Various basic esters of nitrogen (2) and carbocyclic (3 and 4) analogs of cannabinoids were synthesized using dicyclohexylcarbodiimide in methylene chloride. The compounds in the three series were studied in selected pharmacological tests in mice, rats, dogs, and cats. It was shown that making the basic ester from the phenol retains biological activity and can lead to a greater selectivity of action, particularly the antinociceptive activity. The most interesting esters were 5, 6, 10, and 14 in the nitrogen analogs series and 19 and 20 in the carbocyclic series. Compound 5 was more potent than codeine in the writhing, hot plate, and tail flick tests and is at present undergoing clinical testing. Compound 20 was very potent in the mouse audiogenic seizure test and is of interest as an anticonvulsant agent.

Maintenance of telomeres-specialized complexes that protect the ends of chromosomes-is provided by the enzyme complex telomerase, which is a key factor that is activated in more than 80% of cancer cells, but absent in most normal cells. Targeting telomere maintenance mechanisms could potentially halt tumour growth across a broad spectrum of cancer types. Telomeric ends of chromosomes consist of noncoding repeat sequences of guanine-rich DNA. These G-rich ends can fold into structures called G-quadruplexes. Stabilization of G-quadruplexes by small binding molecules called G4 ligands can prevent telomerase enzyme from maintaining telomere integrity in cancer cells. G-quadruplexes can exist in other parts of the genome too, especially within promoter sequences of oncogenes, and also be interesting drug targets. Here, we describe the development of a new series of novel bis-triazoles, designed to stabilize G-quadruplex structures selectively as G4 ligands. FRET assays showed two compounds to be moderately effective G4 binders, with particular affinity for the quadruplex formed by the Hsp90a promoter sequence, and good selectivity for G-quadruplex DNA vs. duplex DNA. However, CD spectroscopy failed to provide any information about the folding topology of the human telomeric G-quadruplex resulting from its interaction with one of the ligands. All the new ligands showed potent cell growth inhibitory properties against human colon and pancreatic cancer cell lines, as evidenced by the MTT assay; notably, they were more potent against cancer cells than in fetal lung fibroblasts. Docking studies were performed to rationalize the affinity of these ligands for binding to the telomeric parallel G-quadruplex DNA.
