ANTI-FUNGAL & cannabis studies completed 

Overview

Anti-fungal medicines are used to treat fungal infections, which are most commonly found on the skin, hair and nails.

Fungal infections seem to be present in the vast majority of cancer cases.  One study reported candidemia was demonstrated in 88% of cancer patients they looked at.  Just search on “fungal infections in patients with cancer” to see a long list of studies reporting an association between fungus and various cancers.

Biologically Active Cannabinoids from High-Potency Cannabis sativa

Abstract

Nine new cannabinoids (19) were isolated from a high-potency variety of Cannabis sativa. Their structures were identified as (±)-4-acetoxycannabichromene (1), (±)-3′′-hydroxy-Δ(4′′,5′′)-cannabichromene (2), (−)-7-hydroxycannabichromane (3), (−)-7R-cannabicoumarononic acid A (4), 5-acetyl-4-hydroxycannabigerol (5), 4-acetoxy-2-geranyl-5-hydroxy-3-n-pentylphenol (6), 8-hydroxycannabinol (7), 8-hydroxycannabinolic acid A (8), and 2-geranyl-5-hydroxy-3-n-pentyl-1,4-benzoquinone (9) through 1D and 2D NMR spectroscopy, GC-MS, and HRESIMS. The known sterol β-sitosterol-3-O-β-d-glucopyranosyl-6′-acetate was isolated for the first time from cannabis. Compounds 6 and 7 displayed significant antibacterial and antifungal activities, respectively, while 5 displayed strong antileishmanial activity.

(2), (-)-7-hydroxycannabichromane

(3), (-)-7R-cannabicoumarononic acid A

(4), 5-acetyl-4-hydroxycannabigerol

(5), 4-acetoxy-2-geranyl-5-hydroxy-3-n-pentylphenol

(6), 8-hydroxycannabinol

(7), 8-hydroxycannabinolic acid A

(8), and 2-geranyl-5-hydroxy-3-n-pentyl-1,4-benzoquinone

(9) through 1D and 2D NMR spectroscopy, GC-MS, and HRESIMS. The known sterol beta-sitosterol-3-O-beta-d-glucopyranosyl-6'-acetate was isolated for the first time from cannabis.

Compounds 6 and 7 displayed significant antibacterial and antifungal activities, respectively, while 5 displayed strong antileishmanial activity.
