The present embodiment provides a compound represented by the formula (1):

Q-CHR.sub.2  (1)

(Q is a nitrogen-containing aliphatic group containing two or more tertiary nitrogens but no oxygen, and R is an aliphatic group containing a biodegradable group). From the compound in combination with other lipids such as a lipid capable of reducing aggregation, lipid particles can be formed. Further, the compound can be used for a pharmaceutical composition to deliver an activator into cells.

The present invention relates to new alkaline, preferably highly alkaline, cleaning solutions comprising surfactants with improved stability and cleaning performance under such conditions. It further relates to novel surfactants.

Biologically active cannabidiol analogs comprising a compound of the formula ##STR00001##
wherein one of R.sub.1 or R.sub.2 or both is/are the residue of a moiety formed by the reaction of an amino group of the amino acid ester of R.sub.1 or R.sub.2 or both with a dicarboxylic acid or a dicarboxylic acid derivative and the other R.sub.1 or R.sub.2 (in the case of the mono) is the residue of a dicarboxylic acid or dicarboxylic acid derivative or Hydrogen (H), (i.e. underivatized), and salts thereof. These CBD analogs are be useful in pain management in oncology and other clinical settings in which neuropathy is presented. Furthermore, these CBD-analogs are useful in blocking the addictive properties of opiates.
