Synthetic dimeric cinchona alkaloids against cancer

Synthetic, novel dimeric cinchona alkaloid compounds having potent cytotoxic activity against human cancer cells. The compounds are effective agents for inhibiting cellular proliferation, for example, in cancer cells. The compounds cause apoptotic cell death in and cause inhibition of clonogenic growth of human breast cancer, prostate cancer, leukemia, lymphoma cells at nanomolar concentrations. The chemical structure of the compound includes dimeric cinchona alkaloid and derivatives containing various groups attached in their structure. The compounds also possess hydroxy group functionality in the structure to enable the preparation of pharmaceutically applicable salts to enhance their solubility for ease of systemic administration in animals and in humans, for example, in cancer patients.

Methods for extraction, processing, and purification of a selected family of target compounds from cannabis

Disclosed are methods for separating, recovering, and purifying cannabidiolic acid (CBDA) salts from an organic solvent solution comprising a mixture of cannabinoids. The methods comprise solubilizing the mixture of cannabinoids in C5-C7 hydrocarbon solvents, adding thereto a selected amine to thereby precipitate a CBDA-amine salt therefrom, dissolving the recovered CBDA-amine salt in a selected solvent and then adding thereto a selected antisolvent to thereby recrystallizing a purified CBDA-amine salt therefrom. The recrystallized CBDA-amine salt may be decarboxylated to form a mixture of cannabidiol (CBD) and amine. The CBD amine mixture may be acidified to separate the amine from CBD. The recovered CBD may be concentrated to produce a highly purified CBD. Also disclosed are CBDA-amine salts produced with certain amines selected from groups of secondary amines, tertiary amines, diamines, amino alcohols, amino ethers, and highly basic amines.
