum diameter of the aryl group of the alkylaryl or heteroalkylaryl backbone.
