1. Dear Drugs-Forum readers: We are a small non-profit that runs one of the most read drug information & addiction help websites in the world. We serve over 4 million readers per month, and have costs like all popular websites: servers, hosting, licenses and software. To protect our independence we do not run ads. We take no government funds. We run on donations which average $25. If everyone reading this would donate $5 then this fund raiser would be done in an hour. If Drugs-Forum is useful to you, take one minute to keep it online another year by donating whatever you can today. Donations are currently not sufficient to pay our bills and keep the site up. Your help is most welcome. Thank you.

    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 werw 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 anticovulsant agent.
