There is disclosed a pharmaceutical composition comprising as active ingredient a linked cyclic compound of general formula I,
Z - R - A - R' - Y (I)
in which Z and Y are independently cyclic polyamine moieties having from 9 to 32 ring members and from 3 to 8 amine nitrogens in the ring spaced by 2 or more carbon atoms from each other,
A is an aromatic or heteroaromatic moiety,
R and R' are each a substituted or unsubstituted alkylene chain or heteroatom containing chain.
or an acid addition salt or metal complex thereof, in admixture or association with a pharmaceutically acceptable diluent or carrier.

macrocyclic ring size was varied from 12 to 16 ring members. Depending upon the substitution of the phenylenebis(methylene) linker (para or meta), sub-micromolar anti-HIV activity was exhibited by analogs bearing macrocycles of 12-14 ring members but with varying cytotoxicity to MT-4 cells. Furthermore, while we found that identical macrocyclic rings are not required for activity, substituting an acyclic
9-tetramethyl homologues, and respective highercyclicoligomer(s) were synthesized by condensation of tetraethyl p-diethylbenzene-ω,ω,ω′,ω′-tetracarboxylate with 1,4-bis(bromomethyl)-benzene, and its 2,5-dimethyl and 2,3,5,6-tetramethyl homologues in presence of sodium hydride under high dilution condition, respectively. 5,6,8,9-Tetramethyl[3.3]paracyclophane was obtained by hydrolysis, decarboxylative
The Friedel–Crafts-type intramolecular allylic alkylation of simple arenes is performed in the presence of a catalytic amount of [Mo(II) (CO)4Br2]2 (2.5 mol%). The moisture-tolerant protocol provided a mild and direct access to a large library of functionalized 4-vinyl-1,2,3,4-tetrahydronaphthalenes in high yields.
